Carbon nanotube (CNT) gas sensors for emissions from fossil fuel burning  

Science Journals Connector (OSTI)

Abstract Fossil fuels endow wide applications in industrial, transportation, and power generation sectors. However, smoke released by burning fossil fuels contains toxic gases, which pollutes the environment and severely affects human health. Carbon nanotubes (CNTs) are potential material for gas sensors due to their high structural porosity and high specific surface area. Defects present on the CNT sidewalls and end caps facilitate adsorption of gas molecules. The chemical procedures adopted to purify and disperse carbon nanotubes create various chemical groups on their surface, which further enhance the adsorption of gas molecules and thus improve the sensitivity of CNTs. Present review focuses on CNT chemiresistive gas sensing mechanisms, which make them suitable for the development of next generation sensor technology. The resistance of carbon nanotubes decreases when oxidizing gas molecules adsorb on their surface, whereas, adsorption of reducing gas molecules results in increasing the resistance of CNTs. Sensing ability of carbon nanotubes for the gases namely, NO, NO2, CO, CO2 and SO2, released on burning of fossil fuels is reviewed. This review provides basic understanding of sensing mechanisms, creation of adsorption sites by chemical processes and charge transfer between adsorbed gas molecules and surface of CNTs. In addition, useful current update on research and development of CNT gas sensors is provided.

Partial replacement of fossil fuel in a cement plant: Risk assessment for the population living in the neighborhood  

Science Journals Connector (OSTI)

In cement plants, the substitution of traditional fossil fuels not only allows a reduction of CO2, but it also means to check-out residual materials, such as sewage sludge or municipal solid wastes (MSW), which should otherwise be disposed somehow/somewhere. In recent months, a cement plant placed in Alcanar (Catalonia, Spain) has been conducting tests to replace fossil fuel by refuse-derived fuel (RDF) from MSW. In July 2009, an operational test was progressively initiated by reaching a maximum of partial substitution of 20% of the required energy. In order to study the influence of the new process, environmental monitoring surveys were performed before and after the RDF implementation. Metals and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) were analyzed in soil, herbage, and air samples collected around the facility. In soils, significant decreases of PCDD/F levels, as well as in some metal concentrations were found, while no significant increases in the concentrations of these pollutants were observed. In turn, PM10 levels remained constant, with a value of 16?gm?3. In both surveys, the carcinogenic and non-carcinogenic risks derived from exposure to metals and PCDD/Fs for the population living in the vicinity of the facility were within the ranges considered as acceptable according to national and international standards. This means that RDF may be a successful choice in front of classical fossil fuels, being in accordance with the new EU environmental policies, which entail the reduction of CO2 emissions and the energetic valorization of MSW. However, further long-term environmental studies are necessary to corroborate the harmlessness of RDF, in terms of human health risks.

Burning hazardous waste in cement kilns  

SciTech Connect (OSTI)

The cement manufacturing process is one of the oldest in the world, having been in practice for over 2000 years. It is also one of the most energy intensive, with up to 65 percent of the cost of the product attributable to energy consumption. In addition to high energy demand, the process conditions include extremely high temperatures. Cement clinker forms when the correct mixture of raw materials is heated to 2650/sup 0/ F. This requires combustion temperatures exceeding 3000/sup 0/ F. under oxidizing conditions. To accomplish this, gas temperatures above 2000/sup 0/ F. occur for several seconds (typically five seconds), which is much longer than residence times in permitted hazardous waste incinerators. These conditions are extremely favorable to the destruction of organic compounds and have led to extensive investigation into the potential for burning hazardous waste in cement kilns. Cement kilns consuming hazardous wastes have been tested for air emissions under various operating conditions. The substantial body of information on the emissions and handling of hazardous wastes from these studies has demonstrated that effective destruction of wastes can be accomplished with the added benefits of energy conservation and no significant change in air emissions.

Fossil fuel furnace reactor  

DOE Patents [OSTI]

A fossil fuel furnace reactor is provided for simulating a continuous processing plant with a batch reactor. An internal reaction vessel contains a batch of shale oil, with the vessel having a relatively thin wall thickness for a heat transfer rate effective to simulate a process temperature history in the selected continuous processing plant. A heater jacket is disposed about the reactor vessel and defines a number of independent controllable temperature zones axially spaced along the reaction vessel. Each temperature zone can be energized to simulate a time-temperature history of process material through the continuous plant. A pressure vessel contains both the heater jacket and the reaction vessel at an operating pressure functionally selected to simulate the continuous processing plant. The process yield from the oil shale may be used as feedback information to software simulating operation of the continuous plant to provide operating parameters, i.e., temperature profiles, ambient atmosphere, operating pressure, material feed rates, etc., for simulation in the batch reactor.

Projection of world fossil fuels by country  

Science Journals Connector (OSTI)

Abstract Detailed projections of world fossil fuel production including unconventional sources were created by country and fuel type to estimate possible future fossil fuel production. Four critical countries (China, USA, Canada and Australia) were examined in detail with projections made on the state/province level. Ultimately Recoverable Resources (URR) for fossil fuels were estimated for three scenarios: Low=48.4 ZJ, Best Guess (BG)=75.7 ZJ, High=121.5 ZJ. The scenarios were developed using Geologic Resources Supply-Demand Model (GeRS-DeMo). The Low and Best Guess (BG) scenarios suggest that world fossil fuel production may peak before 2025 and decline rapidly thereafter. The High scenario indicates that fossil fuels may have a strong growth till 2025 followed by a plateau lasting approximately 50years before declining. All three scenarios suggest that world coal production may peak before 2025 due to peaking Chinese production and that only natural gas could have strong growth in the future. In addition, by converting the fossil fuel projections to greenhouse gas emissions, the projections were compared to IPCC scenarios which indicated that based on current estimates of URR there are insufficient fossil fuels to deliver the higher emission IPCC scenarios \\{A1Fl\\} and RCP8.5.

Hydrogen Separation Membranes for Vision 21 Fossil Fuel Plants  

SciTech Connect (OSTI)

Eltron Research and team members CoorsTek, McDermott Technology, Sued Chemie, Argonne National Laboratory, and Oak Ridge National Laboratory are developing an environmentally benign, inexpensive, and efficient method for separating hydrogen from gas mixtures produced during industrial processes, such as coal gasification. This objective is being pursued using dense membranes based in part on Eltron-patented ceramic materials with a demonstrated ability for proton and electron conduction. The technical goals are being addressed by modifying single-phase and composite membrane composition and microstructure to maximize proton and electron conductivity without loss of material stability. Ultimately, these materials must enable hydrogen separation at practical rates under ambient and high-pressure conditions, without deactivation in the presence of feedstream components such as carbon dioxide, water, and sulfur. This project was motivated by the Department of Energy (DOE) National Energy Technology Laboratory (NETL) Vision 21 initiative which seeks to economically eliminate environmental concerns associated with the use of fossil fuels. The proposed technology addresses the DOE Vision 21 initiative in two ways. First, this process offers a relatively inexpensive solution for pure hydrogen separation that can be easily incorporated into Vision 21 fossil fuel plants. Second, this process could reduce the cost of hydrogen, which is a clean burning fuel under increasing demand as supporting technologies are developed for hydrogen utilization and storage. Additional motivation for this project arises from the potential of this technology for other applications. By appropriately changing the catalysts coupled with the membrane, essentially the same system can be used to facilitate alkane dehydrogenation and coupling, aromatics processing, and hydrogen sulfide decomposition.

The European carbon balance. Part 1: fossil fuel emissions  

SciTech Connect (OSTI)

We analyzed the magnitude, the trends and the uncertainties of fossil-fuel CO2 emissions in the European Union 25 member states (hereafter EU-25), based on emission inventories from energy-use statistics. The stability of emissions during the past decade at EU-25 scale masks decreasing trends in some regions, offset by increasing trends elsewhere. In the recent 4 years, the new Eastern EU-25 member states have experienced an increase in emissions, reversing after a decade-long decreasing trend. Mediterranean and Nordic countries have also experienced a strong acceleration in emissions. In Germany, France and United Kingdom, the stability of emissions is due to the decrease in the industry sector, offset by an increase in the transportation sector. When four different inventories models are compared, we show that the between-models uncertainty is as large as 19% of the mean for EU-25, and even bigger for individual countries. Accurate accounting for fossil CO2 emissions depends on a clear understanding of system boundaries, i.e. emitting activities included in the accounting. We found that the largest source of errors between inventories is the use of distinct systems boundaries (e.g. counting or not bunker fuels, cement manufacturing, nonenergy products). Once these inconsistencies are corrected, the between-models uncertainty can be reduced down to 7% at EU-25 scale. The uncertainty of emissions at smaller spatial scales than the country scale was analyzed by comparing two emission maps based upon distinct economic and demographic activities. A number of spatial and temporal biases have been found among the two maps, indicating a significant increase in uncertainties when increasing the resolution at scales finer than 200 km. At 100km resolution, for example, the uncertainty of regional emissions is estimated to be 60 gCm2 yr1, up to 50% of the mean. The uncertainty on regional fossil-fuel CO2 fluxes to the atmosphere could be reduced by making accurate 14C measurements in atmospheric CO2, and by combining them with transport models.

Combating global warming via non-fossil fuel energy options  

Science Journals Connector (OSTI)

Non-fossil fuel energy options can help reduce or eliminate the emissions of greenhouse gases and are needed to combat climate change. Three distinct ways in which non-fossil fuel options can be used in society are examined here: the capture/production of non-fossil fuel energy sources, their conversion into appropriate energy carriers and increased efficiency throughout the life cycle. Non-fossil fuel energy sources are insufficient to avoid global warming in that they are not necessarily readily utilisable in their natural forms. Hydrogen energy systems are needed to facilitate the use of non-fossil fuels by converting them to two main classes of energy carriers: hydrogen (and hydrogen-derived fuels) and electricity. High efficiency is needed to allow the greatest benefits to be attained from energy options in terms of climate change and other factors. A case study is considered involving the production of hydrogen from non-fossil energy sources via thermochemical water decomposition. Thermochemical water decomposition provides a realistic future non-fossil fuel energy option, which can be driven by non-fossil energy sources (particularly nuclear or solar energy) and help combat global warming.

Historic patterns of CO{sub 2} emissions from fossil fuels: Implications for stabilization of emissions  

SciTech Connect (OSTI)

This paper examines the historical record of greenhouse gas emissions since 1950, reviews the prospects for emissions into the future, and projects what would be the short-term outcome if the stated targets of the FCCC were in fact achieved. The examination focuses on the most important of the greenhouse gases, CO{sub 2}. The extensive record of historic CO{sub 2} emissions is explored to ascertain if it is an adequate basis for useful extrapolation into the near future. Global carbon dioxide emissions from fossil fuel consumption have been documented. Emissions grew at 4.3% per year from 1950 until the time of the 1973 oil crisis. Another disruption in growth followed the oil price increases of 1979. Global total emissions have been increasing steadily since the 1982-1983 minimum and have grown by more than 20% since then. At present, emission Of CO{sub 2} from fossil fuel burning is dominated by a few countries: the U.S., the former Soviet Union, China, the developed countries of Europe and Japan. Only 20 countries emit 84% of emissions from all countries. However, rates of growth in many of the developed countries are now very low. In contrast, energy use has grown rapidly over the last 20 years in some of the large, developing economies. Emissions from fossil fuel consumption are now nearly 4 times those from land use change and are the primary cause of measured increases in the atmospheric concentration of CO{sub 2}. The increasing concentration of atmospheric CO{sub 2} has led to rising concern about the possibility of impending changes in the global climate system. In an effort to limit or mitigate potential negative effects of global climate change, 154 countries signed the United Nations Framework Convention on Climate Change (FCCC) in Rio de Janeiro in June, 1992. The FCCC asks all countries to conduct an inventory of their current greenhouse gas emissions setting non-binding targets.

Development of high temperature air combustion technology in pulverized fossil fuel fired boilers  

SciTech Connect (OSTI)

High temperature air combustion (HTAC) is a promising technology for energy saving, flame stability enhancement and NOx emission reduction. In a conventional HTAC system, the combustion air is highly preheated by using the recuperative or regenerative heat exchangers. However, such a preheating process is difficult to implement for pulverized fossil fuel fired boilers. In this paper, an alternative approach is proposed. In the proposed HTAC system, a special burner, named PRP burner is introduced to fulfill the preheating process. The PRP burner has a preheating chamber with one end connected with the primary air and the other end opened to the furnace. Inside the chamber, gas recirculation is effectively established such that hot flue gases in the furnace can be introduced. Combustible mixture instead of combustion air is highly preheated by the PRP burner. A series of experiments have been conducted in an industrial scale test facility, burning low volatile petroleum coke and an anthracite coal. Stable combustion was established for burning pure petroleum coke and anthracite coal, respectively. Inside the preheating chamber, the combustible mixture was rapidly heated up to a high temperature level close to that of the hot secondary air used in the conventional HTAC system. The rapid heating of the combustible mixture in the chamber facilitates pyrolysis, volatile matter release processes for the fuel particles, suppressing ignition delay and enhancing combustion stability. Moreover, compared with the results measured in the same facility but with a conventional low NOx burner, NOx concentration at the furnace exit was at the same level when petroleum coke was burnt and 50% less when anthracite was burnt. Practicability of the HTAC technology using the proposed approach was confirmed for efficiently and cleanly burning fossil fuels. 16 refs., 10 figs., 1 tab.

Causal relationship between fossil fuel consumption and economic growth in the world  

Science Journals Connector (OSTI)

Fossil fuels are major sources of energy, and have several advantages over other primary energy sources. Without extensive dependence on fossil fuels, it is questionable whether our economic prosperity can continue. This paper analyses cointegration and causality between fossil fuel consumption and economic growth in the world over the period 1971 to 2008. The estimation results indicate that fossil fuel consumption and GDP are cointegrated and there exists long-run unidirectional causality from fossil fuel consumption to GDP. This paper also investigates the nexus between non-fossil energy consumption and GDP, and shows that there is no causality between the variables. The conclusions are that reducing fossil fuel consumption may hamper economic growth, and that it is unlikely that non-fossil energy will substantially replace fossil fuels. This paper also examines causal linkages between the variables using a trivariate model, and obtains the same results as those from the bivariate model.

Liquid fossil fuel technology. Quarterly technical progress report, January-March 1980  

SciTech Connect (OSTI)

Highlights of the BETC January-March 1980 quarter were: Gasohol was tested in a cooperative effort with Southwestern Bell Telephone Co. Two fleets of 55 cars were tested using gasohol in one and gasoline in the other. No problems were encountered. The gasohol-fueled cars had less emissions, and the fuel efficiencies for both fleets were approximately the same. An in situ combustion has been successfully started in a heavy oil deposit in Kansas. After some difficulties in starting the burn, it is now operating satisfactorily and producing oil. Cooperation between DOE and the Venezuelan oil industry was explored in a meeting at BETC that emphasized efforts to produce heavy oil. Cooperation through the International Energy Agency is expected to result in sharing of technology on enhanced oil recovery. Petroleum product surveys are produced cooperatively by DOE and the American Petroleum Institute. They give the properties of the products currently being marketed in the US. During the quarter, surveys on Motor Gasolines, Summer 1979 and Diesel Fuel Oils, 1979 were published. They are used to trace changes in characteristics and also to set specifications. The size of colloids, micelles, and emulsions in petroleum and associated liquids can be a factor in the design of improved recovery processes. The use of small angle x-ray scattering has been facilitated by a new method of calculation. The development of the Liquid Fossil Fuel Cycle has been facilitated by a workshop and further discussions resulting in a new statement Planning Framework for Liquid Fossil Fuel Cycle, March 1, 1980. This has now been used to prepare a computer-processible form to use in a critical path study of the BETC program.

Large historical changes of fossil-fuel black carbon aerosols  

SciTech Connect (OSTI)

Anthropogenic emissions of fine black carbon (BC) particles, the principal light-absorbing atmospheric aerosol, have varied during the past century in response to changes of fossil-fuel utilization, technology developments, and emission controls. We estimate historical trends of fossil-fuel BC emissions in six regions that represent about two-thirds of present day emissions and extrapolate these to global emissions from 1875 onward. Qualitative features in these trends show rapid increase in the latter part of the 1800s, the leveling off in the first half of the 1900s, and the re-acceleration in the past 50 years as China and India developed. We find that historical changes of fuel utilization have caused large temporal change in aerosol absorption, and thus substantial change of aerosol single scatter albedo in some regions, which suggests that BC may have contributed to global temperature changes in the past century. This implies that the BC history needs to be represented realistically in climate change assessments.

Control of SO{sub 2} and NOx emissions from fossil fuel-fired power plants: Research and practice of TPRI  

SciTech Connect (OSTI)

The generation of electric power in China has been dominated by coal for many years. By the end of 1990, total installed generating capacity reached 135 GW, of which fossil fuel-fired plants accounted for 74 percent. The total electricity generated reached 615 TWh, with fossil fuels accounting for 80.5 percent. About 276 million tons of raw coal are consumed in these fossil fuel-burning units per year, accounting for about 25 percent of the total output of the country. According to the government, by the year 2000, the total installed capacity of Chinese power systems should be at least 240 GW, of which fossil fuels will account for about 77 percent. The coal required for power generation will increase to about 530 million tons per year, accounting for about 38 percent of the total coal output. So, it is obvious that coal consumed in coal-fired power plants occupies a very important place in the national fuel balance. The current environmental protection standards, which are based on ground-level concentrations of pollutants, do not effectively lead to the control of pollution emission concentrations or total SO{sub 2} emissions. Due to the practical limitations of the Chinese economy, there is a limited capability to introduce advanced sulfur emission control technologies. Thus, except for the two 360 MW units imported from Japan for the Luohuang Power Plant in Shichuan province, all the other fossil fuel-fired units have not yet adopted any kind of SO{sub 2} removal measures. The Luohuang units are equipped with Mitsubishi limestone flue gas desulfurization systems. Because of the lack of effective pollution control technologies, large areas of the country have been seriously polluted by SO{sub 2}, and some of them even by acid rain.

Classification of fossil fuels according to structural-chemical characteristics  

SciTech Connect (OSTI)

On the basis of a set of linear equations that relate the amount of major elements n{sub E} (E = C, H, O, N, S) in the organic matter of fossil fuels to structural characteristics, such as the number of cycles R, the number of atoms n{sub E}, the number of mutual chemical bonds, the degree of unsaturation of the structure {delta}, and the extent of its reduction B, a structural-chemical classification of fossil coals that is closely related to the parameters of the industrial-genetic classification (GOST 25543-88) is proposed. Structural-chemical classification diagrams are constructed for power-generating coals of Russia; coking coals; and coals designed for nonfuel purposes including the manufacture of adsorbents, synthetic liquid fuel, ion exchangers, thermal graphite, and carbon-graphite materials.

Krakow Clean Fossil Fuels and Energy Efficiency Program  

SciTech Connect (OSTI)

The Support for Eastern European Democracy (SEED) Act of 1989 directed the US Department of Energy (DOE) to undertake an equipment assessment project aimed at developing the capability within Poland to manufacture or modify industrial-scale combustion equipment to utilize fossil fuels cleanly. The project is being conducted in three phases. In Phase I, testing and analytical activities will establish the current level of emissions from existing equipment and operating practices, and will provide estimates of the costs and emission reductions of various options. Phase II consists of a series of public meetings in both Poland and the United States to present the results of Phase I activities. In Phase III, DOE will issue a solicitation for Polish/US joint ventures to perform commercial feasibility studies for the use of US technology in one or more of the areas under consideration. This report provides interim results from Phase 1.

Synergistic energy conversion processes using nuclear energy and fossil fuels  

Science Journals Connector (OSTI)

This paper reviews the methods of producing energy carriers, such as electricity, hydrocarbons and hydrogen, by utilising both nuclear energy and fossil fuels synergistically. There are many possibilities for new, innovative, synergistic processes, which combine chemical and nuclear systems for efficient, clean and economical production of energy carriers. Besides the individual processes by each form of energy to produce the energy carriers, the synergistic processes which use two primary energies to produce the energy carriers will become important with the features of resource saving, CO2 emission reduction and economic production, due to the higher conversion efficiency and low cost of nuclear heat. The synergistic processes will be indispensable to the 21st century, when efficient best-mixed supplies of available primary energies are crucial.

ADVANCED HYDROGEN TRANSPORT MEMBRANES FOR VISION 21 FOSSIL FUEL PLANTS  

SciTech Connect (OSTI)

Eltron Research Inc., and team members, are developing an environmentally benign, inexpensive, and efficient method for separating hydrogen from gas mixtures produced during industrial processes, such as coal gasification. This project was motivated by the National Energy Technology Laboratory (NETL) Vision 21 initiative which seeks to economically eliminate environmental concerns associated with the use of fossil fuels. This objective is being pursued using dense membranes based in part on Eltron-patented ceramic materials with a demonstrated ability for proton and electron conduction. The technical goals are being addressed by modifying single-phase and composite membrane composition and microstructure to maximize proton and electron conductivity without loss of material stability. Ultimately, these materials must enable hydrogen separation at practical rates under ambient and high-pressure conditions, without deactivation in the presence of feedstream components such as carbon dioxide, water, and sulfur. During this quarter, ceramic, cermet (ceramic/metal), and thin film membranes were prepared, characterized, and evaluated for H{sub 2} transport. For selected ceramic membrane compositions an optimum range for transition metal doping was identified, and it was determined that highest proton conductivity occurred for two-phase ceramic materials. Furthermore, a relationship between transition metal dopant atomic number and conductivity was observed. Ambipolar conductivities of {approx}6 x 10{sup -3} S/cm were achieved for these materials, and {approx} 1-mm thick membranes generated H{sub 2} transport rates as high as 0.3 mL/min/cm{sup 2}. Cermet membranes during this quarter were found to have a maximum conductivity of 3 x 10{sup -3} S/cm, which occurred at a metal phase contact of 36 vol.%. Homogeneous dense thin films were successfully prepared by tape casting and spin coating; however, there remains an unacceptably high difference in shrinkage rates between the film and support, which led to membrane instability. Further improvements in high pressure membrane seals also were achieved during this quarter, and a maximum pressure of 100 psig was attained. CoorsTek optimized many of the processing variables relevant to manufacturing scale production of ceramic H{sub 2} transport membranes, and SCI used their expertise to deposit a range of catalysts compositions onto ceramic membrane surfaces. Finally, MTI compiled relevant information regarding Vision 21 fossil fuel plant operation parameters, which will be used as a starting point for assessing the economics of incorporating a H{sub 2} separation unit.

Alternative Fuel for Portland Cement Processing  

SciTech Connect (OSTI)

The production of cement involves a combination of numerous raw materials, strictly monitored system processes, and temperatures on the order of 1500 °C. Immense quantities of fuel are required for the production of cement. Traditionally, energy from fossil fuels was solely relied upon for the production of cement. The overarching project objective is to evaluate the use of alternative fuels to lessen the dependence on non-renewable resources to produce portland cement. The key objective of using alternative fuels is to continue to produce high-quality cement while decreasing the use of non-renewable fuels and minimizing the impact on the environment. Burn characteristics and thermodynamic parameters were evaluated with a laboratory burn simulator under conditions that mimic those in the preheater where the fuels are brought into a cement plant. A drop-tube furnace and visualization method were developed that show potential for evaluating time- and space-resolved temperature distributions for fuel solid particles and liquid droplets undergoing combustion in various combustion atmospheres. Downdraft gasification has been explored as a means to extract chemical energy from poultry litter while limiting the throughput of potentially deleterious components with regards to use in firing a cement kiln. Results have shown that the clinkering is temperature independent, at least within the controllable temperature range. Limestone also had only a slight effect on the fusion when used to coat the pellets. However, limestone addition did display some promise in regards to chlorine capture, as ash analyses showed chlorine concentrations of more than four times greater in the limestone infused ash as compared to raw poultry litter. A reliable and convenient sampling procedure was developed to estimate the combustion quality of broiler litter that is the best compromise between convenience and reliability by means of statistical analysis. Multi-day trial burns were conducted at a full-scale cement plant with alternative fuels to examine their compatibility with the cement production process. Construction and demolition waste, woodchips, and soybean seeds were used as alternative fuels at a full-scale cement production facility. These fuels were co-fired with coal and waste plastics. The alternative fuels used in this trial accounted for 5 to 16 % of the total energy consumed during these burns. The overall performance of the portland cement produced during the various trial burns performed for practical purposes very similar to the cement produced during the control burn. The cement plant was successful in implementing alternative fuels to produce a consistent, high-quality product that increased cement performance while reducing the environmental footprint of the plant. The utilization of construction and demolition waste, woodchips and soybean seeds proved to be viable replacements for traditional fuels. The future use of these fuels depends on local availability, associated costs, and compatibility with a facility??s production process.

INNOVATIVE FOSSIL FUEL FIRED VITRIFICATION TECHNOLOGY FOR SOIL REMEDIATION  

SciTech Connect (OSTI)

This Summary Report summarizes the progress of Phases 3, 3A and 4 of a waste technology Demonstration Project sponsored under a DOE Environmental Management Research and Development Program and administered by the U.S. Department of Energy National Energy Technology Laboratory-Morgantown (DOE-NETL) for an ''Innovative Fossil Fuel Fired Vitrification Technology for Soil Remediation''. The Summary Reports for Phases 1 and 2 of the Program were previously submitted to DOE. The total scope of Phase 3 was to have included the design, construction and demonstration of Vortec's integrated waste pretreatment and vitrification process for the treatment of low level waste (LLW), TSCA/LLW and mixed low-level waste (MLLW). Due to funding limitations and delays in the project resulting from a law suit filed by an environmental activist and the extended time for DOE to complete an Environmental Assessment for the project, the scope of the project was reduced to completing the design, construction and testing of the front end of the process which consists of the Material Handling and Waste Conditioning (MH/C) Subsystem of the vitrification plant. Activities completed under Phases 3A and 4 addressed completion of the engineering, design and documentation of the Material Handling and Conditioning System such that final procurement of the remaining process assemblies can be completed and construction of a Limited Demonstration Project be initiated in the event DOE elects to proceed with the construction and demonstration testing of the MH/C Subsystem.

Eltron Research Inc. and team members CoorsTek, Sued Chemie, Argonne National Laboratory, and NORAM are developing an environmentally benign, inexpensive, and efficient method for separating hydrogen from gas mixtures produced during industrial processes, such as coal gasification. This project was motivated by the National Energy Technology Laboratory (NETL) Vision 21 initiative, which seeks to economically eliminate environmental concerns associated with the use of fossil fuels. Currently, this project is focusing on four basic categories of dense membranes: (1) mixed conducting ceramic/ceramic composites, (2) mixed conducting ceramic/metal (cermet) composites, (3) cermets with hydrogen permeable metals, and (4) layered composites containing hydrogen permeable alloys. Ultimately, these materials must enable hydrogen separation at practical rates under ambient and high-pressure conditions, without deactivation in the presence of feedstream components such as carbon dioxide, water, and sulfur. During this final quarter of the no cost extension several planar membranes of a cermet composition referred to as EC101 containing a high permeability metal and a ceramic phase were prepared and permeability testing was performed.

Monthly, global emissions of carbon dioxide from fossil fuel consumption  

SciTech Connect (OSTI)

This paper examines available data, develops a strategy and presents a monthly, global time series of fossil-fuel carbon dioxide emissions for the years 1950 2006. This monthly time series was constructed from detailed study of monthly data from the 21 countries that account for approximately 80% of global total emissions. These data were then used in a Monte Carlo approach to proxy for all remaining countries. The proportional-proxy methodology estimates by fuel group the fraction of annual emissions emitted in each country and month. Emissions from solid, liquid and gas fuels are explicitly modelled by the proportional-proxy method. The primary conclusion from this study is the global monthly time series is statistically significantly different from a uniform distribution throughout the year. Uncertainty analysis of the data presented show that the proportional-proxy method used faithfully reproduces monthly patterns in the data and the global monthly pattern of emissions is relatively insensitive to the exact proxy assignments used. The data and results presented here should lead to a better understanding of global and regional carbon cycles, especially when the mass data are combined with the stable carbon isotope data in atmospheric transport models.

SciTech Connect (OSTI)

Eltron Research Inc., and team members, are developing an environmentally benign, inexpensive, and efficient method for separating hydrogen from gas mixtures produced during industrial processes, such as coal gasification. This project was motivated by the National Energy Technology Laboratory (NETL) Vision 21 initiative which seeks to economically eliminate environmental concerns associated with the use of fossil fuels. This objective is being pursued using dense membranes based in part on Eltron-patented ceramic materials with a demonstrated ability for proton and electron conduction. The technical goals are being addressed by modifying single-phase and composite membrane composition and microstructure to maximize proton and electron conductivity without loss of material stability. Ultimately, these materials must enable hydrogen separation at practical rates under ambient and high-pressure conditions, without deactivation in the presence of feedstream components such as carbon dioxide, water, and sulfur. During this quarter, it was demonstrated that increasing the transition metal loading in a model perovskite composition resulted in an increase in hydrogen flux. Improved flux corresponded to the emergence of additional phases in the ceramic membrane, and highest flux was achieved for a composite consisting of pseudo-cubic and rhombohedral perovskite phases. A 0.9-mm thick membrane of this material generated a hydrogen flux in excess of 0.1 mL/min/cm{sup 2}, which was approximately 35 times greater than analogs with lower transition metal levels. The dopant level and crystal structure also correlated with membrane density and coefficient of thermal expansion, but did not appear to affect grain size or shape. Additionally, preliminary ceramic-metal (cermet) composite membranes demonstrated a 10-fold increase in flux relative to analogous membranes composed of only the ceramic component. The hydrogen flux for these cermet samples corresponded to a conductivity of {approx} 10{sup -3} S/cm, which was consistent with the predicted proton conductivity of the ceramic phase. Increasing the sweep gas flow rate in test reactors was found to significantly increase hydrogen flux, as well as apparent material conductivity for all samples tested. Adding humidity to the feed gas stream produced a small increase in hydrogen flux. However, the catalyst on ceramic membrane surfaces did not affect flux, which suggested that the process was membrane-diffusion limited. Representative samples and fabrication processes were evaluated on the basis of manufacturing practicality. it was determined that optimum membrane densification occurs over a very narrow temperature range for the subject ceramics. Additionally, calcination temperatures currently employed result in powders that are difficult mill and screen. These issues must be addressed to improve large-scale fabricability.

Ultimately, these materials must enable hydrogen separation at practical rates under ambient and high-pressure conditions, without deactivation in the presence of feedstream components such as carbon dioxide, water, and sulfur. During this quarter, new cermet compositions were tested that demonstrated similar performance to previous materials. A 0.5-mm thick membrane achieved at H{sub 2} transport rate of 0.2 mL/min/cm{sup 2} at 950 C, which corresponded to an ambipolar conductivity of 3 x 10{sup -3} S/cm. Although these results were equivalent to those for other cermet compositions, this new composition might be useful if it demonstrates improved chemical or mechanical stability. Ceramic/ceramic composite membranes also were fabricated and tested; however, some reaction did occur between the proton- and electron-conducting phases, which likely compromised conductivity. This sample only achieved a H{sub 2} transport rate of {approx} 0.006 mL/min/cm{sup 2} and an ambipolar conductivity of {approx}4 x 10{sup -4} S/cm. Chemical stability tests were continued, and candidate ceramic membranes were found to react slightly with carbon monoxide under extreme testing conditions. A cermet compositions did not show any reaction with carbon monoxide, but a thick layer of carbon formed on the membrane surface. The most significant technical accomplishment this quarter was a new high-pressure seal composition. This material maintained a pressure differential across the membrane of {approx} 280 psi at 800 C, and is still in operation.

Ultimately, these materials must enable hydrogen separation at practical rates under ambient and high-pressure conditions, without deactivation in the presence of feedstream components such as carbon dioxide, water, and sulfur. During this quarter, mixed proton/electron conductivity and hydrogen transport was measured as a function of metal phase content for a range of ceramic/metal (cermet) compositions. It was found that optimum performance occurred at 44 wt.% metal content for all compositions tested. Although each cermet appeared to have a continuous metal phase, it is believed that hydrogen transport increased with increasing metal content partially due to beneficial surface catalyst characteristics resulting from the metal phase. Beyond 44 wt.% there was a reduction in hydrogen transport most likely due to dilution of the proton conducting ceramic phase. Hydrogen separation rates for 1-mm thick cermet membranes were in excess of 0.1 mL/min/cm{sup 2}, which corresponded to ambipolar conductivities between 1 x 10{sup -3} and 8 x 10{sup -3} S/cm. Similar results were obtained for multiphase ceramic membranes comprised of a proton-conducting perovskite and electron conducting metal oxide. These multi-phase ceramic membranes showed only a slight improvement in hydrogen transport upon addition of a metal phase. The highest hydrogen separation rates observed this quarter were for a cermet membrane containing a hydrogen transport metal. A 1-mm thick membrane of this material achieved a hydrogen separation rate of 0.3 mL/min/cm{sup 2} at only 700 C, which increased to 0.6 mL/min/cm{sup 2} at 950 C.

ADVANCED HYDROGEN TRANSPORT MEMBRANES FOR VISION 21 FOSSIL FUEL PLANTS  

SciTech Connect (OSTI)

Eltron Research Inc., and team members CoorsTek, Sued Chemie, and Argonne National Laboratory are developing an environmentally benign, inexpensive, and efficient method for separating hydrogen from gas mixtures produced during industrial processes, such as coal gasification. This project was motivated by the National Energy Technology Laboratory (NETL) Vision 21 initiative which seeks to economically eliminate environmental concerns associated with the use of fossil fuels. This objective is being pursued using dense membranes based in part on Eltron-patented ceramic materials with a demonstrated ability for proton and electron conduction. The technical goals are being addressed by modifying composite membrane composition and microstructure to maximize hydrogen permeation without loss of material stability. Ultimately, these materials must enable hydrogen separation at practical rates under ambient and high-pressure conditions, without deactivation in the presence of feedstream components such as carbon dioxide, water, and sulfur. During this quarter, a composite metal membrane based on an inexpensive hydrogen permeable metal achieved permeation rates in excess of 25 mL/min/cm{sup 2}. Preliminary attempts to incorporate this metal into a cermet were successful, and a thick cermet membrane (0.83 mm) with 40 vol.% metal phase achieved a permeation rate of nearly 0.4 mL/min/cm{sup 2}. Increasing the metal phase content and decreasing membrane thickness should significantly increase permeation, while maintaining the benefits derived from cermets. Two-phase ceramic/ceramic composite membranes had low hydrogen permeability, likely due to interdiffusion of constituents between the phases. However, these materials did demonstrate high resistance to corrosion, and might be good candidates for other composite membranes. Temperature-programmed reduction measurements indicated that model cermet materials absorbed 2.5 times as much hydrogen than the pure ceramic analogs. This characteristic, in addition to higher electron conductivity, likely explains the relatively high permeation for these cermets. Incorporation of catalysts with ceramics and cermets increased hydrogen uptake by 800 to more than 900%. Finally, new high-pressure seals were developed for cermet membranes that maintained a pressure differential of 250 psi. This result indicated that the approach for high-pressure seal development could be adapted for a range of compositions. Other items discussed in this report include mechanical testing, new proton conducting ceramics, supported thin films, and alkane to olefin conversion.

Broader source: Energy.gov (indexed) [DOE]

renewable sources of power. Demand for fossil fuels surely will overrun supply sooner or later, renewable sources of power. Demand for fossil fuels surely will overrun supply sooner or later, as indeed it already has in the casc of United States domestic oil drilling. Recognition also is growing that our air and land can no longer absorb unlimited quantities of waste from fossil fuel extraction and combustion. As that day draws nearer, policymakers will have no realistic alternative but to turn to sources of power that today make up a viable but small part of America's energy picture. And they will be forced to embrace energy efficiencies - those that are within our reach today, and those that will be developed tomorrow. Precisely when they come lo grips with that reality - this year, 10 years from now, or 20 years from now - will determine bow smooth the transition will be for consumers and industry alike.

Fossil fuel producing economies have greater potential for industrial interfuel substitution  

Science Journals Connector (OSTI)

Abstract This study analyzes industrial interfuel substitution in an international context using a large unbalanced panel dataset of 63 countries. We find that compared to other countries fossil fuel producing economies have higher short-term interfuel substitution elasticities. This difference increases further in the long run as fossil fuel producing countries have a considerably longer adjustment of their fuel-using capital stock. These results imply lower economic cost for policies aimed at climate abatement and more efficient utilization of energy resources in energy-intensive economies.

Impacts of Wind and Solar on Fossil-Fueled Generators: Preprint  

SciTech Connect (OSTI)

High penetrations of wind and solar power will impact the operations of the remaining generators on the power system. Regional integration studies have shown that wind and solar may cause fossil-fueled generators to cycle on and off and ramp down to part load more frequently and potentially more rapidly. Increased cycling, deeper load following, and rapid ramping may result in wear-and-tear impacts on fossil-fueled generators that lead to increased capital and maintenance costs, increased equivalent forced outage rates, and degraded performance over time. Heat rates and emissions from fossil-fueled generators may be higher during cycling and ramping than during steady-state operation. Many wind and solar integration studies have not taken these increased cost and emissions impacts into account because data have not been available. This analysis considers the cost and emissions impacts of cycling and ramping of fossil-fueled generation to refine assessments of wind and solar impacts on the power system.

High resolution fossil fuel combustion CO2 emission fluxes for the United States  

SciTech Connect (OSTI)

Quantification of fossil fuel CO{sub 2} emissions at fine space and time resolution is emerging as a critical need in carbon cycle and climate change research. As atmospheric CO{sub 2} measurements expand with the advent of a dedicated remote sensing platform and denser in situ measurements, the ability to close the carbon budget at spatial scales of {approx}100 km{sup 2} and daily time scales requires fossil fuel CO{sub 2} inventories at commensurate resolution. Additionally, the growing interest in U.S. climate change policy measures are best served by emissions that are tied to the driving processes in space and time. Here we introduce a high resolution data product (the 'Vulcan' inventory: www.purdue.edu/eas/carbon/vulcan/) that has quantified fossil fuel CO{sub 2} emissions for the contiguous U.S. at spatial scales less than 100 km{sup 2} and temporal scales as small as hours. This data product, completed for the year 2002, includes detail on combustion technology and 48 fuel types through all sectors of the U.S. economy. The Vulcan inventory is built from the decades of local/regional air pollution monitoring and complements these data with census, traffic, and digital road data sets. The Vulcan inventory shows excellent agreement with national-level Department of Energy inventories, despite the different approach taken by the DOE to quantify U.S. fossil fuel CO{sub 2} emissions. Comparison to the global 1{sup o} x 1{sup o} fossil fuel CO{sub 2} inventory, used widely by the carbon cycle and climate change community prior to the construction of the Vulcan inventory, highlights the space/time biases inherent in the population-based approach.

Spatial Relationships of Sector-Specific Fossil-fuel CO2 Emissions in the United States  

SciTech Connect (OSTI)

Quantification of the spatial distribution of sector-specific fossil fuel CO2 emissions provides strategic information to public and private decision-makers on climate change mitigation options and can provide critical constraints to carbon budget studies being performed at the national to urban scales. This study analyzes the spatial distribution and spatial drivers of total and sectoral fossil fuel CO2 emissions at the state and county levels in the United States. The spatial patterns of absolute versus per capita fossil fuel CO2 emissions differ substantially and these differences are sector-specific. Area-based sources such as those in the residential and commercial sectors are driven by a combination of population and surface temperature with per capita emissions largest in the northern latitudes and continental interior. Emission sources associated with large individual manufacturing or electricity producing facilities are heterogeneously distributed in both absolute and per capita metrics. The relationship between surface temperature and sectoral emissions suggests that the increased electricity consumption due to space cooling requirements under a warmer climate may outweigh the savings generated by lessened space heating. Spatial cluster analysis of fossil fuel CO2 emissions confirms that counties with high (low) CO2 emissions tend to be clustered close to other counties with high (low) CO2 emissions and some of the spatial clustering extends to multi-state spatial domains. This is particularly true for the residential and transportation sectors, suggesting that emissions mitigation policy might best be approached from the regional or multi-state perspective. Our findings underscore the potential for geographically focused, sector-specific emissions mitigation strategies and the importance of accurate spatial distribution of emitting sources when combined with atmospheric monitoring via aircraft, satellite and in situ measurements.

Assessment of a multi-stage underwater vehicle concept using a fossil-fuel Stirling engine  

SciTech Connect (OSTI)

The Stirling Engine because of its inherent closed-cycle operation can be readily modified to work in an airless environment even if the primary source of energy is a fossil fuel. Thus, Stirling engines are well suited for use in the underwater environment and have been operated successfully in manned military submarines since the early 1980s. In recent years fossil fueled Stirling systems have been also proposed for use in small unmanned underwater vehicles (UUVs). However, in this case the need to carry an onboard oxygen supply in a very confined space has presented a number of design difficulties. These are identified in the paper. However, if the oxidant supply to the engine is provided by the membrane extraction of dissolved oxygen from seawater and/or disposable fuel/oxidant pods are used then the UUV Stirling system becomes more attractive. If this latter concept is extended to include multi-stage vehicles then it can be shown that fossil fueled Stirlings could also be put to effective use in long range-long endurance underwater vehicular operations.

A fast method for updating global fossil fuel carbon dioxide emissions  

Science Journals Connector (OSTI)

We provide a fast and efficient method for calculating global annual mean carbon dioxide emissions from the combustion of fossil fuels by combining data from an established data set with BP annual statistics. Using this method it is possible to retrieve an updated estimate of global CO2 emissions six months after the actual emissions occurred. Using this data set we find that atmospheric carbon dioxide emissions have increased by over 40% from 1990 to 2008 with an annual average increase of 3.7% over the five-year period 2003?2007. In 2008 the growth rate in the fossil fuel carbon dioxide emissions was smaller than in the preceding five years, but it was still over 2%. Global mean carbon dioxide emissions in 2008 were 8.8?GtC? yr?1. For the latter part of the last century emissions of carbon dioxide have been greater from oil than from coal. However during the last few years this situation has changed. The recent strong increase in fossil fuel CO2 emissions is mainly driven by an increase in emissions from coal, whereas emissions from oil and gas to a large degree follow the trend from the 1990s.

Presence of estrogenic activity from emission of fossil fuel combustion as detected by a recombinant yeast bioassay  

Science Journals Connector (OSTI)

Estrogenic activities of emission samples generated by fossil fuel combustion were investigated with human estrogen receptor (ER) recombinant yeast bioassay. The results showed that there were weak but clear estrogenic activities in combustion emissions of fossil fuels including coal, petroleum, and diesel. The estrogenic relative potency (RP) of fossil fuel combustion was the highest in petroleum-fired car, followed by coal-fired stove, diesel-fired agrimotor, coal-fired electric power station. On the other hand, the estrogenic relative inductive efficiency (RIE) was the highest in coal-fired stove and coal-fired electric power station, followed by petroleum-fired car and diesel-fired agrimotor. The estrogenic activities in the sub-fractions from chromatographic separation of emitted materials were also determined. The results indicated that different chemical fractions in these complex systems have different estrogenic potencies. The GC/MS analysis of the emission showed that there were many aromatic carbonyls, big molecular alcohol, \\{PAHs\\} and derivatives, and substituted phenolic compounds and derivatives which have been reported as environmental estrogens. The existence of estrogenic substances in fossil fuel combustion demands further investigation of their potential adverse effects on human and on the ecosystem. The magnitude of pollution due to global usage of fossil fuels makes it imperative to understand the issue of fossil fuel-derived endocrine activities and the associated health risks, particularly the aggregated risks stemmed from exposure to toxicants of multiple sources.

Integrated capture of fossil fuel gas pollutants including CO.sub.2 with energy recovery  

DOE Patents [OSTI]

A method of reducing pollutants exhausted into the atmosphere from the combustion of fossil fuels. The disclosed process removes nitrogen from air for combustion, separates the solid combustion products from the gases and vapors and can capture the entire vapor/gas stream for sequestration leaving near-zero emissions. The invention produces up to three captured material streams. The first stream is contaminant-laden water containing SO.sub.x, residual NO.sub.x particulates and particulate-bound Hg and other trace contaminants. The second stream can be a low-volume flue gas stream containing N.sub.2 and O.sub.2 if CO2 purification is needed. The final product stream is a mixture comprising predominantly CO.sub.2 with smaller amounts of H.sub.2O, Ar, N.sub.2, O.sub.2, SO.sub.X, NO.sub.X, Hg, and other trace gases.

Modelling and forecasting fossil fuels, CO2 and electricity prices and their volatilities  

Science Journals Connector (OSTI)

In the current uncertain context that affects both the world economy and the energy sector, with the rapid increase in the prices of oil and gas and the very unstable political situation that affects some of the largest raw materials producers, there is a need for developing efficient and powerful quantitative tools that allow to model and forecast fossil fuel prices, CO2 emission allowances prices as well as electricity prices. This will improve decision making for all the agents involved in energy issues. Although there are papers focused on modelling fossil fuel prices, CO2 prices and electricity prices, the literature is scarce on attempts to consider all of them together. This paper focuses on both building a multivariate model for the aforementioned prices and comparing its results with those of univariate ones, in terms of prediction accuracy (univariate and multivariate models are compared for a large span of days, all in the first 4 months in 2011) as well as extracting common features in the volatilities of the prices of all these relevant magnitudes. The common features in volatility are extracted by means of a conditionally heteroskedastic dynamic factor model which allows to solve the curse of dimensionality problem that commonly arises when estimating multivariate GARCH models. Additionally, the common volatility factors obtained are useful for improving the forecasting intervals and have a nice economical interpretation. Besides, the results obtained and methodology proposed can be useful as a starting point for risk management or portfolio optimization under uncertainty in the current context of energy markets.

Quantification of fossil fuel CO2 emissions at the building/street scale for a large US city  

SciTech Connect (OSTI)

In order to advance the scientific understanding of carbon exchange with the land surface, build an effective carbon monitoring system and contribute to quantitatively-based U.S. climate change policy interests, fine spatial and temporal quantification of fossil fuel CO2 emissions, the primary greenhouse gas, is essential. Called the Hestia Project, this research effort is the first to use bottom-up methods to quantify all fossil fuel CO2 emissions down to the scale of individual buildings, road segments, and industrial/electricity production facilities on an hourly basis for an entire urban landscape. a large city (Indianapolis, Indiana USA). Here, we describe the methods used to quantify the on-site fossil fuel CO2 emissions across the city of Indianapolis, Indiana. This effort combines a series of datasets and simulation tools such as a building energy simulation model, traffic data, power production reporting and local air pollution reporting. The system is general enough to be applied to any large U.S. city and holds tremendous potential as a key component of a carbon monitoring system in addition to enabling efficient greenhouse gas mitigation and planning. We compare our estimate of fossil fuel emissions from natural gas to consumption data provided by the local gas utility. At the zip code level, we achieve a bias adjusted pearson r correlation value of 0.92 (p<0.001).

High Efficiency Direct Carbon and Hydrogen Fuel Cells for Fossil Fuel Power Generation  

SciTech Connect (OSTI)

Hydrogen he1 cells have been under development for a number of years and are now nearing commercial applications. Direct carbon fuel cells, heretofore, have not reached practical stages of development because of problems in fuel reactivity and cell configuration. The carbon/air fuel cell reaction (C + O{sub 2} = CO{sub 2}) has the advantage of having a nearly zero entropy change. This allows a theoretical efficiency of 100 % at 700-800 C. The activities of the C fuel and CO{sub 2} product do not change during consumption of the fuel. Consequently, the EMF is invariant; this raises the possibility of 100% fuel utilization in a single pass. (In contrast, the high-temperature hydrogen fuel cell has a theoretical efficiency of and changes in fuel activity limit practical utilizations to 75-85%.) A direct carbon fuel cell is currently being developed that utilizes reactive carbon particulates wetted by a molten carbonate electrolyte. Pure COZ is evolved at the anode and oxygen from air is consumed at the cathode. Electrochemical data is reported here for the carbon/air cell utilizing carbons derived from he1 oil pyrolysis, purified coal, purified bio-char and petroleum coke. At 800 O C, a voltage efficiency of 80% was measured at power densities of 0.5-1 kW/m2. Carbon and hydrogen fuels may be produced simultaneously at lugh efficiency from: (1) natural gas, by thermal decomposition, (2) petroleum, by coking or pyrolysis of distillates, (3) coal, by sequential hydrogasification to methane and thermal pyrolysis of the methane, with recycle of the hydrogen, and (4) biomass, similarly by sequential hydrogenation and thermal pyrolysis. Fuel production data may be combined with direct C and H2 fuel cell operating data for power cycle estimates. Thermal to electric efficiencies indicate 80% HHV [85% LHV] for petroleum, 75.5% HHV [83.4% LHV] for natural gas and 68.3% HHV [70.8% LHV] for lignite coal. Possible benefits of integrated carbon and hydrogen fuel cell power generation cycles are: (1) increased efficiency by a factor of up to 2 over many conventional fossil fuel steam plants, (2) reduced power generation cost, especially for increasing fossil fuel cost, (3) reduced CO2 emission per kWh, and (4) direct sequestration or reuse (e.g., in enhanced oil or NG recovery) of the CO{sub 2} product.

Waste biomass from production process co-firing with coal in a steam boiler to reduce fossil fuel consumption: A case study  

Science Journals Connector (OSTI)

Abstract Waste biomass is always generated during the production process in industries. The ordinary way to get rid of the waste biomass is to send them to landfill or burn it in the open field. The waste may potentially be used for co-firing with coal to save fossil fuel consumption and also reduce net carbon emissions. In this case study, the bio-waste from a Nicotiana Tabacum (NT) pre-treatment plant is used as the biomass to co-fire with coal. The samples of NT wastes were analysed. It was found that the wastes were of the relatively high energy content which were suitable for co-firing with coal. To investigate the potential and benefits for adding NT wastes to a Fluidised Bed Combustion (FBC) boiler in the plant, detailed modelling and simulation are carried out using the European Coal Liquefaction Process Simulation and Evaluation (ECLIPSE) process simulation package. The feedstock blending ratios of NT waste to coal studied in this work are varied from 0% to 30%. The results show that the addition of NT wastes may decrease the emissions of CO2 and \\{SOx\\} without reducing the boiler performance.

Separation of particulate from flue gas of fossil fuel combustion and gasification  

DOE Patents [OSTI]

The gas from combustion or gasification of fossil fuel contains flyash and other particulate. The flyash is separated from the gas in a plurality of standleg moving granular-bed filter modules. Each module includes a dipleg through which the bed media flows into the standleg. The bed media forms a first filter bed having an upper mass having a first frusto-conical surface in a frusto-conical member at the entrance to the standleg and a lower mass having a second frusto-conical surface of substantially greater area than the first surface after it passes through the standleg. A second filter media bed may be formed above the first filter media bed. The gas is fed tangentially into the module above the first surface. The flyash is captured on the first frusto-conical surface and within the bed mass. The processed gas flows out through the second frusto-conical surface and then through the second filter bed, if present. The bed media is cleaned of the captured flyash and recirculated to the moving granular bed filter. Alternatively, the bed media may be composed of the ash from the combustion which is pelletized to form agglomerates. The ash flows through the bed only once; it is not recycled.

A technical and environmental comparison between hydrogen and some fossil fuels  

Science Journals Connector (OSTI)

Abstract The exploitation of some fossil fuels such as oil, intended as gasoline or diesel fuel, natural gas and coal, currently satisfy the majority of the growing world energy demand, but they are destined to run out relatively quickly. Beyond this point, their combustion products are the main cause of some global problems such as the greenhouse effect, the hole in the ozone layer, acid rains and generalized environment pollution, so their impact is extremely harmful. Therefore, it is clear that a solution to the energy problem can be obtained only through the use of renewable sources and by means of the exploitation of new low-polluting fuels. In this scenario an important role might be played by hydrogen, which is able to define a new energy system that is more sustainable and cleaner than current systems. For the comparison of the different fuels investigated in this paper, a methodology, which defines appropriate technical and environmental quality indexes, has been developed. These indexes are connected to the pollution produced by combustion reactions and to their intrinsic characteristics of flammability and expansiveness linked to the use of the considered fuels. An appropriate combination of these indexes, in the specific sector of utilization, allows to evaluate a global environmental index for the investigated fuels, highlighting that hydrogen reaches the highest score. In the final part of the paper, a new hydrogen energy economy that would lead to solving the serious environmental problems that damages all the ecosystems of the planet earth, is presented.

Liquid fossil fuel technology. Quarterly technical progress report, October-December 1981  

SciTech Connect (OSTI)

Progress reports are presented for the following major areas of investigation: liquid fossil fuel cycle; extraction (resource assessment, enhanced recovery); liquid processing (characterization of petroleum and synthetic crude, thermodynamics; process technology); utilization; project integration and technology transfer. Highlights for this period in research studies are listed as those in extraction research and processing and thermodynamics research. Searches for microorganisms that will be useful in enhanced oil recovery have produced two promising leads. At Oklahoma State University, bacteria of the genus Clostridia have been found which can live in a brine solution as found in most petroleum reservoirs. These bacteria produce carbon dioxide, acetic acid, alcohols, and ketones as metabolic products. At the University of Georgia, a culture of bacteria has been found which will reduce the viscosity of a 10/sup 0/ API gravity oil by 95 percent. The analysis of heavy oils requires differentiation of sulfur, nitrogen, and oxygen-containing compounds from hydrocarbons. The most effective way to do this is with a high-resolution mass spectrometer that can distinguish between compounds having molecular weights only a fractional unit apart. These molecular weights are calculated from the computer acquired time-moments of the various ions in a mass spectrum. Thus, the accuracy of results reflects, in part, the numerical methods used in data processing. Consequently, the effect of the mathematical functions on the accuracy of mass measurement is being determined.

Improving the Carbon Dioxide Emission Estimates from the Combustion of Fossil Fuels in California  

SciTech Connect (OSTI)

Central to any study of climate change is the development of an emission inventory that identifies and quantifies the State's primary anthropogenic sources and sinks of greenhouse gas (GHG) emissions. CO2 emissions from fossil fuel combustion accounted for 80 percent of California GHG emissions (CARB, 2007a). Even though these CO2 emissions are well characterized in the existing state inventory, there still exist significant sources of uncertainties regarding their accuracy. This report evaluates the CO2 emissions accounting based on the California Energy Balance database (CALEB) developed by Lawrence Berkeley National Laboratory (LBNL), in terms of what improvements are needed and where uncertainties lie. The estimated uncertainty for total CO2 emissions ranges between -21 and +37 million metric tons (Mt), or -6percent and +11percent of total CO2 emissions. The report also identifies where improvements are needed for the upcoming updates of CALEB. However, it is worth noting that the California Air Resources Board (CARB) GHG inventory did not use CALEB data for all combustion estimates. Therefore the range in uncertainty estimated in this report does not apply to the CARB's GHG inventory. As much as possible, additional data sources used by CARB in the development of its GHG inventory are summarized in this report for consideration in future updates to CALEB.

Innovative fossil fuel fired vitrification technology for soil remediation. Phase 1  

SciTech Connect (OSTI)

Vortec has successfully completed Phase 1 of the ``Innovative Fossil Fuel Fired Vitrification Technology for Soil Remediation`` program. The Combustion and Melting System (CMS) has processed 7000 pounds of material representative of contaminated soil that is found at DOE sites. The soil was spiked with Resource Conservation and Recovery Act (RCRA) metals surrogates, an organic contaminant, and a surrogate radionuclide. The samples taken during the tests confirmed that virtually all of the radionuclide was retained in the glass and that it did not leach to the environment-as confirmed by both ANS 16.1 and Toxicity Characteristic Leaching Procedure (TCLP) testing. The organic contaminant, anthracene, was destroyed during the test with a Destruction and Removal Efficiency (DRE) of at least 99.99%. RCRA metal surrogates, that were in the vitrified product, were retained and did not leach to the environment as confirmed by the TCLP testing. Semi-volatile RCRA metal surrogates were captured by the Air Pollution Control (APC) system, and data on the amount of metal oxide particulate and the chemical composition of the particulate were established for use in the Phase 2 APC subsystem design.

Analysis of possible future atmospheric retention of fossil fuel CO/sub 2/  

SciTech Connect (OSTI)

This report investigates the likely rates and the potential range of future CO/sub 2/ emissions, combined with knowledge of the global cycle of carbon, to estimate a possible range of future atmospheric CO/sub 2/ concentrations through the year 2075. Historic fossil fuel usage to the present, growing at a rate of 4.5% per year until 1973 and at a slower rate of 1.9% after 1973, was combined with three scenarios of projected emissions growth ranging from approximately 0.2 to 2.8% per year to provide annual CO/sub 2/ emissions data for two different carbon cycle models. The emissions scenarios were constructed using an energy-economic model and by varying key parameters within the bounds of currently expected future values. The extreme values for CO/sub 2/ emissions in the year 2075 are 6.8 x 10/sup 15/ and 91 x 10/sup 15/ g C year/sup -1/. Carbon cycle model simulations used a range of year - 1800 preindustrial atmospheric concentrations of 245 to 292 ppM CO/sub 2/ and three scenarios of bioshere conversion as additional atmospheric CO/sub 2/ source terms. These simulations yield a range of possible atmospheric CO/sub 2/ concentrations in year 2075 of approximately 500 to 1500 ppM, with a median of about 700 ppM. The time at which atmospheric CO/sub 2/ would potentially double from the preindustrial level ranges from year 2025 to >2075. The practical, programmatic value of this forecast exercise is that it forces quantitative definition of the assumptions, and the uncertainties therein, which form the basis of our understanding of the natural biogeochemical cycle of carbon and both historic and future human influences on the dynamics of the global cycle. Assumptions about the possible range of future atmospheric CO/sub 2/ levels provide a basis on which to evaluate the implications of these changes on climate and the biosphere. 44 references, 17 figures, 21 tables.

Summary of research on hydrogen production from fossil fuels conducted at NETL  

SciTech Connect (OSTI)

In this presentation we will summarize the work performed at NETL on the production of hydrogen via partial oxidation/dry reforming of methane and catalytic decomposition of hydrogen sulfide. We have determined that high pressure resulted in greater carbon formation on the reforming catalysts, lower methane and CO2 conversions, as well as a H2/CO ratio. The results also showed that Rh/alumina catalyst is the most resistant toward carbon deposition both at lower and at higher pressures. We studied the catalytic partial oxidation of methane over Ni-MgO solid solutions supported on metal foams and the results showed that the foam-supported catalysts reach near-equilibrium conversions of methane and H2/CO selectivities. The rates of carbon deposition differ greatly among the catalysts, varying from 0.24 mg C/g cat h for the dipped foams to 7.0 mg C/g cat h for the powder-coated foams, suggesting that the exposed Cr on all of the foam samples may interact with the Ni-MgO catalyst to kinetically limit carbon formation. Effects of sulfur poisoning on reforming catalysts were studies and pulse sulfidation of catalyst appeared to be reversible for some of the catalysts but not for all. Under pulse sulfidation conditions, the 0.5%Rh/alumina and NiMg2Ox-1100C (solid solution) catalysts were fully regenerated after reduction with hydrogen. Rh catalyst showed the best overall activity, less carbon deposition, both fresh and when it was exposed to pulses of H2S. Sulfidation under steady state conditions significantly reduced catalyst activity. Decomposition of hydrogen sulfide into hydrogen and sulfur was studied over several supported metal oxides and metal oxide catalysts at a temperature range of 650-850C. H2S conversions and effective activation energies were estimated using Arrhenius plots. The results of these studies will further our understanding of catalytic reactions and may help in developing better and robust catalysts for the production of hydrogen from fossil fuels

Cost-effective policy instruments for greenhouse gas emission reduction and fossil fuel substitution through bioenergy production in Austria  

Science Journals Connector (OSTI)

Climate change mitigation and security of energy supply are important targets of Austrian energy policy. Bioenergy production based on resources from agriculture and forestry is an important option for attaining these targets. To increase the share of bioenergy in the energy supply, supporting policy instruments are necessary. The cost-effectiveness of these instruments in attaining policy targets depends on the availability of bioenergy technologies. Advanced technologies such as second-generation biofuels, biomass gasification for power production, and bioenergy with carbon capture and storage (BECCS) will likely change the performance of policy instruments. This article assesses the cost-effectiveness of energy policy instruments, considering new bioenergy technologies for the year 2030, with respect to greenhouse gas emission (GHG) reduction and fossil fuel substitution. Instruments that directly subsidize bioenergy are compared with instruments that aim at reducing GHG emissions. A spatially explicit modeling approach is used to account for biomass supply and energy distribution costs in Austria. Results indicate that a carbon tax performs cost-effectively with respect to both policy targets if BECCS is not available. However, the availability of BECCS creates a trade-off between GHG emission reduction and fossil fuel substitution. Biofuel blending obligations are costly in terms of attaining the policy targets.

A simulator for training fossil-fuel power plants operators with an HMI based on a multi-window system  

Science Journals Connector (OSTI)

The hardware-software architecture for a power plant simulator is presented. The simulator is hosted in a local area network of personal computers and has Windows XP as its operating system. The Human-Machine Interfaces (HMIs) for the operator and the instructor are based on a multi-window system; therefore, they have access to a lot of information inside their respective action field at any moment during the simulation session. In particular, the operator HMI has been designed for being suitable for training power plants operators with modern HMIs, where the operation is based on computer screens. The simulator has been installed in an operators training centre where a group of acceptance tests has been successfully carried out. Currently, the simulator is being used as part of the training courses for fossil-fuel power plant operators.

A multiresolution spatial parametrization for the estimation of fossil-fuel carbon dioxide emissions via atmospheric inversions.  

SciTech Connect (OSTI)

The estimation of fossil-fuel CO2 emissions (ffCO2) from limited ground-based and satellite measurements of CO2 concentrations will form a key component of the monitoring of treaties aimed at the abatement of greenhouse gas emissions. To that end, we construct a multiresolution spatial parametrization for fossil-fuel CO2 emissions (ffCO2), to be used in atmospheric inversions. Such a parametrization does not currently exist. The parametrization uses wavelets to accurately capture the multiscale, nonstationary nature of ffCO2 emissions and employs proxies of human habitation, e.g., images of lights at night and maps of built-up areas to reduce the dimensionality of the multiresolution parametrization. The parametrization is used in a synthetic data inversion to test its suitability for use in atmospheric inverse problem. This linear inverse problem is predicated on observations of ffCO2 concentrations collected at measurement towers. We adapt a convex optimization technique, commonly used in the reconstruction of compressively sensed images, to perform sparse reconstruction of the time-variant ffCO2 emission field. We also borrow concepts from compressive sensing to impose boundary conditions i.e., to limit ffCO2 emissions within an irregularly shaped region (the United States, in our case). We find that the optimization algorithm performs a data-driven sparsification of the spatial parametrization and retains only of those wavelets whose weights could be estimated from the observations. Further, our method for the imposition of boundary conditions leads to a 10computational saving over conventional means of doing so. We conclude with a discussion of the accuracy of the estimated emissions and the suitability of the spatial parametrization for use in inverse problems with a significant degree of regularization.

On the environmental, economic and budgetary impacts of fossil fuel prices: A dynamic general equilibrium analysis of the Portuguese case  

Science Journals Connector (OSTI)

Abstract This paper examines the influence of fossil fuel prices on carbon dioxide emissions, economic activity, and the public sector account in Portugal. It uses a dynamic general equilibrium model which highlights the mechanisms of endogenous growth and includes a detailed modeling of the public sector. Fuel price scenarios are based on forecasts by the US Department of Energy (DOE-US), the International Energy Agency (IEA-OECD) and IHS Global Insight Inc. The differences in relative fuel prices among the three scenarios lead to substantially different environmental impacts. Higher fuel prices in the DOE-US scenario lead to a 10.2% reduction in the policy effort required to meet the EU 2020 emission targets, while relative price changes in the IEA-OECD scenario result in a 19.2% increase in the required policy effort and decreasing fuel prices increase the emissions deficit by 95.9% under the IHS scenario. In terms of the long term economic impacts, our results suggest a 2.2% reduction in GDP in the DOE-US scenario and 1.9% in the IEA-OECD scenario and an increase of 1.4% in the IHS scenario. As to the budgetary impact, higher fuel prices lead to lower tax revenues, which, coupled with a reduction in public spending translates to lower public deficits. From a methodological perspective, our results highlight the importance of the mechanisms of endogenous growth. A scenario of higher fuel prices would, under exogenous economic growth assumptions, result in larger baseline emissions growth, substantially smaller economic effects, and rather different budgetary effects. From a policy perspective, our results highlight the importance of fossil fuel prices in defining the level of policy intervention required for compliance with international and domestic climate change legislation.

Carbon emission and mitigation cost comparisons between fossil fuel, nuclear and renewable energy resources for electricity generation  

Science Journals Connector (OSTI)

A study was conducted to compare the electricity generation costs of a number of current commercial technologies with technologies expected to become commercially available within the coming decade or so. The amount of greenhouse gas emissions resulting per kWh of electricity generated were evaluated. A range of fossil fuel alternatives (with and without physical carbon sequestration), were compared with the baseline case of a pulverised coal, steam cycle power plant. Nuclear, hydro, wind, bioenergy and solar generating plants were also evaluated. The objectives were to assess the comparative costs of mitigation per tonne of carbon emissions avoided, and to estimate the total amount of carbon mitigation that could result from the global electricity sector by 2010 and 2020 as a result of fuel switching, carbon dioxide sequestration and the greater uptake of renewable energy. Most technologies showed potential to reduce both generating costs and carbon emission avoidance by 2020 with the exception of solar power and carbon dioxide sequestration. The global electricity industry has potential to reduce its carbon emissions by over 15% by 2020 together with cost saving benefits compared with existing generation.

Problems of attracting nuclear energy resources in order to provide economical and rational consumption of fossil fuels  

Science Journals Connector (OSTI)

Depletion of fossil fuels resources and the gradual increase in cost of their extraction and transportation to the places of their consumption put forward into a line of the most urgent tasks the problem of rational and economical utilization of fuel and energy resources, as well as introduction of new energy sources into various sectors of the national economy. The nuclear energy sources which are widely spread in power engineering have not yet been used to a proper extent in the sectors of industrial technologies and residentidal space heating, which are the most energy consuming sectors in the national economy. The most effective way of solving this problem can be the development and commercialization of high temperature nuclear reactors, as the majority of power consuming industrial processes and those involved in chemico-thermal systems of distant heat transmission demand the temperature of a heat carrier generated by nuclear reactors and assimilated by the above processes to be in the range from 900 to 1000C.

Effects of aqueous effluents from in situ fossil fuel processing technologies on aquatic systems. Annual progress report, January 1-December 31, 1979  

SciTech Connect (OSTI)

This is the third annual progress report for a continuing EPA-DOE jointly funded project to evaluate the effects of aqueous effluents from in situ fossil-fuel processing technologies on aquatic biota. The project is organized into four project tasks: (1) literature review; (2) process water screening; (3) methods development; and (4) recommendations. Our Bibliography of aquatic ecosystem effects, analytical methods and treatment technologies for organic compounds in advanced fossil-fuel processing effluents was submitted to the EPA for publication. The bibliography contains 1314 citations indexed by chemicals, keywords, taxa and authors. We estimate that the second bibliography volume will contain approximately 1500 citations and be completed in February. We compiled results from several laboratories of inorganic characterizations of 19 process waters: 55 simulated in situ oil-shale retort waters; and Hanna-3, Hanna-4B 01W and Lawrence Livermore Hoe Creek underground coal gasification condenser waters. These process waters were then compared to a published summary of the analyses from 18 simulated in situ oil-shale retort waters. We completed this year 96-h flow-through toxicity bioassays with fathead minnows and rainbow trout and 48-h flow-through bioassays with Daphnia pulicaria exposed to 5 oil-shale process waters, 1 tar-sand process water, 2 underground coal gasification condenser waters, 1 post-gasification backflood condenser water, as well as 2 bioassays with fossil-fuel process water constituents. The LC/sub 50/ toxicity values for these respective species when exposed to these waters are given in detail. (LTN)

Burns Burns Burns can result from everyday things and activities in your home. The most common causes of burns are from scalds (steam, hot bath water, hot drinks and foods), fire, chemicals, electricity and overexposure to the sun. Some burns may be more serious than others. The severity of the burn is based on the depth of the burn. First degree burns are the least severe, and third degree burns are the most severe. Call 911 or seek medical attention if you are unsure of how severe your burn is. All burns are susceptible to tetanus (lockjaw). Get a tetanus shot every 10 years. If your last shot was 5 years ago, talk to your doctor - you may need a booster shot.

Innovative fossil fuel fired vitrification technology for soil remediation. Volume 1, Phase 1: Annual report, September 28, 1992--August 31, 1993  

SciTech Connect (OSTI)

Vortex has successfully completed Phase 1 of the ``Innovative Fossil Fuel Fired Vitrification Technology for Soil Remediation`` program with the Department of Energy (DOE) Morgantown Energy Technology Center (METC). The Combustion and Melting System (CMS) has processed 7000 pounds of material representative of contaminated soil that is found at DOE sites. The soil was spiked with Resource Conversation and Recovery Act (RCRA) metals surrogates, an organic contaminant, and a surrogate radionuclide. The samples taken during the tests confirmed that virtually all of the radionuclide was retained in the glass and that it did not leach to the environment. The organic contaminant, anthracene, was destroyed during the test with a Destruction and Removal Efficiency (DRE) of at least 99.99%. RCRA metal surrogates, that were in the vitrified product, were retained and will not leach to the environment--as confirmed by the TCLP testing. Semi-volatile RCRA metal surrogates were captured by the Air Pollution Control (APC) system, and data on the amount of metal oxide particulate and the chemical composition of the particulate were established for use in the Phase 2 APC system design. This topical report will present a summary of the activities conducted during Phase 1 of the ``Innovative Fossil Fuel Fired Vitrification Technology for Soil Remediation`` program. The report includes the detail technical data generated during the experimental program and the design and cost data for the preliminary Phase 2 plant.

Energy, environmental, health and cost benefits of cogeneration from fossil fuels and nuclear energy using the electrical utility facilities of a province  

Science Journals Connector (OSTI)

A method is investigated for increasing the utilization efficiency of energy resources and reducing environmental emissions, focusing on utility-scale cogeneration and the contributions of nuclear energy. A case study is presented for Ontario using the nuclear and fossil facilities of the main provincial electrical utility. Implementation of utility-based cogeneration in Ontario or a region with a similar energy system and attributes is seen to be able to reduce significantly annual and cumulative uranium and fossil fuel use and related emissions, provide economic benefits for the province and its electrical utility, and substitute nuclear energy for fossil fuels. The reduced emissions of greenhouse gases are significant, and indicate that utility-based cogeneration can contribute notably to efforts to combat climate change. Ontario and other regions with similar energy systems and characteristics would benefit from working with the regional electrical utilities and other relevant parties to implementing cogeneration in a careful and optimal manner. Implementation decisions need to balance the interests of the stakeholders when determining which cogeneration options to adopt and barriers to regional utility-based cogeneration need to be overcome.

Assessment of the impacts on health due to the emissions of Cuban power plants that use fossil fuel oils with high content of sulfur. Estimation of external costs  

Science Journals Connector (OSTI)

Fossil fuel electricity generation has been demonstrated to be a main source of atmospheric pollution. The necessity of finding out a balance between the costs of achieving a lower level of environmental and health injury and the benefits of providing electricity at a reasonable cost have lead to the process of estimating the external costs derived from these impacts and not included in the electricity prices as a quantitative measure of it that, even when there are large uncertainties involved, can be used by decision makers in the process of achieving a global sustainable development. The external costs of the electricity generation in three Cuban power plants that use fossil fuel oils with high sulfur content have been assessed. With that purpose a specific implementation of the Impact Pathways Methodology for atmospheric emissions was developed. Dispersion of atmospheric pollutants is modeled at local and regional scales in a detailed way. Health impacts include mortality and those morbidity effects that showed relation with the increment of selected pollutant concentration in national studies. The external cost assessed for the three plants was 40,588,309USDyr?1 (min./max.: 10,194,833/169,013,252), representing 1.06USDCentkWh?1. Costs derived from sulfur species (SO2 and sulfate aerosol) stand for 93% of the total costs.

Dispersion modeling of polycyclic aromatic hydrocarbons from combustion of biomass and fossil fuels and production of coke in Tianjin, China  

SciTech Connect (OSTI)

A USEPA procedure, ISCLT3 (Industrial Source Complex Long-Term), was applied to model the spatial distribution of polycyclic aromatic hydrocarbons (PAHs) emitted from various sources including coal, petroleum, natural gas, and biomass into the atmosphere of Tianjin, China. Benzo(a)pyrene equivalent concentrations (BaPeq) were calculated for risk assessment. Model results were provisionally validated for concentrations and profiles based on the observed data at two monitoring stations. The dominant emission sources in the area were domestic coal combustion, coke production, and biomass burning. Mainly because of the difference in the emission heights, the contributions of various sources to the average concentrations at receptors differ from proportions emitted. The shares of domestic coal increased from {approximately} 43% at the sources to 56% at the receptors, while the contributions of coking industry decreased from {approximately} 23% at the sources to 7% at the receptors. The spatial distributions of gaseous and particulate PAHs were similar, with higher concentrations occurring within urban districts because of domestic coal combustion. With relatively smaller contributions, the other minor sources had limited influences on the overall spatial distribution. The calculated average BaPeq value in air was 2.54 {+-} 2.87 ng/m{sup 3} on an annual basis. Although only 2.3% of the area in Tianjin exceeded the national standard of 10 ng/m{sup 3}, 41% of the entire population lives within this area. 37 refs., 9 figs.

An empirical investigation of air pollution from fossil fuel combustion and its impact on health in India during 19731974 to 19961997  

Science Journals Connector (OSTI)

Many air pollution studies examine impacts on global climate warming in the future, but impacts on health of population are more actual and concrete. The aim of this paper is to evaluate air pollution (CO2, SO2, and NOx) from fossil fuel combustion in India. InputOutput Structural Decomposition Analysis approach is used to find out their sources of changes. We also estimate the emissions of CO2, SO2 and \\{NOx\\} for the year 20012002 and 20062007. A link between emission of pollutants and their impact on human health is finally analysed. The study categorizes the changes in the amount of CO2, SO2 and \\{NOx\\} emissions into four factors: the pollution intensity or eco-efficiency, technology or input-mix, composition of final demand, and the level of final demand. The main factors for these changes were the pollution intensity, technology, and the volume of final demand. Changes in the pollution intensity and technology were in most periods increasing air pollution. These results are quite different to those observed in some other studies. Pollution and health impacts have a close linear relationship and the main factors for the changes are the same as for the pollution.

Strategic backdrop analysis for fossil fuel planning. Task 2 report (New Task Series), The Base Case. Report 473-117-08/01  

SciTech Connect (OSTI)

This report describes a base case analysis performed using the strategic backdrop analytical framework developed by The Futures Group to facilitate fossil fuel planning within the Department of Energy. It builds upon the data base compiled in the default case previously submitted but uses a different set of energy technology assumptions. Objectives of the strategic backdrop analysis project are: (1) to delineate alternative socioeconomic futures or target worlds for the United States and to derive, for each world, the amount of energy needed to sustain its level of economic activity and lifestyle, assuming no technological changes; (2) to construct an analytical framework that accounts for the flow of energy from the disaggregated end-use target demand sectors back through the distribution and conversion processes to primary resource requirements; (3) to use this framework 1) to analyze how alternative government policies and associated new technologies can change the primary resource needs and fuel mix while still providing the same level of end-use energy service for the target world, and 2) to highlight resource constraints, program inconsistencies, and economic, environmental, and social implications; (4) to transfer to DOE personnel the methodology for generating energy targets and accounting for important characteristics of alternative energy policies and technologies.

Sensitivity of global-scale climate change attribution results to inclusion of fossil fuel black carbon aerosol - article no. L14701  

SciTech Connect (OSTI)

It is likely that greenhouse gas emissions caused most of the global mean warming observed during the 20th century, and that sulphate aerosols counteracted this warming to some extent, by reflecting solar radiation to space and thereby cooling the planet. However, the importance of another aerosol, namely black carbon, could be underestimated. Here we include fossil fuel black carbon aerosol in a detection and attribution analysis with greenhouse gas and sulphate aerosols. We find that most of the warming of the 20th Century is attributable to changes in greenhouse gases offset by net aerosol cooling. However the pattern of temperature change due to black carbon is currently indistinguishable from the sulphate aerosol pattern of temperature change. The attribution of temperature change due to greenhouse gases is not sensitive to the inclusion of black carbon. We can be confident about the overall attribution of total aerosols, but less so about the contributions of black carbon emissions to 20th century climate change. This work presents no evidence that black carbon aerosol forcing outweighed the cooling due to sulphate aerosol.

Extension of energy crops on surplus agricultural lands: A potentially viable option in developing countries while fossil fuel reserves are diminishing  

Science Journals Connector (OSTI)

Abstract The rapid depletion of fossil fuel reserves and environmental concerns with their combustion necessitate looking for alternative sources for long term sustainability of the world. These concerns also appear serious in developing countries who are striving for rapid economic growth. The net biomass growing potential on the global land surface is 10 times more than the global food, feed, fiber, and energy demands. This study investigates whether the developing countries have sufficient land resource to meet the projected energy demand towards 2035 by planting energy crops on surplus agricultural land after food and feed production. The annual yields of four commonly grown energy crops specifically jatropha, switchgrass, miscanthus, and willow have been used to make scenarios and estimate land requirements against each scenario. This paper first performs literature reviews on the availability of land resource, past and future trends in land use changes, demand of lands for food production, and potential expansion of croplands. The energy demands towards 2035 are compiled from energy scenarios derived by the International Energy Agency (IEA) and the British Petroleum (BP). This paper also reviewed bio-physiological characteristics of these energy crops to determine whether they are cultivable under tropical climatic conditions in developing regions. This paper found that projected energy demand through 2035 in developing regions could be provided by energy crops grown on a portion of surplus croplands or upgraded grasslands (27% and 22% respectively for miscanthus scenario). Sustainable land management practices, improved agricultural productivity, and adopting suitable energy crops cultivation can potentially supply increasing energy demands.

A research needs assessment for the capture, utilization and disposal of carbon dioxide from fossil fuel-fired power plants. Volume 1, Executive summary: Final report  

SciTech Connect (OSTI)

This study identifies and assesses system approaches in order to prioritize research needs for the capture and non-atmospheric sequestering of a significant portion of the carbon dioxide (CO{sub 2}) emitted from fossil fuel-fired electric power plants (US power plants presently produce about 7% of the world`s CO{sub 2} emissions). The study considers capture technologies applicable either to existing plants or to those that optimistically might be demonstrated on a commercial scale over the next twenty years. Specific conclusions are as follows: (1) To implement CO{sub 2} capture and sequestration on a national scale will decrease power plant net efficiencies and significantly increase the cost of electricity. To make responsible societal decisions, accurate and consistent economic and environmental analysis of all alternatives for atmospheric CO{sub 2} mitigation are required. (2) Commercial CO{sub 2} capture technology, though expensive and energy intensive, exists today. (3) The most promising approach to more economical CO{sub 2} capture is to develop power plant systems that facilitate efficient CO{sub 2} capture. (4) While CO{sub 2} disposal in depleted oil and gas reservoirs is feasible today, the ability to dispose of large quantities Of CO{sub 2} is highly uncertain because of both technical and institutional issues. Disposal into the deep ocean or confined aquifers offers the potential for large quantity disposal, but there are technical, safety, liability, and environmental issues to resolve. Therefore, the highest priority research should focus on establishing the feasibility of large scale disposal options.

Sulfur accumulation in pinewood (Pinus sylvestris) induced by bacteria in a simulated seabed environment: Implications for marine archaeological wood and fossil fuels  

Science Journals Connector (OSTI)

Fresh pinewood blocks were submerged in sulfate and iron(II) containing media, inoculated with bacterial consortia isolated from seawater, aiming to simulate the seabed conditions of the Vasa shipwreck (1628). The consortia contained erosion (EB) and sulfate-reducing bacteria (SRB). Sulfur K-edge X-ray absorption near edge structure (XANES) spectroscopy and scanning X-ray spectromicroscopy images showed that organic sulfur, mainly thiols (R-SH), had accumulated in the lignin-rich middle lamella in EB-degraded parts of the wood. The sulfur content in the wood increased more than 10 times in 2 years. In another series with active inoculums from marine archaeological wood, the sulfur XANES spectra showed, after 4 years of anaerobic treatment, considerable amounts also of inorganic iron sulfides, Fe1?xS, which oxidized at atmospheric exposure. A sediment sample from the Vasa's seabed was also rich in iron sulfides, including pyrite, FeS2. X-ray fluorescence mappings of sulfur and phosphorous distributions indicate that scavenging SRB penetration, producing hydrogen sulfide in situ, is restricted to EB-degraded parts of the wood structure. The sulfur isotope depletion of 34S from ?34S=21 in marine sulfate to ?34S=6 and 1.8 for fractions of reduced sulfur and sulfate separated from a Vasa wood sample, respectively, suggests bacterial transformation. A fuller understanding of the routes of sulfur accumulation, as reactive iron sulfides and as organic sulfur, has important implications for improving conservation methods of marine archaeological wood. Moreover, the biogenic accumulation of organically bound sulfur, specifically in lignin-rich parts of waterlogged wood, has wider geochemical significance for fossil fuels of marine origin, as lignin-rich humic matter is important for the diagenetic formation of kerogens from anoxic marine sediments.

Problems in squeeze cementing  

SciTech Connect (OSTI)

For the past half century, work has been carried out to improve squeeze cementing. During the course of time, new techniques, equipment, cement and cement additives were introduced. Work is still underway to improve squeeze cementing. Basic concept of squeeze cementing, understanding the problems, planning for a squeeze job and then later testing of the job help in achieving the goal. Solutions were offered to some common problems, whereas many regional problems need time to time study and effort. Squeezing long perforations in highly permeable sand has always been a problem, for which some techniques were presented.

This report describes results of a technical, financial and environmental assessment study for a project, which would have included a new TCS micronized coal-fired heating plant for the Produkcja I Hodowla Roslin Ogrodniczych (PHRO) Greenhouse Complex; Krzeszowice, Poland. Project site is about 20 miles west of Krakow, Poland. During the project study period, PHRO utilized 14 heavy oil-fired boilers to produce heat for its greenhouse facilities and also home heating to several adjacent apartment housing complexes. The boilers burn a high-sulfur content heavy crude oil, called mazute, The project study was conducted during a period extended from March 1996 through February 1997. For size orientation, the PHRO Greenhouse complex grows a variety of vegetables and flowers for the Southern Poland marketplace. The greenhouse area under glass is very large and equivalent to approximately 50 football fields, The new micronized coal fired boiler would have: (1) provided a significant portion of the heat for PHRO and a portion of the adjacent apartment housing complexes, (2) dramatically reduced sulfur dioxide air pollution emissions, while satisfying new Polish air regulations, and (3) provided attractive savings to PHRO, based on the quantity of displaced oil.

The objective of this project is to develop an improved ultra-lightweight cement using ultra-lightweight hollow glass spheres (ULHS). Work reported herein addresses tasks performed in the fourth quarter as well as the other three quarters of the past year. The subjects that were covered in previous reports and that are also discussed in this report include: Analysis of field laboratory data of active cement applications from three oil-well service companies; Preliminary findings from a literature review focusing on problems associated with ultra-lightweight cements; Summary of pertinent information from Russian ultra-lightweight cement literature review; and Comparison of compressive strengths of ULHS systems using ultrasonic and crush methods Results reported from the fourth quarter include laboratory testing of ULHS systems along with other lightweight cement systems--foamed and sodium silicate slurries. These comparison studies were completed for two different densities (10.0 and 11.5 lb/gal) and three different field application scenarios. Additional testing included the mechanical properties of ULHS systems and other lightweight systems. Studies were also performed to examine the effect that circulation by centrifugal pump during mixing has on breakage of ULHS.

US fossil fuel technologies for Thailand  

SciTech Connect (OSTI)

The US Department of Energy has been encouraging other countries to consider US coal and coal technologies in meeting their future energy needs. Thailand is one of three developing countries determined to be a potentially favorable market for such exports. This report briefly profiles Thailand with respect to population, employment, energy infrastructure and policies, as well as financial, economic, and trade issues. Thailand is shifting from a traditionally agrarian economy to one based more strongly on light manufacturing and will therefore require increased energy resources that are reliable and flexible in responding to anticipated growth. Thailand has extensive lignite deposits that could fuel a variety of coal-based technologies. Atmospheric fluidized-bed combustors could utilize this resource and still permit Thailand to meet emission standards for sulfur dioxide. This option also lends itself to small-scale applications suitable for private-sector power generation. Slagging combustors and coal-water mixtures also appear to have potential. Both new construction and refurbishment of existing plants are planned. 18 refs., 3 figs., 7 tabs.

Fireside corrosion probes for fossil fuel combustion  

SciTech Connect (OSTI)

Electrochemical corrosion rate probes have been constructed and tested along with mass loss coupons in environments consisting of N2/O2/CO2/SO2 plus water vapor. Temperatures ranged from 450 to 700C. Results show that electrochemical corrosion rates for ash-covered mild steel are a function of time, temperature, and gaseous environment. Correlation between the electrochemical and mass loss corrosion rates was poor.

The Potential for Increased Atmospheric CO2 Emissions and Accelerated Consumption of Deep Geologic CO2 Storage Resources Resulting from the Large-Scale Deployment of a CCS-Enabled Unconventional Fossil Fuels Industry in the U.S.  

SciTech Connect (OSTI)

Desires to enhance the energy security of the United States have spurred significant interest in the development of abundant domestic heavy hydrocarbon resources including oil shale and coal to produce unconventional liquid fuels to supplement conventional oil supplies. However, the production processes for these unconventional fossil fuels create large quantities of carbon dioxide (CO2) and this remains one of the key arguments against such development. Carbon dioxide capture and storage (CCS) technologies could reduce these emissions and preliminary analysis of regional CO2 storage capacity in locations where such facilities might be sited within the U.S. indicates that there appears to be sufficient storage capacity, primarily in deep saline formations, to accommodate the CO2 from these industries. Nevertheless, even assuming wide-scale availability of cost-effective CO2 capture and geologic storage resources, the emergence of a domestic U.S. oil shale or coal-to-liquids (CTL) industry would be responsible for significant increases in CO2 emissions to the atmosphere. The authors present modeling results of two future hypothetical climate policy scenarios that indicate that the oil shale production facilities required to produce 3MMB/d from the Eocene Green River Formation of the western U.S. using an in situ retorting process would result in net emissions to the atmosphere of between 3000-7000 MtCO2, in addition to storing potentially 900-5000 MtCO2 in regional deep geologic formations via CCS in the period up to 2050. A similarly sized, but geographically more dispersed domestic CTL industry could result in 4000-5000 MtCO2 emitted to the atmosphere in addition to potentially 21,000-22,000 MtCO2 stored in regional deep geologic formations over the same period. While this analysis shows that there is likely adequate CO2 storage capacity in the regions where these technologies are likely to deploy, the reliance by these industries on large-scale CCS could result in an accelerated rate of utilization of the nations CO2 storage resource, leaving less high-quality storage capacity for other carbon-producing industries including electric power generation.

Thermal Shock-resistant Cement  

SciTech Connect (OSTI)

We studied the effectiveness of sodium silicate-activated Class F fly ash in improving the thermal shock resistance and in extending the onset of hydration of Secar #80 refractory cement. When the dry mix cement, consisting of Secar #80, Class F fly ash, and sodium silicate, came in contact with water, NaOH derived from the dissolution of sodium silicate preferentially reacted with Class F fly ash, rather than the #80, to dissociate silicate anions from Class F fly ash. Then, these dissociated silicate ions delayed significantly the hydration of #80 possessing a rapid setting behavior. We undertook a multiple heating -water cooling quenching-cycle test to evaluate the cements resistance to thermal shock. In one cycle, we heated the 200 and #61616;C-autoclaved cement at 500 and #61616;C for 24 hours, and then the heated cement was rapidly immersed in water at 25 and #61616;C. This cycle was repeated five times. The phase composition of the autoclaved #80/Class F fly ash blend cements comprised four crystalline hydration products, boehmite, katoite, hydrogrossular, and hydroxysodalite, responsible for strengthening cement. After a test of 5-cycle heat-water quenching, we observed three crystalline phase-transformations in this autoclaved cement: boehmite and #61614; and #61543;-Al2O3, katoite and #61614; calcite, and hydroxysodalite and #61614; carbonated sodalite. Among those, the hydroxysodalite and #61614; carbonated sodalite transformation not only played a pivotal role in densifying the cementitious structure and in sustaining the original compressive strength developed after autoclaving, but also offered an improved resistance of the #80 cement to thermal shock. In contrast, autoclaved Class G well cement with and without Class F fly ash and quartz flour failed this cycle test, generating multiple cracks in the cement. The major reason for such impairment was the hydration of lime derived from the dehydroxylation of portlandite formed in the autoclaved cement, causing its volume to expand.

Sun tanning/burning Sun tanning/burning Name: Richardo Cossyleon Location: N/A Country: N/A Date: N/A Question: Why doesn't the sun affect or burn people with dark pigment in their skin? Replies: Good question! The pigment, melanin, is more toward the surface of the upper skin layer and absorbs ultraviolet rays from the Sun or artificial sources. This absorption protects the lower layers from damage and inflammation (burning). A very dark skinned person may have over a 1000X the protection from UV compared to a fair skinned person. Fair skinned people should use sun-block lotions especially early in the warm season AND keep exposure to the sun, particularly at midday, to less than 30 min. Even if a person gets a good tan, the sun's UV will age the skin over time. It will get wrinkled and develop age lines, etc. after many years of exposure. Moderation is the key!

Exergy analysis of cement production  

Science Journals Connector (OSTI)

In the present paper, cement production in Greece has been examined using the exergy analysis methodology. The major goal of the modern cement and concrete production industry is the minimisation of energy costs and environmental effects. The rational management of raw materials and energy requires analytical decision making tools that will provide the necessary information for the identification of possible improvements in the life cycle of a product. The second law of Thermodynamics allows for the evaluation of the irreversibility and the exergetic performance of a process. The analysis involves assessment of energy and exergy input at each stage of the cement production process. The chemical exergy of the reaction is also calculated and taken into consideration. It is found that 50% of the exergy is being lost even though a big amount of waste heat is being recovered.

Evaluation of cement production using a pressurized fluidized-bed combustor  

SciTech Connect (OSTI)

There are several primary conclusions which can be reached and used to define research required in establishing the feasibility of using PFBC-derived materials as cement feedstock. 1. With appropriate blending almost any material containing the required cement-making materials can be utilized to manufacture cement. However, extensive blending with multiple materials or the use of ash in relatively small quantities would compromise the worth of this concept. 2. The composition of a potential feedstock must be considered not only with respect to the presence of required materials, but just as significantly, with respect to the presence and concentration of known deleterious materials. 3. The processing costs for rendering the feedstock into an acceptable composition and the energy costs associated with both processing and burning must be considered. It should be noted that the cost of energy to produce cement, expressed as a percentage of the price of the product is higher than for any other major industrial product. Energy consumption is, therefore, a major issue. 4. The need for conformance to environmental regulations has a profound effect on the cement industry since waste materials can neither be discharged to the atmosphere or be shipped to a landfill. 5. Fifth, the need for achieving uniformity in the composition of the cement is critical to controlling its quality. Unfortunately, certain materials in very small concentrations have the capability to affect the rate and extent to which the cementitious compound in portland cement are able to form. Particularly critical are variations in the ash, the sulfur content of the coal or the amount and composition of the stack dust returned to the kiln.

Biomass burning and global change  

Science Journals Connector (OSTI)

The burning of living and dead biomass including forests savanna grasslands and agricultural wastes is much more widespread and extensive than previously believed and may consume as much as 8700 teragrams of dry biomass matter per year. The burning of this much biomass releases about 3940 teragrams of total carbon or about 3550 teragrams of carbon in the form of CO2 which is about 40% of the total global annual production of CO2. Biomass burning may also produce about 32% of the worlds annual production of CO 24% of the nonmethane hydrocarbons 20% of the oxides of nitrogen and biomass burn combustion products may be responsible for producing about 38% of the ozone in the troposphere. Biomass burning has increased with time and today is overwhelmingly human?initiated.

Synthesis of belite cement clinker of high hydraulic reactivity  

SciTech Connect (OSTI)

This study is concerned with the increase of the cooling rate of belite clinker, by using the water quenching for the chemical stabilization of reactive belite, which improves the hydraulic properties of this clinker. The addition of adequate mineralizers, as NaF and Fe{sub 2}O{sub 3}, contributes to the improvement of the clinker properties obtained at low burning temperature. X-ray fluorescence spectroscopy, X-ray diffraction analysis and optical microscopy were used to determine the chemical and mineralogical compositions of this clinker. The samples were analyzed by means of a scanning electronic microscope connected with an energy-dispersive X-ray spectrometer to detect the composition of the belite phase and its morphology. Physical and mechanical properties of this clinker cement were determined. The results show that the belite clinker obtained at 1150 {sup o}C, with lime saturation factor 0.67, is characterized by a great hydraulic reactivity, similar to that of the ordinary alite clinker.

HYDRAULIC CEMENT PREPARATION FROM LURGI SPENT SHALE  

SciTech Connect (OSTI)

Low cost material is needed for grouting abandoned retorts. Experimental work has shown that a hydraulic cement can be produced from Lurgi spent shale by mixing it in a 1:1 weight ratio with limestone and heating one hour at 1000C. With 5% added gypsum, strengths up to 25.8 MPa are obtained. This cement could make an economical addition up to about 10% to spent shale grout mixes, or be used in ordinary cement applications.

Permeability of consolidated incinerator facility wastes stabilized with portland cement  

SciTech Connect (OSTI)

The Consolidated Incinerator Facility (CIF) at the Savannah River Site (SRS) burns low-level radioactive wastes and mixed wastes as a method of treatment and volume reduction. The CIF generates secondary waste, which consists of ash and offgas scrubber solution. Currently the ash is stabilized/solidified in the Ashcrete process. The scrubber solution (blowdown) is sent to the SRS Effluent Treatment Facility (ETF) for treatment as wastewater. In the past, the scrubber solution was also stabilized/solidified in the Ashcrete process as blowcrete, and will continue to be treated this way for listed waste burns and scrubber solutions that do not meet the ETF Waste Acceptance Criteria (WAC). The disposal plan for Ashcrete and special case blowcrete is to bury these containerized waste forms in shallow unlined trenches in E-Area. The WAC for intimately mixed, cement-based wasteforms intended for direct disposal specifies limits on compressive strength and permeability. Simulated waste and actual CIF ash and scrubber solution were mixed in the laboratory and cast into wasteforms for testing. Test results and related waste disposal consequences are given in this report.

Comparing soil carbon of short rotation poplar plantations with agricultural crops and woodlots in north central United States.  

SciTech Connect (OSTI)

Atmospheric carbon dioxide (CO2) has increased dramatically since the beginning of the Industrial Revolution as a result of human activities (Keeling and others 1995, Houghton and others 2001). The primary cause of CO2 increases are worldwide fossil fuel burning, biomass burning, and cement manufacturing. These activities are, in turn, tied to the expanding world population and a rising demand for energy. If the steady increase of CO2 continues, there may be profound effects on the environment and the world economy from a "greenhouse effect" that has led to global warming of the atmosphere (Houghton and others 2001).

Fracture model for cemented aggregates  

DOE Public Access Gateway for Energy & Science Beta (PAGES Beta)

A mechanisms-based fracture model applicable to a broad class of cemented aggregates and, among them, plastic-bonded explosive (PBX) composites, is presented. The model is calibrated for PBX 9502 using the available experimental data under uniaxial compression and tension gathered at various strain rates and temperatures. We show that the model correctly captures inelastic stress-strain responses prior to the load peak and it predicts the post-critical macro-fracture processes, which result from the growth and coalescence of micro-cracks. In our approach, the fracture zone is embedded into elastic matrix and effectively weakens the material's strength along the plane of the dominant fracture.

Wood would burn  

Science Journals Connector (OSTI)

Absract In view of the world-wide problem of energy sustainability and greenhouse gas production (carbon dioxide), it is timely to review the issues involved in generating heat and power from all fuels and especially new (to the UK) solid fuels, including high moisture fuels such as wood, SRF, oil shale, tar sands and brown coal, which will become major international fuels as oil and gas become depleted. The combustion properties of some of these materials are significantly different from traditional coal, oil and gas fuels, however the technology proposed herein is also applicable to these conventional fuels. This paper presents some innovative combustion system options and the associated technical factors that must be considered for their implementation. For clarity of understanding, the novel concepts will be largely presented in terms of a currently developing solid fuel market; biomass wood chips. One of the most important characteristics of many solid fuels to be used in the future (including oil shale and brown coal) is their high moisture content of up to 60%. This could be removed by utilising low grade waste heat that is widely available in industry to dry the fuel and thus reduce transport costs. Burning such dried wood for power generation also increases the energy available from combustion and thus acts as a thermal transformer by upgrading the low grade heat to heat available at combustion temperatures. The alternative approach presented here is to recover the latent heat by condensing the extrinsic moisture and the water formed during combustion. For atmospheric combustion, the temperature of the condensed combustion products is below the dew point at about 5565C and is only suitable for recovery in an efficient district heating system. However, in order to generate power from the latent heat, the condensation temperature must be increased to the level where the heat can be used in the thermodynamic power cycle. This can be achieved by increasing the combustion pressure to above 80bar, resulting in the recovered latent heat being available at more than 200C. It can then be used to increase the cycle efficiency by about 15% by pre-heating the boiler water and/or combustion air etc. A further advantage is that the high pressure of the combustion gases also reduces the superheater tube stress since it can balance the steam pressure. The key advantage of this high pressure flue gas is that it is above the pressure at which carbon dioxide condenses to a liquid or supercritical gas at atmospheric temperature. Thus when used with oxy-fuel combustion, the carbon dioxide flue gas from which the moisture has been condensed can be cooled to atmospheric temperature and the supercritical CO2 can be fed directly into the pipes leading to the sequestration site. An important consideration of these strategies is to ensure that non-condensable gases in the exhaust, including oxygen and nitrogen, do not adversely affect the condensation processes. When oxy-fuel combustion is used, the flame temperature must be moderated by a cool diluent. Recycled carbon dioxide is often proposed for this duty. However, since the latent heat is recovered, the moisture or even additional water can fulfil this role. This latter option may be advantageous since it is more efficient to pump wood chip fuel in water into the high pressure zone rather than feed solid wood particles. Surplus water can be simply drained and the wet wood chips are a good fuel when the latent heat of the moisture in the fuel gases is recovered into the power cycle. Bearing in mind that it is much more efficient to pump a liquid to high pressure than to compress the same material as a gas, indicates that cryogenic oxygen is a suitable material to use for an efficient power station that generates energy from biomass (or other fuels such as coal etc). Finally, combustion of the hydrogen from the watergas reaction with oxygen allows the steam temperature in the turbine to be increased to the gas-turbine engine range of 10001400C an

Assessment of halite-cemented reservoir zones  

SciTech Connect (OSTI)

This paper describes the techniques used to identify the presence and distribution of halite-cemented layers in a sandstone oil reservoir. The distribution of these layers in the wells was found by matching the core data with two independent halite identifiers from the well logs. Numerical well models were used to assess the dimensions and spatial distribution of the halite-cemented layers. Multiple simulation runs in which the spatial distribution, the dimensions, and the vertical permeability were varied resulted in a stochastic model that best matched the production history. Gas and water coning are retarded by the halite-cemented layers if the perforations are properly located.

Timing is everything : along the fossil fuel transition pathway.  

SciTech Connect (OSTI)

People save for retirement throughout their career because it is virtually impossible to save all you'll need in retirement the year before you retire. Similarly, without installing incremental amounts of clean fossil, renewable or transformative energy technologies throughout the coming decades, a radical and immediate change will be near impossible the year before a policy goal is set to be in place. Therefore, our research question is,To meet our desired technical and policy goals, what are the factors that affect the rate we must install technology to achieve these goals in the coming decades?' Existing models do not include full regulatory constraints due to their often complex, and inflexible approaches to solve foroptimal' engineering instead ofrobust' and multidisciplinary solutions. This project outlines the theory and then develops an applied software tool to model the laboratory-to-market transition using the traditional technology readiness level (TRL) framework, but develops subsequent and a novel regulatory readiness level (RRL) and market readiness level (MRL). This tool uses the ideally-suited system dynamics framework to incorporate feedbacks and time delays. Future energy-economic-environment models, regardless of their programming platform, may adapt this software model component framework ormodule' to further vet the likelihood of new or innovative technology moving through the laboratory, regulatory and market space. The prototype analytical framework and tool, called the Technology, Regulatory and Market Readiness Level simulation model (TRMsim) illustrates the interaction between technology research, application, policy and market dynamics as they relate to a new or innovative technology moving from the theoretical stage to full market deployment. The initial results that illustrate the model's capabilities indicate for a hypothetical technology, that increasing the key driver behind each of the TRL, RRL and MRL components individually decreases the time required for the technology to progress through each component by 63, 68 and 64%, respectively. Therefore, under the current working assumptions, to decrease the time it may take for a technology to move from the conceptual stage to full scale market adoption one might consider expending additional effort to secure regulatory approval and reducing the uncertainty of the technology's demand in the marketplace.

NEW OPTICAL SENSOR SUITE FOR ULTRAHIGH TEMPERATURE FOSSIL FUEL APPLICATIONS  

SciTech Connect (OSTI)

Accomplishments during the Phase I of a program to develop and demonstrate technology for the instrumentation of advanced powerplants are described. Engineers from Prime Research, LC and Babcock and Wilcox Research Center collaborated to generate a list of potential applications for robust photonic sensors in existing and future boiler plants. From that list, three applications were identified as primary candidates for initial development and demonstration of high-temperature sensors in an ultrasupercritical power plant. A matrix of potential fiber optic sensor approaches was derived, and a data set of specifications for high-temperature optical fiber was produced. Several fiber optic sensor configurations, including interferometric (extrinsic and intrinsic Fabry-Perot interferometer), gratings (fiber Bragg gratings and long period gratings), and microbend sensors, were evaluated in the laboratory. In addition, progress was made in the development of materials and methods to apply high-temperature optical claddings to sapphire fibers, in order to improve their optical waveguiding properties so that they can be used in the design and fabrication of high-temperature sensors. Through refinements in the processing steps, the quality of the interface between core and cladding of the fibers was improved, which is expected to reduce scattering and attenuation in the fibers. Numerical aperture measurements of both clad and unclad sapphire fibers were obtained and used to estimate the reduction in mode volume afforded by the cladding. High-temperature sensors based on sapphire fibers were also investigated. The fabrication of an intrinsic Fabry-Perot cavity within sapphire fibers was attempted by the bulk diffusion of magnesium oxide into short localized segments of longer sapphire fibers. Fourier analysis of the fringes that resulted when the treated fiber was interrogated by a swept laser spectrometer suggested that an intrinsic cavity had been formed in the fiber. Also, an unclad sapphire fiber was tested as a temperature sensor at moderate temperatures (up to 775 C).

Comprehensive monitoring program for fossil fuel utility boilers  

SciTech Connect (OSTI)

Kentucky Utilities Company (KUCo) is an investor-owned electric utility serving customers in 78 Kentucky counties and through a subsidiary, Old Dominion Power Company, serves customers in five counties in southwestern Virginia. Over 99 percent of all electricity generated is from coal. KUCo has five coal-fired generating stations with a total generating capacity of 2,530,000 kilowatts. According to regulations adopted by the Kentucky Division of Air Pollution (DAP), each existing, indirect heat exchanger having a capacity factor greater than thirty percent is required to install, operate and maintain continuous opacity and sulfur dioxide monitoring equipment. Newer units already had continuous emission monitors (CEM's) and they were also required to monitor for nitrogen oxides. When the CEM retro-fit project was started in the spring of 1980, the operating status, as well as the manufacturer and model numbers of existing equipment, were identified. Approximately 80 percent of the existing equipment was manufactured by Lear Siegler, Inc. (LSI). Most of the LSI equipment was operable and it was determined that LSI equipment would be used for the retro-fit project. Existing equipment was renovated to include recent design changes and improvements and some equipment supplied by others was replaced.

Innovative Fresh Water Production Process for Fossil Fuel Plants  

SciTech Connect (OSTI)

This project concerns a diffusion driven desalination (DDD) process where warm water is evaporated into a low humidity air stream, and the vapor is condensed out to produce distilled water. Although the process has a low fresh water to feed water conversion efficiency, it has been demonstrated that this process can potentially produce low cost distilled water when driven by low grade waste heat. This report summarizes the progress made in the development and analysis of a Diffusion Driven Desalination (DDD) system. Detailed heat and mass transfer analyses required to size and analyze the diffusion tower using a heated water input are described. The analyses agree quite well with the current data and the information available in the literature. The direct contact condenser has also been thoroughly analyzed and the system performance at optimal operating conditions has been considered using a heated water/ambient air input to the diffusion tower. The diffusion tower has also been analyzed using a heated air input. The DDD laboratory facility has successfully been modified to include an air heating section. Experiments have been conducted over a range of parameters for two different cases: heated air/heated water and heated air/ambient water. A theoretical heat and mass transfer model has been examined for both of these cases and agreement between the experimental and theoretical data is good. A parametric study reveals that for every liquid mass flux there is an air mass flux value where the diffusion tower energy consumption is minimal and an air mass flux where the fresh water production flux is maximized. A study was also performed to compare the DDD process with different inlet operating conditions as well as different packing. It is shown that the heated air/heated water case is more capable of greater fresh water production with the same energy consumption than the ambient air/heated water process at high liquid mass flux. It is also shown that there can be significant advantage when using the heated air/heated water process with a less dense less specific surface area packed bed. Use of one configuration over the other depends upon the environment and the desired operating conditions.

Advanced Hydrogen Transport Membranes for Vision 21 Fossil Fuel Plants  

SciTech Connect (OSTI)

The objective of this project was to develop an environmentally benign, inexpensive, and efficient method for separating hydrogen from gas mixtures produced during industrial processes, such as coal gasification. A family of hydrogen separation membranes was developed including single phase mixed conducting ceramics, ceramic/ceramic composites, cermet membranes, cermet membranes containing a hydrogen permeable metal, and intermediate temperature composite layered membranes. Each membrane type had different operating parameters, advantages, and disadvantages that were documented over the course of the project. Research on these membranes progressed from ceramics to cermets to intermediate temperature composite layered membranes. During this progression performance was increased from 0.01 mL x min{sup -1} x cm{sup -2} up to 423 mL x min{sup -1} x cm{sup -2}. Eltron and team membranes not only developed each membrane type, but also membrane surface catalysis and impurity tolerance, creation of thin film membranes, alternative applications such as membrane promoted alkane dehydrogenation, demonstration of scale-up testing, and complete engineering documentation including process and mechanical considerations necessary for inclusion of Eltron membranes in a full scale integrated gasification combined cycle power plant. The results of this project directly led to a new $15 million program funded by the Department of Energy. This new project will focus exclusively on scale-up of this technology as part of the FutureGen initiative.

Novel Gas Sensors for High-Temperature Fossil Fuel Applications  

SciTech Connect (OSTI)

SRI International (SRI) is developing ceramic-based microsensors to detect exhaust gases such as NO, NO{sub 2}, and CO in advanced combustion and gasification systems under this DOE NETL-sponsored research project. The sensors detect the electrochemical activity of the exhaust gas species on catalytic electrodes attached to a solid state electrolyte and are designed to operate at the high temperatures, elevated pressures, and corrosive environments typical of large power generation exhausts. The sensors can be easily integrated into online monitoring systems for active emission control. The ultimate objective is to develop sensors for multiple gas detection in a single package, along with data acquisition and control software and hardware, so that the information can be used for closed-loop control in novel advanced power generation systems. This report details the Phase I Proof-of-Concept, research activities performed from October 2003 to March 2005. SRI's research work includes synthesis of catalytic materials, sensor design and fabrication, software development, and demonstration of pulse voltammetric analysis of NO, NO{sub 2}, and CO gases on catalytic electrodes.

Environmental impact of fossil fuel combustion in power generation  

SciTech Connect (OSTI)

All the recent developments in the combustion systems employed for power generation have been based on environmental considerations. Combustion modifications have been developed and utilised in order to control NO{sub x} emissions and improvements continue to be made as the legislative requirements tighten. Chemical processes and fuel switching are used to control SO{sub x} emissions. After nitrogen, carbon dioxide is the major gas emitted from the combustion process and its potential potency as a greenhouse gas is well documented. Increased efficiency cycles, mainly based on natural gas as the prime fuel, can minimise the amount of CO{sub x} produced per unit of power generated. As the economics of natural gas utilisation become less favourable a return to clean coal technology based power generation processes may be required.

Actinide Burning in CANDU Reactors  

SciTech Connect (OSTI)

Actinide burning in CANDU reactors has been studied as a method of reducing the actinide content of spent nuclear fuel from light water reactors, and thereby decreasing the associated long term decay heat load. In this work simulations were performed of actinides mixed with natural uranium to form a mixed oxide (MOX) fuel, and also mixed with silicon carbide to form an inert matrix (IMF) fuel. Both of these fuels were taken to a higher burnup than has previously been studied. The total transuranic element destruction calculated was 40% for the MOX fuel and 71% for the IMF. (authors)

Hot corrosion tests on corrosion resistant coatings developed for gas turbines burning biomass and waste derived fuel gases  

Science Journals Connector (OSTI)

Abstract This paper reports on results of hot corrosion tests carried out on siliconaluminide coatings developed for hot components of gas turbines burning biomass and waste derived fuel gases. The corrosion tests of the siliconaluminide coatings, applied to superalloys IN738LC and CMSX-4, each consisted of five 100h periods; at 700C for the type II tests and at 900C for the type I tests. Deposits of Cd+ alkali and Pb+ alkali were applied before each exposure. These deposits had been previously identified as being trace species produced from gasification of biomass containing fuels which after combustion had the potential to initiate hot corrosion in a gas turbine. Additionally, gases were supplied to the furnace to simulate the atmosphere anticipated post-combustion of these biomass derived fuel gases. Results of the type I hot corrosion tests showed that these novel coatings remained in the incubation stage for at least 300h, after which some of the coating entered propagation. Mass change results for the first 100h confirmed this early incubation stage. For the type II hot corrosion tests, differences occurred in oxidation and sulphidation rates between the two substrates; the incubation stages for CMSX-4 samples continued for all but the Cd+ alkali high salt flux samples, whereas, for IN738LC, all samples exhibited consistent incubation rates. Following both the type I and type II corrosion tests, assessments using BSE/EDX results and XRD analysis confirmed that there has to be remnant coating, sufficient to grow a protective scale. In this study, the novel siliconaluminide coating development was based on coating technology originally evolved for gas turbines burning natural gas and fossil fuel oils. So in this paper comparisons of performance have been made with three commercially available coatings; a CoCrAlY overlay, a platinum-aluminide diffusion, and triple layer nickelaluminide/siliconaluminide-diffusion coatings. These comparisons showed that the novel single-step siliconaluminide coatings provide equal or superior type II hot corrosion resistance to the best of the commercial coatings.

Pollution by cereal waste burning in Spain  

Science Journals Connector (OSTI)

In this paper, the amount of cereal waste burned in Spain, which represents the most important source of biomass burning in this country, is estimated. During the period between 1980 and 1998, an average mass of 8 Tg of cereal waste was burned annually, with remaining 1 Tg of ash on the cereal fields after combustion. By using emission factors previously calculated by Ortiz de Zrate et al. [Ortiz de Zrate, I., Ezcurra, A., Lacaux, J.P., Van Dihn, P., 2000. Emission factor estimates of cereal waste burning in Spain. Atmos. Environ. 34, 31833193.], it is deduced that pollutant emissions linked to cereal waste-burning process reach values of 11 Tg CO2, 80 Gg of TPM and 23 Gg of \\{NOx\\} year?1 during the cereal-burning period. These emissions represent 46% of total CO2 and 23% \\{NOx\\} emitted in Spain during the burning period that lasts 1 month after harvesting. Therefore, the relative importance of cereal waste burning as pollutant source in Spain almost during fire period becomes evident. Finally, our study allows to deduce that the production of 1 kg of cereal crop implies that 410 g of carbon and 3.3 g of nitrogen are going to be introduced into the atmosphere by this pollutant process. We estimate a total gaseous emission of 3.3 Tg of C and 25 Gg N as different pollutants by cereal waste burning.

Uniform-burning matrix burner  

DOE Patents [OSTI]

Computer simulation was used in the development of an inward-burning, radial matrix gas burner and heat pipe heat exchanger. The burner and exchanger can be used to heat a Stirling engine on cloudy days when a solar dish, the normal source of heat, cannot be used. Geometrical requirements of the application forced the use of the inward burning approach, which presents difficulty in achieving a good flow distribution and air/fuel mixing. The present invention solved the problem by providing a plenum with just the right properties, which include good flow distribution and good air/fuel mixing with minimum residence time. CFD simulations were also used to help design the primary heat exchanger needed for this application which includes a plurality of pins emanating from the heat pipe. The system uses multiple inlet ports, an extended distance from the fuel inlet to the burner matrix, flow divider vanes, and a ring-shaped, porous grid to obtain a high-temperature uniform-heat radial burner. Ideal applications include dish/Stirling engines, steam reforming of hydrocarbons, glass working, and any process requiring high temperature heating of the outside surface of a cylindrical surface.

Capture of green-house carbon dioxide in Portland cement  

SciTech Connect (OSTI)

A novel process has been developed to sequester green-house carbon dioxide produced by the cement industry in precast cement products. Typically, 10--24 wt % of CO{sub 2} produced by calcination of calcium carbonate during clinkering of the cement may be captured. The carbonation process also cures the cement paste within minutes into hard bodies. The process maintains high pH conditions during curing, to allow conventional steel reinforcement of concrete. The process will save time and money to the cement industry, and at the same time, help them to comply with the Clean Air Act by sequestering the green-house carbon dioxide.

Inexpensive cement is needed to grout abandoned in-situ retorts of spent shale for subsidence control, mitigation of leaching, and strengthening the retorted mass in order to recover oil from adjacent pillars of raw shale. A hydraulic cement was produced by heating a 1:1 mixture of Lurgi spent shale and CaCO{sub 3} at 1000 C for one hour. This cement would be less expensive than ordinary portland cement and is expected to fulfill the above requirements.

Comparison of modified sulfur cement and hydraulic cement for encapsulation of radioactive and mixed wastes  

SciTech Connect (OSTI)

The majority of solidification/stabilization systems for low-level radioactive waste (LLW) and mixed waste, both in the commercial sector and at Department of Energy (DOE) facilities, utilize hydraulic cement (such as portland cement) to encapsulate waste materials and yield a monolithic solid waste form for disposal. A new and innovative process utilizing modified sulfur cement developed by the US Bureau of Mines has been applied at Brookhaven National Laboratory (BNL) for the encapsulation of many of these problem'' wastes. Modified sulfur cement is a thermoplastic material, and as such, it can be heated above it's melting point (120{degree}C), combined with dry waste products to form a homogeneous mixture, and cooled to form a monolithic solid product. Under sponsorship of the DOE, research and development efforts at BNL have successfully applied the modified sulfur cement process for treatment of a range of LLWs including sodium sulfate salts, boric acid salts, and incinerator bottom ash and for mixed waste contaminated incinerator fly ash. Process development studies were conducted to determine optimal waste loadings for each waste type. Property evaluation studies were conducted to test waste form behavior under disposal conditions by applying relevant performance testing criteria established by the Nuclear Regulatory Commission (for LLW) and the Environmental Protection Agency (for hazardous wastes). Based on both processing and performance considerations, significantly greater waste loadings were achieved using modified sulfur cement when compared with hydraulic cement. Technology demonstration of the modified sulfur cement encapsulation system using production-scale equipment is scheduled for FY 1991. 12 refs., 8 figs., 3 tabs.

Investigation of benefit of using coal wastes in cement production  

Science Journals Connector (OSTI)

Waste disposal in coal preparation plants leads to serious environmental problems. These wastes usually contain about 20% carbon, and the composition of the remaining ash is similar to clay. Addition of these wastes to cement clinker raw material utilises carbon as a source of energy. In this investigation, the effect of addition of these waste materials to the raw materials used in cement manufacture is studied. Ordinary type II cement and sulphoaluminate cement may be produced from the wastes. Mechanical strength, chemical and phase analysis, setting time and particle size distribution of the cement were studied. The results of the experiments show that an addition of about 3% of the coal wastes to the raw materials used in cement manufacture produces cements with good quality. Further, energy consumption may be reduced by up to 15%.

GHG Information GHG Information Energy Footprints DOE developed a series of Energy Footprints to map the flow of energy supply and demand in U.S. manufacturing industries. Identifying the sources and end uses of energy helps to pinpoint areas of energy intensity and characterize the unique energy needs of individual industries. On the supply side, the footprints provide details on the energy purchased from utilities (electricity, fossil fuels), energy generated onsite, and excess energy transported to the local grid. On the demand side, the footprints illustrate where and how energy is used within a typical plant, from central boilers to motors. Most important, the footprints identify where energy is lost due to inefficiencies, both inside and outside the plant boundary. Considerable energy is lost, for example, in steam and

Health Hazard Evaluation determination report HHE 81-000-113, Martin-Marietta Cement, Tulsa, Oklahoma  

SciTech Connect (OSTI)

In response to a request from the United Cement, Lime, Gypsum and Allied Workers Union Local 421, an investigation was made of possible health hazards occurring from the burning of high sulfur coal which exposed workers to sulfur-dioxide, carbon-dioxide, and hydrogen-sulfide at Martin-Marietta Cement, Tulsa, Oklahoma. Mail questionnaires were sent to employees prior to a hazard survey, and were followed up with medical interviews focusing on neurological symptoms, syncope, strokes, chest pain, and mucous membrane irritation. Environmental samples were collected for sulfur-dioxide, sulfates, sulfites, carbon-monoxide, nitrogen-dioxide, and hydrogen-sulfide, and measured predominately in work areas near the back end of the kiln. Eighteen of 29 questionnaire respondents and 20 of 21 interviewed workers reported mucous membrane irritation compatible with sulfur-dioxide exposure. The NIOSH recommended limit for sulfur-dioxide was 0.5ppm as a time weighted average. The authors conclude that a health hazard did exist at the time of the survey, and recommend that controls be implemented to minimize sulfur-dioxide exposure in the facility.

Effective Permeability Change in Wellbore Cement with Carbon Dioxide Reaction  

SciTech Connect (OSTI)

Portland cement, a common sealing material for wellbores for geological carbon sequestration was reacted with CO{sub 2} in supercritical, gaseous, and aqueous phases at various pressure and temperature conditions to simulate cement-CO{sub 2} reaction along the wellbore from carbon injection depth to the near-surface. Hydrated Portland cement columns (14 mm diameter x 90 mm length; water-to-cement ratio = 0.33) including additives such as steel coupons and Wallula basalt fragments were reacted with CO{sub 2} in the wet supercritical (the top half) and dissolved (the bottom half) phases under carbon sequestration condition with high pressure (10 MPa) and temperature (50 C) for 5 months, while small-sized hydrated Portland cement columns (7 mm diameter x 20 mm length; water-to-cement ratio = 0.38) were reacted with CO{sub 2} in dissolved phase at high pressure (10 MPa) and temperature (50 C) for 1 month or with wet CO{sub 2} in gaseous phase at low pressure (0.2 MPa) and temperature (20 C) for 3 months. XMT images reveal that the cement reacted with CO{sub 2} saturated groundwater had degradation depth of {approx}1 mm for 1 month and {approx}3.5 mm for 5 month, whereas the degradation was minor with cement exposure to supercritical CO{sub 2}. SEM-EDS analysis showed that the carbonated cement was comprised of three distinct zones; the innermost less degraded zone with Ca atom % > C atom %, the inner degraded zone with Ca atom % {approx} C atom % due to precipitation of calcite, the outer degraded zone with C atom % > Ca atom % due to dissolution of calcite and C-S-H, as well as adsorption of carbon to cement matrix. The outer degraded zone of carbonated cement was porous and fractured because of dissolution-dominated reaction by carbonic acid exposure, which resulted in the increase in BJH pore volume and BET surface area. In contrast, cement-wet CO{sub 2}(g) reaction at low P (0.2 MPa)-T (20 C) conditions for 1 to 3 months was dominated by precipitation of micron-sized calcite on the outside surface of cement, which resulted in the decrease in BJH pore volume and BET surface area. Cement carbonation and pore structure change are significantly dependent on pressure and temperature conditions as well as the phase of CO{sub 2}, which controls the balance between precipitation and dissolution in cement matrix. Geochemical modeling result suggests that ratio of solid (cement)-to-solution (carbonated water) has a significant effect on cement carbonation, thus the cement-CO{sub 2} reaction experiment needs to be conducted under realistic conditions representing the in-situ wellbore environment of carbon sequestration field site. Total porosity and air permeability for a duplicate cement column with water-to-cement ratio of 0.38 measured after oven-drying by Core Laboratories using Boyle's Law technique and steady-state method were 31% and 0.576 mD. A novel method to measure the effective liquid permeability of a cement column using X-ray micro-tomography images after injection of pressurized KI (potassium iodide) is under development by PNNL. Preliminary results indicate the permeability of a cement column with water-to-cement ratio of 0.38 is 4-8 mD. PNNL will apply the method to understand the effective permeability change of Portland cement by CO{sub 2}(g) reaction under a variety of pressure and temperature conditions to develop a more reliable well-bore leakage risk model.

Treatment of a severe alkali burn  

Science Journals Connector (OSTI)

The case history of a 20-year-old male patient who sustained an 85 per cent total body surface area alkali burn to his skin, after falling into a caustic lime pit, is reported. Considerable problems regarding the correct estimate of burn wound depth, predominant location of the deepest burn on the posterior half of the body, appropriate wound coverage, and lack of sufficient skin graft donor sites required a complex treatment plan. Excisions to fascia and intradermal debridement were required to achieve an appropriate bed for wound closure. Five per cent mafenide acetate solution (Sulfamylon) was applied to prevent burn wound sepsis. Human allografts and Biobrane were used extensively to achieve temporary wound closure, to provide mechanical protection of freshly autografted wounds, and to prevent desiccation following application of cultured epidermal autografts on to debrided wounds and split thickness skin grafted donor sites. The case illustrates a number of problems associated with the evaluation and treatment of patients suffering severe alkali burns, and demonstrates the implementation of both established and evolving technologies in the management of these injuries.

Guidebook for Using the Tool BEST Cement: Benchmarking and Energy Savings Tool for the Cement Industry  

SciTech Connect (OSTI)

The Benchmarking and Energy Savings Tool (BEST) Cement is a process-based tool based on commercially available efficiency technologies used anywhere in the world applicable to the cement industry. This version has been designed for use in China. No actual cement facility with every single efficiency measure included in the benchmark will likely exist; however, the benchmark sets a reasonable standard by which to compare for plants striving to be the best. The energy consumption of the benchmark facility differs due to differences in processing at a given cement facility. The tool accounts for most of these variables and allows the user to adapt the model to operational variables specific for his/her cement facility. Figure 1 shows the boundaries included in a plant modeled by BEST Cement. In order to model the benchmark, i.e., the most energy efficient cement facility, so that it represents a facility similar to the user's cement facility, the user is first required to input production variables in the input sheet (see Section 6 for more information on how to input variables). These variables allow the tool to estimate a benchmark facility that is similar to the user's cement plant, giving a better picture of the potential for that particular facility, rather than benchmarking against a generic one. The input variables required include the following: (1) the amount of raw materials used in tonnes per year (limestone, gypsum, clay minerals, iron ore, blast furnace slag, fly ash, slag from other industries, natural pozzolans, limestone powder (used post-clinker stage), municipal wastes and others); the amount of raw materials that are preblended (prehomogenized and proportioned) and crushed (in tonnes per year); (2) the amount of additives that are dried and ground (in tonnes per year); (3) the production of clinker (in tonnes per year) from each kiln by kiln type; (4) the amount of raw materials, coal and clinker that is ground by mill type (in tonnes per year); (5) the amount of production of cement by type and grade (in tonnes per year); (6) the electricity generated onsite; and, (7) the energy used by fuel type; and, the amount (in RMB per year) spent on energy. The tool offers the user the opportunity to do a quick assessment or a more detailed assessment--this choice will determine the level of detail of the energy input. The detailed assessment will require energy data for each stage of production while the quick assessment will require only total energy used at the entire facility (see Section 6 for more details on quick versus detailed assessments). The benchmarking tool provides two benchmarks--one for Chinese best practices and one for international best practices. Section 2 describes the differences between these two and how each benchmark was calculated. The tool also asks for a target input by the user for the user to set goals for the facility.

Geophysical investigation of burn pit, 128-H-1, 100-H Area  

SciTech Connect (OSTI)

The 128-H-1 burn pit is located in the northeast corner of 100-H Area. The objective of the survey was to delineate subsurface features in the 128-H-1 burn pit that may affect the emplacement of soil-gas probes. Ground-penetrating radar (GPR) and electromagnetic induction (EMI) were the two techniques used in the investigation. The methods were selected because they are non-intrusive, relatively fast, economical, and have been used successfully in other geophysical investigations on the Hanford Site. The GPR system used for this work utilized a 300-MHz antenna to transmit the Em energy into the ground. The transmitted energy is reflected back to a receiving antenna where variations in the return signal are recorded. Common reflectors include natural geologic conditions such as bedding, cementation, moisture, and clay, or man-made objects such as pipes, barrels, foundations, and buried wires. The studied depth, which varies from site to site, was 0--11 ft for this survey. The method is limited in depth by transmit power, receiver sensitivity, and attenuation of the transmitted energy. Depth of investigation is influenced by highly conductive material, such as metal drums, which reflect all the energy back to the receiver. Therefore, the method cannot ``see`` below such objects.

Magnesium phosphate glass cements with ceramic-type properties  

DOE Patents [OSTI]

Rapid setting magnesium phosphate (Mg glass) cementitious materials consisting of magnesium phosphate cement paste, polyborax and water-saturated aggregate exhibiting rapid setting and high early strength characteristics. The magnesium glass cement is prepared from a cation-leachable powder and a bivalent metallic ion-accepting liquid such as an aqueous solution of diammonium phosphate and ammonium polyphosphate.

Energy Efficiency Improvement Opportunities for the Cement Industry  

SciTech Connect (OSTI)

This report provides information on the energy savings, costs, and carbon dioxide emissions reductions associated with implementation of a number of technologies and measures applicable to the cement industry. The technologies and measures include both state-of-the-art measures that are currently in use in cement enterprises worldwide as well as advanced measures that are either only in limited use or are near commercialization. This report focuses mainly on retrofit measures using commercially available technologies, but many of these technologies are applicable for new plants as well. Where possible, for each technology or measure, costs and energy savings per tonne of cement produced are estimated and then carbon dioxide emissions reductions are calculated based on the fuels used at the process step to which the technology or measure is applied. The analysis of cement kiln energy-efficiency opportunities is divided into technologies and measures that are applicable to the different stages of production and various kiln types used in China: raw materials (and fuel) preparation; clinker making (applicable to all kilns, rotary kilns only, vertical shaft kilns only); and finish grinding; as well as plant wide measures and product and feedstock changes that will reduce energy consumption for clinker making. Table 1 lists all measures in this report by process to which they apply, including plant wide measures and product or feedstock changes. Tables 2 through 8 provide the following information for each technology: fuel and electricity savings per tonne of cement; annual operating and capital costs per tonne of cement or estimated payback period; and, carbon dioxide emissions reductions for each measure applied to the production of cement. This information was originally collected for a report on the U.S. cement industry (Worrell and Galitsky, 2004) and a report on opportunities for China's cement kilns (Price and Galitsky, in press). The information provided in this report is based on publicly-available reports, journal articles, and case studies from applications of technologies around the world.

Polycyclic aromatic hydrocarbons (PAHs) in burning and non-burning coal waste piles  

Science Journals Connector (OSTI)

The coal waste material that results from Douro Coalfield exploitation was analyzed by gas chromatography with mass spectrometry (GCMS) for the identification and quantification of the 16 polycyclic aromatic hydrocarbons (PAHs), defined as priority pollutants. It is expected that the organic fraction of the coal waste material contains \\{PAHs\\} from petrogenic origin, and also from pyrolytic origin in burning coal waste piles. The results demonstrate some similarity in the studied samples, being phenanthrene the most abundant PAH followed by fluoranthene and pyrene. A petrogenic contribution of \\{PAHs\\} in unburned samples and a mixture of \\{PAHs\\} from petrogenic and pyrolytic sources in the burning/burnt samples were identified. The lowest values of the sum of the 16 priority \\{PAHs\\} found in burning/burnt samples and the depletion LMW \\{PAHs\\} and greater abundance of HMW \\{PAHs\\} from the unburned coal waste material relatively to the burning/burnt material demonstrate the thermal transformation attributed to the burning process. The potential environmental impact associated with the coal waste piles are related with the release of petrogenic and pyrolytic \\{PAHs\\} in particulate and gaseous forms to soils, sediments, groundwater, surface water, and biodiversity.

Potential for energy conservation in the cement industry  

SciTech Connect (OSTI)

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.

History and some potentials of oil shale cement  

SciTech Connect (OSTI)

The utilization of oil shale as a cement component is discussed. It was investigated in America and Europe during World War I. Additional development occurred in Western Europe, Russia, and China during the 1920s and 1930s. World War II provided further development incentives and a relatively mature technology was in place in Germany, Russia, and China prior to 1980. The utilization of oil shale in cement has taken a number of different paths. One approach has been to utilize the energy in the oil shale as the principal source for the cement plant and to use the combusted shale as a minor constituent of the plant's cement product. A second approach has been to use the combusted shale as a class C or cementitious fly-ash component in portland cement concrete. Other approaches utilizing eastern oil shale have been to use the combusted oil shale with additives as a specialty cement, or to cocombust the oil shale with coal and utilize the sulfur-rich combustion product.

Abstract: With the current focus on sustainability, it is necessary to evaluate cements environmental impact properly, especially when developing new green concrete types. Therefore, this chapter investigates the available literature on every process involved during the production of cement and its alternatives. A detailed study of ordinary Portland cements environmental impacts is followed by an assessment of improvement potentials which can be achieved with the use of supplementary cementitious materials. Finally, the environmental impacts of alternative binders such as sulfoaluminate or magnesia cements as well as alkali activated binders are studied.

Assessment of gas-side fouling in cement plants  

SciTech Connect (OSTI)

The purpose of this study is to provide an assessment of gas-side fouling in cement plants with special emphasis on heat recovery applications. Exhaust gases in the cement industry which are suitable for heat recovery range in temperature from about 400 to 1300 K, are generally dusty, may be highly abrasive, and are often heavily laden with alkalies, sulfates, and chlorides. Particulates in the exhaust streams range in size from molecular to about 100 ..mu..m in diameter and come from both the raw feed as well as the ash in the coal which is the primary fuel used in the cement industry. The major types of heat-transfer equipment used in the cement industry include preheaters, gas-to-air heat exchangers, waste heat boilers, and clinker coolers. The most important gas-side fouling mechanisms in the cement industry are those due to particulate, chemical reaction, and corrosion fouling. Particulate transport mechanisms which appear to be of greatest importance include laminar and turbulent mass transfer, thermophoresis, electrophoresis, and inertial impaction. Chemical reaction mechanisms of particular importance include the deposition of alkali sulfates, alkali chlorides, spurrite, calcium carbonate, and calcium sulfate. At sufficiently low temperatures, sulfuric acid and water can condense on heat exchanger surfaces which can cause corrosion and also attract particulates in the flow. The deleterious effects of gas-side fouling in cement plants are due to: (1) increased capital costs; (2) increased maintenance costs; (3) loss of production; and (4) energy losses. A conservative order-of-magnitude analysis shows that the cost of gas-side fouling in US cement plants is $0.24 billion annually.

Delayed ettringite formation (DEF) in mortars of white cement  

Science Journals Connector (OSTI)

In this study white cement CEM I-52.5 and white limestone cement CEM II-LL, A and B, with 15% and 25% limestone substitution, were studied. The way delayed ettringite forms, due to exposure to high temperatures (50C) and external sulphate attacks, was examined in the mortar samples. The mortars were immersed at 50C for 180days in: (a) a saturated Ca(OH)2 solution and (b) a 5% Na2SO4 solution. During the experiments duration, the mortar samples were being observed visually on a regular basis while their expansion was estimated on a weekly basis by measuring the change of length with a micrometer. At the end of the experiment, the mortar samples compressive strength was determined and the deterioration products were identified through means of X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM-EDAX), Thermogravimetry (TG) and Infra-Red Spectroscopy (FT-IR). Concluding it is evident that the amount of ettringite is proportional to the C3A content of cement. Sulphates amount in cement is the controlling factor for heat induced ettringite formation since when they are consumed the reaction stops. On the other hand in the case of external sulphate attack another important controlling factor is the compressive strength of the cement; the higher compressive strength the lower the risk of expansion. Finally, in the case of external sulphate attack, limestone, when added to cement, was proved to enhance the durability against sulphates attack when compared to a cement of the same class.

Initial Estimates of Mercury Emissions to the Atmosphere from Global Biomass Burning  

Science Journals Connector (OSTI)

Frequently burning grasslands in Africa and Australia, and agricultural waste burning globally, contribute relatively little to the mercury budget. ... Savannas burn frequently (intentionally or by accident), typically annually or biannually, while boreal forest burns at 50?200 year time scales, and wet tropical forests rarely burn at all. ... Total C emissions tracked burning in forested areas (including deforestation fires in the tropics), whereas burned area was largely controlled by savanna fires which responded to different environmental and human factors. ...

Expansion-contraction cycles for cement optimized as a function of additives  

SciTech Connect (OSTI)

An experimental study was carried out to investigate the addition of specific additives to cement in order to eliminate the micro-fractures and micro-annuli that cause gas migration. The experiments performed monitored the change in the cement slurry pressure during the setting of the cement. During the setting period of the cement, two time cycles of cement expansion and contraction were observed. This is due to the individual contributions of each part of the cement mixture. To obtain the optimum tightness of the cement, final optimum concentrations of the additives were obtained experimentally, where the cyclic pressure behavior of the cement was optimized for the best final cement results. By utilizing the correct amount of Anchorage Clay, XC-Polymer, Ironite Scavenger, Ultrafine cement and Synthetic Rubber powder in a class G mixture at a given temperature and confining pressure, an impermeable cement mixture can be obtained. The correct amount of Synthetic Rubber used for cyclic pressure reduction is a function of cement setting temperature and pressure as well as the elastic properties of the rubber. By using laboratory testing at different pressure and temperature with different rubber concentrations and elastic properties, it is estimated that the entire annulus can have an impermeable cement from surface to total depth. The difference in temperature and pressure with depth dictates the concentration and elastic properties of the rubber as the required expansion and contraction changes with depth.

Characteristics of hemp fabric reinforced nanoclaycement nanocomposites  

Science Journals Connector (OSTI)

Abstract Cement eco-nanocomposites reinforced with hemp fabric (HF) and nanoclay platelets (Cloisite 30B) are fabricated and investigated in terms of X-ray diffraction, scanning electron microscopy, physical and mechanical properties. Results indicated that the mechanical properties generally increased as a result of the addition of nanoclay into the cement matrix with HF. An optimum replacement of ordinary Portland cement with 1wt% nanoclay decreased the porosity and also significantly increased the density, flexural strength and fracture toughness of HF-reinforced nanocomposite. The microstructural results indicate that the nanoclay behaves not only as a filler to improve the microstructure, but also as an activator to promote the pozzolanic reaction and thus improved the adhesion with hemp fabric. The failure micromechanisms and energy dissipative processes in HF-reinforced cement composite and HF-reinforced nanocomposite are discussed in terms of microstructural observations. These cement eco-nanocomposites can provide new insights for the development of new environmental-friendly nanomaterials for building applications such as the construction of sandwich panels, ceilings and roofs.

Energy conservation potential of Portland cement particle size distribution control, Phase 2  

SciTech Connect (OSTI)

The main objectives of Phase 2 are to determine the feasibility of using cements with controlled particle size distributions (CPSD cements) in practical concrete applications, and to refine our estimates of the potential energy savings that may ensue from such use. The work in Phase 2 is divided into two main tasks, some parts of which will be carried out simultaneously: Task 1 will continue cement paste studies to optimize cement performance similar to those of Phase 1, but with particular emphasis on gypsum requirements, blended cements, and water-reducing admixtures. This task will also include preparation of sufficient CPSD cements for use in all Phase 2 work. Task 2 will be a comprehensive examination of the properties of concretes made with CPSD cements. This will include optimization of concrete mix designs to obtain the best possible performance for practical applications of both portland and blended cements. The effects of chemical admixtures and curing temperature variations will also be determined.

Monitoring the ettringite formation in cement paste using low field T2-NMR  

Science Journals Connector (OSTI)

In the present work we study the transverse relaxation time evolution of water molecules confined inside cement paste during the hydration process. The cement paste under study was manufactured with different water-to-cement ratios and using two types of cement: gray cement (CEM I 52.5 R) having a high content of magnetic impurities and white cement (CEM I 52.5 N) with lower amount of magnetic impurities. The two cement types were chosen in order to better distinguish the surface contribution to the relaxation process. On this basis a relationship between porosity evolution ettringite formation and the transverse relaxation time evolution was established. It was also observed that the increase in the water-to-cement ratio better reveals the ettringite formation.

Rapid setting of portland cement by greenhouse carbon dioxide capture  

SciTech Connect (OSTI)

Following the work by Berger et al. on rapid setting of calcium silicates by carbonation, a method of high-volume capture of CO{sub 2} in portland cement has been developed. Typically, 10--24 wt. % of CO{sub 2} produced by the calcination of calcium carbonate during clinkering, may be captured, and the set cement acquires most of its full strength in less than a day. The approach will have economic advantages in fabrication of precast structures, in emergency development of infrastructure during natural disasters, and in defense applications. Moreover, it will help the cement industry comply with the Clean Air Act of 1990 by sequestering the greenhouse carbon dioxide.

Results of source sampling at the Glens Falls cement kiln in Glens Falls, N.Y., are reported for sulfur oxides, ammonia, hydrochloric acid, oxygen, and moisture content. The origin of a detached, high-opacity, persistent plume originating from the cement kiln stack is investigated. It is proposed that this plume is due to ammonium salts of SOx and sulfuric acid that have been formed in condensed water droplets in the plume by the pseudocatalytic action of ammonia.

High Pressure Burn Rate Measurements on an Ammonium Perchlorate Propellant  

SciTech Connect (OSTI)

High pressure deflagration rate measurements of a unique ammonium perchlorate (AP) based propellant are required to design the base burn motor for a Raytheon weapon system. The results of these deflagration rate measurements will be key in assessing safety and performance of the system. In particular, the system may experience transient pressures on the order of 100's of MPa (10's kPSI). Previous studies on similar AP based materials demonstrate that low pressure (e.g. P < 10 MPa or 1500 PSI) burn rates can be quite different than the elevated pressure deflagration rate measurements (see References and HPP results discussed herein), hence elevated pressure measurements are necessary in order understand the deflagration behavior under relevant conditions. Previous work on explosives have shown that at 100's of MPa some explosives will transition from a laminar burn mechanism to a convective burn mechanism in a process termed deconsolidative burning. The resulting burn rates that are orders-of-magnitude faster than the laminar burn rates. Materials that transition to the deconsolidative-convective burn mechanism at elevated pressures have been shown to be considerably more violent in confined heating experiments (i.e. cook-off scenarios). The mechanisms of propellant and explosive deflagration are extremely complex and include both chemical, and mechanical processes, hence predicting the behavior and rate of a novel material or formulation is difficult if not impossible. In this work, the AP/HTPB based material, TAL-1503 (B-2049), was burned in a constant volume apparatus in argon up to 300 MPa (ca. 44 kPSI). The burn rate and pressure were measured in-situ and used to calculate a pressure dependent burn rate. In general, the material appears to burn in a laminar fashion at these elevated pressures. The experiment was reproduced multiple times and the burn rate law using the best data is B = (0.6 {+-} 0.1) x P{sup (1.05{+-}0.02)} where B is the burn rate in mm/s and P is the pressure in units of MPa. Details of the experimental method, results and data analysis are discussed herein and briefly compared to other AP based materials that have been measured in this apparatus.

Method and apparatus to measure the depth of skin burns  

DOE Patents [OSTI]

A new device for measuring the depth of surface tissue burns based on the rate at which the skin temperature responds to a sudden differential temperature stimulus. This technique can be performed without physical contact with the burned tissue. In one implementation, time-dependent surface temperature data is taken from subsequent frames of a video signal from an infrared-sensitive video camera. When a thermal transient is created, e.g., by turning off a heat lamp directed at the skin surface, the following time-dependent surface temperature data can be used to determine the skin burn depth. Imaging and non-imaging versions of this device can be implemented, thereby enabling laboratory-quality skin burn depth imagers for hospitals as well as hand-held skin burn depth sensors the size of a small pocket flashlight for field use and triage.

Long-term monitoring of microleakage of dental cements by radiochemical diffusion  

SciTech Connect (OSTI)

Radioactive /sup 14/C sucrose was found to be an ideal marker for microleakage because it did not penetrate tooth tissue, dental cement, or mounting resin. The main finding is that the adhesive cements--the glass-ionomer and polycarboxylate--are significantly more effective at preventing microleakage than are the traditional phosphate cements--silicate and zinc phosphate. The differences can be as high as two orders of magnitude. The adhesive cements provide almost perfect and reliable seals. By contrast, the nonadhesive cements are erratic sealants with most of the restorations leaking.
