    Flue gas desulphurization (FGD) materials are produced in abundant quantities by coal burning utilities. Due to environmental restrains, flue gases must be ''cleaned'' prior to release to the atmosphere. They are two general methods to ''scrub'' flue gas: wet and dry. The choice of scrubbing material is often defined by the type of coal being burned, i.e. its composition. Scrubbing is traditionally carried out using a slurry of calcium containing material (slaked lime or calcium carbonate) that is made to contact exiting flue gas as either a spay injected into the gas or in a bubble tower. The calcium combined with the SO{sub 2} in the gas to form insoluble precipitates. Some plants have been using dry injection of these same materials or their own Class C fly ash to scrub. In either case the end product contains primarily hannebachite (CaSO{sub 3} {center_dot} 1/2H{sub 2}O) with smaller amounts of gypsum (CaSO{sub 4} {center_dot} 2H{sub 2}O). These materials have little commercial use. Experiments were carried out that were meant to explore the feasibility of using blends of hannebachite and fly ash mixed with concentrated sodium hydroxide to make masonry products. The results suggest that some of these mixtures could be used in place of conventional Portland cement based products such as retaining wall bricks and pavers.

    There is considerable interest in using cementitious coal combustion by-products in waste disposal applications. Among coal combustion residuals, cementitious materials include high-calcium fly ash, dry process flue gas desulfurization by-products, and {open_quotes}clean coal{close_quotes} by-products (various fluidized bed combustion and sorbent injection by-products that utilize lime or limestone for scrubbing SO{sub 2}). Hydration of almost all of these by-products results in ettringite formation. When formed, ettringite structure phases are effective at immobilizing trace elements in oxyanion speciation, particularly selenite, selenate and borate. However, the long-term stability of the matrix is in question. We have studied the stability of the ettringite-based cement matrices in laboratory tests, and through examining cores obtained from disposed materials ranging in age from one to twelve years. Results relating to the effects of carbonation on ettringite in these hydrated by-products, and to the formation of thaumasite in disposed materials will be presented.

    The US Bureau of Mines has developed technology to recover by-product materials from aluminum scrap using engineered scavenger compounds (ESC). ESCs are structural oxides with a channel or tunnel structure that allows them to hold ions of a specific sizes and charges. The scavenging reaction is easily reversible allowing the ESC to be recharged for continued use and the ion is recovered as an electrodeposit. Key features of this novel technology are: (a) ESC systems are designed to have a high degree of selectivity for a desired ionic species. (b) The recovered material requires little or no additional reprocessing prior to reuse. Two current uses for the ESC technology that are described in this paper are the removal and recycle of lithium (Li) from lithium aluminum (Li-Al) alloys; and, using ESCs as a replacement for the conventional demaging (magnesium removal) technology used by the secondary casting industry. Research indicates that the ESC technology proposed for both these applications has either distinct economic and/or environmental advantages over previously employed methods of recovering metal values from aluminum scrap.

    In the study, effects of opaque building materials on the heating of buildings by the passive solar energy system have been investigated. The quantity of solar energy absorbed by surfaces and its transfer indoors have been the main subjects of the research. Relevant surface properties and structures of opaque building skin materials have been determined experimentally and theoretically according to the meteorological, geographical and atmospheric characteristics of the regions. A laminar composite building element made of light and heavy materials has been suggested to obtain an efficient solution.

    The 1990 amendments to the Clean Air Act have spurred the development of flue gas desulfurization (FGD) processes, several of which produce a dry, solid by-product material consisting of excess sorbent, reaction products containing sulfates and sulfites, and coal fly ash. Presently FGD by-product materials are treated as solid wastes and must be landfilled. However, landfill sites are becoming more scarce and tipping fees are constantly increasing. It is, therefore, highly desirable to find beneficial reuses for these materials provided the environmental impacts are minimal and socially acceptable. Phase 1 results of a 4 and 1/2 year study to demonstrate large volume beneficial uses of FGD by-products are reported. The purpose of the Phase 1 portion of the project was to characterize the chemical, physical, mineralogical and engineering properties of the FGD by-product materials obtained from various FGD technologies being developed in the state of Ohio. Phase 1 also involved the collection of baseline economic data related to the beneficial reuse of these FGD materials. A total of 58 samples were collected and analyzed. In summary Phase 1 results revealed that FGD by-product materials are essentially coal fly ash materials diluted with unreacted sorbent and reaction products. High volume beneficial reuses will depend on the economics of their substituting for existing materials for various types of applications (e.g. as an agricultural liming material, soil borrow for highway embankment construction, and reclamation of active and abandoned surface coal mines). Environmental constraints to the beneficial reuse of dry FGD byproduct materials, based on laboratory and leachate studies, seem to be less than for coal fly ash.

    With the recent passing of new legislation designed to permanently cap and reduce mercury emissions from coal-fired utilities, it is more important than ever to develop and improve upon methods of controlling mercury emissions. One promising technique is carbon sorbent injection into the flue gas of the coal-fired power plant. Currently, this technology is very expensive as costly commercially activated carbons are used as sorbents. There is also a significant lack of understanding of the interaction between mercury vapor and the carbon sorbent, which adds to the difficulty of predicting the amount of sorbent needed for specific plant configurations. Due to its inherent porosity and adsorption properties as well as on-site availability, carbons derived from gasifiers are potential mercury sorbent candidates. Furthermore, because of the increasing restricted use of landfilling, the coal industry is very interested in finding uses for these materials as an alternative to the current disposal practice. The results of laboratory investigations and supporting technical assessments conducted under DOE Subcontract No. DE-FG26-03NT41795 are reported for the period September 1, 2004 to August 31, 2005. This contract is with the University of Kentucky Research Foundation, which supports work with the University of Kentucky Center for Applied Energy Research and The Pennsylvania State University Energy Institute. The worked described was part of a project entitled ''Advanced Gasification By-Product Utilization''. This work involves the development of technologies for the separation and characterization of coal gasification slags from operating gasification units, activation of these materials to increase mercury and nitrogen oxide capture efficiency, assessment of these materials as sorbents for mercury and nitrogen oxides, and characterization of these materials for use as polymer fillers.

    Municipal water rates are expected to satisfy three objectives: efficiency, revenue neutrality to the utility, and distributional equity. Unfortunately, adjusting rates to efficiently achieve use and conservation targets would ordinarily generate excessive revenues. Rather than mold one tool to the service of three masters, this article suggests combining three separate tools. The first sets the water rate to cover the utility`s costs. The second assigns customers allotments to water use. The third either charges a fee for use that exceeds the customer`s allotment or hands out rebates for consumption below that allotment. The fees pay for the rebates--thus the term feebate. The outcome is (1) revenues to the utility just sufficient to cover costs, (2) efficient water consumption by municipal water customers without conservation mandates, and (3) revenue effects that can be spread fairly across various categories of customers.

    The need to remove the bulk of ash contained in flue gas from coal-fired power plants coupled with increasingly strict environmental regulations in the USA result in increased generation of solid materials referred to as coal utilisation by-products, or CUBs. More than 40% of CUBs were sold or reused in the USA in 2004 compared to less than 25% in 1996. A goal of 50% utilization has been established for 2010. The American Coal Ash Association (ACCA) together with the US Department of Energy's Power Plant Improvement Initiative (PPPI) and Clean Coal Power Initiative (CCPI) sponsor a number of projects that promote CUB utilization. Several are mentioned in this report. Report sections are: Executive summary; Introduction; Where do CUBs come from?; Market analysis; DOE-sponsored CUB demonstrations; Examples of best-practice utilization of CUB materials; Factors limiting the use of CUBs; and Conclusions. 14 refs., 1 fig., 5 tabs., 14 photos.

    Conservative Remapper (CORE) is a C++ language software library for remapping cell masses and cell-averaged densities on unstructured two dimensional grids, maintaining conservation of total mass in the process. CORE contains implementation of two remapping algorithms: a new, efficient "swept region" algorithm, and a more traditional algorithm basedon the computation of cell intersections. Grids may be Cartesian or cylindrical, and cells may have three or more vertices, with no upper limit. CORE can run inmore » serial and in parallel, but in order to achieve wide applicability, CORE used no particular parallel communication library. Instead it achieves parallel communication through strategically placed, user defined callbacks. Users can also provide callbacks to redefine different parts or subcomponents of the remapping process. CORE allows the use of different data types, e.g. single-, double-, and quadruple- precision floating-point numbers, through the use of C++ templates. Using CORE is simple, and requires no configuration scripts or makefiles.« less

    Low NO{sub x} combustion practices are critical for reducing NO{sub x} emissions from power plants. These low NO{sub x} combustion practices, however, generate high residual carbon contents in the fly ash produced. These high carbon contents threaten utilization of this combustion by-product. This research has successfully developed a separation technology to render fly ash into useful, quality-controlled materials. This technology offers great flexibility and has been shown to be applicable to all of the fly ashes tested (more than 10). The separated materials can be utilized in traditional fly ash applications, such as cement and concrete, as well as in nontraditional applications such as plastic fillers, metal matrix composites, refractories, and carbon adsorbents. Technologies to use beneficiated fly ash in these applications are being successfully developed. In the future, we will continue to refine the separation and utilization technologies to expand the utilization of fly ash. The disposal of more than 31 million tons of fly ash per year is an important environmental issue. With continued development, it will be possible to increase economic, energy and environmental benefits by re-directing more of this fly ash into useful materials.

    New flue gas desulfurization (FGD) scrubbing technologies create a dry, solid by-product material consisting of excess sorbent, reaction product that contains sulfate and sulfite, and coal fly ash. Generally, dry FGD by-products are treated as solid wastes and disposed in landfills. However, landfill sites are becoming scarce and tipping fees are constantly increasing. Provided the environmental impacts are socially and scientifically acceptable, beneficial uses via recycling can provide economic benefits to both the producer and the end user of the FGD. A study titled ''Land Application Uses for Dry Flue Gas Desulfurization By-Products'' was initiated in December, 1990 to develop and demonstrate large volume, beneficial uses of FGD by-products. Phase 1 and Phase 2 reports have been published by the Electric Power Research Institute (EPRI), Palo Alto, CA. Phase 3 objectives were to demonstrate, using field studies, the beneficial uses of FGD by-products (1) as an amendment material on agricultural lands and on abandoned surface coal mine land, (2) as an engineering material for soil stabilization and raid repair, and (3) to assess the environmental and economic impacts of such beneficial uses. Application of dry FGD by-product to three soils in place of agricultural limestone increased alfalfa (Medicago sativa L.) and corn (Zea may L.) yields. No detrimental effects on soil and plant quality were observed.

    Flue gas desulfurization (FGD) scrubbing technologies create several types of by-products. This project focused primarily on by-product materials obtained from what are commonly called ''dry scrubbers'' which produce a dry, solid material consisting of excess sorbent, reaction product that contains sulfate and sulfite, and coal fly ash. Prior to this project, dry FGD by-products were generally treated as solid wastes and disposed in landfills. However, landfill sites are becoming scarce and tipping fees are constantly increasing; The major objective of this project was to develop beneficial uses, via recycling, capable of providing economic benefits to both the producer and the end user of the FGD by-product. It is equally important, however, that the environmental impacts be carefully assessed so that the new uses developed are not only technically feasible but socially acceptable. Specific objectives developed for this project were derived over an 18-month period during extensive discussions with personnel from industry, regulatory agencies and research institutions. These were stated as follows: Objective 1: To characterize the material generated by dry FGD processes. Objective 2: To demonstrate the utilization of dry FGD by-product as a soil amendment on agricultural lands and on abandoned and active surface coal mines in Ohio. Objective 3: To demonstrate the use of dry FGD by-product as an engineering material for soil stabilization. Objective 4: To determine the quantities of dry FGD by-product that can be utilized in each of these applications. Objective 5. To determine the environmental and economic impacts of utilizing the material. Objective 6. To calibrate environmental, engineering, and economic models that can be used to determine the applicability and costs of utilizing these processes at other sites.

    A study was initiated in December 1990 to demonstrate large volume beneficial uses of flue gas desulfurization (FGD) by-products. A Phase 1 report provided results of an extensive characterization of chemical, physical, mineralogical and engineering properties of 58 dry FGD by-product samples. The Phase 1 report concluded that high volume beneficial reuses will depend on the economics related to their ability to substitute for existing materials for various types of applications (e.g. as an agricultural liming material, soil borrow for highway embankment construction, and reclamation of active and abandoned surface coal mine lands). Phase 2 objectives were (1) to conduct laboratory and greenhouse studies of FGD and soil (spoil) mixtures for agronomic and engineering applications, (2) to initiate field studies related to high volume agronomic and engineering uses, and (3) to develop the basic methodological framework for estimation of the financial and economic costs and benefits to society of several FGD reuse options and to make some preliminary runs of economic models. High volume beneficial reuses of dry FGD by-products have been successfully demonstrated. Adverse environmental impacts have been negligible. Although few sources of dry FGD by-products currently exist in Ohio and the United States there is potential for smaller coal-fired facilities to adopt S0{sub 2} scrubbing technologies that produce dry FGD material. Also much of what we have learned from studies on dry FGD by-products is applicable to the more prevalent wet FGD by-products. The adaptation of the technologies demonstrated in this project seem to be not only limited by economic constraints, but even more so, by the need to create awareness of the market potential of using these FGD by-products.

    The world production of by-products from power plants is in excess of 500 Mt/year. Most of it consists of coal fly ash and bottom ash, but an increasing share is made up of by-products from flue gas desulfurization processes. In some countries less than 10% of the by-products are utilized, whereas the utilization ratio is as high as 90% in others. In the EU about half of the by-products is utilized, but according to the EU's policy the degree of utilization should be increased. Coal fly ash can be used in concrete pursuant to the provisions of the European standard EN 450, Fly Ash for Concrete. In addition quality fly ash can be used in the production of cement and gas concrete and in the building industry. Road construction and soil amendment can also make use of this material. Gypsum produced as a result of the flue gas desulfurization process can be used as wall boards, in the building industry and in the production of cement. Also other by-products from the flue gas desulfurization processes can be used for industrial purposes. By-products where utilization is no option will be disposed of. According to the EU's environmental legislation most of the by-products from the power plants are categorized as non-hazardous waste. This papers discusses how to design a landfill deposit for power plant residues in accordance with applicable EU-directives. However, as can be seen from the conclusion it will become increasingly difficult in the future to deposit these residues. This will urge power producers to cooperate with relevant industries to ensure utilization of a larger part of the by-products and to create solutions that will be profitable to both parties.

    Top address a growing national problem with generation of wastes and by-products, TVA has been involved for several years with developing and commercializing environmentally responsible practices for eliminating, minimizing, or utilizing various wastes/by-products. In many cases, reducing waste generation is impractical, but the wastes/by-products can be converted into other environmentally sound products. In some instances, conversion of safe, value-added agricultural products in the best or only practical alternative. TVA is currently involved with a diversity of projects converting wastes/by-products into safe, economical, and agriculturally beneficial products. Environmental improvement projects have involved poultry litter, cellulosic wastes, used battery acid, ammonium sulfate fines, lead smelting effluents, deep-welled sulfuric acid/ammonium bisulfate solutions, wood ash, waste magnesium ammonium sulfate slurry from recording tape production, and ammunition plant waste sodium nitrate/ammonium nitrate streams.

    1988-09-01

    This report presents the results of an investigation into the utilization potential of by-products from the following advanced SO/sub 2/ control processes: Atmospheric Fluidized Bed Combustion; Calcium Spray Drying; Limestone Furnace Injection; Sodium Sorbent Injection; and Calcium Sorbent Injection. Utilization applications identified as potentially feasible (from both technical and market perspectives) in the preliminary investigation (EPRI CS-5269) were evaluated through small-scale laboratory testing. The applications considered were primarily low to medium technology process and medium to high volume use applications. The laboratory test results were evaluated in concert with by-product physical, chemical and extract characteristics (developed during EPRI Research Project 2708-1) and a market assessment. Then, an economic evaluation was performed for each utilization application based upon a typical or hypothetical by-product marketing situation in which an advanced SO/sub 2/ control by-product could be substituted for a competing material on a local project or in a local product. Finally, based on the major factors considered in this project (laboratory characterization, technical feasibility evaluation, and economic and market assessments), the utilization potential for each application considered was rated as high, medium or low, and future research needs were identified. The following utilization applications were found to have a high potential for the majority of the calcium-based advanced SO/sub 2/ control by-products: road base, soil and sludge stabilization and grout applications. 76 refs., 18 figs., 70 tabs.

    The 1990 amendments to the Clean Air Act have spurred the development of flue gas desulfurization (FGD) processes, several of which produce a dry, solid by-product material consisting of excess sorbent, reaction products containing sulfates and sulfites, and coal fly ash. Presently FGD by-product materials are treated as solid wastes and must be landfilled. However, landfill sites are becoming more scarce and tipping fees are constantly increasing. It is, therefore, highly desirable to find beneficial reuses for these materials provided the environmental impacts are minimal and socially acceptable. Phase 1 results of a 4 and 1/2 year study to demonstrate large volume beneficial uses of FGD by-products are reported. The purpose of the Phase 1 portion of the project was to characterize the chemical, physical, mineralogical and engineering properties of the FGD by-product materials obtained from various FGD technologies being developed in the state of Ohio. Phase 1 also involved the collection of baseline economic data related to the beneficial reuse of these FGD materials. A total of 58 samples were collected and analyzed. In summary Phase 1 results revealed that FGD by-product materials are essentially coal fly ash materials diluted with unreacted sorbent and reaction products. High volume beneficial reuses will depend on the economics of their substituting for existing materials for various types of applications (e.g. as an agricultural liming material, soil borrow for highway embankment construction, and reclamation of active and abandoned surface coal mines). Environmental constraints to the beneficial reuse of dry FGD byproduct materials, based on laboratory and leachate studies, seem to be less than for coal fly ash.

  17. Electricity from coal and utilization of coal combustion by-products

    Most electricity in the world is conventionally generated using coal, oil, natural gas, nuclear energy, or hydropower. Due to environmental concerns, there is a growing interest in alternative energy sources for heat and electricity production. The major by-products obtained from coal combustion are fly ash, bottom ash, boiler slag, and flue gas desulfurization (FGD) materials. The solid wastes produced in coal-fired power plants create problems for both power-generating industries and environmentalists. The coal fly ash and bottom ash samples may be used as cementitious materials.

  19. Economical Recovery of By-products in the Mining Industry

    SciTech Connect

    Berry, J.B.

    2001-12-05

    The U.S. Department of Energy (DOE) Office of Industrial Technologies, Mining Industry of the Future Program, works with the mining industry to further the industry's advances toward environmental and economic goals. Two of these goals are (1) responsible emission and by-product management and (2) low-cost and efficient production (DOE 1998). DOE formed an alliance with the National Mining Association (NMA) to strengthen the basis for research projects conducted to benefit the mining industry. NMA and industry representatives actively participate in this alliance by evaluating project proposals and by recommending research project selection to DOE. Similarly, the National Research Council (NRC) has recently and independently recommended research and technology development opportunities in the mining industry (NRC 2001). The Oak Ridge National Laboratory (ORNL) and Colorado School of Mines engineers conducted one such project for DOE regarding by -product recovery from mining process residue. The results of this project include this report on mining industry process residue and waste with opportunity for by-product recovery. The U.S. mineral processing industry produces over 30,000,000 metric tons per year of process residue and waste that may contain hazardous species as well as valuable by-products. This study evaluates the copper, lead, and zinc commodity sectors which generate between 23,300,000 and 24,000,000 metric tons per year. The distribution of residual elements in process residues and wastes varies over wide ranges* because of variations in the original ore content as it is extracted from the earth's crust. In the earth's crust, the elements of interest to mining fall into two general geochemical classifications, lithophiles and chalcophiles** (Cox 1997). Groups of elements are almost always present together in a given geochemical classification, but the relative amounts of each element are unique to a particular ore body. This paper generally describes

    2000-02-29

    Few, if any, economical alternatives exist for small coal-fired boilers that require a flue-gas desulfurization (FGD) system which does not generate wastes. A new duct-injection technology, called "Fluesorbent," was developed to help fill this gap. Fluesorbent was intentionally designed so that the saturated S02-sorbent materials can be used as beneficial soil amendments after they were used for FGD. A. Project Objective: The objective of this project was to demonstrate in the field that saturated Fluesorbent materials can be utilized beneficially on agricultural and grass lands. B. Project Results: The results of this project suggest that, indeed, saturated Fluesorbent has excellent potential as a commercial soil amendment for crops, such as alfalfa and soybeans, and for turf. Yields of alfalfa and turf were substantially increased in field testing on acidic soils by one-time applications of Fluesorbent FGD by-products. In the first two years of field testing, alfalfa yields on field plots with the FGD by-products were approximately 40% greater than on plots treated with an equivalent amount of agricultural lime. In a third, drought-influenced year, the gains were smaller. Turf grass growth was fully twice that of untreated plots and more than 10% greater than with ag-lime. A small farm trial with a modified version of the Fluesorbent by-product increased soybean yield by 25%. A small trial with corn, however, indicated no significant improvement. Even though the Fluesorbent contained fly ash, the alfalfa and turf grown in FGD-treated plots contained significantly lower levels of heavy metals than that grown in untreated or lime-treated plots. In a project greenhouse experiment, the fly ashes from five different coal boilers from around Ohio produced equivalent yields when mixed with Fluesorbent, indicating wide potential applicability of the new technology. The Fluesorbent materials were also found to be easy to extrude into pellets for use with mixed fertilizers

  5. Management of dry flue gas desulfurization by-products in underground mines

    SciTech Connect

    Sevim, H.

    1997-06-01

    Disposal of coal combustion by-products (CCBs) in an environmentally sound manner is a major issue facing the coal and utility industries in the US today. Disposal into abandoned sections of underground coal mines may overcome many of the surface disposal problems along with added benefits such as mitigation of subsidence and acid mine drainage. However, many of the abandoned underground coal mines are located far from power plants, requiring long distance hauling of by-products which will significantly contribute to the cost of disposal. For underground disposal to be economically competitive, the transportation and handling cost must be minimized. This requires careful selection of the system and optimal design for efficient operation. The materials handling and system economics research addresses these issues. Transportation and handling technologies for CCBs were investigated from technical, environmental and economic points of view. Five technologies were found promising: (1) Pneumatic Trucks, (2) Pressure Differential Rail Cars, (3) Collapsible Intermodal Containers, (4) Cylindrical Intermodal Tanks, and (5) Coal Hopper Cars with Automatic Retractable Tarping. The first two technologies are currently being utilized in transporting by-products from power plants to disposal sites, whereas the next three are either in development or in conceptualization phases. In this research project, engineering design and cost models were developed for the first four technologies. The engineering design models are in the form of spreadsheets and serve the purpose of determining efficient operating schedules and sizing of system components.

  6. CHARACTERIZATION OF COAL COMBUSTION BY-PRODUCTS FOR THE RE-EVOLUTION OF MERCURY INTO ECOSYSTEMS

    SciTech Connect

    J.A. Withum; R.M. Statnick

    2001-09-01

    EPA and state environmental agencies are suggesting that mercury (Hg) in coal combustion by-products is re-emitted into local ecosystems by additional processing to final products (i.e., wallboard, etc.), by dissolution into groundwater, or by reactions with anaerobic bacteria. This perception may limit the opportunities to use coal combustion by-products in recycle/reuse applications. In this program, CONSOL Energy is conducting a comprehensive sampling and analytical program to address this concern. If the results of this work demonstrate that re-emissions of Hg from waste disposal and by-product utilization are over-stated, additional regulations regarding coal combustion, waste disposal, and waste material utilization will not be required. This will result in continued low energy cost that is beneficial to the national economy and stability of local economies that are dependent on coal. In this quarter, laboratory equipment was assembled and blank test runs were made, manufactured aggregate and spray dryer ash samples were collected and leached, and fly ash and FGD slurry samples from an Ohio bituminous coal-fired utility were collected for leaching.

    Zhang, M.; Feng, A.; Deschamps, R.

    1996-11-01

    The generation of coal combustion by-products (CCBPs) by utility companies and private industries is increasing and the trend is expected to continue in the foreseeable future. A large roadway embankment is currently under construction using several CCBPs as structural fill. The project site is located on the Purdue University campus in West Lafayette, Indiana. A paved road will be constructed on the crest of this embankment to extend Russell Street, providing convenient access to the southern expansion of Purdue University`s campus. The embankment is approximately 700 feet in length, with a maximum crest height of about 40 feet. The crest will be about 50 feet wide and a maximum base width of 250 feet. A comprehensive geotechnical laboratory testing and field monitoring program is being implemented to evaluate the physical and mechanical characteristics of various CCBPs and to predict the performance of the embankment during and after construction. Preliminary geotechnical laboratory testing results are presented in this paper.

    1995-12-31

    In the present work, a flue gas desulfurization (FGD) by-product was used to reconstruct the failed portion of a highway embankment. The construction process and the stability of the repaired embankment are examined. State Route 83 in Cumberland, Ohio has been damaged by a slow moving slide which has forced the Ohio Department of Transportation to repair the roadway several times. In the most recent repair FGD by-products obtained from American Electric Power`s Tidd PFBC plant were used to construct a wall through the failure plane to prevent further slippage. In order to evaluate the utility of using coal combustion by-products in this type of highway project the site was divided into three test sections. In the first repair section, natural soil removed form the slide area was recompacted and replaced according to standard ODOT construction practices. In the second section the natural soil was field mixed with the Tidd PFBC ash in approximately equal proportions. The third section was all Tidd ash. The three test sections were capped by a layer of compacted Tidd ash or crushed stone to provide a wearing surface to allow ODOT to open the roadway before applying a permanent asphalt surface. Measurement of slope movement as well as water levels and quality have begun at the site in order to evaluate long term project performance. The completion of this project should lead to increased acceptance of FGD materials in construction projects. Monetary savings will be realized in avoiding some of the disposal costs for the waste, as well as in the reduced reliance on alternative engineering materials.

    Clean-coal technology by-products are used in a highway embankment demonstration project. This research chronicles the procedures used in the process and analyzes the stability of a repaired highway embankment. The reconstructed slope is analyzed using an Intelligent Discussion Support System that was developed from a slope stability program. Water quality studies are performed and an instrumentation plan is suggested. The calculated factors of safety and the observed embankment performance give indications that the field demonstration project was a success. Long-term monitoring will be the best barometer for determining embankment gross movement and the future of FGD by-products as a stabilizing material.

EEAP surveys and identifies high energy users, analyzes and applies conservation technologies, and submits a study report to the Director of Engineering and Housing. The Energy Conservation Investment Program (ECIP), which retrofits existing facilities with insulation, and monitoring systems, is the foundation of EEAP. The Energy Conservation and Management Plan (ECAM) is designed to do for GOCO's (government owned, contractor operated plants) what ECIP does for army plants. A few specific conversion projects are listed. An energy awareness program includes seminars, workshops, displays, and brochures. The Facilities Energy RDTandS program insures that the Army will be able to rapidly utilize the latest state-of-the-art energy technology.

    The potential for conservation of natural gas is studied and the technical and economic feasibility and the implementation of ventures to produce such chemicals using carbon monoxide and hydrogen from byproduct gases are determined. A survey was performed of potential chemical products and byproduct gas sources. Byproduct gases from the elemental phosphorus and the iron and steel industries were selected for detailed study. Gas sampling, preliminary design, market surveys, and economic analyses were performed for specific sources in the selected industries. The study showed that production of methanol or ammonia from byproduct gas at the sites studied in the elemental phosphorus and the iron and steel industries is technically feasible but not economically viable under current conditions. Several other applications are identified as having the potential for better economics. The survey performed identified a need for an improved method of recovering carbon monoxide from dilute gases. A modest experimental program was directed toward the development of a permselective membrane to fulfill that need. A practical membrane was not developed but further investigation along the same lines is recommended. (MCW)

    The increasing role of coal as a source of energy in the 21st century will demand environmental and cost-effective strategies for the use of coal combustion by-products (CCBPs), mainly unburned carbon in fly ash. Unburned carbon is nowadays regarded as a waste product and its fate is mainly disposal, due to the present lack of efficient routes for its utilization. However, unburned carbon is a potential precursor for the production of adsorbent carbons, since it has gone through a devolatilization process while in the combustor, and therefore, only requires to be activated. Accordingly, the principal objective of this work was to characterize and utilize the unburned carbon in fly ash for the production of activated carbons. The unburned carbon samples were collected from different combustion systems, including pulverized utility boilers, a utility cyclone, a stoker, and a fluidized bed combustor. LOI (loss-on-ignition), proximate, ultimate, and petrographic analyses were conducted, and the surface areas of the samples were characterized by N2 adsorption isotherms at 77K. The LOIs of the unburned carbon samples varied between 21.79-84.52%. The proximate analyses showed that all the samples had very low moisture contents (0.17 to 3.39 wt %), while the volatile matter contents varied between 0.45 to 24.82 wt%. The elemental analyses show that all the unburned carbon samples consist mainly of carbon with very little hydrogen, nitrogen, sulfur and oxygen In addition, the potential use of unburned carbon as precursor for activated carbon (AC) was investigated. Activated carbons with specific surface area up to 1075m{sup 2}/g were produced from the unburned carbon. The porosity of the resultant activated carbons was related to the properties of the unburned carbon feedstock and the activation conditions used. It was found that not all the unburned carbon samples are equally suited for activation, and furthermore, their potential as activated carbons precursors could be

    Potomac Electric Power Company (PEPCo) Class F fly ash is the first material to be worked on in this project. A head sample was taken and a screen analysis performed. Each size fraction was evaluated for LOI content. Table 1 shows the distribution of the as-received material by size and LOI content. From the data, 80% of the as-received material is finer than 400 mesh and the LOI content goes from high at coarse fractions and decreases to a low at the finest size fraction. SEM chemical analysis identified the as-received fly ash to mainly consist of silica (46%), aluminum oxide (21%), and iron in various forms (16%). The high iron content presents an extreme case as compared to other fly ash samples we have evaluated previously. Its effect on product testing applications could identify physical and chemical limitations as product testing progresses. Because of the high iron content, it was realized that magnetic separation would be incorporated into the early part of the pilot plant flowsheet to remove magnetic iron and, hopefully, reduce the total iron content. More analytical data will be presented in the next reporting period.

    In analyzing gas samples taken from SF{sub 6}-insulated equipment it is generally assumed that the species in question remain stable throughout the sampling process and that the analyses accurately reflect the actual situation in the apparatus being tested. Frequently samples are shipped for analysis which may take from a few days to a few weeks of transit and storage time before testing is performed. Hence the sample must either remain stable over this time frame or at least change in a manner which is well understood in order to have reliable, accurate results. The same is also true for reference standards against which unknown samples are compared or calibrated. Failure to account for stability could lead to false conclusions which, for cases involving highly or moderately toxic compounds, could possibly result in higher exposure levels than expected. Many of the by-products of SF{sub 6} are known to hydrolyze in the gas phase, such as SF{sub 4} (sulfur tetrafluoride), SOF{sub 2} (thionyl fluoride), and SOF{sub 4} (thionyl tetrafluoride). Recently new processes involving decomposition on surfaces have been identified, making such parameters as surface to volume ratio, wall material, and adsorbed moisture, important to the overall sampling and analytical process. This paper discusses the stability by-products in relation to the sampling of SF{sub 6} equipment. 4 refs., 2 figs.

    Gas analysis provides a promising means for a diagnosis of gas-insulated equipment. Although many studies have been concentrated on SF[sub 6] gas decomposition, they were mostly related to the faults in GIS systems and not directly applicable to gas-insulated transformers, who have much complicated material structure. An experimental survey over decomposition by-products at various abnormal conditions was carried out by use of simulating models to develop a diagnostic method for gas-insulated transformers based on gas and ion chromatograph analyses. Major components characteristic to each abnormality, such SO[sub 2] on metal overheat, SO[sub 2]F[sub 2] on partial discharges, etc. were identified by the experiments.

    On September 30, 1993, the US Department of Energy - Morgantown Energy Technology Center (DOE-METC) and Southern Illinois University at Carbondale (SIUC) entered into a cooperative research agreement entitled {open_quotes}Management of Dry Flue Gas Desulfurization By-Products in Underground Mines{close_quotes} (DE-FC21-93MC30252). Under the agreement Southern Illinois University at Carbondale will develop and demonstrate two technologies for the placement of coal combustion residues in abandoned underground coal mines, and will assess the environmental impact of these technologies for the management of coal combustion by-products. The two technologies for the underground placement that will be developed and demonstrated are: (1) pneumatic placement, using virtually dry materials, and (2) hydraulic placement, using a {open_quotes}paste{close_quotes} mixture of materials with about 70% solids. Phase II of the overall program began April 1, 1996. The principal objective of Phase II is to develop and fabricate the equipment for placing the coal combustion by-products underground, and to conduct a demonstration of the technologies on the surface. Therefore, this quarter has been largely devoted to developing specifications for equipment components, visiting fabrication plants throughout Southern Illinois to determine their capability for building the equipment components in compliance with the specifications, and delivering the components in a timely manner.

    Designing an energy-efficient, affordable, and comfortable home is a lot easier thanks to a slime, easier to read booklet, the 2006 International Energy Conservation Code (IECC), published in March 2006. States, counties, and cities have begun reviewing the new code as a potential upgrade to their existing codes. Maintained under the public consensus process of the International Code Council, the IECC is designed to do just what its title says: promote the design and construction of energy-efficient homes and commercial buildings. Homes in this case means traditional single-family homes, duplexes, condominiums, and apartment buildings having three or fewer stories. The U.S. Department of Energy, which played a key role in proposing the changes that resulted in the new code, is offering a free training course that covers the residential provisions of the 2006 IECC.

  15. CHARACTERIZATION OF COAL COMBUSTION BY-PRODUCTS FOR THE RE-EVOLUTION OF MERCURY INTO ECOSYSTEMS

    SciTech Connect

    2005-03-01

    There is concern that mercury (Hg) in coal combustion by-products might be emitted into the environment during processing to other products or after the disposal/landfill of these by-products. This perception may limit the opportunities to use coal combustion by-products in recycle/reuse applications and may result in additional, costly disposal regulations. In this program, CONSOL conducted a comprehensive sampling and analytical program to include ash, flue gas desulfurization (FGD) sludge, and coal combustion by-products. This work is necessary to help identify potential problems and solutions important to energy production from fossil fuels. The program objective was to evaluate the potential for mercury emissions by leaching or volatilization, to determine if mercury enters the water surrounding an active FGD disposal site and an active fly ash slurry impoundment site, and to provide data that will allow a scientific assessment of the issue. Toxicity Characteristic Leaching Procedure (TCLP) test results showed that mercury did not leach from coal, bottom ash, fly ash, spray dryer/fabric filter ash or forced oxidation gypsum (FOG) in amounts leading to concentrations greater than the detection limit of the TCLP method (1.0 ng/mL). Mercury was detected at very low concentrations in acidic leachates from all of the fixated and more than half of the unfixated FGD sludge samples, and one of the synthetic aggregate samples. Mercury was not detected in leachates from any sample when deionized water (DI water) was the leaching solution. Mercury did not leach from electrostatic precipitator (ESP) fly ash samples collected during activated carbon injection for mercury control in amounts greater than the detection limit of the TCLP method (1.0 ng/mL). Volatilization tests could not detect mercury loss from fly ash, spray dryer/fabric filter ash, unfixated FGD sludge, or forced oxidation gypsum; the mercury concentration of these samples all increased, possibly due to

    This report represents the Final Technical Progress Report for Phase II of the overall program for a cooperative research agreement between the U.S. Department of Energy - MORGANTOWN Energy Technology Center (DOE-METC) and Southern Illinois University at Carbondale (SIUC). Under the agreement, SIUC will develop and demonstrate technologies for the handling, transport, and placement in abandoned underground coal mines of dry flue gas desulfurization by-products, such as fly ash, scrubber sludge, fluidized bed combustion by-products, and will assess the environmental impact of such underground placement. The overall program is divided into three (3) phases. Phase II of the program is primarily concerned with developing and testing the hardware for the actual underground placement demonstrations. Two technologies have been identified and hardware procured for full-scale demonstrations: (1) hydraulic placement, where coal combustion by-products (CCBs) will be placed underground as a past-like mixture containing about 70 to 75 percent solids; and (2) pneumatic placement, where CCBs will be placed underground as a relatively dry material using compressed air. 42 refs., 36 figs., 36 tabs.

    2009-03-31

    The work conducted in this project is an extension of the developments itemized in DE-FG-36-04GO14236. This program is designed to help the development of a biorefinery based around a raw sugar mill, which in Louisiana is an underutilized asset. Some technical questions were answered regarding the addition of a biomass to ethanol facility to existing sugar mills. The focus of this work is on developing technology to produce ethanol and valuable by-products from bagasse. Three major areas are addressed, feedstock storage, potential by-products and the technology for producing ethanol from dilute ammonia pre-treated bagasse. Sugar mills normally store bagasse in a simple pile. During the off season there is a natural degradation of the bagasse, due to the composting action of microorganisms in the pile. This has serious implications if bagasse must be stored to operate a bagasse/biorefinery for a 300+ day operating cycle. Deterioration of the fermentables in bagasse was found to be 6.5% per month, on pile storage. This indicates that long term storage of adequate amounts of bagasse for year-round operation is probably not feasible. Lignin from pretreatment seemed to offer a potential source of valuable by-products. Although a wide range of phenolic compounds were present in the effluent from dilute ammonia pretreatment, the concentrations of each (except for benzoic acid) were too low to consider for extraction. The cellulosic hydrolysis system was modified to produce commercially recoverable quantities of cellobiose, which has a small but growing market in the food process industries. A spin-off of this led to the production of a specific oligosaccharide which appears to have both medical and commercial implications as a fungal growth inhibitor. An alternate use of sugars produced from biomass hydrolysis would be to produce succinic acid as a chemical feedstock for other conversions. An organism was developed which can do this bioconversion, but the economics of

    The disposal of flue gas desulfurization (FGD) by-products has become a major concern as issues of emission cleansing and landfill costs continue to rise. Laboratory tests conducted at the Ohio State University have shown that dry FGD by-products possess certain engineering properties that have proven desirable in a number of construction uses. As a follow on to the laboratory program, a field investigation into engineering uses of dry FGD wastes was initiated. In the present work, an FGD by-product was used to reconstruct the failed portion of a highway embankment. The construction process and the stability of the repaired embankment are examined.

The study included laboratory tasks to develop measurement techniques for mercury and ATE releases, sample characterization, and release experiments. A field task was also performed to measure mercury releases at a field site. Samples of fly ash and flue gas desulfurization (FGD) materials were collected preferentially from full-scale coal-fired power plants operating both without and with mercury control technologies in place. In some cases, samples from pilot- and bench-scale emission control tests were included in the laboratory studies. Several sets of 'paired' baseline and test fly ash and FGD materials collected during full-scale mercury emission control tests were also included in laboratory evaluations. Samples from mercury emission control tests all contained activated carbon (AC) and some also incorporated a sorbent-enhancing agent (EA). Laboratory release experiments focused on measuring releases of mercury under conditions designed to simulate CCB exposure to water, ambient-temperature air, elevated temperatures, and microbes in both wet and dry conditions. Results of laboratory evaluations indicated that: (1) Mercury and sometimes selenium are collected with AC used for mercury emission control and, therefore, present at higher concentrations than samples collected without mercury emission controls present. (2) Mercury is stable on CCBs collected from systems both without and with mercury emission controls present under most conditions tested, with the exception of vapor-phase releases of mercury exposed to elevated temperatures. (3) The presence of carbon either from added AC or from unburned coal can result in mercury being

    The following report is a compilation of data on by-products/wastes from clean coal technologies, specifically integrated gasification combined cycle (IGCC) and pressurized fluidized-bed combustion (PFBC). DOE had two objectives in providing this information to EPA: (1) to familiarize EPA with the DOE CCT program, CCT by-products, and the associated efforts by DOE contractors in the area of CCT by-product management and (2) to provide information that will facilitate EPA's effort by complementing similar reports from industry groups, including CIBO (Council of Industrial Boiler Owners) and EEI USWAG (Edison Electric Institute Utility Solid Waste Activities Group). The EERC cooperated and coordinated with DOE CCT contractors and industry groups to provide the most accurate and complete data on IGCC and PFBC by-products, although these technologies are only now being demonstrated on the commercial scale through the DOE CCT program.

    2014-03-15

    Partial differential equations of the form divN=0, N{sub t}+curl M=0 involving two vector functions in R{sup 3} depending on t, x, y, z appear in different physical contexts, including the vorticity formulation of fluid dynamics, magnetohydrodynamics (MHD) equations, and Maxwell's equations. It is shown that these equations possess an infinite family of local divergence-type conservation laws involving arbitrary functions of space and time. Moreover, it is demonstrated that the equations of interest have a rather special structure of a lower-degree (degree two) conservation law in R{sup 4}(t,x,y,z). The corresponding potential system has a clear physical meaning. For the Maxwell's equations, it gives rise to the scalar electric and the vector magnetic potentials; for the vorticity equations of fluid dynamics, the potentialization inverts the curl operator to yield the fluid dynamics equations in primitive variables; for MHD equations, the potential equations yield a generalization of the Galas-Bogoyavlenskij potential that describes magnetic surfaces of ideal MHD equilibria. The lower-degree conservation law is further shown to yield curl-type conservation laws and determined potential equations in certain lower-dimensional settings. Examples of new nonlocal conservation laws, including an infinite family of nonlocal material conservation laws of ideal time-dependent MHD equations in 2+1 dimensions, are presented.

    1995-06-01

    As water utilities incorporate integrated resource planning in their management processes, it is necessary to incorporate the concept of externalities. This is particularly important as methods evolve of evaluating the costs and benefits of water conservation programs. The purpose of this article is to provide an introduction to the issues surrounding externalities, including their definition, methods of internalizing externalities, and a survey of ways to estimate costs and benefits of externalities. Although most discussions of externalities emphasize negative effects on the environment, this article will illustrate both positive and negative externalities associated with practicing water conservation.

    There is an instability in certain S.P.H. (Smoothed Particle Hydrodynamics method) material dynamics computations. Evidence from analyses and experiments suggests that the instabilities in S.P.H. are not removable with artificial viscosities. However, the analysis shows that a type of conservative smoothing does remove the instability. Also, numerical experiments, on certain test problems, show that SPHCS, and S.P.H. code with conservative smoothing, compares well in accuracy with computations based on the von Neumann-Richtmyer method.

    2005-09-30

    The US Department of Energy's National Energy Technology Laboratory (DOE/NETL) uses the term coal utilization by-products (CUBs) to describe the solid materials produced by the combustion or gasification of coal. The following general observations can be drawn from results of field tests that have been carried out thus far to determine whether new technologies for mercury emission control at coal power plants will affect the release of mercury from CUBs. There appears to be only minimal potential mercury release to the environment in typical disposal or utilization application for CUBs generated using ACI control technologies. There appears to be only minimal mercury release to the environment for CUBs generated using wet FGD control technologies. The amount of mercury leached from CUBs samples tested is significantly lower than the federal drinking water standards and water quality criteria for the protection of aquatic life. 3 figs., 2 tabs.

  11. Use of clean coal technology by-products as agricultural liming techniques

    SciTech Connect

    Stehouwer, R.C.; Sutton, P.; Dick, W.A.

    1995-03-01

    Dry flue gas desulfurization (FGD) by-products are mixtures of coal fly-ash, anhydrite (CaCO{sub 4}), and unspent lime- or limestone-based sorbent. Dry FGD by-products frequently have neutralizing values greater than 50% CaCO{sub 3} equivalency and thus have potential for neutralizing acidic soils. Owing to the presence of soluble salts and various trace elements, however, soil application of dry FGD by-products may have adverse effects on plant growth and soil quality. The use of a dry FGD by-product as a limestone substitute was investigated in a field study on three acidic agricultural soils (pH 4.6, 4.8, and 5.8) in eastern Ohio. The by-product (60% CaCO{sub 3} equivalency) was applied in September, 1992, at rates of 0, 0.5, 1.0, and 2.0 times the lime requirement of the soils, and alfalfa (Medicago sativa L.) and corn (Zea mays L.) were planted. Soils were sampled immediately after FGD application and three more times every six months thereafter. Samples were analyzed for pH and water soluble concentrations of 28 elements. Soil pH was increased by all FGD rates in the zone of incorporation (0--10 cm), with the highest rates giving a pH slightly above 7. Within one year pH increases could be detected at depths up to 30 cm. Calcium, Mg, and S increased, and Al, Mn, and Fe decreased with increasing dry FGD application rates. No trace element concentrations were changed by dry FGD application except B which was increased in the zone of incorporation. Dry FGD increased alfalfa yield on all three soils, and had no effect on corn yield. No detrimental effects on soil quality were observed.

  12. Energy conservation is a waste

    SciTech Connect

    Inhaber, H.

    1998-07-01

    Energy conservation is virtually always a bust. Governments around the world continually trot out new schemes to reduce energy use and promote efficiency. The prime American example of this futility is government regulation of automobile gas mileage. Prompted by the Arab oil embargo of 1973, Congress mandated a doubling of gas mileage. What happened? Gasoline consumption rose from 1973 to the 1990s, as the roads were flooded with energy-efficient cars. Huge sport-utility vehicles crowd parking lots, also thanks to more efficient engines. Conservation fails because it takes no account of economics of human nature. The combination of greater engine efficiency and rising disposable income has produced a true golden age of motoring. In the same way, what is saved by installing special light bulbs is often wasted on new hot tubs, exterior lighting and a host of other energy uses, as homeowners assume that their electric bills will drop off substantially. In spite of these and dozens of other clear failures, the claims for conservation to solve virtually all the national energy dilemmas continue. Few if any are valid. While each of us can reduce energy use in one or two areas, one finds that the nation gradually uses more.

In an effort to find secondary uses for the elemental sulfur, and simultaneously produce a material which could be used to encapsulate, and reduce the dispersion of harmful contaminants into the environment, BNL evaluated the use of the sulfur polymer cement (SPC) produced from by-product sulfur in Kazakhstan. This thermoplastic binder material forms a durable waste form with low leaching properties and is compatible with a wide range of waste types. Several hundred kilograms of Kazakhstan sulfur were shipped to the US and converted to SPC (by reaction with 5 wt% organic modifiers) for use in this study. A phosphogypsum sand waste generated in Kazakhstan during the purification of phosphate fertilizer was selected for treatment. Waste loadings of 40 wt% were easily achieved. Waste form performance testing included compressive strength, water immersion, and Accelerated Leach Testing.

    2005-07-15

    This final project report presents the results of a research program conducted at The Ohio State University from January 3, 2000 to June 30, 2005 to investigate the long-term use of stabilized flue gas desulfurization (FGD) materials in the construction of low permeability liners for ponds and wetlands. The objective of the research program was to establish long-term field-verified time-dependent relationships for the performance of liners constructed from stabilized FGD byproducts generated in Ohio. The project objective was accomplished with a coordinated program of testing and analyzing small-scale laboratory specimens under controlled conditions, mediumscale wetland experiments, and monitoring of a full-scale FGD-lined pond facility. Although the specific uses directly addressed by this report include liners for surface impoundments, the results presented in this study are also useful in other applications especially in the design of daily covers and liners for landfills, seepage cutoff walls and trenches, and for nutrient retention and pollution mitigation wetlands. The small-scale laboratory tests and monitoring of the full-scale FGD lined facility (capacity of one million gallons) shows that stabilized FGD materials can be used as low permeability liners in the construction of water and manure holding ponds. Actual long-term permeability coefficients in the range of 10-7 cm/sec (3 x 10-9 ft/sec) can be obtained in the field by compacting lime and fly ash enriched stabilized FGD materials. Leachate from the FGD material meets Ohios non-toxic criteria for coal combustion by-products, and for most potential contaminants the national primary and secondary drinking water standards are also met. The low permeability non-toxic FGD material investigated in this study poses very minimal risks, if any, for groundwater contamination. The FGD wetland experiments indicated no significant differences in phosphorus retention between the clay and FGD

    2014-08-15

    A systematic study of energy conservation for extended magnetohydrodynamic models that include Hall terms and electron inertia is performed. It is observed that commonly used models do not conserve energy in the ideal limit, i.e., when viscosity and resistivity are neglected. In particular, a term in the momentum equation that is often neglected is seen to be needed for conservation of energy.

  7. CHARACTERIZATION OF COAL COMBUSTION BY-PRODUCTS FOR THE RE-EVOLUTION OF MERCURY INTO ECOSYSTEMS

    SciTech Connect

    A.M. Schwalb; J.A. Withum

    2003-07-01

    There is some concern that mercury (Hg) in coal combustion by-products can be emitted into the environment during processing to other products, by volatilization or by dissolution into groundwater. This perception may limit the opportunities to use coal combustion by-products after disposal in recycle/reuse applications. In this program, CONSOL Energy Inc., Research & Development (CONSOL) is conducting a comprehensive sampling and analytical program to address this concern. The objective is to evaluate the potential for Hg emissions by leaching or volatilization, and to provide data that will allow a scientific assessment of the issue. The main activities for this quarter were: the re-volatilization study was continued; the literature review was updated; and the ground water study was continued.

  12. Equity implications of utility energy conservation programs

    SciTech Connect

    Sutherland, R.J.

    1994-03-15

    This paper uses the Residential Energy Consumption Survey undertaken by the Energy Information Administration in 1990 to estimate the statistical association between household income and participation in electric utility energy conservation programs and the association between participation and the electricity consumption. The results indicate that utility rebates, energy audits, load management programs and other conservation measures tend to be undertaken at greater frequency by high income households than by low income households. Participants in conservation programs tend to occupy relatively new and energy efficient residences and undertake conservation measures other than utility programs, which suggests that utility sponsored programs are substitutes for other conservation investments. Electricity consumption during 1990 is not significantly less for households participating in utility programs than for nonparticipants, which also implies that utility conservation programs are displacing other conservation investments. Apparently, utility programs are not avoiding costs of new construction and instead are transferring wealth, particularly to high income participating households.

    1992-01-01

    The Bonneville Power Administration (Bonneville) has identified 101 plants in the Pacific Northwest that account for 80% of the region's industrial electricity consumption. These plants offer a precise target for a conservation program. PNL determined that most of these 101 plants were represented by 11 major industries. We then reviewed 36 major conservation technologies used in these 11 industrial settings to determine their potential environmental impacts. Energy efficiency technologies designed for industrial use may result in direct or indirect environmental impacts. Effects may result from the production of the conservation measure technology, changes in the working environment due to different energy and material requirements, or changes to waste streams. Industry type, work-place conditions, worker training, and environmental conditions inside and outside the plant are all key variables that may affect environmental outcomes. To address these issues this report has three objectives: Describe potential conservation measures that Bonneville may employ in industrial programs and discuss potential primary impacts. Characterize industrial systems and processes where the measure may be employed and describe general environmental issues associated with each industry type. Review environmental permitting, licensing, and other regulatory actions required for industries and summarize the type of information available from these sources for further analysis.

    On September 30, 1993, the US Department of Energy, Morgantown Energy Technology Center and Southern Illinois University at Carbondale (SIUC) entered into a cooperative agreement entitled ``Management of Dry Flue Gas Desulfurization By-Products in Underground Mines`` (DE-FC21-93MC30252). Under the agreement, Southern Illinois University at Carbondale will develop and demonstrate several technologies for the placement of coal combustion residues in abandoned coal mines, and will assess the environmental impact of such underground residues placement. The major event during the quarter was the demonstration of the SEEC, Inc. technology for loading and transporting coal combustion residues in the SEEC developed Collapsible Intermodal Containers (CIC). The demonstration was held on November 17, 1994, at the Illinois Power Company Baldwin power plant, and was attended by about eighty (80) invited guest. Also during the quarter meetings were held with Peabody Coal Company officials to finalize the area in the Peabody No. 10 mine to be used for the placement of coal combustion residues. Work under the Materials Handling and Systems Economics area continued, particularly in refining the costs and systems configuration and in economic evaluation of various systems using equipment leasing rather than equipment purchases. Likewise, work progressed on residues characterization, with some preparations being made for long-term testing.

    The objective of this project was to develop and demonstrate two technologies for the placement of coal combustion by-products in abandoned underground coal mines, and to assess the environmental impact of these technologies for the management of CCB materials. The two technologies for the underground placement that were to be developed and demonstrated are: (1) pneumatic placement using virtually dry CCB products, and (2) hydraulic placement using a paste mixture of CCB products with about 70% solids. The period covered by this report is the second quarter of Phase 3 of the overall program. During this period over 8,000 tons of CCB mixtures was injected using the hydraulic paste technology. This amount of material virtually filled the underground opening around the injection well, and was deemed sufficient to demonstrate fully the hydraulic injection technology. By the end of this quarter about 2,000 tons of fly ash had been placed underground using the pneumatic placement technology. While the rate of injection of about 50 tons per hour met design criteria, problems were experienced in the delivery of fly ash to the pneumatic demonstration site. The source of the fly ash, the Archer Daniels Midland Company power plant at Decatur, Illinois is some distance from the demonstration site, and often sufficient tanker trucks are not available to haul enough fly ash to fully load the injection equipment. Further, on some occasions fly ash from the plant was not available. The injection well was plugged three times during the demonstration. This typically occurred due to cementation of the FBC ash in contact with water. After considerable deliberations and in consultation with the technical project officer, it was decided to stop further injection of CCB`s underground using the developed pneumatic technology.

  9. Gas treatment and by-products recovery of Thailand`s first coke plant

    SciTech Connect

    Diemer, P.E.; Seyfferth, W.

    1997-12-31

    Coke is needed in the blast furnace as the main fuel and chemical reactant and the main product of a coke plant. The second main product of the coke plant is coke oven gas. During treatment of the coke oven gas some coal chemicals like tar, ammonia, sulphur and benzole can be recovered as by-products. Since the market prices for these by-products are rather low and often erratic it does not in most cases justify the investment to recover these products. This is the reason why modern gas treatment plants only remove those impurities from the crude gas which must be removed for technical and environmental reasons. The cleaned gas, however, is a very valuable product as it replaces natural gas in steel work furnaces and can be used by other consumers. The surplus can be combusted in the boiler of a power plant. A good example for an optimal plant layout is the new coke oven facility of Thai Special Steel Industry (TSSI) in Rayong. The paper describes the TSSI`s coke oven gas treatment plant.

    An environmental chamber was constructed to measure the mercury flux from coal utilization by-product (CUB) samples. Samples of fly ash, FGD gypsum, and wallboard made from FGD gypsum were tested under both dark and illuminated conditions with or without the addition of water to the sample. Mercury releases varied widely, with 7- day experiment averages ranging from -6.8 to 73 ng/m(2) h for the fly ash samples and -5.2 to 335 ng/m(2) h for the FGD/wallboard samples. Initial mercury content, fly ash type, and light exposure had no observable consistent effects on the mercury flux. For the fly ash samples, the effect of a mercury control technology was to decrease the emission. For three of the four pairs of FGD gypsum and wallboard samples, the wallboard sample released less (or absorbed more) mercury than the gypsum.

    1991-01-01

    The primary objectives of the Caribbean Tourist Facilities (CTF) project were to develop and publish materials and conduct workshops on solar energy and conservation technologies that would directly address the needs and interests of tourist facilities in the Caribbean basin. Past contacts with the Caribbean and US tourist industries indicated that decision-makers remained unconvinced that renewable technologies could have a significant impact on development and operation costs or that renewable energy products and services suited their needs. In order to assure that the materials and programs developed were responsive to the Caribbean tourist industry and US conservation and renewable energy industries, marketing research with potential end users and the organizations and associations that serve those users was included as an underlying task in the project. The tasks outlined in the CTF Statement of Work included conference planning, gathering of field data, development of educational materials, and conduct of workshop(s). In addition to providing a chronicle of the fulfillment of those tasks, this final report includes suggestions for distributing the documents developed during the project, venues for future workshops, and other technology transfer and market influence strategies. 3 refs.

    Preliminary environmental risk assessment on the FGD by-products to be placed underground is virtually complete. The initial mixes for pneumatic and hydraulic placement have been selected and are being subject to TCLP, ASTM, and modified SLP shake tests as well as ASTM column leaching. Results of these analyses show that the individual coal combustion residues, and the residues mixes, are non-hazardous in character. Based on available information, including well logs obtained from Peabody Coal Company, a detailed study of the geology of the placement site was completed. The study shows that the disposal site in the abandoned underground mine workings at depths of between 325 and 375 feet are well below potable groundwater resources. This, coupled with the benign nature of the residues and residues mixtures, should alleviate any concern that the underground placement will have adverse effects on groundwater resources. Seven convergence stations were installed in the proposed underground placement area of the Peabody Coal Company No. 10 mine. Several sets of convergence data were obtained from the stations. A study of materials handling and transportation of coal combustion residues from the electric power plant to the injection site has been made. The study evaluated the economics of the transportation of coal combustion residues by pneumatic trucks, by pressure differential rail cars, and by SEEC, Inc. collapsible intermodal containers (CICs) for different annual handling rates and transport distances. The preliminary physico-chemical characteristics and engineering properties of various FBC fly ash-spent bed mixes have been determined, and long-term studies of these properties are continuing.

    On September 30, 1993, the U.S. Department of Energy-Morgantown Energy Technology Center and Southern Illinois University at Carbondale (SIUC) entered into a cooperative research agreement entitled {open_quotes}Management of Dry Flue Gas Desulfurization By-Products in Underground Mines{close_quotes} (DE-FC21-93MC30252). Under the agreement Southern Illinois University at Carbondale will develop and demonstrate several technologies for the placement of coal combustion residues in abandoned coal mines, and will assess the environmental impact of such underground residues placement. Previous quarterly Technical Progress Reports have set forth the specific objectives of the program, and a discussion of these is not repeated here. Rather, this report discusses the technical progress made during the period April 1 - June 30, 1995. A final topical report on the SEEC, Inc. demonstration of its technology for the transporting of coal combustion residues was completed during the quarter, although final printing of the report was accomplished early in July, 1995. The SEEC technology involves the use of Collapsible Intermodal Containers (CIC`s) developed by SEEC, and the transportation of such containers - filled with fly ash or other coal combustion residues - on rail coal cars or other transportation means. Copies of the final topical report, entitled {open_quotes}The Development and Testing of Collapsible Intermodal Containers for the Handling and Transport of Coal Combustion Residues{close_quotes} were furnished to the Morgantown Energy Technology Center. The Rapid Aging Test colums were placed in operation during the quarter. This test is to determine the long-term reaction of both the pneumatic and hydraulic mixtures to brine as a leaching material, and simulates the conditions that will be encountered in the actual underground placement of the coal combustion residues mixtures. The tests will continue for about one year.

  7. Scrap metal management issues associated with naturally occurring radioactive material

    1995-08-01

    Certain industrial processes sometimes generate waste by-products that contain naturally occurring radioactive material (NORM) at elevated concentrations. Some industries, including the water treatment, geothermal energy, and petroleum industries, generate scrap metal that may be contaminated with NORM wastes. Of these three industries, the petroleum industry probably generates the largest quantity of NORM-contaminated equipment, conservatively estimated at 170,000 tons per year. Equipment may become contaminated when NORM-containing scale or sludge accumulates inside water-handling equipment. The primary radionuclides of concern in these NORM wastes are radium-226 and radium-228. NORM-contaminated equipment generated by the petroleum industry currently is managed several ways. Some equipment is routinely decontaminated for reuse; other equipment becomes scrap metal and may be disposed of by burial at a licensed landfill, encapsulation inside the wellbore of an abandoned well, or shipment overseas for smelting. In view of the increased regulatory activities addressing NORM, the economic burden of managing NORM-contaminated wastes, including radioactive scrap metal, is likely to continue to grow. Efforts to develop a cost-effective strategy for managing radioactive scrap metal should focus on identifying the least expensive disposition options that provide adequate protection of human health and the environment. Specifically, efforts should focus on better characterizing the quantity of radioactive scrap available for recycle or reuse, the radioactivity concentration levels, and the potential risks associated with different disposal options.

  8. Assessment of the industrial energy-conservation program. Final report of the Committee on Assessment of the Industrial Energy Conservation Program

    SciTech Connect

    1982-01-01

    Industrial operations in the United States account for some 37% of the nation's consumptions of energy. It has been estimated that this figure will increase to 50% by 1990 unless appropriate industrial energy conservation measures are adopted. However, such measures are difficult to implement in spite of the potential of various existing, emerging, and advanced technologies that can be applied to the problem. Specifically, the application of many industrial energy conservation measures entails high economic, technological, and institutional risks and uncertainties that constrain industries from adopting such measures. Accordingly, in 1975 the federal government started a program designed to mitigate these risks and uncertainties via government-industry partnership arrangements in the interests of national energy conservation. An important element of this program is the Industrial Energy Conservation Program in the Federal Department of Energy (DOE). In June 1980, DOE asked the National Materials Advisory Board, a unit of the National Academy of Sciences-National Research Council, to form a study committee to assess the effectiveness of the Industrial Energy Conservation Program. The committee concluded that federal support embodied in the DOE program, present and planned, is important to conserving additional industrial energy. However, the committee also concluded that the program needs various improvements in project selection and management and in transfer of results to industry. The committee's findings and recommendations and the results of the deliberation of the committee's three panels, a special report on heat and power, and a report on the visit by four members of the committee to Japan are presented.

    Previously the authors have used earthworm and plant bioassays to evaluate the toxicity of nitroaromatic ammunition by-products. In the present study, they investigated the uptake, metabolism and possible bioaccumulation of these compounds in earthworms and plants. Earthworms were maintained on artificial soil supplemented with {sup 14}[C] trinitrobenzene (TNB). The authors also studied the translocation, metabolism and bioaccumulation of {sup 14}[C] 1,3-dinitrobenzene (DNB) by germinating oat and lettuce seeds planted on artificial soil. Acetone extracts of tissue and gut contents of earthworms exposed to TNB for different intervals contained only a small fraction of the original radioactivity, which did not increase with time. The radioactivity extracted from earthworms co-eluted with 1,3-dinitroaniline (DNAN) on HPLC and the amount of radioactivity decreased with time. In the DNB plant studies, five day old oat seedlings accumulated 17% of {sup 14}[C] radioactivity. HPLC of acetone extracts revealed unidentified radioactive peaks but DNB radioactivity was not detected. The radioactivity from butanol extracts of both oats and lettuce coeluted with aniline and 3-nitroaniline and the radioactivity increased with time. These results suggest that oats and lettuce bioaccumulate DNB metabolites, which might result in the transfer of toxicants to herbivores.

    Various policies and programs have been created to promote energy conservation in Asia. Energy conservation centers, energy conservation standards and labeling, commercial building codes, industrial energy use regulations, and utility demand-side management (DSM) are but a few of them. This article attempts to analyze the roles of these different policies and programs in seven typical Asian countries: China, Indonesia, Japan, Pakistan, South Korea, the Philippines, and Thailand. The conclusions show that the two most important features behind the success policies and programs are (1) government policy support and (2) long-run self-sustainability of financial support to the programs.

    This final project report presents the results of a research program conducted at The Ohio State University from October 1, 1996 to March 31, 2000 to investigate the use of stabilized flue gas desulfurization (FGD) materials in the construction of low permeability liners. The objective of the research program was to establish field-verified time-dependent relationships for the performance of liners constructed from stabilized FGD by-products generated in Ohio. The project objective was accomplished with a coordinated program of testing and analyzing small scale laboratory specimens under controlled conditions, medium-scale wetland mesocosms, and a full-scale pond facility. Although the specific uses directly addressed by this report include liners for surface impoundments, the results presented in this study are also useful in other applications including design of daily cover and liners for landfills, seepage cutoff walls and trenches and for nutrient retention and pollution mitigation wetlands. The small scale laboratory tests, medium scale mesocosm wetland experiments, and construction and monitoring of a full-scale FGD lined facility (capacity of one million gallons) shows that stabilized FGD materials can be used as low permeability liners in the construction of water and manure holding ponds, and constructed wetlands for wastewater treatment. Actual permeability coefficients in the range of 10-7 cm/sec (3 x 10-9 ft/sec) can be obtained in the field by properly compacting lime and fly ash enriched stabilized FGD materials. Leachate from the FGD material meets Ohio’s non-toxic criteria for coal combustion by-products, and for most potential contaminants the national primary and secondary drinking water standards are also met. The low permeability non-toxic FGD material investigated in this study poses very minimal risks, if any, for groundwater contamination. Constructed FGD-lined wetlands offer the opportunity for increased phosphorous

    Sequential leaching experiments on coal utilization by-products (CUB) were coupled with chemical and strontium (Sr) isotopic analyses to better understand the influence of coal type and combustion processes on CUB properties and the release of elements during interaction with environmental waters during disposal. Class C fly ash tended to release the highest quantity of minor and trace elementsincluding alkaline earth elements, sodium, chromium, copper, manganese, lead, titanium, and zincduring sequential extraction, with bottom ash yielding the lowest. Strontium isotope ratios ({sup 87}Sr/{sup 86}Sr) in bulk-CUB samples (total dissolution of CUB) are generally higher in class F ash than in class C ash. Bulk-CUB ratios appear to be controlled by the geologic source of the mineral matter in the feed coal, and by Sr added during desulfurization treatments. Leachates of the CUB generally have Sr isotope ratios that are different than the bulk value, demonstrating that Sr was not isotopically homogenized during combustion. Variations in the Sr isotopic composition of CUB leachates were correlated with mobility of several major and trace elements; the data suggest that arsenic and lead are held in phases that contain the more radiogenic (high-{sup 87}Sr/{sup 86}Sr) component. A changing Sr isotope ratio of CUB-interacting waters in a disposal environment could forecast the release of certain strongly bound elements of environmental concern. This study lays the groundwork for the application of Sr isotopes as an environmental tracer for CUBwater interaction.

    Three industrial by-products (fly ash, phosphogypsum and blast furnace slag), were evaluated for their potential re-use as soil amendments to reduce methane (CH{sub 4}) emission resulting from rice cultivation. In laboratory incubations, CH{sub 4} production rates from anoxic soil slurries were significantly reduced at amendment levels of 0.5%, 1%, 2% and 5% (wt wt{sup -1}), while observed CO{sub 2} production rates were enhanced. The level of suppression in methane production was the highest for phosphogypsum, followed by blast slag and then fly ash. In the greenhouse experiment, CH{sub 4} emission rates from the rice planted potted soils significantly decreased with the increasing levels (2-20 Mg ha{sup -1}) of the selected amendments applied, while rice yield simultaneously increased compared to the control treatment. At 10 Mg ha{sup -1} application level of the amendments, total seasonal CH{sub 4} emissions were reduced by 20%, 27% and 25%, while rice grain yields were increased by 17%, 15% and 23% over the control with fly ash, phosphogypsum, and blast slag amendments, respectively. The suppression of CH{sub 4} production rates as well as total seasonal CH{sub 4} flux could be due to the increased concentrations of active iron, free iron, manganese oxides, and sulfate in the amended soil, which acted as electron acceptors and controlled methanogens' activity by limiting substrates availability. Among the amendments, blast furnace slag and fly ash contributed mainly to improve the soil nutrients balance and increased the soil pH level towards neutral point, but soil acidity was developed with phosphogypsum application. Conclusively, blast slag among the selected amendments would be a suitable soil amendment for reducing CH{sub 4} emissions as well as sustaining rice productivity.

    The Energy Conservation Projects to benefit the railroad industry using the Norfolk Southern Company as a model for the railroad industry has five unique tasks which are in areas of importance within the rail industry, and specifically in the area of energy conservation. The NIU Engineering and Technology research team looked at five significant areas in which research and development work can provide unique solutions to the railroad industry in energy the conservation. (1) Alternate Fuels - An examination of various blends of bio-based diesel fuels for the railroad industry, using Norfolk Southern as a model for the industry. The team determined that bio-diesel fuel is a suitable alternative to using straight diesel fuel, however, the cost and availability across the country varies to a great extent. (2) Utilization of fuel cells for locomotive power systems - While the application of the fuel cell has been successfully demonstrated in the passenger car, this is a very advanced topic for the railroad industry. There are many safety and power issues that the research team examined. (3) Thermal and emission reduction for current large scale diesel engines - The current locomotive system generates large amount of heat through engine cooling and heat dissipation when the traction motors are used to decelerate the train. The research team evaluated thermal management systems to efficiently deal with large thermal loads developed by the operating engines. (4) Use of Composite and Exotic Replacement Materials - Research team redesigned various components using new materials, coatings, and processes to provide the needed protection. Through design, analysis, and testing, new parts that can withstand the hostile environments were developed. (5) Tribology Applications - Identification of tribology issues in the Railroad industry which play a significant role in the improvement of energy usage.

    The oil embargo in the winter of 1973 covered the nation with a serious energy crisis. Although the ''gas lines'' have subsided, sky-rocketing fuel costs and diminishing energy supplies linger on. Projected U.S. energy demands indicate normal energy requirements over a normal growth rate. However, when compared with the projected U.S. energy supplies, a very significant energy deficit may exist in the near future. Although coal and nuclear show substantial potential as energy sources, it is unlikely that they will fill the gap between energy demands and the gas and oil supplies. In view of the Three-Mile Island nuclear incident, and cutbacks in the state of Washington, it is doubtful that the 13% contribution to the energy supply in the part of nuclear power will ever materialize. Although coal supplies are very abundant, the development of coal technology will not meet the next decade's energy requirements as it is indicated by the fact that coal is supplying far less energy than forecasted by the government.

  5. Controls on terrestrial carbon feedbacks by productivity versus turnover in the CMIP5 Earth System Models

    Koven, C. D.; Chambers, J. Q.; Georgiou, K.; Knox, R.; Negron-Juarez, R.; Riley, W. J.; Arora, V. K.; Brovkin, V.; Friedlingstein, P.; Jones, C. D.

    2015-09-07

    To better understand sources of uncertainty in projections of terrestrial carbon cycle feedbacks, we present an approach to separate the controls on modeled carbon changes. We separate carbon changes into four categories using a linearized, equilibrium approach: those arising from changed inputs (productivity-driven changes), and outputs (turnover-driven changes), of both the live and dead carbon pools. Using Coupled Model Intercomparison Project Phase 5 (CMIP5) simulations for five models, we find that changes to the live pools are primarily explained by productivity-driven changes, with only one model showing large compensating changes to live carbon turnover times. For dead carbon pools, themore » situation is more complex as all models predict a large reduction in turnover times in response to increases in productivity. This response arises from the common representation of a broad spectrum of decomposition turnover times via a multi-pool approach, in which flux-weighted turnover times are faster than mass-weighted turnover times. This leads to a shift in the distribution of carbon among dead pools in response to changes in inputs, and therefore a transient but long-lived reduction in turnover times. Since this behavior, a reduction in inferred turnover times resulting from an increase in inputs, is superficially similar to priming processes, but occurring without the mechanisms responsible for priming, we call the phenomenon "false priming", and show that it masks much of the intrinsic changes to dead carbon turnover times as a result of changing climate. These patterns hold across the fully coupled, biogeochemically coupled, and radiatively coupled 1 % yr−1 increasing CO2 experiments. We disaggregate inter-model uncertainty in the globally integrated equilibrium carbon responses to initial turnover times, initial productivity, fractional changes in turnover, and fractional changes in productivity. For both the live and dead carbon pools, inter

  7. SUSTAINABLE DEVELOPMENT IN KAZAKHASTAN: USING OIL AND GAS PRODUCTION BY-PRODUCT SULFUR FOR COST-EFFECTIVE SECONDARY END-USE PRODUCTS.

    SciTech Connect

    KALB, P.D.; VAGIN, S.; BEALL, P.W.; LEVINTOV, B.L.

    2004-09-25

    The Republic of Kazakhstan is continuing to develop its extensive petroleum reserves in the Tengiz region of the northeastern part of the Caspian Sea. Large quantities of by-product sulfur are being produced as a result of the removal of hydrogen sulfide from the oil and gas produced in the region. Lack of local markets and economic considerations limit the traditional outlets for by-product sulfur and the buildup of excess sulfur is a becoming a potential economic and environmental liability. Thus, new applications for re-use of by-product sulfur that will benefit regional economies including construction, paving and waste treatment are being developed. One promising application involves the cleanup and treatment of mercury at a Kazakhstan chemical plant. During 19 years of operation at the Pavlodar Khimprom chlor-alkali production facility, over 900 tons of mercury was lost to the soil surrounding and beneath the buildings. The Institute of Metallurgy and Ore Benefication (Almaty) is leading a team to develop and demonstrate a vacuum-assisted thermal process to extract the mercury from the soil and concentrate it as pure, elemental mercury, which will then be treated using the Sulfur Polymer Stabilization/Solidification (SPSS) process. The use of locally produced sulfur will recycle a low-value industrial by-product to treat hazardous waste and render it safe for return to the environment, thereby helping to solve two problems at once. SPSS chemically stabilizes mercury to mercuric sulfide, which has a low vapor pressure and low solubility, and then physically encapsulates the material in a durable, monolithic solid sulfur polymer matrix. Thus, mercury is placed in a solid form very much like stable cinnabar, the form in which it is found in nature. Previous research and development has shown that the process can successfully encapsulate up to 33 wt% mercury in the solid form, while still meeting very strict regulatory standards for leachable mercury (0.025 mg

  13. Potential for energy conservation in the cement industry

    SciTech Connect

    Garrett-Price, B.A.

    1985-02-01

    This report assesses the potential for energy conservation in the cement industry. Energy consumption per ton of cement decreased 20% between 1972 and 1982. During this same period, the cement industry became heavily dependent on coal and coke as its primary fuel source. Although the energy consumed per ton of cement has declined markedly in the past ten years, the industry still uses more than three and a half times the fuel that is theoretically required to produce a ton of clinker. Improving kiln thermal efficiency offers the greatest opportunity for saving fuel. Improving the efficiency of finish grinding offers the greatest potential for reducing electricity use. Technologies are currently available to the cement industry to reduce its average fuel consumption per ton by product by as much as 40% and its electricity consumption per ton by about 10%. The major impediment to adopting these technologies is the cement industry's lack of capital as a result of low or no profits in recent years.

    Bakosi, J.; Ristorcelli, J. R.

    2014-03-04

    We investigate coupled stochastic differential equations governing N non-negative continuous random variables that satisfy a conservation principle. In various fields a conservation law requires that a set of fluctuating variables be non-negative and (if appropriately normalized) sum to one. As a result, any stochastic differential equation model to be realizable must not produce events outside of the allowed sample space. We develop a set of constraints on the drift and diffusion terms of such stochastic models to ensure that both the non-negativity and the unit-sum conservation law constraint are satisfied as the variables evolve in time. We investigate the consequencesmore » of the developed constraints on the Fokker-Planck equation, the associated system of stochastic differential equations, and the evolution equations of the first four moments of the probability density function. We show that random variables, satisfying a conservation law constraint, represented by stochastic diffusion processes, must have diffusion terms that are coupled and nonlinear. The set of constraints developed enables the development of statistical representations of fluctuating variables satisfying a conservation law. We exemplify the results with the bivariate beta process and the multivariate Wright-Fisher, Dirichlet, and Lochner’s generalized Dirichlet processes.« less

    This report summarizes the accomplishments toward project goals during the first six months of the second year of the project to assess the properties and performance of coal based products. These products are in the gasoline, diesel and fuel oil range and result from coal based jet fuel production from an Air Force funded program. Specific areas of progress include generation of coal based material that has been fractionated into the desired refinery cuts, acquisition and installation of a research gasoline engine, and modification of diesel engines for use in evaluating diesel produced in the project. The desulfurization of sulfur containing components of coal and petroleum is being studied so that effective conversion of blended coal and petroleum streams can be efficiently converted to useful refinery products. Equipment is now in place to begin fuel oil evaluations to assess the quality of coal based fuel oil. Coal samples have procured and are being assessed for cleaning prior to use in coking studies.
