  3. Reliability of natural gas cogeneration systems

    SciTech Connect (OSTI)

    1995-12-01

    Cogeneration systems fueled by natural gas exceed the reliability of most central station power generating units, according to a study conducted by RINC Corporation for Gas Research Institute (GRI). In the study, researchers obtained operating data from 122 natural gas cogeneration units nationwide representing 2,200 megawatts (MW) of capacity and nearly 2 million hours of operating time at 37 facilities. Units were grouped into categories reflecting size (from 60 kilowatts to 100 MW), type of system (gas engine or gas turbine technology), use of emission controls, and type of thermal application. Various types and sizes of gas systems reported average availability factors ranging from 90.0 to 95.8 versus a weighted average of 85.9 percent for fossil-fuel steam, nuclear, and gas-turbine-based central station power generating units. Comparisons are based on study data and data reported by the North American Electric Reliability Council for utility power plants. Gas cogeneration can improve utility operations because as a group the relatively small, dispersed cogeneration units are more reliable than one or more large central station units of similar capacity.

    This paper covers the addition of cogeneration to two distinct facilities. Case 1 is a large convention center in which overall utility costs had to be reduced. Case 2 is a large southeastern university that needed additional steam capacity. Each facility initially had different goals, but the solution is the same: cogeneration. This paper offers a step-by-step process by which cogeneration was proven to be the solution that each facility needed.

  5. Sour landfill gas problem solved

    1996-05-01

    In Broward County, Fla., near Pompano Beach, Waste Management of North America (WMNA, a subsidiary of WMX Technologies, Oak Brook, IL) operates the Central Sanitary Landfill and Recycling Center, which includes the country`s largest landfill gas-to-energy plant. The landfill consists of three collection sites: one site is closed, one is currently receiving garbage, and one will open in the future. Approximately 9 million standard cubic feet (scf) per day of landfill gas is collected from approximately 300 wells spread over the 250-acre landfill. With a dramatic increase of sulfur-containing waste coming to a South Florida landfill following Hurricane Andrew, odors related to hydrogen sulfide became a serious problem. However, in a matter of weeks, an innovative desulfurization unit helped calm the landfill operator`s fears. These very high H{sub 2}S concentrations caused severe odor problems in the surrounding residential area, corrosion problems in the compressors, and sulfur dioxide (SO{sub 2}) emission problems in the exhaust gas from the turbine generators.

    1985-01-01

    The purpose of this book is to assist in understanding cogeneration principles (including small power production), in evaluating cogeneration projects, and in making wise choices on cogeneration investments. Cogeneration presents an efficient way of utilizing limited energy resources because the same fuel source is used simultaneously to produce two forms of useful energy, including electricity and heat. Cogeneration also presents a good investment opportunity, for the prices of both electricity and heat and have been escalating manyfold during the past ten years. However, as with other investments, cogeneration involves market risks: the uneven and unpredictable interactions among the electric utility (the buyer), the cogenerator (the seller), and the public utility commission (the regulator) will largely determine the cogeneration market potential as well as the success of failure of many cogeneration projects. This book is intended to serve as a text on the perspicacity of cogeneration development; to identify the cogeneration market to provide guidelines on effective cogeneration system design, to evaluate cogeneration economics, to describe the electric utilities' and public utility commissions' roles in the cogeneration market, and to assist in making the cogeneration investment decision.

  1. INNOVATIVE HYBRID GAS/ELECTRIC CHILLER COGENERATION

    SciTech Connect (OSTI)

    Todd Kollross; Mike Connolly

    2004-06-30

    Engine-driven chillers are quickly gaining popularity in the market place (increased from 7,000 tons in 1994 to greater than 50,000 tons in 1998) due to their high efficiency, electric peak shaving capability, and overall low operating cost. The product offers attractive economics (5 year pay back or less) in many applications, based on areas cooling requirements and electric pricing structure. When heat is recovered and utilized from the engine, the energy resource efficiency of a natural gas engine-driven chiller is higher than all competing products. As deregulation proceeds, real time pricing rate structures promise high peak demand electric rates, but low off-peak electric rates. An emerging trend with commercial building owners and managers who require air conditioning today is to reduce their operating costs by installing hybrid chiller systems that combine gas and electric units. Hybrid systems not only reduce peak electric demand charges, but also allow customers to level their energy load profiles and select the most economical energy source, gas or electricity, from hour to hour. Until recently, however, all hybrid systems incorporated one or more gas-powered chillers (engine driven and/or absorption) and one or more conventional electric units. Typically, the cooling capacity of hybrid chiller plants ranges from the hundreds to thousands of refrigeration tons, with multiple chillers affording the user a choice of cooling systems. But this flexibility is less of an option for building operators who have limited room for equipment. To address this technology gap, a hybrid chiller was developed by Alturdyne that combines a gas engine, an electric motor and a refrigeration compressor within a single package. However, this product had not been designed to realize the full features and benefits possible by combining an engine, motor/generator and compressor. The purpose of this project is to develop a new hybrid chiller that can (1) reduce end-user energy

    1997-06-01

    The Albany Interim Landfill Gas Extraction and Mobile Power System project served three research objectives: (1) determination of the general efficiency and radius of influence of horizontally placed landfill gas extraction conduits; (2) determination of cost and effectiveness of a hydrogen sulfide gas scrubber utilizing Enviro-Scrub{trademark} liquid reagent; and (3) construction and evaluation of a dual-fuel (landfill gas/diesel) 100 kW mobile power station. The horizontal gas extraction system was very successful; overall, gas recovery was high and the practical radius of influence of individual extractors was about 50 feet. The hydrogen sulfide scrubber was effective and its use appears feasible at typical hydrogen sulfide concentrations and gas flows. The dual-fuel mobile power station performed dependably and was able to deliver smooth power output under varying load and landfill gas fuel conditions.

    To solve the shortage of gas and steam supply in the small towns of the country, a new gas steam cogeneration system has been developed. On the basis of the fundamental research on the system, a demonstration gas steam cogeneration system has been designed. As the phase 1 of the project, a 75t/h demonstration CFB boiler for gas steam cogeneration has been erected and operated at Yangzhong Thermal Power Plant of China. This paper introduces the first 75t/h demonstration CFB boiler for gas steam cogeneration. Due to the need of gas steam cogeneration process, the boiler has the features of high temperature cyclone separation, high solid recycle ratio, staged combustion and an external heat exchanger adjusting bed temperature and heat load. The operation results show that the boiler has wide fuel adaptability and the heating value of the coal changes from 14MJ/Kg to 25MJ/Kg. The heat load changes from 85t/h to 28t/h while steam parameter is maintained at the normal conditions. The combustion efficiency of the boiler attain 98%. The boiler design and operation experiences may be a guide to the design and operation of larger CFB units in the future.

    This research project focused on the mitigation of silica damage to engine-based renewable landfill gas energy systems. Characterization of the landfill gas siloxane contamination, combined with characterization of the silica deposits in engines, led to development of two new mitigation strategies. The first involved a novel method for removing the siloxanes and other heavy contaminants from the landfill gas prior to use by the engines. The second strategy sought to interrupt the formation of hard silica deposits in the engine itself, based on inspection of failed landfill gas engine parts. In addition to mitigation, the project had a third task to develop a robust sensor for siloxanes that could be used to control existing and/or future removal processes.

    1981-01-01

    In 1978, a landfill operator in Oregon became interested in the technical and economic feasibility of recovering the methane generated in the landfill for the refueling of vehicles. DOE awarded a grant for a site-specific feasibility study of this concept. This study investigated the expected methane yield and the development of a conceptual gas-gathering system; gas processing, compressing, and storage systems; and methane-fueled vehicle systems. Cost estimates were made for each area of study. The results of the study are presented. Reasoning that gasoline prices will continue to rise and that approximately 18,000 vehicles in the US have been converted to operate on methane, a project is proposed to use this landfill as a demonstration site to produce and process methane and to fuel a fleet (50 to 400) vehicles with the gas produced in order to obtain performance and economic data on the systems used from gas collection through vehicle operation.

    1998-07-01

    The basic design of a cogeneration facility implies much more than looking for a gas turbine generating set that matches the steam host heat demand, and making an economical evaluation of the project. Tractebel Energy Engineering (TEE) has designed, built and commissioned since the early nineties 350 MW of cogeneration facilities, mainly producing electricity and steam with natural gas fired gas turbines, which is the present most common option for industrial combined heat and power production. A standardized cogeneration design does not exist. Each facility has to be carefully adapted to the steam host's particular situation, and important technical issues have to be addressed at an early stage of plant design. Unexpected problems, expensive modifications, delays during execution of the project and possible long term operational limitations or drawbacks may result if these questions are left unanswered. This paper comments the most frequent questions on design values, required flexibility of the HRSG, reliability and backup, control system, connection to the grid

Black-Right-Pointing-Pointer Analytical framework to evaluate transition from active to passive gas control. Black-Right-Pointing-Pointer Focus on cover oxidation as an alternative means of passive gas control. Black-Right-Pointing-Pointer Integrates research on long-term landfill behavior with practical guidance. - Abstract: Municipal solid waste landfills represent the dominant option for waste disposal in many parts of the world. While some countries have greatly reduced their reliance on landfills, there remain thousands of landfills that require aftercare. The development of cost-effective strategies for landfill aftercare is in society's interest to protect human health and the environment and to prevent the emergence of landfills with exhausted aftercare funding. The Evaluation of Post-Closure Care (EPCC) methodology is a performance-based approach in which landfill performance is assessed in four modules including leachate, gas, groundwater, and final cover. In the methodology, the objective is to evaluate landfill performance to determine when aftercare monitoring and maintenance can be reduced or possibly eliminated. This study presents an improved gas module for the methodology. While the original version of the module focused narrowly on regulatory requirements for control of methane migration, the improved gas module also considers best available control technology for landfill gas in terms of greenhouse gas emissions, air quality, and emissions of odoriferous compounds. The improved module emphasizes the reduction or elimination of fugitive methane by considering the methane oxidation capacity of the cover system. The module also allows for the installation of biologically active covers or other features designed to enhance methane oxidation. A methane emissions model, CALMIM, was used to assist with an assessment of the methane oxidation capacity of

    Steinfield, G.; Sanderson, R.

    1998-02-01

    Landfill gas represents a significant fuel resource both in the US and worldwide. The emissions of landfill gas from existing landfills has become an environmental liability contributing to global warming and causing odor problems. Landfill gas has been used to fuel reciprocating engines and gas turbines, and may also be used to fuel carbonate fuel cells. Carbonate fuel cells have high conversion efficiencies and use the carbon dioxide present in landfill gas as an oxidant. There are, however, a number of trace contaminants in landfill gas that contain chlorine and sulfur which are deleterious to fuel cell operation. Long-term economical operation of fuel cells fueled with landfill gas will, therefore, require cleanup of the gas to remove these contaminants. The overall objective of the work reported here was to evaluate the extent to which conventional contaminant removal processes could be combined to economically reduce contaminant levels to the specifications for carbonate fuel cells. A pilot plant cleaned approximately 970,000 scf of gas over 1,000 hours of operation. The testing showed that the process could achieve the following polished gas concentrations: less than 80 ppbv hydrogen sulfide; less than 1 ppmv (the detection limit) organic sulfur; less than 300 ppbv hydrogen chloride; less than 20--80 ppbv of any individual chlorinated hydrocarbon; and 1.5 ppm sulfur dioxide.

    Highlights: • Young and aged leachate works accounted for 89.1% and 10.9% of 33.35 Gg CO{sub 2} yr{sup −1}. • Fresh leachate owned extremely low ORP and high organic matter content. • Strong CH{sub 4} emissions occurred in the fresh leachate ponds, but small in the aged. • N{sub 2}O emissions became dominant in the treatment units of both systems. • 8.45–11.9% of nitrogen was removed as the form of N{sub 2}O under steady-state. - Abstract: With limited assessment, leachate treatment of a specified landfill is considered to be a significant source of greenhouse gas (GHG) emissions. In our study, the cumulative GHG emitted from the storage ponds and process configurations that manage fresh or aged landfill leachate were investigated. Our results showed that strong CH{sub 4} emissions were observed from the fresh leachate storage pond, with the fluxes values (2219–26,489 mg C m{sup −2} h{sup −1}) extremely higher than those of N{sub 2}O (0.028–0.41 mg N m{sup −2} h{sup −1}). In contrast, the emission values for both CH{sub 4} and N{sub 2}O were low for the aged leachate tank. N{sub 2}O emissions became dominant once the leachate entered the treatment plants of both systems, accounting for 8–12% of the removal of N-species gases. Per capita, the N{sub 2}O emission based on both leachate treatment systems was estimated to be 7.99 g N{sub 2}O–N capita{sup −1} yr{sup −1}. An increase of 80% in N{sub 2}O emissions was observed when the bioreactor pH decreased by approximately 1 pH unit. The vast majority of carbon was removed in the form of CO{sub 2}, with a small portion as CH{sub 4} (<0.3%) during both treatment processes. The cumulative GHG emissions for fresh leachate storage ponds, fresh leachate treatment system and aged leachate treatment system were 19.10, 10.62 and 3.63 Gg CO{sub 2} eq yr{sup −1}, respectively, for a total that could be transformed to 9.09 kg CO{sub 2} eq capita{sup −1} yr{sup −1}.

    A high-throughput gasification system has been developed for the steam gasification of woody biomass to produce a fuel gas with a heating value of 475 to 500 Btu/SCF without using oxygen. Recent developments have focused on the use of bark and sawdust as feedstocks in addition to wood chips and the testing of a new reactor concept, the so-called controlled turbulent zone (CTZ) reactor to increase gas production per unit of wood fed. Operating data from the original gasification system and the CTZ system are used to examine the preliminary economics of biomass gasification/gas turbine cogeneration systems. In addition, a ''generic'' pressurized oxygen-blown gasification system is evaluated.

    An integrated desiccant/steam-injected gas-turbine system was evaluated as an industrial cogenerator for the production of electricity and dry, heated air for product drying applications. The desiccant can be regenerated using the heated, compressed air leaving the compressor. The wet stream leaves the regenerator at a lower temperature than when it entered the desiccant regenerator, but with little loss of energy. The wet stream returns to the combustion chamber of the gas-turbine system after preheating by exchanging heat with the turbine exhaust strewn. Therefore, the desiccant is regenerated virtually energy-free. In the proposed system, the moisture-laden air exiting the desiccant is introduced into the combustion chamber of the gas-turbine power system. This paper discusses various possible design configurations, the impact of increased moisture content on the combustion process, the pressure drop across the desiccant regenerator, and the impact of these factors on the overall performance of the integrated system. A preliminary economic analysis including estimated potential energy savings when the system is used in several drying applications, and equipment and operating costs are also presented.

  9. Investigation of Integrated Subsurface Processing of Landfill Gas and Carbon Sequestration, Johnson County, Kansas

    2007-03-31

    The Johnson County Landfill in Shawnee, KS is operated by Deffenbaugh Industries and serves much of metropolitan Kansas City. Refuse, which is dumped in large plastic-underlined trash cells covering several acres, is covered over with shale shortly after burial. The landfill waste, once it fills the cell, is then drilled by Kansas City LFG, so that the gas generated by anaerobic decomposition of the refuse can be harvested. Production of raw landfill gas from the Johnson County landfill comes from 150 wells. Daily production is approximately 2.2 to 2.5 mmcf, of which approximately 50% is methane and 50% is carbon dioxide and NMVOCs (non-methane volatile organic compounds). Heating value is approximately 550 BTU/scf. A upgrading plant, utilizing an amine process, rejects the carbon dioxide and NMVOCs, and upgrades the gas to pipeline quality (i.e., nominally a heating value >950 BTU/scf). The gas is sold to a pipeline adjacent to the landfill. With coal-bearing strata underlying the landfill, and carbon dioxide a major effluent gas derived from the upgrading process, the Johnson County Landfill is potentially an ideal setting to study the feasibility of injecting the effluent gas in the coals for both enhanced coalbed methane recovery and carbon sequestration. To these ends, coals below the landfill were cored and then were analyzed for their thickness and sorbed gas content, which ranged up to 79 scf/ton. Assuming 1 1/2 square miles of land (960 acres) at the Johnson County Landfill can be utilized for coalbed and shale gas recovery, the total amount of in-place gas calculates to 946,200 mcf, or 946.2 mmcf, or 0.95 bcf (i.e., 985.6 mcf/acre X 960 acres). Assuming that carbon dioxide can be imbibed by the coals and shales on a 2:1 ratio compared to the gas that was originally present, then 1682 to 1720 days (4.6 to 4.7 years) of landfill carbon dioxide production can be sequestered by the coals and shales immediately under the landfill.

    Highlights: Black-Right-Pointing-Pointer LFG emissions are measured at an abandoned landfill with highly organic waste. Black-Right-Pointing-Pointer Mean headspace and vent emissions are 0.240 and 0.074 l CH{sub 4}/m{sup 2} hr, respectively. Black-Right-Pointing-Pointer At sites with high food waste content, LFG generation drops rapidly after site closure. Black-Right-Pointing-Pointer The viability of LFG recovery for CDMs in developing countries is doubtful. - Abstract: This paper examines landfill gas (LFG) emissions at a large inactive waste disposal site to evaluate the viability of investment in LFG recovery through the clean development mechanism (CDM) initiative. For this purpose, field measurements of LFG emissions were conducted and the data were processed by geospatial interpolation to estimate an equivalent site emission rate which was used to calibrate and apply two LFG prediction models to forecast LFG emissions at the site. The mean CH{sub 4} flux values calculated through tessellation, inverse distance weighing and kriging were 0.188 {+-} 0.014, 0.224 {+-} 0.012 and 0.237 {+-} 0.008 l CH{sub 4}/m{sup 2} hr, respectively, compared to an arithmetic mean of 0.24 l/m{sup 2} hr. The flux values are within the reported range for closed landfills (0.06-0.89 l/m{sup 2} hr), and lower than the reported range for active landfills (0.42-2.46 l/m{sup 2} hr). Simulation results matched field measurements for low methane generation potential (L{sub 0}) values in the range of 19.8-102.6 m{sup 3}/ton of waste. LFG generation dropped rapidly to half its peak level only 4 yrs after landfill closure limiting the sustainability of LFG recovery systems in similar contexts and raising into doubt promoted CDM initiatives for similar waste.

  16. Integrating district cooling with cogeneration

    1996-11-01

    Chillers can be driven with cogenerated thermal energy, thereby offering the potential to increase utilization of cogeneration throughout the year. However, cogeneration decreases electric output compared to condensing power generation in power plants using a steam cycle (steam turbine or gas turbine combined cycle plants). The foregone electric production increases with increasing temperature of heat recovery. Given a range of conditions for key variables (such as cogeneration utilization, chiller utilization, cost of fuel, value of electricity, value of heat and temperature of heat recovered), how do technology alternatives for combining district cooling with cogeneration compare? This paper summarizes key findings from a report recently published by the International Energy Agency which examines the energy efficiency and economics of alternatives for combining cogeneration technology options (gas turbine simple cycle, diesel engine, steam turbine, gas turbine combined cycle) with chiller options (electric centrifugal, steam turbine centrifugal one-stage steam absorption, two-stage steam absorption, hot water absorption).

    Analysis and cost reduction of fuel cells is being promoted to achieve commercial on-site phosphoric acid fuel cells (on-site FC). However, for such cells to be effectively utilized, a cogeneration system designed to use the heat generated must be developed at low cost. Room heating and hot-water supply are the most simple and efficient uses of the waste heat of fuel cells. However, due to the short room-heating period of about 4 months in most areas in Japan, the sites having demand for waste heat of fuel cells throughout the year will be limited to hotels and hospitals Tokyo Gas has therefore been developing an on-site FC and the technology to utilize tile waste heat of fuel cells for room cooling by means of an absorption refrigerator. The paper describes the results of fuel cell cogeneration tests conducted on a double effect gas absorption chiller heater with auxiliary waste heat recovery (WGAR) that Tokyo Gas developed in its Energy Technology Research Laboratory.

    1998-07-01

    The facts that national electrical company Electricite de France (EDF) has a monopoly on electrical power production in France and an extensive installed base of nuclear power plants, explain the difficulty encountered in developing cogeneration technology in France. Cogeneration only really first appeared in this country in the early 1990's, with the liberalization of energy markets and the government's encouragement. Since then, the number of cogeneration plants has continuously increased and electrical generating capacity is now approximately 1,200 MWe. Turbine and reciprocating engines (most of which are natural gas fired) account respectively for about 55% and 45% of the installed power. Unlike other countries, such as Germany--which has about two thousand 500 kWe and smaller units--the future of low-power cogeneration in France is far from assured, and there are currently less than 10 such plants. To help develop this efficient technology for producing electrical power and hot water, the Ecole des Mines de Nantes purchased a 210 kWe cogeneration generator set in 1996. This facility provides all or part of the school's electrical and heat requirements during five months between November and March. This cogeneration facility is also used during the rest of the year to perform research experiments in the field of lean-burn natural gas combustion. Lastly, it is also used to provide training for industry in cogeneration technology. Within this context, work was undertaken to study the set's energy and emissions performance, in relation to such parameters as spark advance and air factor, and at various loads.

    Cogeneration is a well established process for supplying heat and electricity from a single fuel source. Its feasibility and implementation in any particular case depend on technical, economic and internal and external {open_quotes}cultural{close_quotes} factors, including government policies. This paper describes the current status of small scale industrial cogeneration in Australia. A model has been developed to analyse the technical and economic aspects of retrofitting gas turbine cogeneration in the size range 3 to 30MW to industrial sites. The model demonstrates that for typical Australian energy cost data, the payback and the size of the optimized cogeneration plant depend strongly on electricity buyback prices. Also reviewed are some of the {open_quotes}cultural{close_quotes} factors which often militate against an otherwise economic installation, and government policies which may retard cogeneration by concern about local air emissions or favor it as increasing efficiency of energy use and reducing greenhouse emissions. A case study of a small gas turbine plant in Australia is outlined. 2 refs., 2 figs.

    Research highlights: > Plants influence gas profile and methane oxidation in landfill covers. > Plants regulate water content and increase the availability of oxygen for methane oxidation. > Plant species with deep roots like alfalfa showed more stimulation of methane oxidation than plants with shallow root systems like grasses. - Abstract: Methane is an important greenhouse gas emitted from landfill sites and old waste dumps. Biological methane oxidation in landfill covers can help to reduce methane emissions. To determine the influence of different plant covers on this oxidation in a compost layer, we conducted a lysimeter study. We compared the effect of four different plant covers (grass, alfalfa + grass, miscanthus and black poplar) and of bare soil on the concentration of methane, carbon dioxide and oxygen in lysimeters filled with compost. Plants were essential for a sustainable reduction in methane concentrations, whereas in bare soil, methane oxidation declined already after 6 weeks. Enhanced microbial activity - expected in lysimeters with plants that were exposed to landfill gas - was supported by the increased temperature of the gas in the substrate and the higher methane oxidation potential. At the end of the first experimental year and from mid-April of the second experimental year, the methane concentration was most strongly reduced in the lysimeters containing alfalfa + grass, followed by poplar, miscanthus and grass. The observed differences probably reflect the different root morphology of the investigated plants, which influences oxygen transport to deeper compost layers and regulates the water content.

    The overall objective of this project, 'Strategies to Optimize Microbially-Mediated Mitigation of Greenhouse Gas Emissions from Landfill Cover Soils' was to develop effective, efficient, and economic methodologies by which microbial production of nitrous oxide can be minimized while also maximizing microbial consumption of methane in landfill cover soils. A combination of laboratory and field site experiments found that the addition of nitrogen and phenylacetylene stimulated in situ methane oxidation while minimizing nitrous oxide production. Molecular analyses also indicated that methane-oxidizing bacteria may play a significant role in not only removing methane, but in nitrous oxide production as well, although the contribution of ammonia-oxidizing archaea to nitrous oxide production can not be excluded at this time. Future efforts to control both methane and nitrous oxide emissions from landfills as well as from other environments (e.g., agricultural soils) should consider these issues. Finally, a methanotrophic biofiltration system was designed and modeled for the promotion of methanotrophic activity in local methane 'hotspots' such as landfills. Model results as well as economic analyses of these biofilters indicate that the use of methanotrophic biofilters for controlling methane emissions is technically feasible, and provided either the costs of biofilter construction and operation are reduced or the value of CO{sub 2} credits is increased, can also be economically attractive.

    The Waste-to-Energy Cogeneration Project at Centennial Park has allowed methane from the closed Centennial landfill to export excess power into the the local utility’s electric grid for resale. This project is part of a greater brownfield reclamation project to the benefit of the residents of Munster and the general public. Installation of a gas-to-electric generator and waste-heat conversion unit take methane byproduct and convert it into electricity at the rate of about 103,500 Mwh/year for resale to the local utility. The sale of the electricity will be used to reduce operating budgets by covering the expenses for streetlights and utility bills. The benefits of such a project are not simply financial. Munster’s Waste-to Energy Cogeneration Project at Centennial Park will reduce the community’s carbon footprint in an amount equivalent to removing 1,100 cars from our roads, conserving enough electricity to power 720 homes, planting 1,200 acres of trees, or recycling 2,000 tons of waste instead of sending it to a landfill.

    The overall objective of the work reported here was to evaluate the extent to which conventional contaminant removal processes could be combined to economically reduce contaminant levels to the specifications for carbonate fuel cells. The technical effort was conducted by EPRI, consultant David Thimsen, Kaltec of Minnesota, Energy Research Corporation (ERC) and Interpoll Laboratories. The Electric Power Research Institute (EPRI) made available two test skids originally used to test an ERC 30 kW carbonate fuel cell at the Destec Coal Gasification Plan in Plaquemine, LA. EPRI`s carbonate fuel cell pilot plant was installed at the Anoka County Regional Landfill in Ramsey, Minnesota. Additional gas cleaning equipment was installed to evaluate a potentially inexpensive, multi-stage gas cleaning process to remove sulfur and chlorine in the gas to levels acceptable for long-term, economical carbonate fuel cell operation. The pilot plant cleaned approximately 970,000 scf (27,500 Nm{sup 3}) of gas over 1,000 hours of operation. The testing showed that the process could achieve the following polished gas concentrations. Less than 80 ppbv hydrogen sulfide; less than 1 ppmv (the detection limit) organic sulfur; less than 300 ppbv hydrogen chloride; less than 20--80 ppbv of any individual chlorined hydrocarbon; and 1.5 ppm sulfur dioxide. These were the detection limits of the analytical procedures employed. It is probable that the actual concentrations are below these analytical limits.

  2. Advanced coal-fueled industrial cogeneration gas turbine system particle removal system development

    Stephenson, M.

    1994-03-01

    Solar Turbines developed a direct coal-fueled turbine system (DCFT) and tested each component in subscale facilities and the combustion system was tested at full-scale. The combustion system was comprised of a two-stage slagging combustor with an impact separator between the two combustors. Greater than 90 percent of the native ash in the coal was removed as liquid slag with this system. In the first combustor, coal water slurry mixture (CWM) was injected into a combustion chamber which was operated loan to suppress NO{sub x} formation. The slurry was introduced through four fuel injectors that created a toroidal vortex because of the combustor geometry and angle of orientation of the injectors. The liquid slag that was formed was directed downward toward an impaction plate made of a refractory material. Sixty to seventy percent of the coal-borne ash was collected in this fashion. An impact separator was used to remove additional slag that had escaped the primary combustor. The combined particulate collection efficiency from both combustors was above 95 percent. Unfortunately, a great deal of the original sulfur from the coal still remained in the gas stream and needed to be separated. To accomplish this, dolomite or hydrated lime were injected in the secondary combustor to react with the sulfur dioxide and form calcium sulfite and sulfates. This solution for the sulfur problem increased the dust concentrations to as much as 6000 ppmw. A downstream particulate control system was required, and one that could operate at 150 psia, 1850-1900{degrees}F and with low pressure drop. Solar designed and tested a particulate rejection system to remove essentially all particulate from the high temperature, high pressure gas stream. A thorough research and development program was aimed at identifying candidate technologies and testing them with Solar`s coal-fired system. This topical report summarizes these activities over a period beginning in 1987 and ending in 1992.

    Seven pilot-scale partitioning gas tracer tests (PGTTs) were conducted to assess the accuracy and reproducibility of this method for measuring water in municipal solid waste landfills. Tests were conducted in the same location over a 12-month period, and measured moisture conditions ranged from possible dry waste to refuse with a moisture content of 24.7%. The final moisture content of 24.7% was in reasonable agreement with gravimetric measurements of excavated refuse, where the moisture content was 26.5 {+-} 6.0CI%. Laboratory tests were used to assess the utility of the PGTT for measuring water in small pores, water sorbed to solid surfaces, and the influence of dry waste on PGTTs. These experiments indicated that when refuse surfaces are not completely solvated with water, PGTTs may produce misleading results (negative estimates) of water saturation and moisture content.

    1990-01-01

    Methane produced by refuse decomposition in a sanitary landfill can be recovered for commercial use. Landfill methane is currently under-utilized, with commercial recovery at only a small percentage of US landfills. New federal regulations mandating control of landfill gas migration and atmospheric emissions are providing impetus to methane recovery schemes as a means of recovering costs for increased environmental control. The benefits of landfill methane recovery include utilization of an inexpensive renewable energy resource, removal of explosive gas mixtures from the subsurface, and mitigation of observed historic increases in atmospheric methane. Increased commercial interest in landfill methane recovery is dependent on the final form of Clean Air Act amendments pertaining to gaseous emissions from landfills; market shifts in natural gas prices; financial incentives for development of renewable energy resources; and support for applied research and development to develop techniques for increased control of the gas generation process in situ. This paper will discuss the controls on methane generation in landfills. In addition, it will address how landfill regulations affect landfill design and site management practices which, in turn, influence decomposition rates. Finally, future trends in landfilling, and their relationship to gas production, will be examined. 19 refs., 2 figs., 3 tabs.

    Today, approximately 300 million standard cubic ft/day (mmscfd) of natural gas and 1600 MW of electricity are produced from the decomposition of organic waste at 519 U.S. landfills (EPA 2010a). Since landfill gas (LFG) is a renewable resource, this energy is considered renewable. When used as a vehicle fuel, compressed natural gas (CNG) produced from LFG consumes up to 185,000 Btu of fossil fuel and generates from 1.5 to 18.4 kg of carbon dioxide-equivalent (CO{sub 2}e) emissions per million Btu of fuel on a 'well-to-wheel' (WTW) basis. This compares with approximately 1.1 million Btu and 78.2 kg of CO{sub 2}e per million Btu for CNG from fossil natural gas and 1.2 million Btu and 97.5 kg of CO{sub 2}e per million Btu for petroleum gasoline. Because of the additional energy required for liquefaction, LFG-based liquefied natural gas (LNG) requires more fossil fuel (222,000-227,000 Btu/million Btu WTW) and generates more GHG emissions (approximately 22 kg CO{sub 2}e /MM Btu WTW) if grid electricity is used for the liquefaction process. However, if some of the LFG is used to generate electricity for gas cleanup and liquefaction (or compression, in the case of CNG), vehicle fuel produced from LFG can have no fossil fuel input and only minimal GHG emissions (1.5-7.7 kg CO{sub 2}e /MM Btu) on a WTW basis. Thus, LFG-based natural gas can be one of the lowest GHG-emitting fuels for light- or heavy-duty vehicles. This report discusses the size and scope of biomethane resources from landfills and the pathways by which those resources can be turned into and utilized as vehicle fuel. It includes characterizations of the LFG stream and the processes used to convert low-Btu LFG into high-Btu renewable natural gas (RNG); documents the conversion efficiencies and losses of those processes, the choice of processes modeled in GREET, and other assumptions used to construct GREET pathways; and presents GREET results by pathway stage.

    In order to understand the benefits of cogeneration -- the on site production of electricity and hot water -- it is beneficial to know the overall efficiency of the energy media presently being used when compared to cogeneration. Virtually every commercial and industrial establishment purchases their electricity from the local utility company and heat their water by using on site boilers and hot water heaters fired by natural gas or propane -- which they also purchase from an outside supplier. When on-site cogeneration is compared to purchased power the results in fuel usage efficiency are: cogeneration -- 89.2%; purchased power -- 52.6%. The overall result of on site, properly applied cogeneration is an economical, environmental, and conservational tool that preserves an establishment`s cash, helps reduce pollution and conserves a precious natural resource.

    1987-04-01

    The author argues that excess capacity can increase retail rates, but deferral riders which allow utilities to offer lower rates to customers who might otherwise turn to cogeneration would optimize existing generating capacity. The author notes that encouraging cogeneration is only one goal of the Public Utility Regulatory Policies Act, while efficient use of powerplant capability is of equal importance. There will still be opportunities for cogenerators under the Cogeneration Deferral Tariff if they are patient because the concept of the tariff is to defer, not preclude cogeneration.

  3. Improving cogeneration plant performance through effective maintenance strategies

    Sheikh, S.M.

    1998-12-31

    Gas-fired cogeneration plants supplying power and thermal energy make up an increasing percentage of new fossil generation capacity additions, both in the US and overseas. These plants are popular, not only because they cost less to build, but also because they are highly efficient and their operation and maintenance costs are lower than plants using the traditional coal-based Rankine cycle. One of the methods being used to contain the initial cost of building cogeneration plants is to minimize redundancy both in the quantity of spare equipment specified for the various systems in the plants and in the design capacity of individual components. The overall effect of such a strategy may lead to reduced reliability and availability of the cogeneration plant in the long term. Operating cogeneration plants present a variety of technologies, equipment, and operating practices. While newer cogeneration plants routinely operate at a reliability of 90% or higher, older plants may not be able to achieve such performance due to excessive equipment breakdowns or inadequate maintenance strategies. By not having the appropriate maintenance programs in place, even newer cogeneration plants are vulnerable to deteriorating reliability and availability in the long term. This paper describes mechanisms for directing maintenance resources toward reducing current maintenance costs while maintaining high availability without sacrificing long-term reliability. The maintenance strategies discussed are those that can provide the maximum benefits for improving cogeneration plant reliability, availability, capacity, cost control, and safety.

  4. The success of cogeneration in Europe

    SciTech Connect (OSTI)

    Hunschofsky, H.

    1998-10-01

    The European engineers take a different approach to designing cogeneration plants. Instead of building large gas turbines or combined cycle plants whose main target is to produce electricity and then trying to utilize as much heat as possible, European engineers target the replacement of the base heat supply of certain, small scale entities. By focusing on the annual heat demand graph, the basic layout for maximum utilization is determined. If a plant can use all or a majority of the electricity, the by-product, produced in this combined process, the perfect requirements are a given. Today cogeneration is one of the prime technologies available to achieve two valuable goals: efficient usage of limited resources and air pollution reduction. In every major European country there is a non-profit organization promoting the usage of cogeneration and acting as a platform for the various interests involved. These national institutions are members of Cogen Europe, a non-profit organization based in Brussels, Belgium, whose main focus is to promote cogeneration to a multinational level.

    Highlights: Bio-methane landfill emissions from different period (0, 4, 8, 16 weeks) MTB waste have been evaluated. Electrical energy recoverable from landfill gas ranges from 11 to about 90 kW h/tonne. Correlation between oxygen uptake, energy recovery and anaerobic gas production shows R{sup 2} ranging from 0.78 to 0.98. LCA demonstrate that global impact related to gaseous emissions achieve minimum for 4 week of MBT. - Abstract: The global gaseous emissions produced by landfilling the Mechanically Sorted Organic Fraction (MSOF) with different weeks of Mechanical Biological Treatment (MBT) was evaluated for an existing waste management system. One MBT facility and a landfill with internal combustion engines fuelled by the landfill gas for electrical energy production operate in the waste management system considered. An experimental apparatus was used to simulate 0, 4, 8 and 16 weeks of aerobic stabilization and the consequent biogas potential (Nl/kg) of a large sample of MSOF withdrawn from the full-scale MBT. Stabilization achieved by the waste was evaluated by dynamic oxygen uptake and fermentation tests. Good correlation coefficients (R{sup 2}), ranging from 0.7668 to 0.9772, were found between oxygen uptake, fermentation and anaerobic test values. On the basis of the results of several anaerobic tests, the methane production rate k (year{sup ?1}) was evaluated. k ranged from 0.436 to 0.308 year{sup ?1} and the bio-methane potential from 37 to 12 N m{sup 3}/tonne, respectively, for the MSOF with 0 and 16 weeks of treatment. Energy recovery from landfill gas ranged from about 11 to 90 kW h per tonne of disposed MSOF depending on the different scenario investigated. Life cycle analysis showed that the scenario with 0 weeks of pre-treatment has the highest weighted global impact even if opposite results were obtained with respect to the single impact criteria. MSOF pre-treatment periods longer than 4 weeks showed rather negligible variation in the global

    Highlights: • Compilation of methane generation potential of mechanical biological treated (MBT) municipal solid waste. • Impacts and kinetics of landfill gas production of MBT landfills, approach with differentiated half-lives. • Methane oxidation in the waste itself and in soil covers. • Estimation of methane emissions from MBT landfills in Germany. - Abstract: Within the scope of an investigation for the German Federal Environment Agency (“Umweltbundesamt”), the basics for the estimation of the methane emissions from the landfilling of mechanically and biologically treated waste (MBT) were developed. For this purpose, topical research including monitoring results regarding the gas balance at MBT landfills was evaluated. For waste treated to the required German standards, a methane formation potential of approximately 18–24 m{sup 3} CH{sub 4}/t of total dry solids may be expected. Monitoring results from MBT landfills show that a three-phase model with differentiated half-lives describes the degradation kinetics in the best way. This is due to the fact that during the first years of disposal, the anaerobic degradation processes still proceed relatively intensively. In addition in the long term (decades), a residual gas production at a low level is still to be expected. Most of the soils used in recultivation layer systems at German landfills show a relatively high methane oxidation capacity up to 5 l CH{sub 4}/(m{sup 2} h). However, measurements at MBT disposal sites indicate that the majority of the landfill gas (in particular at non-covered areas), leaves the landfill body via preferred gas emission zones (hot spots) without significant methane oxidation. Therefore, rather low methane oxidation factors are recommended for open and temporarily covered MBT landfills. Higher methane oxidation rates can be achieved when the soil/recultivation layer is adequately designed and operated. Based on the elaborated default values, the First Order Decay (FOD

    As the result of a cooperative effort between government, industry, and a major utility, an important cogeneration project became operational in July, 1988. At the Energy Technology Engineering Center (ETEC), a research, development and testing installation operated for the United States Department of Energy (DOE), a 26.9 megawatt turbine-generator added to the SCTI facility in a bottoming-cycle configuration recovers energy from the waste steam produced in the testing steam generators. This paper reports on this project, called Power Pak, which originated in 1980 with proposals to DOE for funding of a cogeneration addition, and encouragement by DOE to evaluate and pursue this and other energy conservation measures. This article presents a narrative history of the development of this project with lessons learned.

    An optimal operational planning method is proposed for cogeneration systems with thermal storage. The daily operational strategy of constituent equipment is determined so as to minimize the daily operational cost subject to the energy demand requirement. This optimization problem is formulated as a large-scale mixed-integer linear programming one, and it is solved by means of the decomposition method. Effects of thermal storage on the operation of cogeneration systems are examined through a numerical study on a gas engine-driven cogeneration system installed in a hotel. This method is a useful tool for evaluating the economic and energy-saving properties of cogeneration systems with thermal storage.

    Cogeneration is the simultaneous generation of two types of energy, usually electricity and thermal energy, from a single energy source such as natural gas or diesel fuel. Cogeneration systems can be twice (or more) as efficient than conventional energy systems since both the electricity and the available thermal energy produced as a by-product of the electric generation, are used. This study identified cogeneration technologies and equipment capable of meeting Department of Defense (DOD) requirements for generation of electrical and thermal energy and described a wide range of successful cogeneration system configurations potentially applicable to DOD energy plants, including: cogeneration system prime movers, electrical generating equipment, heat recovery equipment, and control systems. State of the art cogeneration components are discussed in detail along with typical applications and analysis tools that are currently available to assist in the evaluation of potential cogeneration projects. A basic analysis was performed for 55 DOD installations to determine the economic benefits of cogeneration to the DOD. The study concludes that, in general, cogeneration systems can be a very cost effective method of providing the military with its energy needs.

    Venice Park landfill was one of the first sites to be permitted under Michigan's proposed Public Act 641. PA 641 essentially changed the rules and regulations for landfills from the simple design of digging a hole and filling it. It also upgraded standards to those that are more sophisticated, including liners, leachate collection systems, and gas extraction systems. In 1992, methane gas from the landfill was collected into wells drilled into the trash varying in depth from 30-50 feet in depth. A vacuum pulls the gas from the trash into the wells, then through a piping system. The landfill uses about 80-100 kilowatts in-house. The remainder of the gas is sold to Consumers Power Co. which uses landfill gas to supply power to homes.

    A methodology for performance evaluation of a combined-cycle cogeneration system has been presented. Results for such a system using an advanced gas-turbine as the prime mover show that it is a very versatile system. It can produce a large power-to-heat ratio together with a high second-law efficiency over a wide range of process steam pressures. This work also demonstrates once again that the most appropriate and useful performance parameters for decision-making in cogeneration system design are the second-law efficiency and the power-to-heat ratio.

    Leading industrial companies and institutions are forever seeking new and better ways to reduce their expenses, reduce waste, meet environmental standards, and, in general, improve their bottom-line. One approach to achieving all of these goals is a 100 year-old concept, cogeneration. Many industrial and institutional plants need thermal energy, generally as steam, for manufacturing processes and heating. They also need electric power for motors, lighting, compressed air and air conditioning. Traditionally, these fundamental needs are met separately. Steam is produced with industrial boilers and electricity is purchased from a local utility company. However, these needs can be met at the same time with cogeneration, using the same heat source. Cogeneration is the concurrent production of electrical power and thermal energy from the same heat source. Large steam users commonly take advantage of cogeneration by using high pressure steam with a back pressure turbine to generate electricity, and extract lower pressure steam from the turbine exhaust for their process needs. This approach reduces their electric utility bills while still providing thermal energy for industrial processes. The result is also a more efficient process that uses less total heat and discharges less smoke up the stack. Newer technologies are making cogeneration opportunities available to smaller-sized thermal plants, and electric utility deregulation opportunities are causing many CEOs to seriously consider cogeneration in their manufacturing plants. Whether steam is created through cogeneration or separate generation, many opportunities exist to improve productivity in the distribution system, operation, and maintenance. These opportunities are captured by taking a systems approach, which is promoted by programs such as the Department of Energy's Steam Challenge.

    The sale of cogenerated process steam to industries could allow Arkansas Power and Light to expand its operation from power generation to manufactured energy at double the revenue. Rising oil prices and pending gas deregulation are forcing industrial customers to look for alternative fuel supplies. Utilities must seize the opportunity to sell cogenerated steam before prospective customers decide to generate their own power and steam, although a user survey shows that industry is reluctant to commit the capital at this time. AP and L's system will join combined-cycle cogeneration and coal gasification. Four figures display the data developed during AP and L's continuing feasibility studies. (DCK)

    Process designs and economics were developed to produce LNG and liquid carbon dioxide (CO{sub 2}) from landfill gas (LFG) using the Acrion CO{sub 2} wash process. The patented Acrion CO{sub 2} wash process uses liquid CO{sub 2} to absorb contaminants from the LFG. The process steps are compression, drying, CO{sub 2} wash contaminant removal and CO{sub 2} recovery, residual CO{sub 2} removal and methane liquefaction. Three flowsheets were developed using different residual CO{sub 2} removal schemes. These included physical solvent absorption (methanol), membranes and molecular sieves. The capital and operating costs of the flowsheets were very similar. The LNG production cost was around ten cents per gallon. In parallel with process flowsheet development, the business aspects of an eventual commercial project have been explored. The process was found to have significant potential commercial application. The business plan effort investigated the economics of LNG transportation, fueling, vehicle conversion, and markets. The commercial value of liquid CO{sub 2} was also investigated. This Phase 1 work, March 1998 through February 1999, was funded under Brookhaven National laboratory contract 725089 under the research program entitled ``Liquefied Natural Gas as a Heavy Vehicle Fuel.'' The Phase 2 effort will develop flowsheets for the following: (1) CO{sub 2} and pipeline gas production, with the pipeline methane being liquefied at a peak shaving site, (2) sewage digester gas as an alternate feedstock to LFG and (3) the use of mixed refrigerants for process cooling. Phase 2 will also study the modification of Acrion's process demonstration unit for the production of LNG and a market site for LNG production.

    This paper describes the selection of a cogeneration system for San Jose State University and how that system fits the needs of the University. The cogenerator plant is capable of meeting the total campus steam and electric requirements. When the plant is down for routine maintenance, backup is supplied by the existing boiler plant and the local electric utility. Power generated above the University's needs is sold to the utility. The relatively new Cheng cycle system was chosen for the plant. It has more flexibility than a simple cycle and greater electrical and steaming capacity than for the equivalent combined cycle system. An analysis showed that under the University's loads and rate structure, the Cheng cycle could provide realistic sizing and good financial returns. The design of the Cheng system is described.

    A cogeneration plant now under construction at an oil refinery in Martinez, California, is an example of how the energy industry has been responding to the fundamental economic and technological challenges it has been facing over the past ten years. The industry is re-examining cogeneration as one way of meeting the requirements of the Public Utilities Regulatory Policy Act. The new plant is located at Tosco Corporation's Avon Oil Refinery, 45 miles northeast of San Francisco. It was designed by Foster Wheeler to supply process steam for the refinery as well as for a water-treatment installation that will benefit the Contra Costa Water District. Electric power produced will be used primarily by the refinery, with the balance purchased by the Pacific Gas and Electric Company.

    Osaka Gas and Tokyo Gas have high expectations for natural-gas-fueled Solid Oxide Fuel Cell (SOFC) cogeneration systems. SOFC offers many advantages for on-site cogeneration systems, such as high electrical efficiency, high quality by-product heat and low emissions. They are now executing a joint development program with Westinghouse Electric Corporation (hereinafter called as WELCO). This program is aimed to verify a 25kW class SOFC cogeneration system. This system, which was modified by replacing previous zirconia porous support tube cells (PST cells) with newly designed air electrode supported cells (AES cells), commenced operation on March 21, 1995. The system has been successfully operated for 13,100 hours as of February 7, 1997. This paper presents the performance evaluation of the new AES cells and the results of system operation at WELCO.

    Cogeneration is a name given to energy systems that produce both electric power and useful thermal energy such as steam. While cogeneration markets have flourished in California, Texas, and some states, those in Maryland have not. A primary reason is that the industries that have been targeted in other states--e.g., oil refining, pulp and paper, chemicals, food processing--are not major elements of Maryland's industrial base. The study estimates the potential for future cogeneration in Maryland, both large units and small packaged systems, and assesses the potential impact of cogeneration systems on Maryland's energy needs between now and 2005. The study is presented in three volumes. Because of significant differences between large- and small-scale cogeneration, the analysis of these two systems was performed separately. This volume is a summary document presenting the findings from both studies.

    China`s energy production is largely dependent on coal. China currently ranks third in global CO{sub 2} emissions, and rapid economic expansion is expected to raise emission levels even further in the coming decades. Cogeneration provides a cost-effective way of both utilizing limited energy resources and minimizing the environmental impacts from use of fossil fuels. However, in the last 10 years state investments for cogeneration projects in China have dropped by a factor of 4. This has prompted this study. Along with this in-depth analysis of China`s cogeneration policies and investment allocation is the speculation that advanced US technology and capital can assist in the continued growth of the cogeneration industry. This study provides the most current information available on cogeneration development and market potential in China.

    1993-07-01

    This report describes the results of a study of thermal energy storage (TES) systems integrated with combined-cycle gas turbine cogeneration systems. Integrating thermal energy storage with conventional cogeneration equipment increases the initial cost of the combined system; but, by decoupling electric power and process heat production, the system offers two significant advantages. First, electric power can be generated on demand, irrespective of the process heat load profile, thus increasing the value of the power produced. Second, although supplementary firing could be used to serve independently varying electric and process heat loads, this approach is inefficient. Integrating TES with cogeneration can serve the two independent loads while firing all fuel in the gas turbine. An earlier study analyzed TES integrated with a simple-cycle cogeneration system. This follow-on study evaluated the cost of power produced by a combined-cycle electric power plant (CC), a combined-cycle cogeneration plant (CC/Cogen), and a combined-cycle cogeneration plant integrated with thermal energy storage (CC/TES/Cogen). Each of these three systems was designed to serve a fixed (24 hr/day) process steam load. The value of producing electricity was set at the levelized cost for a CC plant, while the value of the process steam was for a conventional stand-alone boiler. The results presented here compared the costs for CC/TES/Cogen system with those of the CC and the CC/Cogen plants. They indicate relatively poor economic prospects for integrating TES with a combined-cycle cogeneration power plant for the assumed designs. The major reason is the extremely close approach temperatures at the storage media heaters, which makes the heaters large and therefore expensive.

    Chillers can be driven with cogenerated thermal energy, thereby offering the potential to increase utilization of cogeneration throughout the year. However, cogeneration decreases electric output compared to condensing power generation. The foregone electric production increases with increasing temperature of heat recovery. The economics of alternatives for combining district cooling with cogeneration depend on many variables, including cogeneration utilization, chiller utilization, value of electricity, value and temperature of heat recovered and other factors.

    Need of pure water in areas of limited supply has driven the development of technologies to permit recycling of available water and to generate new water supplies by purifying saline resources. These technologies include sedimentation, filtration, softening, ion exchange, electrodialysis, reverse osmosis and distillation. Some of these developments serve needs of the power industry, others evolved due to the synergistic relationship between generating water and power. Large plant seawater desalination depend on this synergism for best economy, especially in Southern California and the Middle East. Applying new processes promise to drive down the cost of desalinated water, based on recently improved thermal efficiencies and on capital cost reductions. Cogeneration with these processes provides new mutual benefits for power and water technologies.

    The Pacific Northwest Laboratory (PNL) leads the U.S. Department of Energy`s Thermal Energy Storage (TES) Program. The program focuses on developing TES for daily cycling (diurnal storage), annual cycling (seasonal storage), and utility-scale applications [utility thermal energy storage (UTES)]. Several of these storage technologies can be used in a new or an existing power generation facility to increase its efficiency and promote the use of the TES technology within the utility and the industrial sectors. The UTES project has included a study of both heat storage and cool storage systems for different utility-scale applications. The study reported here has shown that an oil/rock diurnal TES system, when integrated with a simple gas turbine cogeneration system, can produce on-peak power for $0.045 to $0.06 /kWh, while supplying a 24-hour process steam load. The molten salt storage system was found to be less suitable for simple as well as combined-cycle cogeneration applications. However, certain advanced TES concepts and storage media could substantially improve the performance and economic benefits. In related study of a chill TES system was evaluated for precooling gas turbine inlet air, which showed that an ice storage system could be used to effectively increase the peak generating capacity of gas turbines when operating in hot ambient conditions.

    The utilities required to satisfy the university`s electrical, steam and chilled water needs are generated at the cogeneration facility located in the center of the main campus. The building housing this cogeneration facility was constructed in 1909, at this time it contained a cogeneration facility. The original facility produced 1/100 the capacity of the new facility, yet it was housed in the same area. This existing facility burned coal until April 16, 1932, when the last coal train to pass through the campus on the Colorado and Southern tracks whistled at the campus crossing at 8:45 in the evening. This signaled the end to the cogeneration era at the Boulder campus until September 27, 1992, when once again the university began commercial operation of the new cogeneration facility. Implementation of the Public Utilities Regulatory Policy Act of 1978 (PURPA) encouraged the development of cogeneration facilities due to their inherent energy efficiency. The federal government encouraged the development of cogeneration facilities by removing several major obstacles that historically deterred its full development. It was because of this act, coupled with the fact that the university is interested in energy conservation, reliable energy supply, has a large utility load and wishes to save money that they proceeded with their project. The paper describes the cogeneration system process and power options.

    Controlled landfilling is an approach to manage solid waste landfills, so as to rapidly complete methane generation, while maximizing gas capture and minimizing the usual emissions of methane to the atmosphere. With controlled landfilling, methane generation is accelerated to more rapid and earlier completion to full potential by improving conditions (principally moisture, but also temperature) to optimize biological processes occurring within the landfill. Gas is contained through use of surface membrane cover. Gas is captured via porous layers, under the cover, operated at slight vacuum. A field demonstration project has been ongoing under NETL sponsorship for the past several years near Davis, CA. Results have been extremely encouraging. Two major benefits of the technology are reduction of landfill methane emissions to minuscule levels, and the recovery of greater amounts of landfill methane energy in much shorter times, more predictably, than with conventional landfill practice. With the large amount of US landfill methane generated, and greenhouse potency of methane, better landfill methane control can play a substantial role both in reduction of US greenhouse gas emissions and in US renewable energy. The work described in this report, to demonstrate and advance this technology, has used two demonstration-scale cells of size (8000 metric tons [tonnes]), sufficient to replicate many heat and compaction characteristics of larger ''full-scale'' landfills. An enhanced demonstration cell has received moisture supplementation to field capacity. This is the maximum moisture waste can hold while still limiting liquid drainage rate to minimal and safely manageable levels. The enhanced landfill module was compared to a parallel control landfill module receiving no moisture additions. Gas recovery has continued for a period of over 4 years. It is quite encouraging that the enhanced cell methane recovery has been close to 10-fold that experienced with conventional

    The performance of a cogeneration system is easily affected by several factors; number and type of engines used in the system, the manner in which the system is operated, and the electric and thermal load profile that the system has to supply. Other factors which the energy analyst must also consider are the electric utility rate structure, the price of fuel used in the cogeneration system, and the working habits of the people at the site. The evaluation of cogeneration energy systems for the purpose of selecting a configuration with the best performance requires a great amount of effort. A computer program to analyze a cogeneration system would greatly reduce the effort needed to evaluate cogeneration systems. Realizing the need for such a tool, the Naval Civil Engineering Laboratory developed such a cogeneration analysis computer program, Civil Engineering Laboratory Cogeneration Analysis Program (CELCAP), for the purpose of evaluating the performance of cogeneration systems on a life-cycle operating cost basis.

    The Cogeneration Technology Altenatives Study (CTAS) provides data and information in the area of advanced energy conversion systems for industrial cogeneration applications in the 1985 to 2000 time period. Six current and thirty-six advanced energy conversion systems were defined and combined with appropriate balance-of-plant equipment. Twenty-six industrial processes were selected from among the high energy consuming industries to serve as a frame work for the study. Each conversion system was analyzed as a cogenerator with each industrial plant. Fuel consumption, costs, and environmental intrusion were evaluated and compared to corresponding traditional values. Various cogeneration strategies were analyzed and both topping and bottoming (using industrial by-product heat) applications were included. The advanced energy conversion technologies indicated reduced fuel consumption, costs, and emissions. Typically fuel energy savings of 10 to 25% were predicted compared to traditional on-site furnaces and utility electricity. With the variety of industrial requirements, each advanced technology had attractive applications. Overall, fuel cells indicated the greatest fuel energy savings and emission reductions. Gas turbines and combined cycles indicated high overall annual cost savings. Steam turbines and gas turbines produced high estimated returns. In some applications, diesels were most efficient. The advanced technologies used coal-derived fuels, or coal with advanced fluid bed combustion or on-site gasification systems. A description of the analysis employed and the results obtained are presented.

    Cogeneration due to potentially high efficiency can be very competitive in a deregulated market. Cogeneration can achieve extremely high levels of thermal efficiency, much higher than the most advanced and sophisticated combined cycle power plants generating only electric power. Thermal efficiency is one of the key factors in determining the power plant economics and feasibility. High efficiency means a lesser amount of fuel is used to generate the same amount of energy. In turn, burning a lesser amount of fuel means that fewer pollutants will be emitted. The paper first describes cogeneration plants, then discusses the importance of thermal load availability, cogeneration and distributed generation and other issues affecting cogeneration.

    The contemporary situation of our environment claims the sensitive approach to solving effective conversion of energy. Limited supplies of noble fuels and their prices evoke the need to use new combustion technologies of accessible fuels in given region without negative ecological influences. Energoproject participates in the preparation of the two projects in Ostrava-Karvin{acute a} black coal field in Czech Republic. The most effective usage of fuel energy is the combined of electricity and heat. If this physical principle is supported by a pressurized fluidized bed combustion (PFBC) one obtains a high electricity/heat ratio integrated steam-gas cycle on the basis of solid fuel. Cogeneration plant Toebovice is the dominant source (600 MW{sub th}) of Ostrava district heating system (1100 MW{sub th}). The high utilization of the installed output and utilization of the clean, compact and efficient of the PFBC technology is the principal but not the single reason for the selection of the Toebovice power plant as the first cogeneration plant for installation of the PFBC in Czech Republic. The boiler will burn black coal from the neighboring coal basin.

  4. Thermal tracking cogeneration -- A new or old idea? Cogeneration for multi-thermal loads

    SciTech Connect (OSTI)

    Geers, J.R.

    1998-04-01

    The idea of designing a cogeneration project that produces electricity based on the existing heating load is common to many cogeneration projects, but may be limiting the ultimate potential to the end user. Cogeneration which is developed as a power generator producing a small amount of steam for a host load is also common. However, the idea of designing a cogeneration facility to track multiple utility loads is not as common. Where the concept has been used, the projects have been very successful. This article has been written as a primer for professionals looking for ideas when performing analysis of a potential cogeneration project, and as a thought-provoker for end users. The authors will look at each of the possible loads, outline various technical considerations and factors, look at the factors impacting the economics, and lay out an approach that would provide assistance to those trying to analyze a cogeneration project without specialized engineering assistance. Regulatory, legal and financing issues are covered in other sources.

    Horak, W.C.

    1997-07-01

    The former Soviet Union made a major commitment to Cogeneration. The scale and nature of this commitment created a system conceptually different from Cogeneration in the west. The differences were both in scale, in political commitment, and in socio economic impact. This paper addresses some of the largest scale Cogeneration programs, the technology, and the residual impact of these programs. The integration of the Cogeneration and nuclear programs is a key focus of the paper. Soviet designed nuclear power plants were designed to produce both electricity and heat for residential and industrial uses. Energy systems used to implement this design approach are discussed. The significant dependence on these units for heat created an urgent need for continued operation during the winter. Electricity and heat are also produced in nuclear weapons production facilities, as well as power plants. The Soviets also had designed, and initiated construction of a number of nuclear power plants {open_quotes}ATETs{close_quotes} optimized for production of heat as well as electricity. These were canceled.

    Adoption of decentralized energy technologies will be crucial in the evolving structure of energy markets and the magnitude of future greenhouse gas emissions. This detailed analysis of the adoption of engine cogeneration gives insights into organizational decision making regarding the diffusion of a cost effective decentralized energy technology. Detailed site information on over 600 UK cogeneration installations was collected and analyzed for the six year period during which UK energy markets were in the process of deregulation. A detailed examination using standard investment criteria of the cogeneration schemes indicated that over 70% of investments were of questionable economic value to adopters. This was because these installations were below the calculated minimum economic size threshold. A key determinant of this size threshold was found to be the fixed costs of maintenance. Analysis of the financing of installations revealed that the largest fraction of poor investments occurred in energy services agreements between suppliers and adopters. The policy implications for decentralized energy technologies of a minimum size threshold and poor investment decisions by early adopters are discussed. Further research aims to explore postulated explanations for the observed decline in early adoption of UK engine cogeneration.

    2003-09-19

    BP West Coast Products, LLC (BP or the Applicant) proposes to construct and operate a nominal 720-megawatt (MW), natural-gas-fired, combined-cycle cogeneration facility next to the existing BP Cherry Point Refinery in Whatcom County, Washington. The Applicant also owns and operates the refinery, but the cogeneration facility and the refinery would be operated as separate business units. The cogeneration facility and its ancillary infrastructure would provide steam and 85 MW of electricity to meet the operating needs of the refinery and 635 MW of electrical power for local and regional consumption. The proposed cogeneration facility would be located between Ferndale and Blaine in northwestern Whatcom County, Washington. The Canadian border is approximately 8 miles north of the proposed project site. The Washington State Energy Facility Site Evaluation Council (EFSEC) has jurisdiction over the evaluation of major energy facilities including the proposed project. As such, EFSEC will recommend approval or denial of the proposed cogeneration facility to the governor of Washington after an environmental review. On June 3, 2002, the Applicant filed an Application for Site Certification (ASC No. 2002-01) with EFSEC in accordance with Washington Administrative Code (WAC) 463-42. On April 22, 2003, the Applicant submitted an amended ASC that included, among other things, a change from air to water cooling. With the submission of the ASC and in accordance with the State Environmental Policy Act (SEPA) (WAC 463-47), EFSEC is evaluating the siting of the proposed project and conducting an environmental review with this Environmental Impact Statement (EIS). Because the proposed project requires federal agency approvals and permits, this EIS is intended to meet the requirements under both SEPA and the National Environmental Policy Act (NEPA). The Bonneville Power Administration (Bonneville) and U.S. Army Corps of Engineers (Corps) also will use this EIS as part of their

    2004-07-01

    JAERI (Japan Atomic Energy Research Institute) has started the design study on the GTHTR300-cogeneration (GTHTR300C) aiming at producing electricity by a helium gas turbine and hydrogen by a thermochemical water splitting method (IS process method). The GTHTR300C is a block type High Temperature Gas-cooled Reactor (HTGR) with its reactor thermal power of 600 MW and outlet coolant temperature of 950 deg. C. The Intermediate Heat Exchanger (IHX) is located between the reactor pressure vessel (RPV) and the gas turbine system. The heat capacity of the IHX is 170 MW and is used for hydrogen production. The balance of the reactor thermal power is used for electric generation. The GTHTR300C is designed based on existing technologies for the High Temperature Engineering Test Reactor (HTTR) and the helium turbine power conversion technology under development for the Gas Turbine High Temperature Reactor (GTHTR300). This paper describes the deployment of the GTHTR300C together with the original design features and advantages of the system. (authors)

  18. Decentralised optimisation of cogeneration in virtual power plants

    2010-04-15

    Within several projects we investigated grid structures and management strategies for active grids with high penetration of renewable energy resources and distributed generation (RES and DG). Those ''smart grids'' should be designed and managed by model based methods, which are elaborated within these projects. Cogeneration plants (CHP) can reduce the greenhouse gas emissions by locally producing heat and electricity. The integration of thermal storage devices is suitable to get more flexibility for the cogeneration operation. If several power plants are bound to centrally managed clusters, it is called ''virtual power plant''. To operate smart grids optimally, new optimisation and model reduction techniques are necessary to get rid with the complexity. There is a great potential for the optimised management of CHPs, which is not yet used. Due to the fact that electrical and thermal demands do not occur simultaneously, a thermally driven CHP cannot supply electrical peak loads when needed. With the usage of thermal storage systems it is possible to decouple electric and thermal production. We developed an optimisation method based on mixed integer linear programming (MILP) for the management of local heat supply systems with CHPs, heating boilers and thermal storages. The algorithm allows the production of thermal and electric energy with a maximal benefit. In addition to fuel and maintenance costs it is assumed that the produced electricity of the CHP is sold at dynamic prices. This developed optimisation algorithm was used for an existing local heat system with 5 CHP units of the same type. An analysis of the potential showed that about 10% increase in benefit is possible compared to a typical thermally driven CHP system under current German boundary conditions. The quality of the optimisation result depends on an accurate prognosis of the thermal load which is realised with an empiric formula fitted with measured data by a multiple regression method. The key

  1. Phytoremediation of landfill leachate

    2006-07-01

    Leachate emissions from landfill sites are of concern, primarily due to their toxic impact when released unchecked into the environment, and the potential for landfill sites to generate leachate for many hundreds of years following closure. Consequently, economically and environmentally sustainable disposal options are a priority in waste management. One potential option is the use of soil-plant based remediation schemes. In many cases, using either trees (including short rotation coppice) or grassland, phytoremediation of leachate has been successful. However, there are a significant number of examples where phytoremediation has failed. Typically, this failure can be ascribed to excessive leachate application and poor management due to a fundamental lack of understanding of the plant-soil system. On balance, with careful management, phytoremediation can be viewed as a sustainable, cost effective and environmentally sound option which is capable of treating 250 m{sup 3} ha{sup -1} yr{sup -1}. However, these schemes have a requirement for large land areas and must be capable of responding to changes in leachate quality and quantity, problems of scheme establishment and maintenance, continual environmental monitoring and seasonal patterns of plant growth. Although the fundamental underpinning science is well understood, further work is required to create long-term predictive remediation models, full environmental impact assessments, a complete life-cycle analysis and economic analyses for a wide range of landfill scenarios.

  2. Cooling tower environmental considerations for cogeneration projects

    Careful consideration must be given to the potential environmental impacts resulting from cooling tower operations in cogeneration projects. Concerns include visible plumes, fogging and icing of nearby roadways, emissions, water use, aesthetics, and noise. These issues must be properly addressed in order to gain public acceptance and allow for easier permitting of the facility. This paper discusses the various evaporative type cooling tower technologies from an environmental standpoint. In addition, typical concerns and questions raised by the public are presented, along with suggested guidelines for addressing these concerns. The use of modeling to predict the potential environmental impacts from cooling tower operations is sometimes required by regulatory agencies as a condition for obtaining approval for the facility. This paper discusses two of the models that are currently available for predicting cooling tower environmental impacts such as fogging, icing, salt deposition, and visible plumes. The lack of standardized models for cooling tower noise predictions, and the means by which the modeling requirements may be achieved are also addressed. An overview of the characteristics of cooling tower noise, the various measures used for noise control and the interdependency of the control measures and other cooling tower performance parameters are presented. Guidance is provided to design cost effective, low noise installations. The requirements for cooling tower impact assessments to support permitting of a cogeneration facility are also presented.

    Highlights: • This study tracked chemical changes of wood and paper in landfills. • A decomposition index was developed to quantify carbohydrate biodegradation. • Newsprint biodegradation as measured here is greater than previous reports. • The field results correlate well with previous laboratory measurements. - Abstract: The objective of this study was to investigate the decomposition of selected wood and paper products in landfills. The decomposition of these products under anaerobic landfill conditions results in the generation of biogenic carbon dioxide and methane, while the un-decomposed portion represents a biogenic carbon sink. Information on the decomposition of these municipal waste components is used to estimate national methane emissions inventories, for attribution of carbon storage credits, and to assess the life-cycle greenhouse gas impacts of wood and paper products. Hardwood (HW), softwood (SW), plywood (PW), oriented strand board (OSB), particleboard (PB), medium-density fiberboard (MDF), newsprint (NP), corrugated container (CC) and copy paper (CP) were buried in landfills operated with leachate recirculation, and were excavated after approximately 1.5 and 2.5 yr. Samples were analyzed for cellulose (C), hemicellulose (H), lignin (L), volatile solids (VS), and organic carbon (OC). A holocellulose decomposition index (HOD) and carbon storage factor (CSF) were calculated to evaluate the extent of solids decomposition and carbon storage. Samples of OSB made from HW exhibited cellulose plus hemicellulose (C + H) loss of up to 38%, while loss for the other wood types was 0–10% in most samples. The C + H loss was up to 81%, 95% and 96% for NP, CP and CC, respectively. The CSFs for wood and paper samples ranged from 0.34 to 0.47 and 0.02 to 0.27 g OC g{sup −1} dry material, respectively. These results, in general, correlated well with an earlier laboratory-scale study, though NP and CC decomposition measured in this study were higher than

    Cogeneration, the utilization of heat created while producing electricity from fossil fuels, is by no means a new technology. In 1926, 71 years ago, a brochure from MAN in Germany showed a heat recovery system for diesel engines. Despite the fact that cogeneration has existed for a long time, it took half a century and the first so called ``oil crisis'' in the 1970's for societies to become aware of limited energy resources. Environmental groups gave cogeneration an additional boost in the 1980's. Additionally, governments in the Western European Nations attracted cogeneration investors by not only providing subsidies and tax breaks but also regulating electricity prices. Although there has been much growth in the cogeneration market in the past years, the industry has still not reached its peak in Europe. A variety of studies have shown that there is still significant growth potential in the future: WWF (World Wildlife Fund) published a study in 1996 suggesting a target of 330 Twh of generation will be produced through cogeneration by the year 2005, a tripling of current generation. Due to the EU's belief that cogeneration is an optimal form of generation, it has developed a cogeneration strategy. As part of this strategy, the EC is promoting cogeneration so that it accounts for 20% of all European generation by the year 2010. These factors would give a variety of companies such as equipment suppliers, investment companies, utilities, consultants and energy brokers a wide range of opportunities in Europe. Detailed information and some hints will be given as to how to participate in this fast growing industry. Ways to overcome obstacles in those markets will be shown as well as the pros and cons of different entry strategies.

    Cogeneration of heat and electricity is being considered by the South Dakota Soybean Processors for its facility in Volga, South Dakota, and a new facility to be located in Brewster, Minnesota. The Energy & Environmental Research Center has completed a feasibility study, with 40% funding provided from the U.S. Department of Energy's Jointly Sponsored Research Program to determine the potential application of firing biomass fuels combined with coal and comparative economics of natural gas-fired turbines. Various biomass fuels are available at each location. The most promising options based on availability are as follows. The economic impact of firing 25% biomass with coal can increase return on investment by 0.5 to 1.5 years when compared to firing natural gas. The results of the comparative economics suggest that a fluidized-bed cogeneration system will have the best economic performance. Installation for the Brewster site is recommended based on natural gas prices not dropping below a $4.00/MMBtu annual average delivered cost. Installation at the Volga site is only recommended if natural gas prices substantially increase to $5.00/MMBtu on average. A 1- to 2-year time frame will be needed for permitting and equipment procurement.

    The Woodside Landfill is owned by Livingston Parish, Louisiana and is operated under contract by Waste Management of Louisiana LLC. This public owner/private operator partnership is commonplace in the solid waste industry today. The landfill has been in operation since approximately 1988 and has a permitted capacity of approximately 41 million cubic yards. Based on an assumed in-place waste density of 0.94 ton per cubic yard, the landfill could have an expected design capacity of 39.3 million tons. The landfill does have an active landfill gas collection and control system (LFGCCS) in place because it meets the minimum thresholds for the New Source Performance Standards (NSPS). The initial LFGCS was installed prior to 2006 and subsequent phases were installed in 2007 and 2010. The Parish received a grant from the United States Department of Energy in 2009 to evaluate the potential for landfill gas recovery and utilization at the Woodside Landfill. This includes a technical and economic feasibility study of a project to install a landfill gas to energy (LFGTE) plant and to compare alternative technologies. The LFGTE plant can take the form of on-site electrical generation, a direct use/medium Btu option, or a high-Btu upgrade technology. The technical evaluation in Section 2 of this report concludes that landfill gas from the Woodside landfill is suitable for recovery and utilization. The financial evaluations in sections 3, 4, and 5 of this report provide financial estimates of the returns for various utilization technologies. The report concludes that the most economically viable project is the Electricity Generation option, subject to the Parish’s ability and willingness to allocate adequate cash for initial capital and/or to obtain debt financing. However, even this option does not present a solid return: by our estimates, there is a 19 year simple payback on the electricity generation option. All of the energy recovery options discussed in this report

    Methane (CH{sub 4}) diffuse emissions from Municipal Solid Waste (MSW) landfills represent one of the most important anthropogenic sources of greenhouse gas. CH{sub 4} is produced by anaerobic biodegradation of organic matter in landfilled MSW and constitutes a major component of landfill gas (LFG). Gas recovery is a suitable method to effectively control CH{sub 4} emissions from landfill sites and the quantification of CH{sub 4} emissions represents a good tool to evaluate the effectiveness of a gas recovery system in reducing LFG emissions. In particular, LFG emissions can indirectly be evaluated from mass balance equations between LFG production, recovery and oxidation in the landfill, as well as by a direct approach based on LFG emission measurements from the landfill surface. However, up to now few direct measurements of landfill CH{sub 4} diffuse emissions have been reported in the technical literature. In the present study, both modeling and direct emission measuring methodologies have been applied to the case study of Bellolampo landfill located in Palermo, Italy. The main aim of the present study was to evaluate CH{sub 4} diffuse emissions, based on direct measurements carried out with the flux accumulation chamber (static, non-stationary) method, as well as to obtain the CH{sub 4} contoured flux map of the landfill. Such emissions were compared with the estimate achieved by means of CH{sub 4} mass balance equations. The results showed that the emissions obtained by applying the flux chamber method are in good agreement with the ones derived by the application of the mass balance equation, and that the evaluated contoured flux maps represent a reliable tool to locate areas with abnormal emissions in order to optimize the gas recovery system efficiency.

    This study program is part of the DOE Integrated Industry Cogeneration Program to optimize, evaluate, and demonstrate cogeneration systems, with direct participation of the industries most affected. One objective is to characterize five major energy-intensive industries with respect to their energy-use profiles. The industries are: petroleum refining and related industries, textile mill products, paper and allied products, chemicals and allied products, and food and kindred products. Another objective is to select optimum cogeneration systems for site-specific reference case plants in terms of maximum energy savings subject to given return on investment hurdle rates. Analyses were made that define the range of optimal cogeneration systems for each reference-case plant considering technology applicability, economic factors, and energy savings by type of fuel. This study also provides guidance to other parts of the program through information developed with regard to component development requirements, institutional and regulatory barriers, as well as fuel use and environmental considerations.

    As a case study of the environmental feasibility of a major renovation to the University of Minnesota`s steam service facilities demonstrates, cogeneration is an efficient method of energy production and reduces area-wide air emissions by reducing the demand and production levels at less efficient facilities in the region. To acknowledge this benefit and encourage efficient production, {open_quotes}cogeneration credits{close_quotes} should be granted to energy producers as an offset to point-source emissions. This paper will identify the projected reduction in area-wide emissions for the University`s cogeneration project and alternatives and will demonstrate the method used for calculating those emissions. Although regulators have not yet fully accepted the validity of cogeneration credits, attitudes are starting to change, and we can only persuade regulators to encourage efficient production by discussing the issue now and by developing ways to make these ideas effective.

    Through the Urban Integrated Industrial Cogeneration Systems Analysis (UIICSA), the City of Chicago embarked upon an ambitious effort to identify the measure the overall industrial cogeneration market in the city and to evaluate in detail the most promising market opportunities. This report discusses the background of the work completed during Phase II of the UIICSA and presents the results of economic feasibility studies conducted for three potential cogeneration sites in Chicago. Phase II focused on the feasibility of cogeneration at the three most promising sites: the Stockyards and Calumet industrial areas, and the Ford City commercial/industrial complex. Each feasibility case study considered the energy load requirements of the existing facilities at the site and the potential for attracting and serving new growth in the area. Alternative fuels and technologies, and ownership and financing options were also incorporated into the case studies. Finally, site specific considerations such as development incentives, zoning and building code restrictions and environmental requirements were investigated.

  7. Energy conservation and electricity sector liberalization: Case-studies on the development of cogeneration, wind energy and demand-side management in the Netherlands, Denmark, Germany and the United Kingdom

    Slingerland, S.

    1998-07-01

    In this paper, the development of cogeneration, wind energy and demand-side management in the Netherlands, Denmark, Germany and the United Kingdom are compared. It is discussed to what extent these developments are determined by the liberalization process. Three key liberalization variables are identified: unbundling, privatization and introduction of competition. The analysis suggests that unbundling prior to introduction of full competition in generation is particularly successful in stimulating industrial cogeneration; simultaneous introduction of competition and unbundling mainly stimulates non-cogeneration gas-based capacity; and introduction of competition in itself is likely to impede the development of district-heating cogeneration. Furthermore, it is argued that development of wind energy and demand-side management are primarily dependent on the kind of support system set up by policy makers rather than on the liberalization process. Negative impacts of introduction of competition on integrated resource planning and commercial energy services could nevertheless be expected.

    A risk assessment process can assist in drawing a cost-effective compromise between economic and environmental costs, thereby assuring that the philosophy of 'sustainable development' is adhered to. Nowadays risk analysis is in wide use to effectively manage environmental issues. Risk assessment is also applied to other subjects including health and safety, food, finance, ecology and epidemiology. The literature review of environmental risk assessments in general and risk assessment approaches particularly regarding landfill disposal sites undertaken by the authors, reveals that an integrated risk assessment methodology for landfill gas, leachate or degraded waste does not exist. A range of knowledge gaps is discovered in the literature reviewed to date. From the perspective of landfill leachate, this paper identifies the extent to which various risk analysis aspects are absent in the existing approaches.

    Depending on the particular pollutants emitted, landfills may require service activities lasting from hundreds to thousands of years. Flexible tools allowing long-term predictions of emissions are of key importance to determine the nature and expected duration of maintenance and post-closure activities. A highly capable option represents predictions based on models and verified by experiments that are fast, flexible and allow for the comparison of various possible operation scenarios in order to find the most appropriate one. The intention of the presented work was to develop a experimentally verified multi-dimensional predictive model capable of quantifying and estimating processes taking place in landfill sites where coupled process description allows precise time and space resolution. This constitutive 2-dimensional model is based on the macromechanical theory of porous media (TPM) for a saturated thermo-elastic porous body. The model was used to simulate simultaneously occurring processes: organic phase transition, gas emissions, heat transport, and settlement behavior on a long time scale for municipal solid waste deposited in a landfill. The relationships between the properties (composition, pore structure) of a landfill and the conversion and multi-phase transport phenomena inside it were experimentally determined. In this paper, we present both the theoretical background of the model and the results of the simulations at one single point as well as in a vertical landfill cross section.

  12. LANDFILL OPERATION FOR CARBON SEQUESTRATION AND MAXIMUM METHANE EMISSION CONTROL

    The work described in this report, to demonstrate and advance this technology, has used two demonstration-scale cells of size (8000 metric tons [tonnes]), sufficient to replicate many heat and compaction characteristics of larger ''full-scale'' landfills. An enhanced demonstration cell has received moisture supplementation to field capacity. This is the maximum moisture waste can hold while still limiting liquid drainage rate to minimal and safely manageable levels. The enhanced landfill module was compared to a parallel control landfill module receiving no moisture additions. Gas recovery has continued for a period of over 4 years. It is quite encouraging that the enhanced cell methane recovery has been close to 10-fold that experienced with conventional landfills. This is the highest methane recovery rate per unit waste, and thus progress toward stabilization, documented anywhere for such a large waste mass. This high recovery rate is attributed to moisture, and elevated temperature attained inexpensively during startup. Economic analyses performed under Phase I of this NETL contract indicate ''greenhouse cost effectiveness'' to be excellent. Other benefits include substantial waste volume loss (over 30%) which translates to extended landfill life. Other environmental benefits include rapidly improved quality and stabilization (lowered pollutant levels) in liquid leachate which drains from the waste.

  14. Modified biochemical methane potential (BMP) assays to assess biodegradation potential of landfilled refuse

    1989-01-01

    Modified Biochemical Methane Potential (BMP) assays were used to assess biogas production potential of solid landfill samples. In landfill samples with visible soil content, moisture addition alone was generally as effective at stimulating biogas production as the addition of a comprehensive nutrient media. In a variety of samples from humid and semiarid landfills, addition of an aqueous nutrient media was the most effective stimulant for biogas production; however, moisture addition was almost as effective for most samples, suggesting that water addition would be the most cost-effective field approach. Onset of methanogenesis was slower in fresh refuse samples (even when inoculated with anaerobic digester sludge) than in landfill samples, indicating that the soil into which materials are landfilled is a major source of microorganisms. High volatile solids loading in fresh refuse and landfill assays retarded methanogenesis. A comparison of anaerobic and aerobic sample handling techniques showed no significant differences with regard to onset of methanogenesis and total gas production. The technique shows initial promise with regard to replication and reproducibility of results and could be a meaningful addition to landfill site evaluations where commercial gas recovery is anticipated. The BMP technique could also be adapted to assess anaerobic biodegradability of other solid waste materials for conventional anaerobic digestion applications. 9 refs., 6 figs., 2 tabs.

    1993-03-01

    This article describes a means for industrial, institutional, and commercial energy users to reduce their costs through increased energy efficiency while providing resource management and environmental benefits. There is a significant opportunity for industrial, institutional, and commercial energy users to reduce their costs through the development of internal-use cogeneration systems. These cost reductions are the direct result of increased energy efficiency, providing both resource management and environmental benefits. While internal-use cogeneration may be cost effective, the development of the full potential for this option is hindered by electric utility resistance and counter-marketing and by the neglect of many state regulatory bodies. If the end user is to reap the benefits of this option, then he must develop an understanding of the technology and the developmental process, formulate reasonable expectations as to the benefits of cogeneration, and step forward to provide the initiative required to obtain those benefits. Similarly, the cogeneration industry must recognize the unique developmental issues that arise within the context of small displacement projects and develop the required engineering, financing, construction, and operating infrastructure. Finally, regulators must allow internal-use cogeneration to achieve its full, free-market potential.

    Economic considerations constitute the major factor in the decision to build a cogeneration plant and to its eventual design - topics which have been the focus of many studies and papers. These economic concerns continue when the plant is built and on-line, thus plant operation must be geared to provide the customers` demand in the most economically effective manner possible. Unfortunately, the complexity of and high degree of interaction between the disparate components of a cogeneration plant oftentimes, make it difficult to conceptualize the plant configuration required to maximize plant economic performance for a given demand, Indeed, actions taken to increase the thermal performance of individual plant components can actually decrease the overall economic effectiveness of the plant as a whole in the context of converting fuels to sendouts. What is needed, then, is a way to meld the performance of individual plant components into a total plant performance index that accurately measures the economic effectiveness of the plant. This paper details such a method developed by the Cogeneration Management Company to accomplish the performance evaluation of its Medical Area Total Energy Plant which supplies electricity, steam, and chilled water to the Longwood. Medical Area in Boston, This method - which is easily adapted to a variety of cogeneration designs - addresses the aforementioned complexities in the assessing of a cogeneration plant`s effectiveness and results in simple-to-understand plant performance quantifications which have proved to be of great utility in ensuring the economically sound operation of MATEP.

    A market study indicates a significant market potential for small commercial cogeneration (50-500 kW) over the next 20 years. The potential exists for 1500 installations per year, 80% of those would be a system composed of Engine-Generator and Heat Recovery Unit with the remainder requiring the addition of an Absorption Chiller. A preliminary design for an advanced Heat Recovery Unit (HRU) was completed. The unit incorporates the capability of supplementary firing of the exhaust gas from the new generation of natural gas fired lean burn reciprocating engines being developed for cogeneration applications. This gives the Heat Recovery Unit greater flexibility in following the thermal load requirements of the building. An applications and design criteria analysis indicated that this was a significant feature for the HRU as it can replace a standard auxiliary boiler thus affording significant savings to the building owner. A design for an advanced absorption chiller was reached which is 15% lower in cost yet 9% more efficient than current off-the-shelf units. A packaged cogeneration system cost and design analysis indicates that a nominal 254 kW cogeneration system incorporating advanced components and packaging concepts can achieve a selling price of less than $880/kW and $700/kW with and without an absorption chiller.

    A thermodynamic study of an 88.4 MW cogeneration plant located in the United States is presented in this paper. The feedstock for this actual plant is culm, the waste left from anthracite coal mining. Before combustion in circulating fluidized bed boilers, the usable carbon within the culm is separated from the indigenous rock. The rock and ash waste from the combustion process fill adjacent land previously scared by strip mining. Trees and grass are planted in these areas as part of a land reclamation program. Analyses based on the first and second laws of thermodynamics using actual operating data are first presented to acquaint the reader with the plant's components and operation. Using emission and other relevant environmental data from the plant, all externalities study is outlined that estimates the plant's effect on the local population. The results show that the plant's cycle performs with a coefficient of utilization of 29% and all approximate exergetic efficiency of 34.5%. In order to increase these values, recommended improvements to the plant are noted. In addition, the externality costs associated with the estimated SO{sub 2} and NOx discharge from the culm fed plant are lower (85-95%) than those associated with a similarly sized coal fed plant. The plant's cycle efficiencies are lower than those associated with more modern technologies; such as all integrated gas turbine combined cycle. However, given the abundant, inexpensive supply of feedstock located adjacent to the plant and the environmental benefit of removing culm banks, the plant's existing operation is unique from an economical and environmental viewpoint.

    Cogeneration is now accepted as a cost-effective and environmentally friendly means of meeting some of a building`s heating and power needs. Cogeneration plants have been installed in many buildings throughout the United Kingdom. Because of commercial pressures, building owners and cogeneration companies are keen to reduce the time and money involved in sizing units, and a decision support tool has been developed to aid the engineer in selecting the unit size. An initial assessment of the sizing can be made with only knowledge of the building`s type, size, and location, which enables the model to be used in new build situations. For an existing building, the accuracy of the predictions can then be progressively improved by providing more information about the building`s energy use, enabling the optimum unit to be identified. This paper briefly describes the model and demonstrates its use through an example feasibility study.

    Cogeneration, also known as combined heat and power (CHP), is the combined sequential generation of electricity and thermal or electric energy. The technology has been known essentially since the first commercial generation of electricity as a high efficiency technology option. After a period of decline, its use increased significantly during the 1980s and it is receiving renewed interest lately as a means of increasing efficiency and reducing emissions of air pollutants including carbon emissions. New and developing technology options have added to this potential. Forecasts of future growth and efforts to stimulate cogeneration need to take into account the history of the technology, the factors that have driven it in the past, and factors which could stimulate or retard future growth. This paper reviews and analyzes these factors and looks toward the future potential for cogeneration.

    1996-01-01

    As a key part of DOE`s and industry`s R&D efforts to improve the efficiency, cost, and emissions of power generation, a prototype High Performance Steam System (HPSS) has been designed, built, and demonstrated. The world`s highest temperature ASME Section I coded power plant successfully completed over 100 hours of development tests at 1500{degrees}F and 1500 psig on a 56,000 pound per hour steam generator, control valve and topping turbine at an output power of 5500 hp. This development advances the HPSS to 400{degrees}F higher steam temperature than the current best technology being installed around the world. Higher cycle temperatures produce higher conversion efficiencies and since steam is used to produce the large majority of the world`s power, the authors expect HPSS developments will have a major impact on electric power production and cogeneration in the twenty-first century. Coal fueled steam plants now produce the majority of the United States electric power. Cogeneration and reduced costs and availability of natural gas have now made gas turbines using Heat Recovery Steam Generators (HRSG`s) and combined cycles for cogeneration and power generation the lowest cost producer of electric power in the United States. These gas fueled combined cycles also have major benefits in reducing emissions while reducing the cost of electricity. Development of HPSS technology can significantly improve the efficiency of cogeneration, steam plants, and combined cycles. Figure 2 is a TS diagram that shows the HPSS has twice the energy available from each pound of steam when expanding from 1500{degrees}F and 1500 psia to 165 psia (150 psig, a common cogeneration process steam pressure). This report describes the prototype component and system design, and results of the 100-hour laboratory tests. The next phase of the program consists of building up the steam turbine into a generator set, and installing the power plant at an industrial site for extended operation.

    General Electric's method of steam turbine performance was used with pure electrical and with cogeneration power plants at various flow rates. Comparisons were made for two cases: (1) the same amount of heat is added to each boiler and the amount of electrical power generated is compared; and (2) when each plant should produce the same amount of electric power and the amount of heat added to each boiler is compared. Cogeneration is energetically more efficient than pure electrical plant. Correlations for the dependence of heat rate, power generated, heat added to throttle flow ratio were obtained from this work.

    This report covers the activity during the period from 2 June 1991 to 1 June 1992. The major areas of work include: the combustor sub-scale and full size testing, cleanup, coal fuel specification and processing, the Hot End Simulation rig and design of the engine parts required for use with the coal-fueled combustor island. To date Solar has demonstrated: Stable and efficient combustion burning coal-water mixtures using the Two Stage Slagging Combustor; Molten slag removal of over 97% using the slagging primary and the particulate removal impact separator; and on-site preparation of CWM is feasible. During the past year the following tasks were completed: The feasibility of on-site CWM preparation was demonstrated on the subscale TSSC. A water-cooled impactor was evaluated on the subscale TSSC; three tests were completed on the full size TSSC, the last one incorporating the PRIS; a total of 27 hours of operation on CWM at design temperature were accumulated using candle filters supplied by Refraction through Industrial Pump Filter; a target fuel specification was established and a fuel cost model developed which can identify sensitivities of specification parameters; analyses of the effects of slag on refractory materials were conducted; and modifications continued on the Hot End Simulation Rig to allow extended test times.

  12. Tomorrow`s energy today for cities and counties: Cogeneration powers up cost-competitive energy

    SciTech Connect (OSTI)

    1995-11-01

    Cities and counties build many multi-million dollar facilities, and supplying energy to run these facilities is a long-term obligation for a community. Cogeneration offers local governments an opportunity to reduce the cost of providing electricity, heating, and cooling to their buildings. Sometimes cogeneration is combined with district heating and cooling systems. This kind of cogeneration results in system efficiencies as high as 70%--about twice the efficiency of a conventional power plant that produces only electricity! The article describes cogeneration combined with district cooling in Trenton, NJ, and cogeneration on a small scale in San Jose, California.

    The implementation of landfill gas to energy (LFGTE) projects has greatly assisted in reducing the greenhouse gases and air pollutants, leading to an improved local air quality and reduced health risks. The majority of cities in developing countries still dispose of their municipal waste in uncontrolled 'open dumps.' Municipal solid waste landfill construction practices and operating procedures in these countries pose a challenge to implementation of LFGTE projects because of concern about damage to the gas collection infrastructure (horizontal headers and vertical wells) caused by minor, relatively shallow slumps and slides within the waste mass. While major slope failures can and have occurred, such failures in most cases have been shown to involve contributory factors or triggers such as high pore pressures, weak foundation soil or failure along weak geosynthetic interfaces. Many researchers who have studied waste mechanics propose that the shear strength of municipal waste is sufficient such that major deep-seated catastrophic failures under most circumstances require such contributory factors. Obviously, evaluation of such potential major failures requires expert analysis by geotechnical specialists with detailed site-specific information regarding foundation soils, interface shearing resistances and pore pressures both within the waste and in clayey barrier layers or foundation soils. The objective of this paper is to evaluate the potential use of very simple stability analyses which can be used to study the potential for slumps and slides within the waste mass and which may represent a significant constraint on construction and development of the landfill, on reclamation and closure and on the feasibility of a LFGTE project. The stability analyses rely on site-specific but simple estimates of the unit weight of waste and the pore pressure conditions and use 'generic' published shear strength envelopes for municipal waste.

    This article describes the first major privatization effort to be completed at John F. Kennedy International Airport. The airport owner and operator, the Port Authority of New York and New Jersey, decided to seek private sector involvement in a capital-intensive project to expand and upgrade the airport`s heating and air conditioning facilities and construct a new cogeneration plant. Kennedy International Airport Cogeneration (KIAC) Partners, a partnership between Gas Energy Incorporated of New York and Community Energy Alternatives of New Jersey, was selected to develop an energy center to supply electricity and hot and chilled water to meet the airport`s growing energy demand. Construction of a 110 MW cogeneration plant, 7,000 tons of chilled water equipment, and 30,000 feet of hot water delivery piping started immediately. JFK Airport`s critical international position called for this substantial project to be developed almost invisibly; no interruption in heating and air conditioning service and no interference in the airport`s active operations could be tolerated. Commercial operation was achieved in February 1995.

  15. Fluxes of methane between landfills and the atmosphere: Natural and engineered controls

    Field measurement of landfill methane emissions indicates natural variability spanning more than 2 seven orders of magnitude, from approximately 0.0004 to more than 4000 g m{sub -2} day{sup -1}. This wide range reflects net emissions resulting from production (methanogenesis), consumption (methanotrophic oxidation), and gaseous transport processes. The determination of an {open_quotes}average{close_quotes} emission rate for a given field site requires sampling designs and statistical techniques which consider spatial and temporal variability. Moreover, particularly at sites with pumped gas recovery systems, it is possible for methanotrophic microorganisms in aerated cover soils to oxidize all of the methane from landfill sources below and, additionally, to oxidize methane diffusing into cover soils from atmospheric sources above. In such cases, a reversed soil gas concentration gradient is observed in shallow cover soils, indicating bidirectional diffusional transport to the depth of optimum methane oxidation. Rates of landfill methane oxidation from field and laboratory incubation studies range up to 166 g m{sup -2} day{sup -1} among the highest for any natural setting, providing an effective natural control on net emissions. Estimates of worldwide landfill methane emissions to the atmosphere have ranged from 9 to 70 Tg yr{sup -1}, differing mainly in assumed methane yields from estimated quantities of landfilled refuse. At highly controlled landfill sites in developed countries, landfill methane is often collected via vertical wells or horizontal collectors. Recovery of landfill methane through engineered systems can provide both environmental and energy benefits by mitigating subsurface migration, reducing surface emissions, and providing an alternative energy resource for industrial boiler use, on-site electrical generation, or upgrading to a substitute natural gas.

    1990-10-01

    The Defense Appropriations Act of 1986 requires the Department of Defense to use an additional 1,600,000 tons/year of coal at their US facilities by 1995 and also states that the most economical fuel should be used at each facility. In a previous study of Air Force heating plants burning gas or oil, Oak Ridge National Laboratory found that only a small fraction of this target 1,600,000 tons/year could be achieved by converting the plants where coal is economically viable. To identify projects that would use greater amounts of coal, the economic benefits of installing coal-fired cogeneration plants at 7 candidate Air Force bases were examined in this study. A life-cycle cost analysis was performed that included two types of financing (Air Force and private) and three levels of energy escalation for a total of six economic scenarios. Hill, McGuire, and Plattsburgh Air Force Bases were identified as the facilities with the best potential for coal-fired cogeneration, but the actual cost savings will depend strongly on how the projects are financed and to a lesser extent on future energy escalation rates. 10 refs., 11 figs., 27 tabs.

    In the past, landfills or {open_quotes}dumps{close_quotes} were not highly regulated and typically did not require a detailed engineering design. However, landfills are no longer just holes in the ground, and landfill closures entail more than just spreading some dirt on top of piles of garbage. Today landfill design is a highly regulated, complex design effort that integrates soils and geosynthetics into systems aimed at providing long-term protection for the environment and surrounding communities. Integrating these complex design systems into the available landscape and exising landfill configuration often requires the designer go beyond the {open_quotes}typical{close_quotes} landfill and landfill closure design to satisfy regulations and provide cost-effective solutions.

    Highlights: Limited information in the literature on the use of GPR to measure in situ water content in a landfill. Developed GPR method allows measurement of in situ water content in a landfill. Developed GPR method is appealing to waste management professionals operating landfills. - Abstract: Landfill gas (LFG) receives a great deal of attention due to both negative and positive environmental impacts, global warming and a green energy source, respectively. However, predicting the quantity of LFG generated at a given landfill, whether active or closed is difficult due to the heterogeneities present in waste, and the lack of accurate in situ waste parameters like water content. Accordingly, ground penetrating radar (GPR) was evaluated as a tool for estimating in situ water content. Due to the large degree of subsurface heterogeneity and the electrically conductive clay cap covering landfills, both of which affect the transmission of the electromagnetic pulses, there is much scepticism concerning the use of GPR to quantify in situ water content within a municipal landfill. Two landfills were studied. The first landfill was used to develop the measurement protocols, while the second landfill provided a means of confirming these protocols. GPR measurements were initially completed using the surface GPR approach, but the lack of success led to the use of borehole (BH) GPR. Both zero offset profiling (ZOP) and multiple offset gathers (MOG) modes were tried, with the results indicating that BH GPR using the ZOP mode is the most simple and efficient method to measure in situ water content. The best results were obtained at a separation distance of 2 m, where higher the water content, smaller the effective separation distance. However, an increase in water content did appear to increase the accuracy of the GPR measurements. For the effective separation distance of 2 m at both landfills, the difference between GPR and lab measured water contents were reasonable at 33

    Highlights: • ‘Zero waste’ initiatives never consider risks, side effects or experience of achieved low levels of landfill. • This paper provides insight into what works and what not. • Where strong gradients in regulations and tax occur between countries, waste will find its way to landfills across borders. • Strong landfill reduction can create a fierce competition over the remaining waste to be landfilled resulting in losses. • At some point a public organisation should take responsibility for the operation of a ‘safety net’ in waste management. - Abstract: Modern waste legislation aims at resource efficiency and landfill reduction. This paper analyses more than 20 years of landfill reduction in the Netherlands. The combination of landfill regulations, landfill tax and landfill bans resulted in the desired landfill reduction, but also had negative effects. A fierce competition developed over the remaining waste to be landfilled. In 2013 the Dutch landfill industry generated €40 million of annual revenue, had €58 million annual costs and therefore incurred an annual loss of €18 million. It is not an attractive option to prematurely end business. There is a risk that Dutch landfill operators will not be able to fulfil the financial obligations for closure and aftercare. Contrary to the polluter pays principle the burden may end up with society. EU regulations prohibiting export of waste for disposal are in place. Strong differentials in landfill tax rate between nations have nevertheless resulted in transboundary shipment of waste and in non-compliance with the self-sufficiency and proximity principles. During the transformation from a disposal society to a recycling society, it is important to carefully plan required capacity and to guide the reorganisation of the landfill sector. At some point, it is no longer profitable to provide landfill services. It may be necessary for public organisations or the state to take responsibility for the

  2. Differences in volatile methyl siloxane (VMS) profiles in biogas from landfills and anaerobic digesters and energetics of VMS transformations

    Tansel, Berrin Surita, Sharon C.

    2014-11-15

    Highlights: • In the digester gas, D4 and D5 comprised the 62% and 27% if siloxanes, respectively. • In landfill gas, the bulk of siloxanes were TMSOH (58%) followed by D4 (17%). • Methane utilization may be a possible mechanism for TMSOH formation in the landfills. • The geometric configurations of D4 and D5 molecules make them very stable. - Abstract: The objectives of this study were to compare the types and levels of volatile methyl siloxanes (VMS) present in biogas generated in the anaerobic digesters and landfills, evaluate the energetics of siloxane transformations under anaerobic conditions, compare the conditions in anaerobic digesters and municipal solid waste (MSW) landfills which result in differences in siloxane compositions. Biogas samples were collected at the South District Wastewater Treatment Plant and South Dade Landfill in Miami, Florida. In the digester gas, D4 and D5 comprised the bulk of total siloxanes (62% and 27%, respectively) whereas in the landfill gas, the bulk of siloxanes were trimethylsilanol (TMSOH) (58%) followed by D4 (17%). Presence of high levels of TMSOH in the landfill gas indicates that methane utilization may be a possible reaction mechanism for TMSOH formation. The free energy change for transformation of D5 and D4 to TMSOH either by hydrogen or methane utilization are thermodynamically favorable. Either hydrogen or methane should be present at relatively high concentrations for TMSOH formation which explains the high levels present in the landfill gas. The high bond energy and bond distance of the Si–O bond, in view of the atomic sizes of Si and O atoms, indicate that Si atoms can provide a barrier, making it difficult to break the Si–O bonds especially for molecules with specific geometric configurations such as D4 and D5 where oxygen atoms are positioned inside the frame formed by the large Si atoms which are surrounded by the methyl groups.

    Post-closure care (PCC) activities at landfills include cap maintenance; water quality monitoring; maintenance and monitoring of the gas collection/control system, leachate collection system, groundwater monitoring wells, and surface water management system; and general site maintenance. The objective of this study was to develop an integrated data and knowledge based decision making tool for preliminary estimation of PCC needs at closed landfills. To develop the decision making tool, 11 categories of parameters were identified as critical areas which could affect future PCC needs. Each category was further analyzed by detailed questions which could be answered with limited data and knowledge about the site, its history, location, and site specific characteristics. Depending on the existing knowledge base, a score was assigned to each question (on a scale 1-10, as 1 being the best and 10 being the worst). Each category was also assigned a weight based on its relative importance on the site conditions and PCC needs. The overall landfill score was obtained from the total weighted sum attained. Based on the overall score, landfill conditions could be categorized as critical, acceptable, or good. Critical condition indicates that the landfill may be a threat to the human health and the environment and necessary steps should be taken. Acceptable condition indicates that the landfill is currently stable and the monitoring should be continued. Good condition indicates that the landfill is stable and the monitoring activities can be reduced in the future. The knowledge base algorithm was applied to two case study landfills for preliminary assessment of PCC performance.

    Highlights: Black-Right-Pointing-Pointer Residential waste diversion initiatives are more successful with organic waste. Black-Right-Pointing-Pointer Using a incineration to manage part of the waste is better environmentally. Black-Right-Pointing-Pointer Incineration leads to more power plant emission offsets. Black-Right-Pointing-Pointer Landfilling all of the waste would be preferred financially. - Abstract: This study evaluates the environmental performance and discounted costs of the incineration and landfilling of municipal solid waste that is ready for the final disposal while accounting for existing waste diversion initiatives, using the life cycle assessment (LCA) methodology. Parameters such as changing waste generation quantities, diversion rates and waste composition were also considered. Two scenarios were assessed in this study on how to treat the waste that remains after diversion. The first scenario is the status quo, where the entire residual waste was landfilled whereas in the second scenario approximately 50% of the residual waste was incinerated while the remainder is landfilled. Electricity was produced in each scenario. Data from the City of Toronto was used to undertake this study. Results showed that the waste diversion initiatives were more effective in reducing the organic portion of the waste, in turn, reducing the net electricity production of the landfill while increasing the net electricity production of the incinerator. Therefore, the scenario that incorporated incineration performed better environmentally and contributed overall to a significant reduction in greenhouse gas emissions because of the displacement of power plant emissions; however, at a noticeably higher cost. Although landfilling proves to be the better financial option, it is for the shorter term. The landfill option would require the need of a replacement landfill much sooner. The financial and environmental effects of this expenditure have yet to be considered.

    Wiltsee, G.

    1993-12-01

    What is cogeneration and how does it reduce costs? Cogeneration is the production of power -- and useful heat -- from the same fuel. In a typical biomass-fueled cogeneration plant, a steam turbine drives a generator, producing electricity. The plant uses steam from the turbine for heating, drying, or other uses. The benefits of cogeneration can mostly easily be seen through actual samples. For example, cogeneration fits well with the operation of sawmills. Sawmills can produce more steam from their waste wood than they need for drying lumber. Wood waste is a disposal problem unless the sawmill converts it to energy. The case studies in Section 8 illustrate some pluses and minuses of cogeneration. The electricity from the cogeneration plant can do more than meet the in-house requirements of the mill or manufacturing plant. PURPA -- the Public Utilities Regulatory Policies Act of 1978 -- allows a cogenerator to sell power to a utility and make money on the excess power it produces. It requires the utility to buy the power at a fair price -- the utility`s {open_quotes}avoided cost.{close_quotes} This can help make operation of a cogeneration plant practical.

    The Lantana Sanitary Landfill (LSL) is located in central Palm Beach County, Florida. The history of this landfill is a case study of the changes in environmental law, demography, solid waste management, hydrogeology, and public opinion in south Florida in the last 30 years. In 1983 Palm Beach County transferred ownership of the LSL to the Palm Beach County Solid Waste Authority (SWA). Environmental regulation enacted by Florida in the mid 1980`s resulted in negotiations to close the LSL. Closure was completed in 1988 utilizing a synthetic top liner, a landfill gas extraction/flare system, and a stormwater management system. In 1990 a groundwater mitigation system was installed to remediate the eastern plume. Closure of the LSL, extension of municipal water to local residents, and extensive public education by the SWA all served to answer most of the complaints of the local residents. In 1996 the LSL fell under a new series of air regulations and was required to apply for a Title V permit.

    The results of a study investigating solar cogeneration in conjunction with a flash furnace copper smelting operation in southwest New Mexico are presented. Results include a discussion of the overall system configuration with particular emphasis on system design, operation and control. Preliminary findings of the study indicate the potential for an increase in copper production of up to 90 percent due to the higher oxygen content of ambient air relative to the currently combusted air source. Projected capital costs estimates for the facility coupled with appropriate schedule and economic assumptions indicate that a return on investment in excess of 30 percent is achievable.

    An experimental observation of spatiotemporal evolution of dust density waves (DDWs) in cogenerated dusty plasma in the presence of modified field induced by glass plate is reported. Various DDWs, such as vertical, oblique, and stationary, were detected simultaneously for the first time. Evolution of spatiotemporal complexity like bifurcation in propagating wavefronts is also observed. As dust concentration reaches extremely high value, the DDW collapses. Also, the oblique and nonpropagating mode vanishes when we increase the number of glass plates, while dust particles were trapped above each glass plates showing only vertical DDWs.

    An integrated risk assessment study has been performed in an area within 5 km from a landfill that accepts non hazardous waste. The risk assessment was based on measured emissions and maximum chronic population exposure, for both children and adults, to contaminated air, some foods and soil. The toxic effects assessed were limited to the main known carcinogenic compounds emitted from landfills coming both from landfill gas torch combustion (e.g., dioxins, furans and polycyclic aromatic hydrocarbons, PAHs) and from diffusive emissions (vinyl chloride monomer, VCM). Risk assessment has been performed both for carcinogenic and non-carcinogenic effects. Results indicate that cancer and non-cancer effects risk (hazard index, HI) are largely below the values accepted from the main international agencies (e.g., WHO, US EPA) and national legislation ( and ).

    The Delaware Solid Waste Authority's Northern Solid Waste Management Center is located outside of Wilmington Delaware at Cherry Island, a former dredge disposal site. Dredge spoils, of very low permeability, range in depths up to 30 m (100 feet) which form a natural liner and the foundation for the 140 ha (350-acre) municipal solid waste landfill. The soils beneath the landfill have been extensively instrumented to measure pore pressure, settlement and deflections, using inclinometer casings, standpipe piezometers, vibrating wire piezometers, pneumatic piezometers, settlement plates, liquid settlement gages, total pressure cells and thermistors. The nature of the existing waste and anticipated settlements (up to 6 m (19 feet)) have required some unique installation details. The instrumentation data has been integral in planning the landfilling sequence to maintain perimeter slope stability and has provided key geotechnical parameters needed for operation and construction of the landfill. The performance of the instrumentation and monitoring results are discussed.

Black-Right-Pointing-Pointer An explanatory approach in connection with the inconsistencies is provided. - Abstract: The creation of sustainable landfills is a fundamental goal in waste management worldwide. In this connection landfill aeration contributes towards an accelerated, controlled and sustainable conversion of conventional anaerobic landfills into a biological stabilized state associated with a minimised emission potential. The technology has been successfully applied to landfills in Europe, North America and Asia, following different strategies depending on the geographical region, the specific legislation and the available financial resources. Furthermore, methodologies for the incorporation of landfill aeration into the carbon trade mechanisms have been developed in recent years. This manuscript gives an overview on existing concepts for landfill aeration; their application ranges and specifications. For all of the described concepts examples from different countries worldwide are provided, including details regarding their potentials and limitations. Some of the most important findings from these aeration projects are summarised and future research needs have been identified. It becomes apparent that there is a great demand for a systematisation of the available results and implications in order to further develop and optimise this very promising technology. The IWWG (International Waste Working Group) Task Group 'Landfill Aeration' contributes towards the achievement of this goal.

    Highlights: ► The isotopic signature of δ{sup 13}C-DIC of leachates is linked to the reactivity of MSW. ► Isotopic signatures of leachates depend on aerobic/anaerobic conditions in landfills. ► In situ aeration of landfills can be monitored by isotope analysis in leachate. ► The isotopic analysis of leachates can be used for assessing the stability of MSW. ► δ{sup 13}C-DIC of leachates helps to define the duration of landfill aftercare. - Abstract: Stable isotopic signatures of landfill leachates are influenced by processes within municipal solid waste (MSW) landfills mainly depending on the aerobic/anaerobic phase of the landfill. We investigated the isotopic signatures of δ{sup 13}C, δ{sup 2}H and δ{sup 18}O of different leachates from lab-scale experiments, lysimeter experiments and a landfill under in situ aeration. In the laboratory, columns filled with MSW of different age and reactivity were percolated under aerobic and anaerobic conditions. In landfill simulation reactors, waste of a 25 year old landfill was kept under aerobic and anaerobic conditions. The lysimeter facility was filled with mechanically shredded fresh waste. After starting of the methane production the waste in the lysimeter containments was aerated in situ. Leachate and gas composition were monitored continuously. In addition the seepage water of an old landfill was collected and analysed periodically before and during an in situ aeration. We found significant differences in the δ{sup 13}C-value of the dissolved inorganic carbon (δ{sup 13}C-DIC) of the leachate between aerobic and anaerobic waste material. During aerobic degradation, the signature of δ{sup 13}C-DIC was mainly dependent on the isotopic composition of the organic matter in the waste, resulting in a δ{sup 13}C-DIC of −20‰ to −25‰. The production of methane under anaerobic conditions caused an increase in δ{sup 13}C-DIC up to values of +10‰ and higher depending on the actual reactivity of the MSW

    1998-10-31

    This report describes a two-phase energy project currently contemplated for joint implementation at the Victorias Milling Company, a large sugar mill and refinery on the island of Negros in the Visayas region of the Philippines. The Energy Efficiency (EE) phase is expected to reduce of eliminate VMC`s fossil fuel consumption, which will have a direct and substantial impact on carbon emissions. Phase I is an EE project which involves the installation of equipment to reduce steam and electricity demand in the factories. Phase II, will involve retrofitting and increasing the capacity of the steam and power generation systems, and selling power to the grid. By increasing efficiency and output, the cogeneration project will allow the factory to use only bagasse sugar cane fiber waste as fuel for energy needs. The cogeneration project will also eliminate VMC`s electricity purchases and supply additional power for the island, which will offset generation capacity expansion on the island and the Visayas region.

    The U.S. Environmental Protection Agency (EPA), in accordance with the RE-Powering America's Land initiative, selected the Commonwealth of Puerto Rico for a feasibility study of m0treAlables on several brownfield sites. The EPA defines a brownfield as 'a property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant.' All of the brownfields in this study are landfill sites. Citizens of Puerto Rico, city planners, and site managers are interested in redevelopment uses for landfills in Puerto Rico, which are particularly well suited for solar photovoltaic (PV) installation. The purpose of this report is to assess the landfills with the highest potential for possible solar PV installation and estimate cost, performance, and site impacts of three different PV options: crystalline silicon (fixed-tilt), crystalline silicon (single-axis tracking), and thin film (fixed-tilt). Each option represents a standalone system that can be sized to use an entire available site area. In addition, the report outlines financing options that could assist in the implementation of a system. The feasibility of PV systems installed on landfills is highly impacted by the available area for an array, solar resource, operating status, landfill cap status, distance to transmission lines, and distance to major roads. All of the landfills in Puerto Rico were screened according to these criteria in order to determine the sites with the greatest potential. Eight landfills were chosen for site visits based on the screening criteria and location. Because of time constraints and the fact that Puerto Rico is a relatively large island, the eight landfills for this visit were all located in the eastern half of the island. The findings from this report can be applied to landfills in the western half of the island. The economics of a potential PV system on landfills in Puerto Rico depend greatly on the

    The author describes the development of the cogeneration system at the University of Colorado at Boulder campus, which was brought on line in 1992. The author reviews the history of power and utilities services for the campus. Prior to 1932, the campus maintained a coal fired cogeneration facility. In the 1980`s, evaluation of existing systems on campus, and changes in regulations for public utilities, prompted the campus to implement a new cogeneration facility, housed in the building originally used for this purpose. This facility allows the university to control this aspect of its needs, provides cheaper utilities, and allows the university to be directly involved in energy conservation.

    A numerical model, TOUGH2, was selected for describing liquid- and gas-phase flow in the unsaturated tuff underlying the TA-73 landfill. The model was selected primarily for its ability to simulate the significant mechanisms that may affect transport of contaminants through the vadose zone at the TA-73 landfill, including non-isothermal flow through fractured media. TOUGH2 is the best documented, verified, and validated model capable of performing the required simulations. The sensitivity analyses that were performed and describes in this report identified the input parameters that the selected numerical model is most sensitive to. The input parameters analyzed were saturated hydraulic conductivity, van Genuchten {alpha} and n, residual and saturated moisture contents, infiltration rate, fracture spacing and permeability, atmospheric pressure, and temperature. The sensitivity analyses were performed using a model grid that was designed to incorporate the regions in the landfill vicinity where contaminant transport is likely to occur and where the physical processes affecting flow and transport are the most dynamic. The sensitivity analyses performed suggest that the model is quite sensitive to a number of input parameters, including saturated hydraulic conductivity, the van Genuchten parameters {alpha} and n (for both the tuff matrix and fractures), fracture density and aperture, and atmospheric pressure. The results indicate that additional site-specific hydraulic properties and fracture data should be obtained before attempting to perform predictive, numerical simulations of gas- and liquid-phase flow beneath the landfill.

    Several geophysical methods were used over portions of the Gracelawn landfill, in Auburn, Maine to determine the surface boundaries and subsurface structure of this closed landfill, and to determine the landfill's effects on groundwater quality. The landfill was originally a sand and gravel pit excavated in the 1950's and early 1960's, and was used as a landfill from 1964--1977. The site is unlined, has a clay cap, and has been graded and developed as a baseball park. Two seismic refraction lines were performed to obtain a minimum depth to bedrock of 80 m. Seismic velocities of methane gas-saturated trash ranged from 250 to 340 m/s, and sand velocities are approximately 800 m/s. Two electrical resistivity Wenner surveys over the trash yielded the depth to saturated material and thickness of the trash layers. Resistivity values for dry refuse ranged from 1,000-2,000 [Omega]*m. A third electrical resistivity survey yielded the thickness of unsaturated and saturated sands bordering the landfill. Dry sands were found to have a resistivity of 1,000 [Omega]*m, and saturated sands a resistivity of 500 [Omega]*m. Gravity and magnetic survey grids across the site revealed anomalies which were mapped to illustrate the irregular morphology of the buried trash as well as its surface boundaries. Residual magnetic anomalies are on the order of 2,000 nT. Residual gravity anomalies are up to 5 mGal. Groundwater elevations determined by the geophysical survey, combined with a survey of existing water monitoring well logs, indicate that the groundwater flow in the sand and gravel aquifer is to the southeast, away from the public water supply, Lake Auburn, which lies to the north of the site. However, correlations between the bedrock fracture analysis and the geophysical survey illustrate that there is potential for contamination of Lake Auburn via the bedrock aquifer.

  1. Reducing Open Cell Landfill Methane Emissions with a Bioactive Alternative Daily

    Methane and carbon dioxide are formed in landfills as wastes degrade. Molecule-for-molecule, methane is about 20 times more potent than carbon dioxide at trapping heat in the earth's atmosphere, and thus, it is the methane emissions from landfills that are scrutinized. For example, if emissions composed of 60% methane and 40% carbon dioxide were changed to a mix that was 40% methane and 60% carbon dioxide, a 30% reduction in the landfill's global warming potential would result. A 10% methane, 90% carbon dioxide ratio will result in a 75% reduction in global warming potential compared to the baseline. Gas collection from a closed landfill can reduce emissions, and it is sometimes combined with a biocover, an engineered system where methane oxidizing bacteria living in a medium such as compost, convert landfill methane to carbon dioxide and water. Although methane oxidizing bacteria merely convert one greenhouse gas (methane) to another (carbon dioxide), this conversion can offer significant reductions in the overall greenhouse gas contribution, or global warming potential, associated with the landfill. What has not been addressed to date is the fact that methane can also escape from a landfill when the active cell is being filled with waste. Federal regulations require that newly deposited solid waste to be covered daily with a 6 in layer of soil or an alternative daily cover (ADC), such as a canvas tarp. The aim of this study was to assess the feasibility of immobilizing methane oxidizing bacteria into a tarp-like matrix that could be used for alternative daily cover at open landfill cells to prevent methane emissions. A unique method of isolating methanotrophs from landfill cover soil was used to create a liquid culture of mixed methanotrophs. A variety of prospective immobilization techniques were used to affix the bacteria in a tarp-like matrix. Both gel encapsulation of methanotrophs and gels with liquid cores containing methanotrophs were readily made but

    In the authors business of providing district energy services, competition is the key to his being able to have a positive impact on the environment, business stability, and economic activity. In the district energy industry, the competitive options are for property owners to continue to self generate energy to meet their needs, purchase energy from a company that utilizes electricity during off-peak hours to produce chilled water or take advantage of a total solution of purchasing tri-generation energy from Trigen-Peoples District Energy Company. Tri-generation is an innovative technology which involves the simultaneous production of steam, chilled water, and electricity. The McCormick Place cogeneration project calls for producing steam and chilled water (co-) for use by the Metropolitan Pier and Exposition Authority (MPEA).

    New problems have arisen over the ability to wheel power from decentralized cogeneration and small generation sources between electric utilities or between industrial facilities within a common geographical area. This article explores the historical and current positions of the Federal Power Commission, now the Federal Energy Regulatory Commission (FERC) as it has interpreted its authority under Part II of the Federal Power Act to order the wheeling of electric power. The authors also outline and discuss related antitrust issues which often arise within the context of wheeling and the possibilities of recognizing potential antitrust violations as a factor in promoting wheeling arrangements. Concluding that Congress will not address the issue, they recommend the negotiation of wheeling rates by project sponsors to introduce flexibility and avoid more regulation and costly antitrust litigation. 21 references.

    Louisiana State University`s Energy Savings Performance Contract with CES/Way was a groundbreaking project that applied part-load cogeneration technology to a large university campus to meet chilled water and steam requirements for expansion needs. Simultaneously, the project provided these utilities at no additional out of pocket cost to the institution by using the innovative financing mechanism of performance contracting, in which project savings pay for the investment. In addition, the work is performed via a cogeneration system operating most of the year at part-load. This mechanical cogeneration project could also be termed a thermal cogeneration project, as it provides a dual thermal benefit from a single input energy source. Not only did the project achieve the projected energy savings, but the savings proved to be so dependable that the University opted for an early buyout of the project from CES/Way in 1994, after only about two years of documented savings.

    This article describes the development, calibration and validation of a combustion-cogeneration model for whole-building simulation. As part of IEA Annex 42, we proposed a parametric model for studying residentialscale cogeneration systems based on both Stirling and internal combustion engines. The model can predict the fuel use, thermal output and electrical generation of a cogeneration device in response to changing loads, coolant temperatures and flow rates, and control strategies. The model is now implemented in the publicly-available EnergyPlus, ESP-r and TRNSYS building simulation programs. We vetted all three implementations using a comprehensive comparative testing suite, and validated the model's theoretical basis through comparison to measured data. The results demonstrate acceptable-to-excellent agreement, and suggest the model can be used with confidence when studying the energy performance of cogeneration equipment in non-condensing operation.

    The microbial oxidation of methane in engineered cover soils is considered a potent option for the mitigation of emissions from old landfills or sites containing wastes of low methane generation rates. A laboratory column study was conducted in order to derive design criteria that enable construction of an effective methane oxidising cover from the range of soils that are available to the landfill operator. Therefore, the methane oxidation capacity of different soils was assessed under simulated landfill conditions. Five sandy potential landfill top cover materials with varying contents of silt and clay were investigated with respect to methane oxidation and corresponding soil gas composition over a period of four months. The soils were compacted to 95% of their specific proctor density, resulting in bulk densities of 1.4-1.7 g cm{sup -3}, reflecting considerably unfavourable conditions for methane oxidation due to reduced air-filled porosity. The soil water content was adjusted to field capacity, resulting in water contents ranging from 16.2 to 48.5 vol.%. The investigated inlet fluxes ranged from 25 to about 100 g CH{sub 4} m{sup -2} d{sup -1}, covering the methane load proposed to allow for complete oxidation in landfill covers under Western European climate conditions and hence being suggested as a criterion for release from aftercare. The vertical distribution of gas concentrations, methane flux balances as well as stable carbon isotope studies allowed for clear process identifications. Higher inlet fluxes led to a reduction of the aerated zone, an increase in the absolute methane oxidation rate and a decline of the relative proportion of oxidized methane. For each material, a specific maximum oxidation rate was determined, which varied between 20 and 95 g CH{sub 4} m{sup -2} d{sup -1} and which was positively correlated to the air-filled porosity of the soil. Methane oxidation efficiencies and gas profile data imply a strong link between oxidation capacity

    District energy systems are a major part of the energy use and delivery infrastructure of the United States. With nearly 6,000 operating systems currently in place, district energy represents approximately 800 billion BTU per hour of installed thermal production capacity, and provides over 1.1 quadrillion BTU of energy annually -- about 1.3% of all energy used in the US each year. Delivered through more that 20,000 miles of pipe, this energy is used to heat and cool almost 12 billion square feet of enclosed space in buildings that serve a diverse range of office, education, health care, military, industrial and residential needs. This Census is intended to provide a better understanding of the character and extent of district heating, cooling and cogeneration in the United States. It defines a district energy system as: Any system that provides thermal energy (steam, hot water, or chilled water) for space heating, space cooling, or process uses from a central plant, and that distributes the energy to two or more buildings through a network of pipes. If electricity is produced, the system is a cogenerating facility. The Census was conducted through surveys administered to the memberships of eleven national associations and agencies that collectively represent the great majority of the nation`s district energy system operators. Responses received from these surveys account for about 11% of all district systems in the United States. Data in this report is organized and presented within six user sectors selected to illustrate the significance of district energy in institutional, community and utility settings. Projections estimate the full extent of district energy systems in each sector.

    This report presents the results of a review of the US Environmental Protection Agency (EPA) Record of Decision System (RODS) database search conducted to identify Superfund landfill sites where a Record of Decision (ROD) has been prepared by EPA, the States or the US Army Corps of Engineers describing the selected remedy at the site. ROD abstracts from the database were reviewed to identify site information including site type, contaminants of concern, components of the selected remedy, and cleanup goals. Only RODs from landfill sites were evaluated so that the results of the analysis can be used to support the remedy selection process for the Sanitary Landfill at the Savannah River Site (SRS).

  20. Analysis of Homogeneous Charge Compression Ignition (HCCI) Engines for Cogeneration Applications

    2004-04-30

    This paper presents an evaluation of the applicability of Homogeneous Charge Compression Ignition Engines (HCCI) for small-scale cogeneration (less than 1 MWe) in comparison to five previously analyzed prime movers. The five comparator prime movers include stoichiometric spark-ignited (SI) engines, lean burn SI engines, diesel engines, microturbines and fuel cells. The investigated option, HCCI engines, is a relatively new type of engine that has some fundamental differences with respect to other prime movers. Here, the prime movers are compared by calculating electric and heating efficiency, fuel consumption, nitrogen oxide (NOx) emissions and capital and fuel cost. Two cases are analyzed. In Case 1, the cogeneration facility requires combined power and heating. In Case 2, the requirement is for power and chilling. The results show that the HCCI engines closely approach the very high fuel utilization efficiency of diesel engines without the high emissions of NOx and the expensive diesel fuel. HCCI engines offer a new alternative for cogeneration that provides a unique combination of low cost, high efficiency, low emissions and flexibility in operating temperatures that can be optimally tuned for cogeneration systems. HCCI engines are the most efficient technology that meets the oncoming 2007 CARB NOx standards for cogeneration engines. The HCCI engine appears to be a good option for cogeneration systems and merits more detailed analysis and experimental demonstration.

    The General Services Administration, through its National Capital Region, operates a district heating system - called the Heating Operation and Transmission District - that provides steam to approximately 100 government buildings in Washington, D.C. HOTD is examining a host of options that will improve its ability to provide reliable, environmentally sound, and cost-effective service to its customers. This report evaluates one of those options - cogeneration, a technology that would enable HOTD to produce steam and electricity simultaneously. The study concluded that, under current regulations, cogeneration is not attractive economically because the payback period (15 years) exceeds Federal return-on-investment guidelines. However, if the regulatory environment changes to allow wheeling (transmission of power by a non-utility power producer to another user), cogeneration would be attractive; HOTD would save anywhere from $38 million to $118 million and the investment would pay back in 7 to 10 years. Although incorporating cogeneration into the HOTD system has no strong benefit at this time, the report recommends that GSA reevaluate cogeneration in one or two years because Federal regulations regarding wheeling are under review. It also recommends that GSA work with the District of Columbia government to develop standards for cogeneration.

  2. Landfill stabilization focus area: Technology summary

    SciTech Connect (OSTI)

    1995-06-01

    Landfills within the DOE Complex as of 1990 are estimated to contain 3 million cubic meters of buried waste. The DOE facilities where the waste is predominantly located are at Hanford, the Savannah River Site (SRS), the Idaho National Engineering Laboratory (INEL), the Los Alamos National Laboratory (LANL), the Oak Ridge Reservation (ORR), the Nevada Test Site (NTS), and the Rocky Flats Plant (RFP). Landfills include buried waste, whether on pads or in trenches, sumps, ponds, pits, cribs, heaps and piles, auger holes, caissons, and sanitary landfills. Approximately half of all DOE buried waste was disposed of before 1970. Disposal regulations at that time permitted the commingling of various types of waste (i.e., transuranic, low-level radioactive, hazardous). As a result, much of the buried waste throughout the DOE Complex is presently believed to be contaminated with both hazardous and radioactive materials. DOE buried waste typically includes transuranic-contaminated radioactive waste (TRU), low-level radioactive waste (LLW), hazardous waste per 40 CFR 26 1, greater-than-class-C waste per CFR 61 55 (GTCC), mixed TRU waste, and mixed LLW. The mission of the Landfill Stabilization Focus Area is to develop, demonstrate, and deliver safer,more cost-effective and efficient technologies which satisfy DOE site needs for the remediation and management of landfills. The LSFA is structured into five technology areas to meet the landfill remediation and management needs across the DOE complex. These technology areas are: assessment, retrieval, treatment, containment, and stabilization. Technical tasks in each of these areas are reviewed.

    The Yolo County Department of Planning and Public Works is constructing a full-scale bioreactor landfill as a part of the Environmental Protection Agency's (EPA) Project XL program to develop innovative approaches for carbon sequestration and greenhouse emission control. The overall objective is to manage landfill solid waste for rapid waste decomposition and maximum landfill gas generation and capture for carbon sequestration and greenhouse emission control. Waste decomposition is accelerated by improving conditions for either the aerobic or anaerobic biological processes and involves circulating controlled quantities of liquid (leachate, groundwater, gray water, etc.), and, in the aerobic process, large volumes of air. The first phase of the project entails the construction of a 12-acre module that contains a 6-acre anaerobic cell, a 3.5-acre anaerobic cell, and a 2.5-acre aerobic cell at the Yolo County Central Landfill near Davis, California. The cells are highly instrumented to monitor bioreactor performance. Liquid addition has commenced in the 3.5-acre anaerobic cell and the 6-acre anaerobic cell. Construction of the 2.5-acre aerobic cell is nearly complete with only the biofilter remaining and is scheduled to be complete by the end of August 2003. The current project status and preliminary monitoring results are summarized in this report.

    Developing safe, reliable, cost-effective, and efficient hydrogen-electricity co-generation systems is an important step in the quest for national energy security and minimized reliance on foreign oil. This project aimed to, through materials research, develop a cost-effective advanced technology cogenerating hydrogen and electricity directly from distributed natural gas and/or coal-derived fuels. This advanced technology was built upon a novel hybrid module composed of solid-oxide fuel-assisted electrolysis cells (SOFECs) and solid-oxide fuel cells (SOFCs), both of which were in planar, anode-supported designs. A SOFEC is an electrochemical device, in which an oxidizable fuel and steam are fed to the anode and cathode, respectively. Steam on the cathode is split into oxygen ions that are transported through an oxygen ion-conducting electrolyte (i.e. YSZ) to oxidize the anode fuel. The dissociated hydrogen and residual steam are exhausted from the SOFEC cathode and then separated by condensation of the steam to produce pure hydrogen. The rationale was that in such an approach fuel provides a chemical potential replacing the external power conventionally used to drive electrolysis cells (i.e. solid oxide electrolysis cells). A SOFC is similar to the SOFEC by replacing cathode steam with air for power generation. To fulfill the cogeneration objective, a hybrid module comprising reversible SOFEC stacks and SOFC stacks was designed that planar SOFECs and SOFCs were manifolded in such a way that the anodes of both the SOFCs and the SOFECs were fed the same fuel, (i.e. natural gas or coal-derived fuel). Hydrogen was produced by SOFECs and electricity was generated by SOFCs within the same hybrid system. A stand-alone 5 kW system comprising three SOFEC-SOFC hybrid modules and three dedicated SOFC stacks, balance-of-plant components (including a tailgas-fired steam generator and tailgas-fired process heaters), and electronic controls was designed, though an overall

    A research team at University of Rome La Sapienza designed and developed a new Stirling Ringbom engine, named ULS-RSE 1, with the aim to make it simple and cheap, to accelerate the pre-commercialization process and facilitate the diffusion of Stirling technology. The engine is a by 2.5 kW mechanical power and about 9 kW thermal power unit, since it can operate as cogeneration unit. The heat source is a multi-fuel furnace of 14 kW thermal power with a combustion efficiency of 75%. In order to reduce its weight, the compressor device (power piston, cross-head, rod and cylinder) is made of Ergal, an aluminum alloy. The seal of the piston is a charged PTFE (bronze or graphite); the characteristics of this material are the long life and the high working performance (260 C, 600 bar and 10 m/s of mean piston speed). The hot section has no crank mechanism. The stainless steel displacer has a seal guide of Peek, preventing the effects of high working temperatures (about 1000 K). Two dampers are located at the top, in order to regulate the displacer piston stroke. The displacer free piston runs into a sort of stainless steel container, cylinder shaped. The corrugated nickel foil heat exchangers are located in the space between the hot section wall and the container. The regenerator, unusually long 12 cm, consists of a stainless steel foil matrix (thickness of 0.05 mm). To improve the thermal exchange in the hot and cold working spaces, external fins are also provided, respectively longitudinal and horizontal ones. The realization of a test bench is in progress.

  18. Proposal of a novel multifunctional energy system for cogeneration of coke, hydrogen, and power - article no. 052001

    SciTech Connect (OSTI)

    Jin, H.G.; Sun, S.; Han, W.; Gao, L.

    2009-09-15

    This paper proposes a novel multifunctional energy system (MES), which cogenerates coke, hydrogen, and power, through the use of coal and coke oven gas (COG). In this system, a new type of coke oven, firing coal instead of COG as heating resource for coking, is adopted. The COG rich in H{sub 2} is sent to a pressure swing adsorption (PSA) unit to separate about 80% of hydrogen first, and then the PSA purge gas is fed to a combined cycle as fuel. The new system combines the chemical processes and power generation system, along with the integration of chemical conversion and thermal energy utilization. In this manner, both the chemical energy of fuel and thermal energy can be used more effectively. With the same inputs of fuel and the same output of coking heat, the new system can produce about 65% more hydrogen than that of individual systems. As a result, the thermal efficiency of the new system is about 70%, and the exergy efficiency is about 66%. Compared with individual systems, the primary energy saving ratio can reach as high as 12.5%. Based on the graphical exergy analyses, we disclose that the integration of synthetic utilization of COG and coal plays a significant role in decreasing the exergy destruction of the MES system. The promising results obtained may lead to a clean coal technology that will utilize COG and coal more efficiently and economically.

    This guidebook focuses on cogeneration development. It is one of a series of four guidebooks recently prepared to introduce the energy developer to the federal, state and local agencies that regulate energy facilities in Idaho, Montana, Oregon, and Washington (the Bonneville Power Administration Service Territory). It was prepared specifically to help cogeneration developers obtain the permits, licenses and approvals necessary to construct and operate a cogeneration facility. The regulations, agencies and policies described herein are subject to change. Changes are likely to occur whenever energy or a project becomes a political issue, a state legislature meets, a preexisting popular or valuable land use is thought threatened, elected and appointed officials change, and new directions are imposed on states and local governments by the federal government. Accordingly, cogeneration developers should verify and continuously monitor the status of laws and rules that might affect their plans. Developers are cautioned that the regulations described herein may only be a starting point on the road to obtaining all the necessary permits.

    Highlights: ? Current data on in situ aeration effects from the first Austrian full-scale case study. ? Data on lasting waste stabilisation after aeration completion. ? Information on the transferability of results from lab- to full-scale aeration. - Abstract: Sustainable landfilling has become a fundamental objective in many modern waste management concepts. In this context, the in situ aeration of landfills has been recognised for its potential to convert conventional anaerobic landfills into biological stabilised state, whereby both current and potential (long-term) emissions of the landfilled waste are mitigated. In recent years, different in situ aeration concepts have been successfully applied in Europe, North America and Asia, all pursuing different objectives and strategies. In Austria, the first full-scale application of in situ landfill aeration by means of low pressure air injection and simultaneous off-gas collection and treatment was implemented on an old, small municipal solid waste (MSW) landfill (2.6 ha) in autumn 2007. Complementary laboratory investigations were conducted with waste samples taken from the landfill site in order to provide more information on the transferability of the results from lab- to full-scale aeration measures. In addition, long-term emission development of the stabilised waste after aeration completion was assessed in an ongoing laboratory experiment. Although the initial waste material was described as mostly stable in terms of the biological parameters gas generation potential over 21 days (GP{sub 21}) and respiration activity over 4 days (RA{sub 4}), the lab-scale experiments indicated that aeration, which led to a significant improvement of leachate quality, was accompanied by further measurable changes in the solid waste material under optimised conditions. Even 75 weeks after aeration completion the leachate, as well as gaseous emissions from the stabilised waste material, remained low and stayed below the authorised

    Highlights: Black-Right-Pointing-Pointer Aerobic granular sludge SBR was used to treat real landfill leachate. Black-Right-Pointing-Pointer COD removal was analyzed kinetically using a modified model. Black-Right-Pointing-Pointer Characteristics of nitrogen removal at different ammonium inputs were explored. Black-Right-Pointing-Pointer DO variations were consistent with the GSBR performances at low ammonium inputs. - Abstract: Granule sequencing batch reactors (GSBR) were established for landfill leachate treatment, and the COD removal was analyzed kinetically using a modified model. Results showed that COD removal rate decreased as influent ammonium concentration increasing. Characteristics of nitrogen removal at different influent ammonium levels were also studied. When the ammonium concentration in the landfill leachate was 366 mg L{sup -1}, the dominant nitrogen removal process in the GSBR was simultaneous nitrification and denitrification (SND). Under the ammonium concentration of 788 mg L{sup -1}, nitrite accumulation occurred and the accumulated nitrite was reduced to nitrogen gas by the shortcut denitrification process. When the influent ammonium increased to a higher level of 1105 mg L{sup -1}, accumulation of nitrite and nitrate lasted in the whole cycle, and the removal efficiencies of total nitrogen and ammonium decreased to only 35.0% and 39.3%, respectively. Results also showed that DO was a useful process controlling parameter for the organics and nitrogen removal at low ammonium input.

    The Y-12 Plant, K-25 Site, and ORNL are managed by DOE`s Operating Contractor (OC), Martin Marietta Energy Systems, Inc. (Energy Systems) for DOE. Operation associated with the facilities by the Operating Contractor and subcontractors, DOE contractors and the DOE Federal Building result in the generation of industrial solid wastes as well as construction/demolition wastes. Due to the waste streams mentioned, the Y-12 Industrial Waste Landfill IV (IWLF-IV) was developed for the disposal of solid industrial waste in accordance to Rule 1200-1-7, Regulations Governing Solid Waste Processing and Disposal in Tennessee. This revised operating document is a part of a request for modification to the existing Y-12 IWLF-IV to comply with revised regulation (Rule Chapters 1200-1-7-.01 through 1200-1-7-.08) in order to provide future disposal space for the ORR, Subcontractors, and the DOE Federal Building. This revised operating manual also reflects approved modifications that have been made over the years since the original landfill permit approval. The drawings referred to in this manual are included in Drawings section of the package. IWLF-IV is a Tennessee Department of Environmental and Conservation/Division of Solid Waste Management (TDEC/DSWM) Class 11 disposal unit.

    Highlights: ► An average GHG emission factor for the collection and transport of municipal solid waste in South Africa is calculated. ► A range of GHG emission factors for different types of landfills (including dumps) in South Africa are calculated. ► These factors are compared internationally and their implications for South Africa and developing countries are discussed . ► Areas for new research are highlighted. - Abstract: Greenhouse gas (GHG) emission factors are used with increased frequency for the accounting and reporting of GHG from waste management. However, these factors have been calculated for developed countries of the Northern Hemisphere and are lacking for developing countries. This paper shows how such factors have been developed for the collection, transport and landfilling of municipal waste in South Africa. As such it presents a model on how international results and methodology can be adapted and used to calculate country-specific GHG emission factors from waste. For the collection and transport of municipal waste in South Africa, the average diesel consumption is around 5 dm{sup 3} (litres) per tonne of wet waste and the associated GHG emissions are about 15 kg CO{sub 2} equivalents (CO{sub 2} e). Depending on the type of landfill, the GHG emissions from the landfilling of waste have been calculated to range from −145 to 1016 kg CO{sub 2} e per tonne of wet waste, when taking into account carbon storage, and from 441 to 2532 kg CO{sub 2} e per tonne of wet waste, when carbon storage is left out. The highest emission factor per unit of wet waste is for landfill sites without landfill gas collection and these are the dominant waste disposal facilities in South Africa. However, cash strapped municipalities in Africa and the developing world will not be able to significantly upgrade these sites and reduce their GHG burdens if there is no equivalent replacement of the Clean Development Mechanism (CDM) resulting from the Kyoto agreement

    The Town of Islip, New York, encompasses 285 square kilometers (110 square miles) along the southern shore of Suffolk County, Long Island. The Town relied upon Blydenburgh Landfill for the disposal of its estimated 290 kilotonnes per year (320,000 tons per year) of municipal solid waste (MSW) without having to contract for off-Long Island hauling and disposal. In 1983, the Long Island Landfill Law was enacted and effectively banned landfilling of raw garbage on most of Long Island after December 18, 1990. The act precluded the economic development of new landfill capacity for the Town. Blydenburgh Landfill was projected to reach capacity in early 1987 and close. To conserve landfill capacity for residential use, the Town prohibited commercial haulers from the landfill in the fall of 1986. In response, the Mobro barge departed Long Island City on March 22, 1987 loaded with commercial MSW that was no longer accepted at the Blydenburgh site. Negative publicity surrounded the Mobro barge and the continuing need to provide for waste disposal. In response, the New York State Department of Environmental Conservation (NYSDEC) and the Town`s Resource Recovery Agency entered into an Order on Consent on May 12, 1987. This allowed for continued operations and a vertical MSW {open_quotes}piggyback{close_quotes} expansion on top of a closed and capped portion of the existing 181,000 square meter (44.8 acre) landfill mound. In addition, the Order on Consent permitted construction of a separate 12,000 square meter (3.0 acre) ash residue vertical piggyback expansion adjacent to the MSW piggyback expansion. Both expansions were designed for and constructed on top of existing landfilled MSW.

    Highlights: Black-Right-Pointing-Pointer We analyze two decades of landfill mining research regarding trends and topics. Black-Right-Pointing-Pointer So far landfill mining has mainly been used to solve waste management issues. Black-Right-Pointing-Pointer A new perspective on landfills as resource reservoirs is emerging. Black-Right-Pointing-Pointer The potential of resource extraction from landfills is significant. Black-Right-Pointing-Pointer We outline several key challenges for realization of resource extraction from landfills. - Abstract: Landfills have historically been seen as the ultimate solution for storing waste at minimum cost. It is now a well-known fact that such deposits have related implications such as long-term methane emissions, local pollution concerns, settling issues and limitations on urban development. Landfill mining has been suggested as a strategy to address such problems, and in principle means the excavation, processing, treatment and/or recycling of deposited materials. This study involves a literature review on landfill mining covering a meta-analysis of the main trends, objectives, topics and findings in 39 research papers published during the period 1988-2008. The results show that, so far, landfill mining has primarily been seen as a way to solve traditional management issues related to landfills such as lack of landfill space and local pollution concerns. Although most initiatives have involved some recovery of deposited resources, mainly cover soil and in some cases waste fuel, recycling efforts have often been largely secondary. Typically, simple soil excavation and screening equipment have therefore been applied, often demonstrating moderate performance in obtaining marketable recyclables. Several worldwide changes and recent research findings indicate the emergence of a new perspective on landfills as reservoirs for resource extraction. Although the potential of this approach appears significant, it is argued that

    The disposal of industrial waste such as oil sludges, waste plastic, lubricant oils, paper and wood poses serious problems due to the ever increasing amount of material to be disposed of and to the difficulty in finding new dumping sites. The interest in energy recovery technologies is accordingly on the increase. In particular, large amounts of waste wood are simply burned or thrown away causing considerable environmental damage. In this context the co-generation technique represents one of the possible solutions for efficient energy conversion. The present paper proposes the employment of a Stirling engine as prime mover in a co-generation set equipped with a wood gasifier. A Stirling engine prototype previously developed in a joint project with Mase Generators, an Italian manufacturer of fixed and portable electrogenerators, is illustrated and its design is described.

    Foster Wheeler Power Systems Inc., and its partners--Petrox SA Refineria de Petroleo and Empresa Nacional de Petroleo (ENAP), the Chilean national oil company--closed on the financing of Petropower Energia Limitada, a $237 million financed combination delayed coker-cogeneration facility. The facility is now under construction adjacent to Petrox`s 84,000 b/d Talcahuano refinery, near Concepcion. In addition to the low interest rate of 7.36%--only 170 basis points over the 10 year US Treasury yield--the project was rated investment-grade by Standard and Poor`s. The Petropower project also has the distinction of having the longest term--18 years--for any project financing in Latin America. The project is unique in other ways: it is the Republic of Chile`s first public/private partnership and also the first project to combine petroleum coking technology with cogeneration technology in a single project financing. The paper discusses risk assumption, the Petropower project, organization, delayed coker facility, hydrotreater unit, cogeneration facility, environmental assessment, Chile`s changing market, and project benefit.

    A quantitative system dynamics model was created to evaluate the economic and environmental tradeoffs between biomass to electricity and to liquid fuel using MSW biomass in the state of California as a case study. From an environmental perspective, landfilling represents the worst use of MSW over time, generating more greenhouse gas (GHG) emissions compared to converting MSW to liquid fuel or to electricity. MSW to ethanol results in the greatest displacement of GHG emissions per dollar spent compared to MSW to electricity. MSW to ethanol could save the state of California approximately $60 billion in energy costs by 2050 compared to landfilling, while also reducing GHG emissions state-wide by approximately 140 million metric tons during that timeframe. MSW conversion to electricity creates a significant cost within the state's electricity sector, although some conversion technologies are cost competitive with existing renewable generation.

  14. Dynamic model of Italy`s Progetto Energia cogeneration plants aims to better predict plant performance, cut start-up costs

    1996-12-31

    Over the next four years, the Progetto Energia project will be building several cogeneration plants to help satisfy the increasing demands of Italy`s industrial users and the country`s demand for electrical power. Located at six different sites within Italy, these combined-cycle cogeneration plants will supply a total of 500 MW of electricity and 100 tons/hr of process steam to Italian industries and residences. To ensure project success, a dynamic model of the 50-MW base unit was developed. The goal established for the model was to predict the dynamic behavior of the complex thermodynamic system in order to assess equipment performance and control system effectiveness for normal operation and, more importantly, abrupt load changes. In addition to fulfilling its goals, the dynamic study guided modifications to controller logic that significantly improved steam drum pressure control and bypassed steam desuperheating performance simulations of normal and abrupt transient events allowed engineers to define optimum controller gain coefficients. The dynamic study will undoubtedly reduce the associated plant start-up costs and contribute to a smooth commercial plant acceptance. As a result of the work, the control system has already been through its check-out and performance evaluation, usually performed during the plant start-up phase. Field engineers will directly benefit from this effort to identify and resolve control system {open_quotes}bugs{close_quotes} before the equipment reaches the field. High thermal efficiency, rapid dispatch and high plant availability were key reasons why the natural gas combined-cycle plant was chosen. Other favorable attributes of the combined-cycle plant contributing to the decision were: Minimal environmental impact; a simple and effective process and control philosophy to result in safe and easy plant operation; a choice of technologies and equipment proven in a large number of applications.

    Highlights: ? First measurements of N{sub 2}O and CH{sub 4} emissions from an MBT landfill. ? High N{sub 2}O emissions from recently deposited material. ? N{sub 2}O emissions associated with aeration and the occurrence of nitrite and nitrate. ? Strong negative correlation between CH{sub 4} and N{sub 2}O production activity. - Abstract: Mechanical biological treatment (MBT) is an effective technique, which removes organic carbon from municipal solid waste (MSW) prior to deposition. Thereby, methane (CH{sub 4}) production in the landfill is strongly mitigated. However, direct measurements of greenhouse gas emissions from full-scale MBT landfills have not been conducted so far. Thus, CH{sub 4} and nitrous oxide (N{sub 2}O) emissions from a German MBT landfill in operation as well as their concentrations in the landfill gas (LFG) were measured. High N{sub 2}O emissions of 20200 g CO{sub 2} eq. m{sup ?2} h{sup ?1} magnitude (up to 428 mg N m{sup ?2} h{sup ?1}) were observed within 20 m of the working face. CH{sub 4} emissions were highest at the landfill zone located at a distance of 3040 m from the working face, where they reached about 10 g CO{sub 2} eq. m{sup ?2} h{sup ?1}. The MBT material in this area has been deposited several weeks earlier. Maximum LFG concentration for N{sub 2}O was 24.000 ppmv in material below the emission hotspot. At a depth of 50 cm from the landfill surface a strong negative correlation between N{sub 2}O and CH{sub 4} concentrations was observed. From this and from the distribution pattern of extractable ammonium, nitrite, and nitrate it has been concluded that strong N{sub 2}O production is associated with nitrification activity and the occurrence of nitrite and nitrate, which is initiated by oxygen input during waste deposition. Therefore, CH{sub 4} mitigation measures, which often employ aeration, could result in a net increase of GHG emissions due to increased N{sub 2}O emissions, especially at MBT landfills.

    Methane is an important contributor to global warming with a total climate forcing estimated to be close to 20% that of carbon dioxide (CO2) over the past two decades. The largest anthropogenic source of methane in the US is 'conventional' landfills, which account for over 30% of anthropogenic emissions. While controlling greenhouse gas emissions must necessarily focus on large CO2 sources, attention to reducing CH4 emissions from landfills can result in significant reductions in greenhouse gas emissions at low cost. For example, the use of 'controlled' or bioreactor landfilling has been estimated to reduce annual US greenhouse emissions by about 15-30 million tons of CO2 carbon (equivalent) at costs between $3-13/ton carbon. In this project we developed or advanced new management approaches, landfill designs, and landfill operating procedures for bioreactor landfills. These advances are needed to address lingering concerns about bioreactor landfills (e.g., efficient collection of increased CH4 generation) in the waste management industry, concerns that hamper bioreactor implementation and the consequent reductions in CH4 emissions. Collectively, the advances described in this report should result in better control of bioreactor landfills and reductions in CH4 emissions. Several advances are important components of an Intelligent Bioreactor Management Information System (IBM-IS).

    Customarily, electricity is generated in a utility power plant while thermal energy is generated in a heating/cooling plant; the electricity produced at the power plant is transmitted to the heating/cooling plant to power equipments. These two separate systems waste vast amounts of heat and result in individual efficiencies of about 35%. Cogeneration is the sequential production of power (electrical or mechanical) and thermal energy (process steam, hot/chilled water) from a single power source; the reject heat of one process issued as input into the subsequent process. Cogeneration increases the efficiency of these stand-alone systems by producing these two products sequentially at one location using a small additional amount of fuel, rendering the system efficiency greater than 70%. This report discusses cogeneration technologies as applied to wood fuel fired system.

    Several recent models have attempted to simulate or assess the probability and consequences of the leakage of aqueous contaminant leakage from solid waste landfills. These models incorporate common factors, including climatological and geological characteristics. Each model, however, employs a unique approach to the problem, assigns different relative weights to factors, and relies upon extrapolated small-scale experimental data and/or subjective judgment in predicting the full-scale landfill failure mechanisms leading to contaminant migration. As a result, no two models are likely to equally assess a given landfill, and no one model has been validated as a predictor of long-term performance. The United States Air Force maintains a database for characterization of potential hazardous waste sites. Records include more than 500 landfills, providing such information as waste, soil, aquifer, monitoring location data, and the results of sample testing. Through analysis of this information, nearly 300 landfills were assessed to have sufficiently, partially, or inadequately contained hazardous constituents of the wastes placed within them.

    The US military uses millions of Btu`s of thermal energy to heat, cool and deliver process thermal energy to buildings on military bases, much of which is transmitted through a pipeline system incorporating thousands of miles of pipe. Much of this pipeline system is in disrepair and is nearing the end of its useful life, and the boilers which supply it are old and often inefficient. In 1993, Brookhaven National Laboratory (BNL) proposed to SERDP a three-year effort to develop advanced systems of coupled diesel cogenerators and absorption chillers which would be particularly useful in providing a continuation of the services now provided by increasingly antiquated district systems. In mid-February, 1995, BNL learned that all subsequent funding for our program had been canceled. BNL staff continued to develop the Program Plan and to adhere to the requirements of the Execution Plan, but began to look for ways in which the work could be made relevant to Navy and DoD energy needs even without the extensive development plan formerly envisioned. The entire program was therefore re-oriented to look for ways in which small scale cogeneration and absorption chilling technologies, available through procurement rather than development, could provide some solutions to the problem of deteriorated district heating systems. The result is, we believe, a striking new approach to the provision of building services on military bases: in many cases, serious study should be made of the possibility that the old district heating system should be removed or abandoned, and small-scale cogenerators and absorption chillers should be installed in each building. In the remainder of this Summary, we develop the rationale behind this concept and summarize our findings concerning the conditions under which this course of action would be advisable and the economic benefits which will accrue if it is followed. The details are developed in the succeeding sections of the report.

    1985-01-01

    Under the Formerly Utilized Sites Remedial Action Program, the US Department of Energy began excavating contaminated materials from the Middlesex Municipal landfill in 1984. A total of 16,000 mT of landfill materials covering a 0.2-ha area was excavated, of which 11,000 mT was contaminated and has been transported to the nearby sampling plant site for interim storage. Based on the pathway analysis for the onsite and near-site resident scenarios, the radiation dose rates and radionuclide concentrations in groundwater would be below the regulatory requirements for both the short-term and long-term scenarios. Hence, the potential health risks to maximally exposed individuals due to radioactive releases from the Middlesex landfill would be insignificant.

    1980-09-01

    The primary objective of the TASE program is to determine the probable consequences to the environment and to public health and safety resulting from widespread implementation of major solar and renewable resource technologies. The specific principal Phase I objective is to determine the levels of residuals most likely to result throughout the complete energy cycle from the utilization of each of the solar and renewable resource technologies. Three basic technologies for recovering energy from M SW are considered in this study. These are: (1) direct combustion using a waterwall incinerator in which the heat from burning refuse is converted to steam by circulating water in steel tubes jacketing the interior of the incinerator; (2) manufacture of a relatively uniform shredded, pulverized or pelleted refuse-derived fuel (RDF) for supplemental firing in a utility boiler; and (3) pyrolysis or destructive distillation of MSW to extract a low-Btu fuel gas. While resource recovery and energy recovery systems can be installed independently, the processes described here include both energy and resource recovery systems as well as necessary pollution control equipment for gaseous emissions. To meet the Phase I objective, LBL staff have characterized the individual application associated with each general technology; calculated operational residuals generated by each application; determined the input capital requirements and, when possible, annual operating input requirements; and have identified the technical and institutional constraints for the widespread implementation of each application. A description is presented of the energy and material development cycle required for the implementation of each technology. The capital requirements are compiled and presented in a SEAS system format.

    It has become increasingly clear in the last few years that the vast majority of municipal solid waste landfills produce leachate that contains elevated levels of tritium. The authors recently conducted a study of landfills in New York and New Jersey and found that the mean concentration of tritium in the leachate from ten municipal solid waste (MSW) landfills was 33,800 pCi/L with a peak value of 192,000 pCi/L. A 2003 study in California reported a mean tritium concentration of 99,000 pCi/L with a peak value of 304,000 pCi/L. Studies in Pennsylvania and the UK produced similar results. The USEPA MCL for tritium is 20,000 pCi/L. Tritium is also manifesting itself as landfill gas and landfill gas condensate. Landfill gas condensate samples from landfills in the UK and California were found to have tritium concentrations as high as 54,400 and 513,000 pCi/L, respectively. The tritium found in MSW leachate is believed to derive principally from gaseous tritium lighting devices used in some emergency exit signs, compasses, watches, and even novelty items, such as 'glow stick' key chains. This study reports the findings of recent surveys of leachate from a number of municipal solid waste landfills, both open and closed, from throughout the United States and Europe. The study evaluates the human health and ecological risks posed by elevated tritium levels in municipal solid waste leachate and landfill gas and the implications to their safe management. We also assess the potential risks posed to solid waste management facility workers exposed to tritium-containing waste materials in transfer stations and other solid waste management facilities.

    Not so long ago, in the good old days, the energy supply to a health care facility was one of the most stable. The local utility provided what was needed at a reasonable cost. Now the energy industry is being deregulated. Major uncertainties exist in all parts of the energy industry. Since reasonably priced and readily available energy is mandatory for a health care facility operation, the energy industry uncertainties reverberate through the health care industry. This article reviews how the uncertainty of electric utility deregulation was converted to an opportunity to implement the ultimate energy conservation project--cogeneration. The project development was made essentially risk free by tailoring project development to deregulation. Costs and financial exposure were minimized by taking numerous small steps in sequence. Valley Medical Center, by persevering with the development of a cogeneration plant, has been able to reduce its energy costs and more importantly, stabilize its energy supply and costs for many years to come. This article reviews activities in two arenas, internal project development and external energy industry developments, by periodically updating each arena and showing how external developments affected the project.

    The high cost of waste containment has sparked interest in low cost and effective strategies of containing wastes. Paper mill sludges have been effectively used as the impermeable barrier in landfill covers. Since paper mill sludges are viewed as a waste material, the sludge is given to the landfill owner at little or no cost. Thus, when a clay soil is not locally available to use as the impermeable barrier in a cover system, paper sludge barriers can save $20,000 to $50,000 per acre in construction costs. This study looks at the utilization and performance of blended and primary paper sludge as landfill capping material. To determine the effectiveness of paper sludge as an impermeable barrier layer, test pads were constructed to simulate a typical landfill cover with paper sludge and clay as the impermeable barrier and were monitored for infiltration rates for five years. Long-term hydraulic conductivity values estimated from the leachate generation rates of the test pads indicate that paper sludge provides an acceptable hydraulic barrier.

  18. Organic carbon cycling in landfills: Model for a continuum approach

    1997-09-01

    Organic carbon cycling in landfills can be addressed through a continuum model where the end-points are conventional anaerobic digestion of organic waste (short-term analogue) and geologic burial of organic material (long-term analogue). Major variables influencing status include moisture state, temperature, organic carbon loading, nutrient status, and isolation from the surrounding environment. Bioreactor landfills which are engineered for rapid decomposition approach (but cannot fully attain) the anaerobic digester end-point and incur higher unit costs because of their high degree of environmental isolation and control. At the other extreme, uncontrolled land disposal of organic waste materials is similar to geologic burial where organic carbon may be aerobically recycled to atmospheric CO{sub 2}, anaerobically converted to CH{sub 4} and CO{sub 2} during early diagenesis, or maintained as intermediate or recalcitrant forms into geologic time (> 1,000 years) for transformations via kerogen pathways. A family of improved landfill models are needed at several scales (molecular to landscape) which realistically address landfill processes and can be validated with field data.

    Biomass-based ethanol and nuclear power are two viable elements in the path to U.S. energy independence. Numerous studies suggest nuclear power could provide a practical carbon-free heat source alternative for the production of biomass-based ethanol. In order for this coupling to occur, it is necessary to examine the interfacial requirements of both nuclear power plants and bioethanol refineries. This report describes the proposed characteristics of a small cogeneration nuclear power plant, a biochemical process-based cellulosic bioethanol refinery, and a thermochemical process-based cellulosic biorefinery. Systemic and interfacial issues relating to the co-location of either type of bioethanol facility with a nuclear power plant are presented and discussed. Results indicate future co-location efforts will require a new optimized energy strategy focused on overcoming the interfacial challenges identified in the report.

    This paper develops the coordination of a load-shedding scheme for a large industrial customer with several cogenerator units. A detailed description of each design procedure is included. The loads are tripped by the underfrequency relays, to prevent the power system from collapse when the plant becomes isolated, due to a utility service outage. Different system fault cases have been selected to derive the proper formulation of a load-shedding scheme, according to the historical operation records. The key factors, such as frequency settings, number of load-shedding steps, size and location of the loads to be tripped, relay time delay, and the coordination with the generator protection scheme, were examined through the simulation of the transient stability program. The proper load-shedding scheme has been designed, and the related hardware has been installed in the plant, to keep the system from blackout when the disturbance occurs.

    Large amounts of solid waste are disposed in landfills and the potential of particulate matter (PM) emissions into the atmosphere is significant. Particulate matter emissions in landfills are the result of resuspension from the disposed waste and other activities such as mechanical recycling and composting, waste unloading and sorting, the process of coating residues and waste transport by trucks. Measurements of ambient levels of inhalable particulate matter (PM{sub 10}) were performed in a landfill site located at Chania (Crete, Greece). Elevated PM{sub 10} concentrations were measured in the landfill site during several landfill operations. It was observed that the meteorological conditions (mainly wind velocity and temperature) influence considerably the PM{sub 10} concentrations. Comparison between the PM{sub 10} concentrations at the landfill and at a PM{sub 10} background site indicates the influence of the landfill activities on local concentrations at the landfill. No correlation was observed between the measurements at the landfill and the background sites. Finally, specific preventing measures are proposed to control the PM concentrations in landfills.

    Passive Soil Vapor Extraction was tested at the Chemical Waste Landfill (CWL) site at Sandia National Laboratories, New Mexico (SNLIW). Data collected included ambient pressures, differential pressures between soil gas and ambient air, gas flow rates into and out of the soil and concentrations of volatile organic compounds (VOCS) in vented soil gas. From the differential pressure and flow rate data, estimates of permeability were arrived at and compared with estimates from other studies. Flow, differential pressure, and ambient pressure data were collected for nearly 30 days. VOC data were collected for two six-hour periods during this time. Total VOC emissions were calculated and found to be under the limit set by the Resource Conservation and Recovery Act (RCRA). Although a complete process evaluation is not possible with the data gathered, some of the necessary information for designing a passive venting process was determined and the important parameters for designing the process were indicated. More study is required to evaluate long-term VOC removal using passive venting and to establish total remediation costs when passive venting is used as a polishing process following active soil vapor extraction.

    The Department of Energy, under the Clean Coal Technology program, proposes to provide cost-shared financial assistance for the construction of a utility-scale circulating fluidized bed technology cogeneration facility by York County Energy Partners, L.P (YCEP). YCEP, a project company of ir Products and Chemicals, Inc., would design, construct and operate a 250 megawatt (gross) coal-fired cogeneration facility on a 38-acre parcel in North Codorus Township, York County, Pennsylvania. The facility would be located adjacent to the P. H. Glatfelter Company paper mill, the proposed steam host. Electricity would be delivered to Metropolitan Edison Company. The facility would demonstrate new technology designed to greatly increase energy efficiency and reduce air pollutant emissions over current generally available commercial technology which utilizes coal fuel. The facility would include a single train circulating fluidized bed boiler, a pollution control train consisting of limestone injection for reducing emissions of sulfur dioxide by greater than 92 percent, selective non-catalytic reduction for reducing emissions of nitrogen oxides, and a fabric filter (baghouse) for reducing emissions of particulates. Section II of this report provides a general description of the facility. Section III describes the site specifics associated with the facility when it was proposed to be located in West Manchester Township. After the Cooperative Agreement was signed, YCEP decided to move the proposed site to North Codorus Township. The reasons for the move and the site specifics of that site are detailed in Section IV. This section of the report also provides detailed descriptions of several key pieces of equipment.

    There are few published data on the field performance of surface hydraulic barriers (SHBs) used in waste containment or remediation applications. In contrast, operational data for liner systems used beneath landfills are widely available. These data are frequently collected and reported as a facility permit condition. This paper uses leachate collection system (LCS) and leak detection system (LDS) liquid flow rate and chemical quality data collected from modem landfill double-liner systems to infer the likely hydraulic performance of SHBs. Operational data for over 200 waste management unit liner systems are currently being collected and evaluated by the authors as part of an ongoing research investigation for the United States Environmental Protection Agency (USEPA). The top liner of the double-liner system for the units is either a geomembrane (GMB) alone, geomembrane overlying a geosynthetic clay liner (GMB/GCL), or geomembrane overlying a compacted clay liner (GMB/CCL). In this paper, select data from the USEPA study are used to: (i) infer the likely efficiencies of SHBs incorporating GMBs and overlain by drainage layers; and (ii) evaluate the effectiveness of SHBs in reducing water infiltration into, and drainage from, the underlying waste (i.e., source control). SHB efficiencies are inferred from calculated landfill liner efficiencies and then used to estimate average water percolation rates through SHBs as a function of site average annual rainfall. The effectiveness of SHBs for source control is investigated by comparing LCS liquid flow rates for open and closed landfill cells. The LCS flow rates for closed cells are also compared to the estimated average water percolation rates through SHBs presented in the paper.

    Highlights: • Partial oxidation of landfill leachate in supercritical water was investigated. • The process was optimized by Box–Behnken design and response surface methodology. • GY{sub H2}, TRE and CR could exhibit up to 14.32 mmol·gTOC{sup −1}, 82.54% and 94.56%. • Small amounts of oxidant can decrease the generation of tar and char. - Abstract: To achieve the maximum H{sub 2} yield (GY{sub H2}), TOC removal rate (TRE) and carbon recovery rate (CR), response surface methodology was applied to optimize the process parameters for supercritical water partial oxidation (SWPO) of landfill leachate in a batch reactor. Quadratic polynomial models for GY{sub H2}, CR and TRE were established with Box–Behnken design. GY{sub H2}, CR and TRE reached up to 14.32 mmol·gTOC{sup −1}, 82.54% and 94.56% under optimum conditions, respectively. TRE was invariably above 91.87%. In contrast, TC removal rate (TR) only changed from 8.76% to 32.98%. Furthermore, carbonate and bicarbonate were the most abundant carbonaceous substances in product, whereas CO{sub 2} and H{sub 2} were the most abundant gaseous products. As a product of nitrogen-containing organics, NH{sub 3} has an important effect on gas composition. The carbon balance cannot be reached duo to the formation of tar and char. CR increased with the increase of temperature and oxidation coefficient.

    At the request of Area Completion Projects (ACP) in support of the 488-4D Landfill closure, the Savannah River National Laboratory (SRNL) has performed Hydrologic Evaluation of Landfill Performance (HELP) modeling of the planned 488-4D Ash Landfill closure cap to ensure that the South Carolina Department of Health and Environmental Control (SCDHEC) limit of no more than 12 inches of head on top of the barrier layer (saturated hydraulic conductivity of no more than 1.0E-05 cm/s) in association with a 25-year, 24-hour storm event is not projected to be exceeded. Based upon Weber 1998 a 25-year, 24-hour storm event at the Savannah River Site (SRS) is 6.1 inches. The results of the HELP modeling indicate that the greatest peak daily head on top of the barrier layer (i.e. geosynthetic clay liner (GCL) or high density polyethylene (HDPE) geomembrane) for any of the runs made was 0.079 inches associated with a peak daily precipitation of 6.16 inches. This is well below the SCDHEC limit of 12 inches.

    Highlights: • We compare two remediation scenarios; one with resource recovery and one without. • Economic analysis includes relevant direct costs and revenues for the landfill owner. • High degrees of metal and/or combustible contents are important economic factors. • Landfill tax and the access to a CHP can have a large impact on the result. • Combining landfill mining and remediation may decrease the project cost. - Abstract: This article analyzes the economic potential of integrating material separation and resource recovery into a landfill remediation project, and discusses the result and the largest impact factors. The analysis is done using a direct costs/revenues approach and the stochastic uncertainties are handled using Monte Carlo simulation. Two remediation scenarios are applied to a hypothetical landfill. One scenario includes only remediation, while the second scenario adds resource recovery to the remediation project. Moreover, the second scenario is divided into two cases, case A and B. In case A, the landfill tax needs to be paid for re-deposited material and the landfill holder does not own a combined heat and power plant (CHP), which leads to disposal costs in the form of gate fees. In case B, the landfill tax is waived on the re-deposited material and the landfill holder owns its own CHP. Results show that the remediation project in the first scenario costs about €23/ton. Adding resource recovery as in case A worsens the result to −€36/ton, while for case B the result improves to −€14/ton. This shows the importance of landfill tax and the access to a CHP. Other important factors for the result are the material composition in the landfill, the efficiency of the separation technology used, and the price of the saleable material.

    Landfill siting is one of the most problematic environmental issues facing society today for a variety of both technical and political reasons. New York State has approached many of these issues by requiring both generalized siting studies and detailed hydrogeologic evaluation of any proposed landfill site. Geographic Information Systems (GIS) have emerged as an appropriate tool for accumulating information for preliminary decision making. Recently, Goodman and others have suggested the use of a terrain suitability map (land use map) as a mechanism for simplifying landfill siting. They propose the use of existing geologic and morphologic information to eliminate large areas of New York from consideration as potential landfill locations. The study concludes that the Appalachian Plateau region (the Southern Tier), and the Erie-Ontario Plain are the most suitable areas for landfill development in the state. An evaluation of the geology at existing landfills and the impacts that relate to the facilities has shown that suitable sites do indeed exist in areas deemed unacceptable by Goodman and others. Conversely, a number of landfills located in suitable terranes have proven to be developed on less than suitable sites. While evaluation of existing information plays an obvious role in preliminary siting studies, it is not a substitute for detailed hydrogeologic investigation. It is local hydrogeological conditions that are most important in determining the suitability of a site for landfill development rather than the regional geologic context of the site.

Westinghouse Electric Corporation, through subcontracts with Babcock & Wilcox, Foster Wheeler, and ABB Combustion Engineering Systems, prepared specifications and hardware for the ACAHE tests. Argonne National Laboratory contracted with Rockwell International to conduct tests in the DOE atmospheric fluidized-bed combustion facility. This report presents an overview of the project, a description of the facility and the test hardware, the test operating conditions, a summary of the operation, and the results of analyzing specimens from several uncooled and cooled probes exposed in the facility. Extensive microstructural analyses of the base alloys, claddings, coatings, and weldments were performed on specimens exposed in several probes for different lengths of time. Alloy penetration data were determined for several of the materials as a function of specimen orientation and the exposure location in the combustor. Finally, the data were compared with earlier laboratory test data, and the long-term performance of candidate materials for air-heater applications was assessed.

    The Moyer Landfill is an inactive privately owned landfill located in Lower Providence Township in Montgomery County, Pennsylvania. The site was operated as a municipal landfill from the 1940's until April 1981, during which time it received municipal refuse and sewage sludges. According to local Federal Bureau of Investigation (FBI) officials, the landfill accepted a variety of solid and liquid hazardous wastes, including polychlorinated biphenyls (PCBs), solvents, paints, low-level radioactive wastes, and incinerated materials in bulk form and/or containerized in drums. In 1972, when the Pennsylvania Dept. of Environmental Resources (PADER) rules and regulations became more restrictive, this landfill was cited, and finally in 1981, it was closed and brought into receivership of the U.S. District Court.

    Special features of operation of a boiler operating as a combined-cycle plant and having its own furnace and burner unit are descried. The flow of flue gases on the boiler is increased due to feeding of exhaust gases of the GTU into the furnace, which intensifies the convective heat exchange. In addition, it is not necessary to preheat air in the convective heating surfaces (the boiler has no air preheater). The convective heating surfaces of the boiler are used for heating the feed water, thus replacing the regeneration extractions of the steam turbine (HPP are absent in the circuit) and partially replacing the preheating of condensate (the LPP in the circuit of the unit are combined with preheaters of delivery water). Regeneration of the steam turbine is primarily used for the district cogeneration heating purposes. The furnace and burner unit of the exhaust-heat boiler (which is a new engineering solution for the given project) ensures utilization of not only the heat of the exhaust gases of the GTU but also of their excess volume, because the latter contains up to 15% oxygen that oxidizes the combustion process in the boiler. Thus, the gas temperature at the inlet to the boiler amounts to 580{sup o}C at an excess air factor a = 3.50; at the outlet these parameters are utilized to T{sub out} = 139{sup o}C and a{sub out} = 1.17. The proportions of the GTU/boiler loads that can actually be organized at the generating unit (and have been checked by testing) are presented and the proportions of loads recommended for the most efficient operation of the boiler are determined. The performance characteristics of the boiler are presented for various proportions of GTU/boiler loads. The operating conditions of the superheater and of the convective trailing heating surfaces are presented as well as the ecological parameters of the generating unit.

    The Alternative Landfill Cover Demonstration is a large scale field test that compares the performance of various landfill cover designs in dry environments. An important component of the comparison is the change in the moisture content of the soils throughout the different cover test plots. Time Domain Reflectometry (TDR) is the primary method for the measurement of the volumetric moisture content. Each of the covers is composed of layers of varying types and densities of soils. The probes are therefore calibrated to calculate the volumetric moisture content in each of the different soils in order to gain the optimum performance of the TDR system. The demonstration plots are constructed in two phases; a different probe is used in each phase. The probe that is used in Phase 1 is calibrated for the following soils: compacted native soil, uncompacted native soil, compacted native soil mixed with 6% sodium bentonite by weight, and sand. The probe that is used in Phase 2 is calibrated for the following soils: compacted native soil, uncompacted native soil, and sand. In addition, the probes are calibrated for the varying cable lengths of the TDR probes. The resulting empirically derived equations allow for the calculation of in-situ volumetric moisture content of all of the varying soils throughout the cover test plots in the demonstration.

    The report explains the current and potential of the unconventional gas market including country profiles, major project case studies, and new technology research. It identifies the major players in the market and reports their current and forecasted projects, as well as current volume and anticipated output for specific projects. Contents are: Overview of unconventional gas; Global natural gas market; Drivers of unconventional gas sources; Forecast; Types of unconventional gas; Major producing regions Overall market trends; Production technology research; Economics of unconventional gas production; Barriers and challenges; Key regions: Australia, Canada, China, Russia, Ukraine, United Kingdom, United States; Major Projects; Industry Initiatives; Major players. Uneconomic or marginally economic resources such as tight (low permeability) sandstones, shale gas, and coalbed methane are considered unconventional. However, due to continued research and favorable gas prices, many previously uneconomic or marginally economic gas resources are now economically viable, and may not be considered unconventional by some companies. Unconventional gas resources are geologically distinct in that conventional gas resources are buoyancy-driven deposits, occurring as discrete accumulations in structural or stratigraphic traps, whereas unconventional gas resources are generally not buoyancy-driven deposits. The unconventional natural gas category (CAM, gas shales, tight sands, and landfill) is expected to continue at double-digit growth levels in the near term. Until 2008, demand for unconventional natural gas is likely to increase at an AAR corresponding to 10.7% from 2003, aided by prioritized research and development efforts. 1 app.

    The concept under investigaton was the separation of the acidogenic and the methanogenic phases of anaerobic fermentation, converting the sanitary landfill into an acid reactor and using a separate upflow fixed-film anaerobic reactor for methanogenesis. Acidic leachate from the landfill simulator was used as the influent substrate to the anaerobic reactor. The goal of the study was to improve both methane yield and concentration through nutrient addition and two-phase digestion of MSW. Sewage sludge was utilized to provide moisture, buffering capacity, nutrients, and an adequate microbial population. Single-phase systems with other enhancement techniques were also compared to the two-phase with sludge addition. Data from this study indicated that gas produced in the anaerobic reactor had methane concentration as high as 80 Mole % at the fixed-bed reactor (FBR) hydraulic retention time (HRT) of 7 days. The system reached a cumulative methane production rate of 78.6 {ell}/kg dry waste at an estimated cumulative production rate of approximately 270 {ell}/kg/yr. This performance was better than that reported in the literature for a similar type of feed. This study has also indicated that sewage sludge addition appears to be a successful enhancement technique for methane gas production from municipal solid waste. The addition of mineral nutrients and buffer solutions appears to have influenced the development of a dominant population of methanogenic bacteria in the FBR as indicated by the COD removal efficiency of 90% and 100% conversion of all influent organic acids. In terms of the overall system performance, the two-phase system was superior to the one-phase technique currently in use for methane generation.

    The information presented in this report was collected during limited site investigation activities conducted in the vicinity of Landfills 1 and 4 at Fort Lewis. The purpose of this work was to provide a means of detecting and evaluating the impacts of these inactive landfills on ground-water quality and adjacent lands. This effort included the design and construction of ground-water monitoring systems for compliance with applicable federal and state regulations governing Resource Conservation and Recovery Act (RCRA)-type landfills. Ground-water samples were collected from both existing (1981 and 1984) wells and the newly installed (1988) wells. The analytical results from the water samples indicate that the ground water in and around Landfill 1 contains limited contamination. Contaminants may include volatile organic compounds and nitrate. The primary concern in the area around Landfill 1 was the determination that ground water from two wells may contain cis-1,2-dichloroethylene and 1,1,1-trichloroethylene above drinking water standards. Nitrate levels in the downgradient wells were greater than those in upgradient wells and exceeded drinking water standards in some of the less-representative samples. Analyses of ground-water samples from wells in and around Landfill 4 indicate several contaminants may be present. These include volatile organic compounds (principally cis-1,2-dichloroethylene and 1,1,1-trichloroethylene), coliform, oil and grease, and perhaps some metals (iron and magnesium). The primary concern in the area around Landfill 4 was the determination that ground water from five wells contained cis-1,2-dichloroethylene and 1,1,1-trichloroethylene above drinking water standards. The source of contaminants beneath either landfill cannot yet be identified. Insufficient data exist to disprove or confirm either landfill as possible contributors. 19 refs., 32 figs., 17 tabs.

    The US Department of Energy (DOE), Office of Waste Management, proposes to construct and operate a solid waste landfill within the boundary of the Portsmouth Gaseous Diffusion Plant (PORTS), Piketon, Ohio. The purpose of the proposed action is to provide PORTS with additional landfill capacity for non-hazardous and asbestos wastes. The proposed action is needed to support continued operation of PORTS, which generates non-hazardous wastes on a daily basis and asbestos wastes intermittently. Three alternatives are evaluated in this environmental assessment (EA): the proposed action (construction and operation of the X-737 landfill), no-action, and offsite shipment of industrial solid wastes for disposal.

    Landfilling is the most popular disposal method for managing municipal solid waste (MSW). However, air emissions from MSW landfills have generally been unregulated until recently. Instead, EPA has focused on emissions from municipal waste combustors (MWCs), even though they only manage 15% of MSW generated in the United States. In the past, little data have been available comparing landfill and MWC air emissions. Such information is provided by this paper. It also compares emissions from waste-to-energy MWCs and fossil fuel-fired utilities with equivalent electrical generation capacity. 1 refs., 6 tabs.

    This paper reports the use of GIS mapping software—ArcMap and ArcInfo Workstation—by the Idaho National Engineering and Environmental Laboratory (INEEL) as a non-intrusive method of locating and characterizing radioactive waste in a 97-acre landfill to aid in planning cleanup efforts. The fine-scale techniques and methods used offer potential application for other burial sites for which hazards indicate a non-intrusive approach. By converting many boxes of paper shipping records in multiple formats into a relational database linked to spatial data, the INEEL has related the paper history to our current GIS technologies and spatial data layers. The wide breadth of GIS techniques and tools quickly display areas in need of remediation as well as evaluate methods of remediation for specific areas as the site characterization is better understood and early assumptions are refined.

    This is a report on geologic and hydrologic investigations of the former Municipal Landfill, Middlesex, New Jersey, conducted during 1982 and 1983 by Bechtel National, Inc. for the United States Department of Energy, Oak Ridge Operations Office. The investigations were designed to assess the feasibility of stabilizing the radioactive contamination present on site. The investigations were conducted in two phases: Phase 1 consisted of permeability tests; Phase 2 consisted of tests to ascertain the extent of hydraulic interconnection between various stratigraphic units. The investigations revealed that a complete separation of bedrock and overburden did not exist and that the clay present could not be relied upon to confine vertical migration of contaminants over the long term. 6 references, 27 figures, 6 tables.

    Frost penetration is a major environmental concern in landfill design. Freezing and thawing cycles may deteriorate the permeability of the liner or cap. In this study, the depth of frost penetration into a landfill cover that uses paper sludge as the impermeable barrier (the Hubbardston landfill in Massachusetts) was measured using a frost measurement system. A thermistor probe measured the temperature at various depths. Although temperature measurements are important, soil resistivity measurements are required to accurately predict the freezing level, since soil resistivity increases greatly upon freezing. A conductivity probe measured the half-bridge voltage between conductivity rings and a ground rod. Data were collected in data loggers. The data collected from 1992--1996 showed that the frost level did not penetrate the paper sludge capping layer. Heavy snow cover throughout the winters decreased the depth of frost penetration by insulating the landfill. The high water content in the sludge also contributed to the lack of freezing.

    This Correction Action Investigation Plan contains the environmental sample collection objectives and the criteria for conducting site investigation activities at the Area 3 Landfill Complex, CAU No. 424, which is located at the Tonopah Test Range (TTR). The TTR, included in the Nellis Air Force Range, is approximately 255 kilometers (140 miles) northwest of Las Vegas, nevada. The CAU 424 is comprised of eight individual landfill sites that are located around and within the perimeter of the Area 3 Compound. Due to the unregulated disposal activities commonly associated with early landfill operations, an investigation will be conducted at each CAS to complete the following tasks: identify the presence and nature of possible contaminant migration from the landfills; determine the vertical and lateral extent of possible contaminant migration; ascertain the potential impact to human health and the environment; and provide sufficient information and data to develop and evaluate appropriate corrective action strategies for each CAS.

    The worldwide demand for potable water has been steadily growing and is projected to accelerate, driven by a continued population growth and industrialization of emerging countries. This growth is reflected in a recent market survey by the World Resources Institute, which shows a doubling in the installed capacity of seawater desalination plants every ten years. The production of desalinated water is energy intensive, requiring approximately 3-6 kWh/m3 of produced desalted water. At current U.S. water use rates, a dedicated 1000 MW power plant for every one million people would be required to meet our water needs with desalted water. Nuclear energy plants are attractive for large scale desalination application. The thermal energy produced in a nuclear plant can provide both electricity and desalted water without the production of greenhouse gases. A particularly attractive option for nuclear desalination is to couple a desalination plant with an advanced, modular, passively safe reactor design. The use of small-to-medium sized nuclear power plants allows for countries with smaller electrical grid needs and infrastructure to add new electrical and water capacity in more appropriate increments and allows countries to consider siting plants at a broader number of distributed locations. To meet these needs, a modified version of the International Reactor Innovative and Secure (IRIS) nuclear power plant design has been developed for the cogeneration of electricity and desalted water. The modular, passively safe features of IRIS make it especially well adapted for this application. Furthermore, several design features of the IRIS reactor will ensure a safe and reliable source of energy and water even for countries with limited nuclear power experience and infrastructure. The IRIS-D design utilizes low-quality steam extracted from the low-pressure turbine to boil seawater in a multi-effect distillation desalination plant. The desalination plant is based on the horizontal

    Waste Processors Management, Inc. (WMPI), along with its subcontractors Texaco Power & Gasification (now ChevronTexaco), SASOL Technology Ltd., and Nexant Inc. entered into a Cooperative Agreement DE-FC26-00NT40693 with the U. S. Department of Energy (DOE), National Energy Technology Laboratory (NETL) to assess the techno-economic viability of building an Early Entrance Co-Production Plant (EECP) in the United States to produce ultra clean Fischer-Tropsch (FT) transportation fuels with either power or steam as the major co-product. The EECP design includes recovery and gasification of low-cost coal waste (culm) from physical coal cleaning operations and will assess blends of the culm with coal or petroleum coke. The project has three phases. Phase I is the concept definition and engineering feasibility study to identify areas of technical, environmental and financial risk. Phase II is an experimental testing program designed to validate the coal waste mixture gasification performance. Phase III updates the original EECP design based on results from Phase II, to prepare a preliminary engineering design package and financial plan for obtaining private funding to build a 5,000 barrel per day (BPD) coal gasification/liquefaction plant next to an existing co-generation plant in Gilberton, Schuylkill County, Pennsylvania. The current report covers the period performance from July 1, 2003 through September 30, 2003. The DOE/WMPI Cooperative Agreement was modified on May 2003 to expand the project team to include Shell Global Solutions, U.S. and Uhde GmbH as the engineering contractor. The addition of Shell and Uhde strengthen both the technical capability and financing ability of the project. Uhde, as the prime EPC contractor, has the responsibility to develop a LSTK (lump sum turnkey) engineering design package for the EECP leading to the eventual detailed engineering, construction and operation of the proposed concept.

    The Paducah Gaseous Diffusion Plant (PGDP) has operated captive landfills (both residential and construction/demolition debris) in accordance with the Commonwealth of Kentucky regulations since the early 1980s. Typical waste streams allowed in these landfills include nonhazardous industrial and municipal solid waste (such as paper, plastic, cardboard, cafeteria waste, clothing, wood, asbestos, fly ash, metals, and construction debris). In July 1992, the U.S. Environmental Protection Agency issued new requirements for the disposal of sanitary wastes in a {open_quotes}contained landfill.{close_quotes} These requirements were promulgated in the 401 Kentucky Administrative Record Chapters 47 and 48 that became effective 30 June 1995. The requirements for a new contained landfill include a synthetic liner made of high-density polyethylene in addition to the traditional 1-meter (3-foot) clay liner and a leachate collection system. A new landfill at Paducah would accept waste streams similar to those that have been accepted in the past. The permit for the previously existing landfills did not include radioactivity limits; instead, these levels were administratively controlled. Typically, if radioactivity was detected above background levels, the waste was classified as low-level waste (LLW), which would be sent off-site for disposal.

    The U.S. Environmental Protection Agency (EPA), in accordance with the RE-Powering America's Land initiative, selected the Johnson County Landfill in Shawnee, Kansas, for a feasibility study of renewable energy production. Citizens of Shawnee, city planners, and site managers are interested in redevelopment uses for landfills in Kansas that are particularly well suited for grid-tied solar photovoltaic (PV) installation. This report assesses the Johnson County Landfill for possible grid-tied PV installations and estimates the cost, performance, and site impacts of three different PV options: crystalline silicon (fixed tilt), crystalline silicon (single-axis tracking), and thin film (fixed tilt). Each option represents a standalone system that can be sized to use an entire available site area. In addition, the report outlines financing options that could assist in the implementation of a system. The feasibility of PV systems installed on landfills is highly impacted by the available area for an array, solar resource, operating status, landfill cap status, distance to transmission lines, and distance to major roads. The report findings are applicable to other landfills in the surrounding area.

    Highlights: > Follow-up of the emission of VOCs in a municipal waste pilot-scale cell during the acidogenesis and acetogenesis phases. > Study from the very start of waste storage leading to a better understanding of the decomposition/degradation of waste. > Comparison of the results obtained on the pilot-scale cell with those from 3 biogases coming from the same landfill site. > A methodology of characterization for the progression of the stabilization/maturation of waste is finally proposed. - Abstract: The emission of volatile organic compounds (VOCs) from municipal solid waste stored in a pilot-scale cell containing 6.4 tonnes of waste (storage facility which is left open during the first period (40 days) and then closed with recirculation of leachates during a second period (100 days)) was followed by dynamic sampling on activated carbon and analysed by GC-MS after solvent extraction. This was done in order to know the VOC emissions before the installation of a methanogenesis process for the entire waste mass. The results, expressed in reference to toluene, were exploited during the whole study on all the analyzable VOCs: alcohols, ketones and esters, alkanes, benzenic and cyclic compounds, chlorinated compounds, terpene, and organic sulphides. The results of this study on the pilot-scale cell are then compared with those concerning three biogases from a municipal waste landfill: biogas (1) coming from waste cells being filled or recently closed, biogas (2) from all the waste storage cells on site, and biogas (3) which is a residual gas from old storage cells without aspiration of the gas. The analysis of the results obtained revealed: (i) a high emission of VOCs, principally alcohols, ketones and esters during the acidogenesis; (ii) a decrease in the alkane content and an increase in the terpene content were observed in the VOCs emitted during the production of methane; (iii) the production of heavier alkanes and an increase in the average number of carbon

    Highlights: • Samples from multiple core drills were obtained from 4× landfill sites in the UK. • Each sample analysed for rare earth elements, critical metals and valuable metals. • Two stage microwave digestion method ensuring high yield. • High quantities of copper and aluminium were observed in the soil layers of landfill. • Across 4× landfills aluminium and copper present has a value of around $400 million. - Abstract: Rare earth elements (REEs), Platinum group metals (PGMs) and other critical metals currently attract significant interest due to the high risks of supply shortage and substantial impact on the economy. Their uses in many applications have made them present in municipal solid waste (MSW) and in commercial and industrial waste (C&I), since several industrial processes produce by-products with high content of these metals. With over 4000 landfills in the UK alone, the aim of this study was to assess the existence of these critical metals within landfills. Samples collected from four closed landfills in UK were subjected to a two-step acid digestion to extract 27 metals of interest. Concentrations across the four landfill sites were 58 ± 6 mg kg{sup −1} for REEs comprising 44 ± 8 mg kg{sup −1} for light REEs, 11 ± 2 mg kg{sup −1} for heavy REEs and 3 ± 1 mg kg{sup −1} for Scandium (Sc) and 3 ± 1.0 mg kg{sup −1} of PGMs. Compared to the typical concentration in ores, these concentrations are too low to achieve a commercially viable extraction. However, content of other highly valuable metals (Al and Cu) was found in concentrations equating to a combined value across the four landfills of around $400 million, which increases the economic viability of landfill mining. Presence of critical metals will mainly depend on the type of waste that was buried but the recovery of these metals through landfill mining is possible and is economically feasible only if additional materials (plastics, paper, metallic items and other) are

    Each person in the US produces approximately one ton of trash per year. The environmentally friendly municipal trash processing and recycling complex used for illustrative purposes in this paper is designed and sized to handle trash from typical municipalities ranging from 500,000 to 750,000 populations. This translates into a nominal 2,000 ton per day (TPD) facility. A typical component breakdown of municipal solid waste is shown in appendix A. The layout of the complex is shown in appendix B. Today`s municipal trash processing and recycling center should be designed to serve the needs of the municipality for at least the next 20 to 30 years. It should also be designed in such a way as to allow any new technology advancements to be added easily and in a cost effective manner to extend the useful service life of the facility almost indefinitely. 100% of the trash will be recycled. There will be no need for a dump, landfill, or disposal site at all. No curbside separation is required.

    Townsend, Aaron K.; Webber, Michael E.

    2012-07-15

    This study presents a novel integrated method for considering the economics of waste-to-energy (WTE) facilities with priced greenhouse gas (GHG) emissions based upon technical and economic characteristics of the WTE facility, MSW stream, landfill alternative, and GHG emissions policy. The study demonstrates use of the formulation for six different policy scenarios and explores sensitivity of the results to ranges of certain technical parameters as found in existing literature. The study shows that details of the GHG emissions regulations have large impact on the levelized cost of energy (LCOE) of WTE and that GHG regulations can either increase or decrease the LCOE of WTE depending on policy choices regarding biogenic fractions from combusted waste and emissions from landfills. Important policy considerations are the fraction of the carbon emissions that are priced (i.e. all emissions versus only non-biogenic emissions), whether emissions credits are allowed due to reducing fugitive landfill gas emissions, whether biogenic carbon sequestration in landfills is credited against landfill emissions, and the effectiveness of the landfill gas recovery system where waste would otherwise have been buried. The default landfill gas recovery system effectiveness assumed by much of the industry yields GHG offsets that are very close to the direct non-biogenic GHG emissions from a WTE facility, meaning that small changes in the recovery effectiveness cause relatively larger changes in the emissions factor of the WTE facility. Finally, the economics of WTE are dependent on the MSW stream composition, with paper and wood being advantageous, metal and glass being disadvantageous, and plastics, food, and yard waste being either advantageous or disadvantageous depending upon the avoided tipping fee and the GHG emissions price.

    Surface covers to control water infiltration to waste buried in landfills will be the remediation alternative of choice for most hazardous and sanitary landfills operated by the Department of Defense. Although surface covers are the least expensive method of remediation for landfills, they can still be expensive solutions. Conventional wisdom suggests that landfill capping technology is well developed as evidenced by the availability of EPA guidance for designing and constructing what has become known as the {open_quotes}RCRA Cap{close_quotes}. In practice, however, very little testing of the RCRA cap, or any other design, has been done to evaluate how effective these designs are in limiting infiltration of water into waste. This paper describes a low cost alternative to the {open_quotes}RCRA Cap{close_quotes} that is being evaluated at Marine Corps Base Hawaii (MCBH) Kaneohe Bay. This study uses an innovative, simple and inexpensive concept to manipulate the fate of water falling on a landfill. The infiltration of water through the cap will be controlled by combining the evaporative forces of vegetation to remove soil water, with engineered structures that limit infiltration of precipitation into the soil. This approach relies on diverting enough of the annual precipitation to runoff, so that the water that does infiltrate into the soil can easily be removed by evapotranspiration.

The scope of the study excluded waste units that manage CCWs in active or abandoned coal mines. The EPA identified the following three areas of interest: (1) Recent and current CCW industry surface disposal management practices, (2) State regulatory requirements for CCW management, and (3) Implementation of State requirements (i.e., the extent to which States grant or deny operator requests to waive or vary regulatory requirements and the rationales for doing so). DOE and the EPA obtained data on recent and current disposal practices from a questionnaire that the Utility Solid Waste Activities Group (USWAG) distributed to its members that own or operate coal-fired power plants. USWAG, formed in 1978, is responsible for addressing solid and hazardous waste issues on behalf of the utility industry. It is an informal consortium of approximately 80 utility operating companies, the Edison Electric Institute (EEI), the National Rural Electric Cooperative Association (NRECA), the American Public Power Association (APPA), and the American Gas Association (AGA). EEI is the principal national association of investor-owned electric power and light companies. NRECA is the national association of rural electric cooperatives. APPA is the national association of publicly owned electric utilities. AGA is the national association of natural gas utilities. Together, USWAG member companies and trade associations represent more than 85% of the total electric generating capacity of the United States and service more than 95% of the nation's consumers of electricity. To verify the survey findings, the EPA also asked State regulators from nine selected States that are leading consumers of coal for electricity generation for information on disposal units that may not have been covered in the USWAG survey.

    Large amounts of acidic petroleum refinery wastes (PRW) have been buried in landfills during the period 1930-1950. Many of the compounds IN PRW have not identified. Organosulfur compounds constitute an important fraction of these wastes, and are significant in site closure planning and cleanup operations. Some are difficult analytes because they undergo facile conversions during standard methods of sample preparation and analysis. A mild liquid chromatographic method using cyanopropyl and octadecyl stationary phases and a modified hexane mobile phase was found to separate PRW into five major groups, two of which contain sulfur compounds. GC/MS analysis of collected HPLC fractions identified over 80% of the compounds present. Wastes from three different landfills used in the period 1940-1950 show major similarities, but differ in relative composition. Implications for remediation of PRW in these and similar landfills designated as Superfund sites are discussed.

    This calculation was to seismically evaluate Landfill IV at Y-12 as required by Tennessee Rule 1200-1-7-04(2) for seismic impact zones. The calculation verifies that the landfill meets the seismic requirements of the Tennessee Division of Solid Waste, ``Earthquake Evaluation Guidance Document.`` The theoretical displacements of 0.17 in. and 0.13 in. for the design basis earthquake are well below the limiting seimsic slope stability design criteria. There is no potential for liquefaction due to absence of chohesionless soils, or for loss or reduction of shear strength for the clays at this site as result of earthquake vibration. The vegetative cover on slopes will most likely be displaced and move during a large seismic event, but this is not considered a serious deficiency because the cover is not involved in the structural stability of the landfill and there would be no release of waste to the environment.

    The US Department of Energy (DOE) is proposing to install a wet ash handling system to dewater bottom ash from the coal-fired steam plant at its Y-12 Plant and to construct a new landfill for disposal of industrial wastes, including the dewatered bottom ash. The DOE operates three major facilities on its Oak Ridge Reservation (ORR). Operation of these facilities results in the production of a variety of nonhazardous, nonradioactive solid wastes (approximately 300 m{sup 3} per day, compacted) including sanitary wastes, common industrial wastes and construction debris. At the current rate of use, this existing landfill will be filled within approximately 18 months, and more space is urgently needed. In an effort to alleviate this problem, DOE and WMD management propose to create additional landfill facilities at a nearby site. The potential environmental impacts associated with this proposed action are the subject of this environmental assessment (EA).

    One important environmental issue facing Northwest Indiana and park management at Indiana Dunes National Lakeshore (INOU) is the contamination of water, sediment and biota by persistent toxic substances. Aquatic plant communities were used to evaluate the water/organismal quality of the Grand Calumet Lagoons and two dunal ponds (pannes) at Gary, Indiana, which are partially located in the Miller Woods Unit of INDU. The lagoon is divided into several areas, the USX Lagoon is located between sections of a large industrial landfill (steel slag and other material). The Marquette Lagoon is located further away from the landfill and tends to be upgradient from the landfill. The West Panne (WP) is located next to the landfill, while the East Panne (EP) is separated from the landfill and the WP by a high dune ridge. Plant populations shift toward fewer submergent aquatics, with a higher abundance of tolerant taxa in the western section of the USX Lagoon. These differences are supported by cluster analysis. Heavy metals in root tissue of Scirpus americanus and other plant species from the pannes were significantly higher than those found in shoots. Shoot tissue metal levels in plants collected from the lagoons were higher than root tissue metal levels. The WP site has the most elevated tissue metal levels for most metals assayed, while the EP site shows similar contaminant levels. The plant distributions observed and tissue metal concentrations measured suggest that INDU`s aquatic plant community has been affected by the industrial landfill and that there exists a hydrological connection between the ponds.

    A method of measuring a parameter of a landfill including a cap, without passing wires through the cap, includes burying a sensor apparatus in the landfill prior to closing the landfill with the cap; providing a reader capable of communicating with the sensor apparatus via radio frequency (RF); placing an antenna above the barrier, spaced apart from the sensor apparatus; coupling the antenna to the reader either before or after placing the antenna above the barrier; providing power to the sensor apparatus, via the antenna, by generating a field using the reader; accumulating and storing power in the sensor apparatus; sensing a parameter of the landfill using the sensor apparatus while using power; and transmitting the sensed parameter to the reader via a wireless response signal. A system for measuring a parameter of a landfill is also provided.

    These guidelines were designed to assist National Rural Electric Cooperative Association staff and consultants involved in the implementation of Sections 201 and 210 of the Public Utilities Regulatory Policies Act (PURPA). The guidelines were structured to meet anticipated use as: a self-contained legal, technical and economic reference manual helpful in dealing with small power producers and cogenerators; a roadmap through some of the less obvious obstacles encountered by utilities interacting with small power producers and cogenerators; a starting point for those utilities who have not yet formulated specific policies and procedures, nor developed rates for purchasing power from small power producers and cogenerators; a discussion vehicle to highlight key issues and increase understanding in workshop presentations to rural electric cooperatives; and an evolutionary tool which can be updated to reflect changes in the law as they occur. The chapters in these Guidelines contain both summary information, such as compliance checklists, and detailed information, such as cost rate calculations, on regulatory requirements, operational considerations, and rate considerations. The appendices contain more specific material, e.g. rural electric cooperative sample policy statements. (LCL)

    In this project, two key issues were addressed to show the feasibility of electrochemical partial oxidation (EPOx) in a SOFC. First, it was demonstrated that SOFCs can reliably operate directly with natural gas. These results are relevant to both direct-natural-gas SOFCs, where the aim is solely electrical power generation, and to EPOx. Second, it must be shown that SOFCs can work effectively as partial oxidation reactors, i.e, that they can provide high conversion efficiency of natural gas to syngas. The results of this study in both these areas look extremely promising. The main results are summarized briefly: (1) Stability and coke-free direct-methane SOFC operation is promoted by the addition of a thin porous inert barrier layer to the anode and the addition of small amounts of CO{sub 2} or air to the fuel stream; (2) Modeling results readily explained these improvements by a change in the gas composition at the Ni-YSZ anode to a non-coking condition; (3) The operation range for coke-free operation is greatly increased by using a cell geometry with a thin Ni-YSZ anode active layer on an inert porous ceramic support, i.e., (Sr,La)TiO{sub 3} or partially-stabilized zirconia (in segmented-in-series arrays); (4) Ethane and propane components in natural gas greatly increase coking both on the SOFC anode and on gas-feed tubes, but this can be mitigated by preferentially oxidizing these components prior to introduction into the fuel cell, the addition of a small amount of air to the fuel, and/or the use of ceramic-supported SOFC; (5) While a minimum SOFC current density was generally required to prevent coking, current interruptions of up to 8 minutes yielded only slight anode coking that caused no permanent damage and was completely reversible when the cell current was resumed; (6) Stable direct-methane SOFC operation was demonstrated under EPOx conditions in a 350 h test; (7) EPOx operation was demonstrated at 750 C that yielded 0.9 W/cm{sup 2} and a syngas

    Liquefied natural gas (LNG) is being developed as a heavy vehicle fuel. The reason for developing LNG is to reduce our dependency on imported oil by eliminating technical and costs barriers associated with its usage. The U.S. Department of Energy (DOE) has a program, currently in its third year, to develop and advance cost-effective technologies for operating and refueling natural gas-fueled heavy vehicles (Class 7-8 trucks). The objectives of the DOE Natural Gas Vehicle Systems Program are to achieve market penetration by reducing vehicle conversion and fuel costs, to increase consumer acceptance by improving the reliability and efficiency, and to improve air quality by reducing tailpipe emissions. One way to reduce fuel costs is to develop new supplies of cheap natural gas. Significant progress is being made towards developing more energy-efficient, low-cost, small-scale natural gas liquefiers for exploiting alternative sources of natural gas such as from landfill and remote gas sites. In particular, the DOE program provides funds for research and development in the areas of; natural gas clean up, LNG production, advanced vehicle onboard storage tanks, improved fuel delivery systems and LNG market strategies. In general, the program seeks to integrate the individual components being developed into complete systems, and then demonstrate the technology to establish technical and economic feasibility. The paper also reviews the importance of cryogenics in designing LNG fuel delivery systems.

    During 1984, the environmental monitoring program was continued at the former Middlesex Sampling Plant (MSP) and former Middlesex Municipal Landfill (MML) sites, located in the Borough of Middlesex, New Jersey. The sites are part of the Formerly Utilized Sites Remedial Action Program (FUSRAP), a United States Department of Energy (DOE) program to decontaminate or otherwise control sites where low-level radioactive contamination remains from the early years of the nation's atomic energy program. The environmental monitoring program is carried out by Bechtel National, Inc., Program Management Contractor for FUSRAP. The monitoring program at the MSP and MML measures the uranium and radium concentrations in surface and groundwater, the radon gas concentrations in air, and external gamma radiation exposure rates. Potential radiation doses to the public are also calculated. All environmental samples collected are analyzed to determine compliance with applicable environmental quality standards. DOE Order 5480.1A, Chapter XI, provides applicable Concentration Guide (CG) limits for radionuclides in controlled and uncontrolled areas. During 1984, average annual concentrations of uranium and radium-226 in groundwater and surface waters monitored for both the MSP and MML remained below the DOE CG for uncontrolled areas. Annual average radon levels in air at both the MSP and MML were below the CG for uncontrolled areas. External gamma monitoring in 1984 showed all monitoring locations at both sites reporting gamma exposure rates below DOE Radiation Protection Standards. All radiation doses to the public were within DOE standards and consistent with 1983 exposure rates. 13 refs., 10figs., 13 tabs.

The system was initially operated under anaerobic conditions for 366 days, after which the yard waste was aerated for an additional 191 days. Off gas generated from the aerobic stage was treated by biofilters. Net energy recovery was 84.3 MWh, or 46 kWh per million metric tons of wet waste (as received), and the biochemical methane potential of the treated waste decreased by 83% during the two-stage operation. The average removal efficiencies of volatile organic compounds and non-methane organic compounds in the biofilters were 96-99% and 68-99%, respectively.

    The La Paz County Regional Landfill is a 65 hectare (160 acre) municipal waste site located near the western border of Arizona between the cities of Parker and Quartzsite. The site is operated under a public/private partnership between the County of La Paz and Browning-Ferris Industries, Inc. (BFI). The County owns the landfill and infrastructure and BFI is responsible for facility improvements, environmental compliance, and daily operations. Following the initial permitting and construction of the first landfill cell, a value engineering review was conducted on the site design and permit requirements. Based on this review, substantial cost saving opportunities were identified. In order to implement the value engineering ideas, the site permit was modified and a new Solid Waste Facilities Plan was Submitted to the Arizona Department of Environmental Quality. This paper discusses the value engineering modifications that were conducted, the revisions to the permits, and the relative cost savings that were realized. The areas addressed include the liner system design, closure design, disposal capacity, and operations plan. Through the use of alternative liners a cost savings of well over 50 percent (as compared to the original permit) will be realized over the life of the landfill.

    The Fresh Kills Landfill, located in Staten Island, New York, serves as the repository of all municipal solid waste from the five boroughs of New York City. Because of the existence of compressible soils under most of the filling areas and the urban environment surrounding the landfill, considerable importance is being placed on the relationship between filling operations and the stability of the landfill. As a result of this concern and to address Order on Consent requirements, a program of geotechnical site characterizations, stability analyses, and design and implementation of a geotechnical instrumentation program was undertaken. Geotechnical instruments have been installed within the refuse fill and foundation soils to monitor both the magnitude and rate of change of pore pressure, lateral and vertical movements, and temperature. This paper presents an overview of the subsurface conditions, the overall instrumentation plan for assessing the landfill stability, a description of the various instruments, the performance of these instruments to date, an overview of the collected measurements, and a description of how these measurements are used to monitor the stability.

    1995-12-31

    Several monitoring wells at a landfill site were sampled for water quality parameters to determine the nature of groundwater contamination. The landfill, located beneath a limestone and dolomitic bedrock, has been used for about 20 years for trash and garbage disposal. The monitoring parameters include major cations and anions, as well as iron, manganese, arsenic, and other parameters measured in the field to characterize the subsurface conditions. Groundwater samples collected near the landfill and downgradient locations had higher levels of iron, manganese, arsenic, alkalinity, hardness than those samples from an upgradient well. The downgradient and on-site samples were also more acidic and turbid, The dissolved oxygen data tend to suggest reducing conditions in the leachate environment. The elevated groundwater concentrations of the three metals, especially iron, were most probably caused by the acidity generated by carbon dioxide and organic acids released from microbial degradation of organic compounds dumped into the landfill. The acidic pH led to the dissolution of iron, manganese, and arsenic bearing mineral phases. The buffering reactions of limestone and dolomite to neutralize the acidic degradation products increased the hardness cations, Ca{sup +2} and Mg{sup +2}. Inorganic speciation modeling indicates that iron, manganese, and arsenic predominantly exist as Fe {sup +2}, Mn{sup +2}, and H{sub 3}AsO{sub 3}. The possible presence of organic complexes of iron was discussed, but could be modeled due to lack of appropriate equilibrium constant data.

    The goal of disposing of radioactive and hazardous waste in shallow landfills is to reduce risk to human health and to the environment by isolating contaminants until they no longer pose a hazard. In order to achieve this, the performance of a landfill cover design without an engineered barrier (Conventional Design) was compared with three designs containing either a hydraulic barrier (EPA Design) or a capillary barrier (Loam and Clay Loam Capillary Barrier Designs). Water balance parameters were measured since 1991 at six-hour intervals for four different landfill cover designs in 1.0- by 10.0-m plots with downhill slopes of 5, 10, 15, and 25%. Whereas runoff generally accounted for only 2-3% of the precipitation losses on these designs, similar values for evapotranspiration ranged from 86% to 91%, with increased evapotranspiration occurring with increases in slope. Consequently, interflow and seepage usually decreased with increasing slope for each landfill cover design. Seepage consisted of up to 10% of the precipitation on the Conventional Design, whereas the hydraulic barrier in the EPA Design effectively controlled seepage at all slopes, and both of the capillary designs worked effectively to eliminate seepage at the higher slopes.

    Waste Processors Management, Inc. (WMPI), along with its subcontractors entered into a Cooperative Agreement with the US Department of Energy (DOE) and the National Energy Technology Laboratory (NETL) to assess the techno-economic viability of building an Early Entrance Co-Production Plant (EECP) in the US to produce ultra clean Fischer-Tropsch (FT) transportation fuels with either power or steam as the major co-product. The EECP design includes recovery and gasification of low-cost coal waste (culm) from physical coal cleaning operations and will assess blends of the culm with coal or petroleum coke. The project has three phases. Phase 1 is the concept definition and engineering feasibility study to identify areas of technical, environmental and financial risk. Phase 2 is an experimental testing program designed to validate the coal waste mixture gasification performance. Phase 3 updates the original EECP design based on results from Phase 2, to prepare a preliminary engineering design package and financial plan for obtaining private funding to build a 5,000 barrel per day (BPD) coal gasification/liquefaction plant next to an existing co-generation plant in Gilberton, Schuylkill County, Pennsylvania. The current report covers the period performance from April 1, 2002 through June 30, 2002.

    In February of 1980 the Federal Energy Regulatory Commission (FERC) promulgated a set of rules that were to commence the implementation process of Section 210 of the Public Utility Regulatory Policies Act of 1978 (PURPA). Of particular interest to economists are the pricing provisions in the rules that pertain to integrating dispersed sources of electric power generation into conventional electric utility systems. The full avoided cost pricing provision couples a utility mandate to purchase power from qualified dispersed facilities (cogenerators, wind power, small hydro facilities, etc., hereafter denoted QFs) with the requirement that the price the utility pays for such purchases be equal to the full extent of the cost it avoids by not generating the power itself. The simultaneous purchase and sale billing scheme requires a utility to purchase the gross power output of a QF at the full avoided cost rate and simultaneously sell back to the QF its power requirement on the applicable retail tariff. Theoretical investigation of these two provisions reveals that, properly defined, they are consistent with improving economic signals with respect to electricity generation.

    We have experimentally observed the behaviour of cogenerated dusts in unmagnetized plasma produced using a bipolar pulsed dc power supply. In this experiment, the dust particles have been generated through sputtering of graphite cathode and were stratified between two electrodes. This stratification of dust clouds has obtained at a typical range of plasma parameters, namely, 650 V (peak-to-peak) with 0.2 mbar pressure. In above condition, we detected the Taylor-like instability at the interface of two dusty clouds with different densities. A very less dust density (void like) region inside the lesser dust density portion is also noted. Again, it has been observed that a self excited dust density wave propagates towards the higher density dust fluid inside the system as well as a stationary band structure of thin multiple layers of dust particles when we apply a higher voltage (750 V peak-to-peak). The wavelength, phase velocity, and frequency of the excited wave have also been estimated.

Black-Right-Pointing-Pointer Address the issues and operational conditions for application in leachate treatment. - Abstract: In today's context of waste management, landfilling of Municipal Solid Waste (MSW) is considered to be one of the standard practices worldwide. Leachate generated from municipal landfills has become a great threat to the surroundings as it contains high concentration of organics, ammonia and other toxic pollutants. Emphasis has to be placed on the removal of ammonia nitrogen in particular, derived from the nitrogen content of the MSW and it is a long term pollution problem in landfills which determines when the landfill can be considered stable. Several biological processes are available for the removal of ammonia but novel processes such as the Single Reactor System for High Activity Ammonia Removal over Nitrite (SHARON) and Anaerobic Ammonium Oxidation (ANAMMOX) process have great potential and several advantages over conventional processes. The combined SHARON-ANAMMOX process for municipal landfill leachate treatment is a new, innovative and significant approach that requires more research to identify and solve critical issues. This review addresses the operational parameters, microbiology, biochemistry and application of both the processes to remove ammonia from leachate.

    Highlights: • Quantifies the different waste streams delivered at the landfill. • Evaluates the amount of potential waste products that enters into the reverse cycle. • Drawing out the reverse logistics activities from Kampala City to Kiteezi landfill. • Identify the storage, collection and transportation mechanisms of products to the various destinations; and finally. • The study suggests efficient measures to improve reverse logistics system. - Abstract: The rapid growing population and high urbanisation rates in Sub-Saharan Africa has caused enormous pressure on collection services of the generated waste in the urban areas. This has put a burden on landfilling, which is the major waste disposal method. Waste reduction, re-use and recycling opportunities exist but are not fully utilized. The common items that are re-used and re-cycled are plastics, paper, aluminum, glass, steel, cardboard, and yard waste. This paper develops an overview of reverse logistics at Kiteezi landfill, the only officially recognised waste disposal facility for Kampala City. The paper analyses, in details the collection, re-processing, re-distribution and final markets of these products into a reversed supply chain network. Only 14% of the products at Kiteezi landfill are channeled into the reverse chain while 63% could be included in the distribution chain but are left out and disposed of while the remaining 23% is buried. This is because of the low processing power available, lack of market value, lack of knowledge and limited value addition activities to the products. This paper proposes possible strategies of efficient and effective reverse logistics development, applicable to Kampala City and other similar cities.

  1. Modeling of leachate generation from MSW landfills by a 2-dimensional 2-domain approach

    SciTech Connect (OSTI)

    Fellner, Johann

    2010-11-15

    The flow of water through Municipal Solid Waste (MSW) landfills is highly non-uniform and dominated by preferential pathways. Thus, concepts to simulate landfill behavior require that a heterogeneous flow regime is considered. Recent models are based on a 2-domain approach, differentiating between channel domain with high hydraulic conductivity, and matrix domain of slow water movement with high water retention capacity. These models focus on the mathematical description of rapid water flow in channel domain. The present paper highlights the importance of water exchange between the two domains, and expands the 1-dimensional, 2-domain flow model by taking into account water flows in two dimensions. A flow field consisting of a vertical path (channel domain) surrounded by the waste mass (matrix domain) is defined using the software HYDRUS-2D. When the new model is calibrated using data sets from a MSW-landfill site the predicted leachate generation corresponds well with the observed leachate discharge. An overall model efficiency in terms of r{sup 2} of 0.76 was determined for a simulation period of almost 4 years. The results confirm that water in landfills follows a preferential path way characterized by high permeability (K{sub s} = 300 m/d) and zero retention capacity, while the bulk of the landfill (matrix domain) is characterized by low permeability (K{sub s} = 0.1 m/d) and high retention capacity. The most sensitive parameters of the model are the hydraulic conductivities of the channel domain and the matrix domain, and the anisotropy of the matrix domain.

    Highlights: • LATS has been effective to achieve a reduction of the amount of landfilled waste. • LATS has been one of the few environmental instruments for waste management with a cap and trade methodology. • LATS has achieved to increase recycling of the biodegradable and other waste fractions. - Abstract: The Landfill Allowance Trading Scheme (LATS) is one of the main instruments used in England to enforce the landfill diversion targets established in the Directive 1999/31/EC of the European Parliament and of the Council of 26 April 1999 on the landfill of waste (Landfill Directive). Through the LATS, biodegradable municipal waste (BMW) allowances for landfilling are allocated to each local authority, otherwise known as waste disposal authorities (WDAs). The quantity of landfill allowances received is expected to decrease continuously from 2005/06 to 2019/20 so as to meet the objectives of the Landfill Directive. To achieve their commitments, WDAs can exchange, buy, sell or transfer allowances among each other, or may re-profile their own allocation through banking and/or borrowing. Despite the goals for the first seven years – which included two target years (2005/06 and 2009/10) – being widely achieved (the average allocation of allowances per WDA was 22.9% higher than those finally used), market activity among WDAs was high and prices were not very stable. Results in terms of waste reduction and recycling levels have been satisfactory. The reduction of BMW landfilled (in percentage) was higher during the first seven years of the LATS period (2005/06–2011/12) (around 7% annually) than during the previous period (2001/02–2004/05) (4.2% annually). Since 2008, the significance of the LATS diminished because of an increase in the rate of the UK Landfill Tax. The LATS was suppressed after the 2012/13 target year, before what it was initially scheduled. The purpose of this paper is to describe the particularities of the LATS, analyse its performance as

    In field studies conducted for the Electric Power Research Institute by the University of Washington (1978) and the University of Idaho (1979), 13 gas samples from sludge storage sites at coal-burning power plants were analyzed by wall-coated open-tube cryogenic capillary-column gas chromatography with a sulfur-selective flame-photometric detector. Hydrogen sulfide, carbonyl sulfide, dimethyl sulfide, carbon disulfide, and dimethyl disulfide were identified in varying concentrations and ratios in the emissions from both operating sludge ponds and landfills and from FGD sludge surfaces that had been stored in the open for 3-32 mo or longer. Other sulfur compounds, probably propanethiols, were found in emissions from some sludges. Chemical ''stabilization/fixation'' sulfate-sulfite ratio, sludge water content, and temperature were the most significant variables controlling sulfur gas production. The average sulfur emissions from each of the 13 FGD storage sites ranged from 0.01 to 0.26 g/sq m/yr sulfur.

All aspects have been analyzed from the manpower and equipment requirements at the landfill to the operational impacts felt at the LCSWMA Resource Recovery Facility (RRF) where the material is delivered for processing. Characteristics of the reclaimed refuse and soil recovered from trommeling operations are discussed as are results of air monitoring performed at the landfill excavation site and the RRF. The report also discusses the energy value of the reclaimed material and compares this value with those obtained for significantly older reclaimed waste streams. The effects of waste age on the air emissions and ash residue quality at the RRF are also provided. The report concludes by summarizing the project benefits and provides recommendations for other landfill reclamation operations and areas requiring further research.

    This report addresses low-level waste disposal operations at the Idaho Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) Disposal Facility (ICDF) landfill from the start of operations in Fiscal Year 2003 through Fiscal Year 2008. The ICDF was authorized in the Operable Unit 3-13 Record of Decision for disposal of waste from the Idaho National Laboratory Site CERCLA environmental restoration activities. The ICDF has been operating since 2003 in compliance with the CERCLA requirements and the waste acceptance criteria developed in the CERCLA process. In developing the Operable Unit 3-13 Record of Decision, U.S. Department of Energy Order (DOE) 435.1, 'Radioactive Waste Management', was identified as a 'to be considered' requirement for the ICDF. The annual review requirement under DOE Order 435.1 was determined to be an administrative requirement and, therefore, annual reviews were not prepared on an annual basis. However, the landfill has been operating for 5 years and, since the waste forms and inventories disposed of have changed from what was originally envisioned for the ICDF landfill, the ICDF project team has decided that this annual review is necessary to document the changes and provide a basis for any updates in analyses that may be necessary to continue to meet the substantive requirements of DOE Order 435.1. For facilities regulated under DOE Order 435.1-1, U.S. DOE Manual 435.1-1, 'Radioactive Waste Management', IV.P.(4)(c) stipulates that annual summaries of low-level waste disposal operations shall be prepared with respect to the conclusions and recommendations of the performance assessment and composite analysis. Important factors considered in this review include facility operations, waste receipts, and results from monitoring and research and development programs. There have been no significant changes in operations at the landfill in respect to the disposal geometry, the verification of waste characteristics, and the

    Deregulation and liberalization are changing the global energy-markets. At the same time innovative technologies are introduced in the electricity industry; often as a requirement from the upcoming Digital Society. Energy solutions for the future are more seen as a mix of energy-sources for generation-, transmission- and distribution energy-services. The Internet Energy-web based 'Virtual' enterprises are coming up and will gradually change our society. It the fast changing world we have to realize that there will be less time to look for the adequate solutions to anticipate on global developments and the way they will influence our own societies. Global population may reach 9 billion people by 2030; this will put tremendous pressure on energy-, water- and food supply in the global economy. It is time to think about some major issues as described below and come up with the right answers. These are needed on very short term to secure a humane global economic growth and the sustainable global environment. The DOE (Department of Energy - USA) has started the Generation IV initiative for the new generation of nuclear reactors that must lead to much better safety, economics and public acceptance the new reactors. The SGR (Simplified Gas-cooled Reactor) is being proposed as a Generation IV modular nuclear reactor, using graphite pebbles as fuel, whereby an attempt has been made to meet all the DOE requirements, to be used for future nuclear reactors. The focus in this paper is on the changing and emerging global energy-markets and shows some relevant criteria to the nuclear industry and how we can anticipate with improved and new designs towards the coming Digital Society.

    1994-01-01

    BPA is considering whether to transfer (wheel) electrical power from a proposed privately-owned, combustion-turbine electrical generation plant in Oregon. The plant would be fired by natural gas and would use combined-cycle technology to generate up to 440 average megawatts (aMW) of energy. The plant would be developed, owned, and operated by Portland General Electric Company (PGE). The project would be built in eastern Oregon, just east of the City of Boardman in Morrow County. The proposed plant would be built on a site within the Port of Morrow Industrial Park. The proposed use for the site is consistent with the County land use plan. Building the transmission line needed to interconnect the power plant to BPA`s transmission system would require a variance from Morrow County. BPA would transfer power from the plant to its McNary-Slatt 500-kV transmission line. PGE would pay BPA for wheeling services. Key environmental concerns identified in the scoping process and evaluated in the draft Environmental Impact Statement (DEIS) include these potential impacts: (1) air quality impacts, such as emissions and their contributions to the {open_quotes}greenhouse{close_quotes} effect; (2) health and safety impacts, such as effects of electric and magnetic fields, (3) noise impacts, (4) farmland impacts, (5) water vapor impacts to transportation, (6) economic development and employment impacts, (7) visual impacts, (8) consistency with local comprehensive plans, and (9) water quality and supply impacts, such as the amount of wastewater discharged, and the source and amount of water required to operate the plant. These and other issues are discussed in the DEIS. The proposed project includes features designed to reduce environmental impacts. Based on studies completed for the DEIS, adverse environmental impacts associated with the proposed project were identified, and no evidence emerged to suggest that the proposed action is controversial.

    In addition to being cost effective, very small nuclear power plants with static energy conversion could meet the needs and the energy mix in underdeveloped countries and remote communities, which may include electricity, residential and industrial space heating, seawater desalination, and/or high temperature process heat or steam for industrial uses. These plants are also an attractive option in naval, marine, and undersea applications, when the absence of a sound signature is highly desirable. An Analysis is performed of Gas Cooled Reactor (CGR) and Liquid Metal Cooled Reactor (LMR), very small nuclear power plants with static energy conversion, using a combination of options. These include Alkali Metal Thermal-to-Electric Converters (AMTECs) and both single segment and segmented thermoelectric converters. The total energy utilization of these plants exceeds 88%. It includes the fraction of the reactor's thermal power converted into electricity and delivered to the Grid at 6.6 kVA and those used for residential and industrial space heating at {approx}370 K, seawater desalination at 400 K, and/or high temperature process heat or steam at {approx}850 K. In addition to its inherently high reliability, modularity, low maintenance and redundancy, static energy conversion used in the present study could deliver electricity to the Grid at a net efficiency of 29.5%. A LMR plant delivers 2-3 times the fraction of the reactor thermal power converted into electricity in a GCR plant, but could not provide for both seawater desalination and high temperature process heat/steam concurrently, which is possible in GCR plants. The fraction of the reactor's thermal power used for non-electrical power generation in a GCR plant is {approx} 10 - 15% higher than in a LMR plant. (authors)

    1993-11-01

    In 1989, the US Geological Survey and Cornell University, in cooperation with the New York State Energy Research and Development Authority and the Tompkins County Solid Waste Department, began a three-year study at a municipal solid-waste landfill near Ithaca, New York, to test the effectiveness of leachate treatment with constructed wetlands and to examine the associated treatment processes. Specific objectives of the study were to examine: treatment efficiency as function of substrate composition and grain size, degree of plant growth, and seasonal changes in evapotranspiration rates and microbial activity; effects of leachate and plant growth on the hydraulic characteristics of the substrate; and chemical, biological, and physical processes by which nutrients, metals, and organic compounds are removed from leachate as it flows through the substrate. A parallel study at a municipal solid-waste landfill near Fenton, New York was conducted by researchers at Cornell University, Ithaca College, and Hawk Engineering (Trautmann and others, 1989). Results are described.

    The Ardeer Landfill site at ICI Explosives factory on the west coast of Scotland had been a repository for waste from the site for 40 years. In order to safeguard the local environment ICI Explosives, with approval of Local Authorities and the Clyde River Purification Board put into action a programme of investigation and planning which culminated in the in-situ treatment of 10,000 m3 of waste within the landfill by a deep mixing method using the {open_quotes}Colmix{close_quotes} system. The paper describes in varying degrees of detail the remediation from investigation to the execution of the in-situ stabilisation and presents the post construction monitoring results.

    Highlights: • Longitudinal data analysis using a mixed-effects regression model. • Dataset consisted of a total of 1402 samples from 101 closed municipal landfills. • Target analytes and classes generally showed predictable degradation trends. • Validates historical studies focused on macro organic indicators such as BOD. • BOD can serve as “gateway” indicator for planning leachate management. - Abstract: Landfill functional stability provides a target that supports no environmental threat at the relevant point of exposure in the absence of active control systems. With respect to leachate management, this study investigates “gateway” indicators for functional stability in terms of the predictability of leachate characteristics, and thus potential threat to water quality posed by leachate emissions. Historical studies conducted on changes in municipal solid waste (MSW) leachate concentrations over time (longitudinal analysis) have concentrated on indicator compounds, primarily chemical oxygen demand (COD) and biochemical oxygen demand (BOD). However, validation of these studies using an expanded database and larger constituent sets has not been performed. This study evaluated leachate data using a mixed-effects regression model to determine the extent to which leachate constituent degradation can be predicted based on waste age or operational practices. The final dataset analyzed consisted of a total of 1402 samples from 101 MSW landfills. Results from the study indicated that all leachate constituents exhibit a decreasing trend with time in the post-closure period, with 16 of the 25 target analytes and aggregate classes exhibiting a statistically significant trend consistent with well-studied indicators such as BOD. Decreasing trends in BOD concentration after landfill closure can thus be considered representative of trends for many leachate constituents of concern.

    This report provides results from the first year of this three-year project to develop dilution measurement technology for characterizing PM2.5 (particles with aerodynamic diameter smaller than 2.5 micrometers) and precursor emissions from stationary combustion sources used in oil, gas and power generation operations. Detailed emission rate and chemical speciation test results for a refinery gas-fired process heater and plans for cogeneration gas turbine tests and pilot-scale tests are presented. Tests were performed using a research dilution sampling apparatus and traditional EPA methods to compare PM2.5 mass and chemical speciation. Test plans are presented for a gas turbine facility that will be tested in the fourth quarter of 2002. A preliminary approach for pilot-scale tests is presented that will help define design constraints for a new dilution sampler design that is smaller, lighter, and less costly to use.

    The City of Philadelphia`s Division of Aviation (DOA) has begun construction of a new commuter runway, designated as Runway 8-26, at the Philadelphia International Airport. A portion of this runway will be constructed over a former Superfund site known as the Enterprise Avenue Landfill, which for many years was used to dispose of solid waste incinerator ash and other hazardous materials. The site was clay capped in the 1980`s, but in order for the DOA to use the site, additional remediation was needed to meet US EPA final closure requirements. One component of the closure plan included installation of a low permeability horizontal barrier above a very thin (approximately 0.61 to 0.91 meters) natural clay stratum which underlies an approximately 1020 m{sup 2} area of the landfill footprint so as to insure that a minimum 1.52 meter thick low permeability barrier exists beneath the entire 150,000 m{sup 2} landfill. The new barrier was constructed using jet grouting techniques to achieve remote excavation and replacement of the bottom 0.91 meters of the waste mass with a low permeability grout. The grout was formulated to meet the low permeability, low elastic modulus and compressive strength requirements of the project design. This paper will discuss the advantages of using jet grouting for the work and details the development of the grout mixture, modeling of the grout zone under load, field construction techniques, performance monitoring and verification testing.

    The US Air Force has sought to understand the provenance of radionuclides that were detected in monitor wells surrounding a closed solid-waste landfill at the former Lowry Air Force Base in Denver, Colorado. Groundwater concentrations of gross alpha, gross beta, and total uranium were thought to exceed regulatory standards. Down-gradient concentrations of these parameters exceeded up-gradient concentrations, suggesting that the landfill is leaching uranium to groundwater. Alternate hypotheses for the occurrence of the uranium included that either equipment containing refined uranium had been discarded or that uranium ore may have been disposed in the landfill, or that the uranium is naturally-occurring. Our study has concluded that the elevated radionuclide concentrations stem from naturally-occurring uranium in the regional watershed which has been preferentially deposited in paleo-channel sediments beneath the site. This study shows that a simple comparison of up-gradient versus down-gradient groundwater samples can be an inadequate method for determining whether heterogeneous geo-systems have been contaminated. It is important to understand the geologic depositional system, plus local geochemistry and how these factors impact contaminant transport. (authors)

  20. Complete decay of radionuclides: Implications for low-level waste disposal in municipal landfills

    Meck, R.A.

    1996-05-01

    The time required for the complete decay of a radioactive source can be quantified by specifying an acceptable probability and using an original derivation. The physical phenomenon of complete decay may be used as the technical basis to change regulations and permit, with public acceptance, the inexpensive disposal of short half-lived radioactive waste into municipal landfills. Current regulations require isolation of trash form the biosphere for 30 years during the post-closure control period for municipal landfills. Thirty years is sufficient time for complete decay of significant quantities of short-lived radionuclides, and there is a large decay capacity in the nation`s landfills. As the major generators of low-level radioactive waste with relatively short half-lives, the academic, medical, and research communities likely would benefit most from such regulatory relief. Disposal of such waste is prohibited or costly. The waste must be specially packaged, stored, transported, and disposed in designated repositories. Regulatory relief can be initiated by citizens since the Administrative Procedures Act gives citizens the right to petition for regulatory change. 10 refs., 2 tabs.

    The emissions of volatile, sulfur-containing compounds from the surfaces of 13 flue gas desulfurization (FGD) solids field storage sites have been characterized. The sulfur gas emissions from these storage surfaces were determined by measuring the sulfur gas enhancement of sulfur-free sweep air passing through a dynamic emission flux chamber placed over selected sampling areas. Samples of the enclosure sweep air were cryogenically concentrated in surface-deactivated Pyrex U traps. Analyses were conducted by wall-coated, open-tubular, capillary column, cryogenic, temperature-programmed gas chromatography using a sulfur-selective flame photometric detector. Several major variables associated with FGD sludge production processes were examined in relation to the measured range and variations in sulfur fluxes including: the sulfur dioxide scrubbing reagent used, sludge sulfite oxidation, unfixed or stabilized (fixed) FGD solids, and ponding or landfill storage. The composition and concentration of the measured sulfur gas emissions were found to vary with the type of solids, the effectiveness of rainwater drainage from the landfill surface, the method of impoundment, and the sulfate/sulfite ratio of the solids. The FGD solids emissions may contain hydrogen sulfide, carbonyl sulfide, dimethyl sulfide, carbon disulfide, and dimethyl disulfide in varying concentrations and ratios. In addition, up to four unidentified organo-sulfur compounds were found in the emissions from four different FGD solids. The measured, total sulfur emissions ranged from less than 0.01 to nearly 0.3 kg of sulfur per day for an equivalent 40.5 hectare (100 acre) FGD solids impoundment surface.

    A unique opportunity for cooperation and community development exists in Harrisonburg, Virginia. James Madison University, located in Harrisonburg, is undergoing an aggressive growth plan of its academic base which also includes the physical expansion of its campus. The City of Harrisonburg is presently supplying steam to meet a portion of the heating needs of the existing James Madison campus from a city owned and operated waste-to-energy plant. In an effort of cooperation, Harrisonburg and James Madison University have now negotiated an agreement for the city to provide all of the heating and cooling requirements of the new campus expansion. In another unique turn of events, the local electrical power distributor, Harrisonburg Electric Commission, approached the city concerning the inclusion of cogeneration in the project in order to reduce and maintain existing electric rates thus further benefiting the community. Through the cooperation of these three entities, the conceptual design phase of the project has been completed. The plant design developed through this process includes 3,000 tons of chilled water capacity, an additional 64,000 lb/hr of steam capacity and 2.5 MW of cogeneration capacity. This paper describes the conceptual design process for this interesting project.

    During 1986, the environmental monitoring program was continued at the former Middlesex Sampling Plant (MSP) and former Middlesex Municipal Landfill (MML) sites, located in the Borough of Middlesex, New Jersey. The MSP and MML sites are part of the Formerly Utilized Sites Remedial Action Program (FUSRAP), a DOE program to decontaminate or otherwise control sites where residential radioactive materials remain from either the early years of the nation's atomic energy program or commercial operations causing conditions that Congress has mandated DOE to remedy. The monitoring program at the MSP and MML measures radon gas concentrations in air; external gamma radiation levels; and uranium and radium concentrations in surface water, groundwater, and sediment. To verify that sites are in compliance with the DOE radiation protection standard (100 mrem/yr) and to assess their potential effect on public health, the radiation dose was calculated for the maximally exposed individual. Based on the conservative scenarios described in the report, this individual, at the MSP, would receive an annual external exposure approximately equivalent to 10 percent of the DOE radiation protection standard. By comparison, the incremental dose received from living in a brick house versus a wooden house is about the same. At the MML, the annual external exposure to the maximally exposed individual would be less than 1% of the standard. The cumulative dose to the population within an 80-km (50-mi) radius of the sites that would result from radioactive materials present at the MSP and MML would be indistinguishable from the dose that the same population would receive from naturally occurring radioactive sources. Results of the 1986 monitoring show that the MSP and MML are in compliance with the DOE radiation protection standard. 14 refs., 13 figs., 23 tabs.

    A probabilistic performance assessment has been conducted to evaluate the fate and transport of radionuclides (americium-241, cesium-137, cobalt-60, plutonium-238, plutonium-239, radium-226, radon-222, strontium-90, thorium-232, tritium, uranium-238), heavy metals (lead and cadmium), and volatile organic compounds (VOCs) at the Mixed Waste Landfill (MWL). Probabilistic analyses were performed to quantify uncertainties inherent in the system and models for a 1,000-year period, and sensitivity analyses were performed to identify parameters and processes that were most important to the simulated performance metrics. Comparisons between simulated results and measured values at the MWL were made to gain confidence in the models and perform calibrations when data were available. In addition, long-term monitoring requirements and triggers were recommended based on the results of the quantified uncertainty and sensitivity analyses. At least one-hundred realizations were simulated for each scenario defined in the performance assessment. Conservative values and assumptions were used to define values and distributions of uncertain input parameters when site data were not available. Results showed that exposure to tritium via the air pathway exceeded the regulatory metric of 10 mrem/year in about 2% of the simulated realizations when the receptor was located at the MWL (continuously exposed to the air directly above the MWL). Simulations showed that peak radon gas fluxes exceeded the design standard of 20 pCi/m{sup 2}/s in about 3% of the realizations if up to 1% of the containers of sealed radium-226 sources were assumed to completely degrade in the future. If up to 100% of the containers of radium-226 sources were assumed to completely degrade, 30% of the realizations yielded radon surface fluxes that exceeded the design standard. For the groundwater pathway, simulations showed that none of the radionuclides or heavy metals (lead and cadmium) reached the groundwater during

Department of Energy (DOE), National Energy Technology Laboratory (NETL) to assess the technoeconomic viability of building an Early Entrance Co-Production Plant (EECP) in the United States to produce ultra clean Fischer-Tropsch (FT) transportation fuels with either power or steam as the major co-product. The EECP design includes recovery and gasification of low-cost coal waste (culm) from physical coal cleaning operations and will assess blends of the culm with coal or petroleum coke. The project has three phases. Phase I is the concept definition and engineering feasibility study to identify areas of technical, environmental and financial risk. Phase II is an experimental testing program designed to validate the coal waste mixture gasification performance. Phase III updates the original EECP design based on results from Phase II, to prepare a preliminary engineering design package and financial plan for obtaining private funding to build a 5,000 barrel per day (BPD) coal gasification/liquefaction plant next to an existing co-generation plant in Gilberton, Schuylkill County, Pennsylvania.

    Highlights: > A quasi-three-dimensional slope stability analysis method was proposed. > The proposed method is a good engineering tool for 3D slope stability analysis. > Factor of safety from 3D analysis is higher than from 2D analysis. > 3D analysis results are more sensitive to cohesion than 2D analysis. - Abstract: Limited space for accommodating the ever increasing mounds of municipal solid waste (MSW) demands the capacity of MSW landfill be maximized by building landfills to greater heights with steeper slopes. This situation has raised concerns regarding the stability of high MSW landfills. A hybrid method for quasi-three-dimensional slope stability analysis based on the finite element stress analysis was applied in a case study at a MSW landfill in north-east Spain. Potential slides can be assumed to be located within the waste mass due to the lack of weak foundation soils and geosynthetic membranes at the landfill base. The only triggering factor of deep-seated slope failure is the higher leachate level and the relatively high and steep slope in the front. The valley-shaped geometry and layered construction procedure at the site make three-dimensional slope stability analyses necessary for this landfill. In the finite element stress analysis, variations of leachate level during construction and continuous settlement of the landfill were taken into account. The 'equivalent' three-dimensional factor of safety (FoS) was computed from the individual result of the two-dimensional analysis for a series of evenly spaced cross sections within the potential sliding body. Results indicate that the hybrid method for quasi-three-dimensional slope stability analysis adopted in this paper is capable of locating roughly the spatial position of the potential sliding mass. This easy to manipulate method can serve as an engineering tool in the preliminary estimate of the FoS as well as the approximate position and extent of the potential sliding mass. The result that Fo

    The Environmental Protection Agency and the National Renewable Energy Laboratory developed this best practices document to address common technical challenges for siting solar photovoltaics (PV) on municipal solid waste (MSW) landfills. The purpose of this document is to promote the use of MSW landfills for solar energy systems. Closed landfills and portions of active landfills with closed cells represent thousands of acres of property that may be suitable for siting solar photovoltaics (PV). These closed landfills may be suitable for near-term construction, making these sites strong candidate to take advantage of the 30% Federal Business Energy Investment Tax Credit. It was prepared in response to the increasing interest in siting renewable energy on landfills from solar developers; landfill owners; and federal, state, and local governments. It contains examples of solar PV projects on landfills and technical considerations and best practices that were gathered from examining the implementation of several of these projects.

    A process is being developed that produces a fuel gas with a heating value of 500 Btu/SCF from diverse forms of biomass, including shredded bark, wood chips, and sawdust. The system uses a high throughput, non-oxygen gasifier that employs sand circulation to supply process heat. Results obtained with a 10-inch I.D. gasifier are presented and compared with those in a 6-inch I.D. reactor. Feed rates up to 12 tons/day (dry) have been achieved corresponding to a specific wood throughput of 2000 lbs/ft/sup 2/-hr. Gas compositions in the two reactors are in excellent agreement and performance in the larger reactor, as measured by carbon conversion, is significantly improved. Cost projections comparing this process with direct combustion are presented that indicate gasification technology should have very significant cost advantages for both generation of plant steam and cogeneration of electricity. 5 refs., 14 figs., 5 tabs.

    A system model was used to develop an autothermal reforming fuel processor to meet the targets of 80% efficiency (higher heating value) and start-up energy consumption of less than 500 kJ when operated as part of a 1-kWe natural-gas fueled fuel cell system for cogeneration of heat and power. The key catalytic reactors of the fuel processor--namely the autothermal reformer, a two-stage water gas shift reactor and a preferential oxidation reactor--were configured and tested in a breadboard apparatus. Experimental results demonstrated a reformate containing {approx} 48% hydrogen (on a dry basis and with pure methane as fuel) and less than 5 ppm CO. The effects of steam-to-carbon and part load operations were explored.

    The main objective of this study was to assess the feasibility of treating sanitary landfill leachate using a combined anaerobic and activated sludge system. A high-strength leachate from Shiraz municipal landfill site was treated using this system. A two-stage laboratory-scale anaerobic digester under mesophilic conditions and an activated sludge unit were used. Landfill leachate composition and characteristics varied considerably during 8 months experiment (COD concentrations of 48,552-62,150 mg/L). It was found that the system could reduce the COD of the leachate by 94% at a loading rate of 2.25 g COD/L/d and 93% at loading rate of 3.37 g COD/L/d. The anaerobic digester treatment was quite effective in removing Fe, Cu, Mn, and Ni. However, in the case of Zn, removal efficiency was about 50%. For the rest of the HMs the removal efficiencies were in the range 88.8-99.9%. Ammonia reduction did not occur in anaerobic digesters. Anaerobic reactors increased alkalinity about 3.2-4.8% in the 1st digester and 1.8-7.9% in the 2nd digester. In activated sludge unit, alkalinity and ammonia removal efficiency were 49-60% and 48.6-64.7%, respectively. Methane production rate was in the range of 0.02-0.04, 0.04-0.07, and 0.02-0.04 L/g COD{sub rem} for the 1st digester, the 2nd digester, and combination of both digesters, respectively; the methane content of the biogas varied between 60% and 63%.

    The Sayreville Landfill site, located in Middlesex County, New Jersey, was used primarily for the disposal of municipal wastes from 1970 through 1977. Illegal dumping of possibly hazardous materials allegedly occurred during active landfill operations and after landfill closure. Organic and inorganic compounds were found in on-site subsurface soil, ground water, surface water, and sediments at levels above public health assessment comparison values. The community is concerned about the safety of eating fish from the South River. The potential exists for past, present, and future exposure of local residents and workers to contaminated subsurface soil, nearby surface water, and sediments. The New Jersey Department of Health (NJDOH) has concluded that the site is an indeterminate public health hazard since insufficient data exist for all environmental media to which humans may be exposed.

    The US Department of Energy (DOE) is proposing to install a wet ash handling system to dewater bottom ash from the coal-fired steam plant at its Y-12 Plant and to construct a new landfill for disposal of industrial wastes, including the dewatered bottom ash. The DOE operates three major facilities on its Oak Ridge Reservation (ORR). Operation of these facilities results in the production of a variety of nonhazardous, nonradioactive solid wastes (approximately 300 m{sup 3} per day, compacted) including sanitary wastes, common industrial wastes and construction debris. At the current rate of use, this existing landfill will be filled within approximately 18 months, and more space is urgently needed. In an effort to alleviate this problem, DOE and WMD management propose to create additional landfill facilities at a nearby site. The potential environmental impacts associated with this proposed action are the subject of this environmental assessment (EA).

    Federal and state regulations governing the operation of landfills require utilization of ground-water monitoring systems to determine whether or not landfill operations impact ground water at the point of compliance (ground water beneath the perimeter of the facility). A detection-level ground-water monitoring system was designed, installed, and initiated at the Hanford Site Solid Waste Landfill (SWL). Chlorinated hydrocarbons were detected at the beginning of the ground-water monitoring program and continue to be detected more than 1 year later. The most probable source of the chlorinated hydrocarbons is washwater discharged to the SWL between 1985 and 1987. This is an interim report and includes data from the characterization work that was performed during well installation in 1987, such as field observations, sediment studies, and geophysical logging results, and data from analyses of ground-water samples collected in 1987 and 1988, such as field parameter measurements and chemical analyses. 38 refs., 27 figs., 8 tabs.

    The general objective of the study was to assist the Miamisburg Closure Project in their efforts to develop and refine a comprehensive, technically sound strategy for remediation of groundwater contaminated with trichloroethylene and other volatile organic compounds in the vicinity of the landfill in Operable Unit 1. To provide the necessary flexibility to the site, regulators and stakeholders, the resulting evaluation considered a variety of approaches ranging from ''no further action'' to waste removal. The approaches also included continued soil vapor extraction, continued groundwater pump and treat, monitored natural attenuation, biostimulation, partitioning barriers, hydrologic modification, and others.

    A large-scale field demonstration comparing final landfill cover designs has been constructed and is currently being monitored at Sandia National Laboratories in Albuquerque, New Mexico. Two conventional designs (a RCRA Subtitle `D' Soil Cover and a RCRA Subtitle `C' Compacted Clay Cover) were constructed side-by-side with four alternative cover test plots designed for dry environments. The demonstration is intended to evaluate the various cover designs based on their respective water balance performance, ease and reliability of construction, and cost. This paper presents an overview of the ongoing demonstration.
