Development of a Coal Quality Expert  

SciTech Connect

ABB Power Plant Laboratories Combustion Engineering, Inc., (ABB CE) and CQ Inc. completed a broad, comprehensive program to demonstrate the economic and environmental benefits of using higher quality U.S. coals for electrical power generation and developed state-of-the-art user-friendly software--Coal Quality Expert (CQE)-to reliably predict/estimate these benefits in a consistent manner. The program was an essential extension and integration of R and D projects performed in the past under U.S. DOE and EPRI sponsorship and it expanded the available database of coal quality and power plant performance information. This software will permit utilities to purchase the lowest cost clean coals tailored to their specific requirements. Based on common interest and mutual benefit, the subject program was cosponsored by the U.S. DOE, EPRI, and eight U.S. coal-burning utilities. In addition to cosponsoring this program, EPN contributed its background research, data, and computer models, and managed some other supporting contracts under the terms of a project agreement established between CQ Inc. and EPRI. The essential work of the proposed project was performed under separate contracts to CQ Inc. by Electric Power Technologies (El?'T), Black and Veatch (B and V), ABB Combustion Engineering, Babcock and Wilcox (B and W), and Decision Focus, Inc. Although a significant quantity of the coals tied in the United States are now cleaned to some degree before firing, for many of these coals the residual sulfur content requires users to install expensive sulfur removal systems and the residual ash causes boilers to operate inefficiently and to require frequent maintenance. Disposal of the large quantities of slag and ash at utility plant sites can also be problematic and expensive. Improved and advanced coal cleaning processes can reduce the sulfur content of many coals to levels conforming to environmental standards without requiring post-combustion desulfurization systems. Also, some coals may be beneficiated or blended to a quality level where significantly less costly desulfurization systems are needed. Coal cleaning processes may also be used to remove the precursors of other troublesome emissions that can be identified now or in the future. An added benefit of coal cleaning and blending is the reduction in concentrations of mineral impurities in the fuel leading to improved performance and operation of the'' boiler in which it is fired. The ash removed during the pre-combustion cleaning process can be more easily and safely disposed of at the mine than at the utility plant after combustion. EPRI's Coal Quality Impact Model (CQIM) has shown that improved fuel quality can result in savings in unit capital and operating costs. This project produced new and improved software to select coal types and specifications resulting in the best quality and lowest cost fuel to meet specific environmental requirements.

Coal quality and estimated coal resources in the proposed Colville Mining District, central North Slope, Alaska  

SciTech Connect

The proposed Colville Mining District (CMD) encompasses 27,340 mi{sup 2} (70,800 km{sup 2}) in the central part of the North Slope. Known coal deposits within the proposed district range from Mississippian to Tertiary in age. Available information indicates that neither Mississippian and Tertiary coals in the CMD constitute a significant resource because they are excessively deep, thin, or high in ash content; however, considerable amount of low-sulfur Cretaceous coal is present. The paper briefly describes the geology and quality of these coal reserves. Difficult conditions will restrict mining of these coals in the near future.

The relationship between coal quality and coal resource parameters of Powder River and Williston Basin coal, Wyoming, Montana, and North Dakota  

SciTech Connect

Clean, compliant coal from mines in the Northern Rocky Mountain and Great Plains region is utilized as fuel for coal-fired power plants in 26 states. More than 30 percent of the nation`s 1997 production was from Montana, North Dakota, and Wyoming. Production of clean, compliant coal from the region is estimated to increase to 415 million short tons by the year 2015. Studies in this region indicate a relationship between percent sulfur and ash and pounds of SO{sub 2} per million Btu and the resource parameters of coal thickness and overburden. The trends that the authors have observed indicate that both coal quality and the thickness of the coal and associated rocks are controlled by paleoenvironment and depositional setting.

Express quality analysis of coal concentrates by diffuse reflection IR spectroscopy  

SciTech Connect

Ongoing quality monitoring of coal concentrates is important today on account of instability in the raw materials for coking at OAO Magnitogorskii Metallurgicheskii Kombinat (MMK) and the variable composition of the coal batch for enrichment plants. Currently, numerous standardized methods permit the determination of the classificational and quality characteristics of coal and batch. These methods are slow, laborious, and relatively ineffective in industrial conditions. In May 2005, an automated Spektrotest express-analysis system developed by ECCI was installed in the coke laboratory at ZAO RMK in order to determine the quality of the coal concentrate and batch. The basic equipment is an IR spectrometer with a unit for Fourier transformation and a special optical module yielding the reflect on spectra of the pulverized coal. A control station based on a high-speed computer runs an algorithm for information analysis and storage and for printing out the test protocol. The Spektrotest system includes complex algorithms and software specially developed at ECCI.

Effects of paleolatitude on coal quality - model for organic sulfur distribution in US coal  

SciTech Connect

In the conterminous US, most Carboniferous peats accumulated at latitudes of 0/degrees/-15/degrees/S, Cretaceous Rocky Mountain province peats at 30/degrees/-45/degrees/N, Tertiary northern Great Plains peats at 40/degrees/-55/degrees/N, and Tertiary Gulf Coast peats at 30/degrees/-40/degrees/N. Alaskan Cretaceous and Tertiary peats accumulated at latitudes above 70/degrees/N. A comparison of paleolatitudes calculated from paleomagnetic poles and organic sulfur contents for more than 7000 coal samples indicates that the higher the latitude in which a peat swamp developed, the lower the mean organic sulfur content of the subsequent coal (correlation coefficient - 0.4; significant at the 99% confidence level). Mean organic sulfur contents range from 0.90% (range = 0.01-5.08%, standard deviation = 0.56) in low-latitude Carboniferous coal to 0.25% (range = 0.01-1.41%, standard deviation = 0.23) in high-latitude Alaskan Cretaceous and Tertiary coal.

JV TASK - PREDICTIVE COAL QUALITY EFFECTS SCREENING TOOL (PCQUEST)  

SciTech Connect

PCQUEST, a package of eight predictive indices, was developed with U.S. Department of Energy (DOE) support by the Energy and Environmental Research Center to predict fireside performance in coal-fired utility boilers more reliably than traditional indices. Since the development of PCQUEST, the need has arisen for additional fuel types into the program database. PCQUEST was developed using combustion inorganic transformation theory from previous projects and from empirical data derived from laboratory experiments and coal boiler field observations. The goal of this joint venture project between commercial industry clients and DOE is to further enhance PCQUEST and improve its utility for a variety of new fuels and systems. Specific objectives include initiating joint venture projects with utilities, boiler vendors, and coal companies that involve real-world situations and needs in order to strategically improve algorithms and input-output functions of PCQUEST, as well as to provide technology transfer to the industrial sector. The main body of this report provides a short summary of the projects that were closed from February 1999 through June 2006. All of the reports sent to the commercial clients can be found in the appendix.

Effect of Indian Medium Coking Coal on Coke Quality in Non-recovery Stamp Charged Coke Oven  

Science Journals Connector (OSTI)

Abstract The maximum possibility of utilizing the Indian coking coals and inferior grade coking coal for producing metallurgical coke through non-recovery stamp charging technology was investigated. Indian indigenous coals contained low percent of vitrinite ( 15%) compared to imported coking coal. Therefore, the selection of appropriate proportion of different types of coals was a major challenge for coke makers. Coal blend selection criterion based on a single coefficient, named as composite coking potential (CCP), was developed. The use of increased proportion of semi-soft coal (crucible swelling number of 2.5) and high ash (? 15%) indigenous coal in the range of 20%–35% and 20%–65% respectively in the blends resulted in good quality of coke. Plant data of a non-recovery coke oven were used for developing and validating the model. The results showed that the coke strength after reaction (CSR) varied in the range of 63. 7%–67.7% and the M40 value was between 81.8 and 89.3 in both the cases.

Injection began at the test site on June 15; the site was selected because it is representative of the 23,000- square-mile Black Warrior Basin located in northwestern Alabama and northeastern Mississippi. It is estimated that this area has the potential to store in the range of 1.1 to 2.3 Gigatons of CO 2 , which is approximately the amount that Alabama's coal-fired power plants emit in two decades. The targeted coal seams range from 940 to 1,800 feet deep and are one to six feet thick. Approximately 240 tons of CO 2 will be injected over a 45- to 60-day period. More information

The role of combustion diagnostics in coal quality impact and NO{sub x} emissions field test programs  

SciTech Connect

Many utilities are examining low sulfur coal or coal blending options to comply with the Clean Air Act Amendment SO{sub 2} emission limits. Test burns have been conducted with the more promising candidate coals to characterize the potential impact of a change in coal quality on boiler operation and performance. Utilities are also under considerable pressure to evaluate NO{sub x} control options and develop a compliance plan to meet strict NO{sub x} regulations, particularly in high population density metropolitan areas on the Eastern seaboard. Field test programs have been conducted to characterize baseline NO{sub x} emissions, evaluate the NO{sub x} reduction potential of combustion modifications, and assess the potential of combustion tuning as an alternative to burner replacement. Coal quality impacts (slagging, fouling, heat absorption, ash removal) and NO{sub x} emissions are both strongly dependent upon the coal combustion process and site-specific boiler firing practices. Non-uniform combustion in the burner region can result in adverse ash deposition characteristics, carbon carryover problems, high furnace exit gas temperatures, and NO{sub x}emission characteristics that are not representative of the coal or the combustion equipment. Advanced combustion diagnostic test procedures have been developed to evaluate and improve burner zone combustion uniformity, even in cases where the coal flow to the individual burners may be non-uniform. The paper outlines a very practical solving approach to identifying combustion related problems that affect ash deposition and NO{sub x} emissions. The benefits of using advanced diagnostic instrumentation to identify problems and tune combustion conditions is illustrated using test data from recent quality field test programs.

Coal preparation: The essential clean coal technology  

SciTech Connect

This chapter is a brief introduction to a broad topic which has many highly specialized areas. The aim is to summarize the essential elements of coal preparation and illustrate its important role in facilitating the clean use of coal. Conventional coal preparation is the essential first step in ensuring the economic and environmentally acceptable use of coal. The aim of coal preparation is to produce saleable products of consistent, specified quality which satisfy customer requirements while optimizing the utilization of the coal resource. Coal preparation covers all aspects of preparing coal for the market. It includes size reduction, blending and homogenization and, most importantly, the process of physical beneficiation or washing, which involves separation of undesirable mineral matter from the coal substance itself. Coal preparation can be performed at different levels of sophistication and cost. The degree of coal preparation required is decided by considering the quality of the raw coal, transport costs and, in particular, the coal quality specified by the consumer. However, the cost of coal beneficiation rises rapidly with the complexity of the process and some coal is lost with the waste matter because of process inefficiencies, therefore each situation requires individual study to determine the optimum coal preparation strategy. The necessary expertise is available within APEC countries such as Australia. Coals destined for iron making are almost always highly beneficiated. Physical beneficiation is mostly confined to the higher rank, hard coals, but all other aspects of coal preparation can be applied to subbituminous and lignitic coals to improve their utilization. Also, there are some interesting developments aimed specifically at reducing the water content of lower rank coals.

Coal industry annual 1993  

SciTech Connect

Coal Industry Annual 1993 replaces the publication Coal Production (DOE/FIA-0125). This report presents additional tables and expanded versions of tables previously presented in Coal Production, including production, number of mines, Productivity, employment, productive capacity, and recoverable reserves. This report also presents data on coal consumption, coal distribution, coal stocks, coal prices, coal quality, and emissions for a wide audience including the Congress, Federal and State agencies, the coal industry, and the general public. In addition, Appendix A contains a compilation of coal statistics for the major coal-producing States. This report does not include coal consumption data for nonutility Power Producers who are not in the manufacturing, agriculture, mining, construction, or commercial sectors. This consumption is estimated to be 5 million short tons in 1993.

Relationship between coking coal quality and its micro-Raman spectral characteristics  

Science Journals Connector (OSTI)

Abstract Micro-Raman spectroscopy examination of 20 samples of coking coals (Rr = 0.84–1.43%) was performed. Spectral parameters were correlated with the basic rank and technological properties of coals. The G band FWHM and the AG/AALL ratio decrease with the volatile matter content (Vdaf) decrease and the all maceral reflectance scan (Rscan) value increase. The correlations between these parameters are stronger than those, between the G band FWHM and the AG/AALL ratio, and the mean random vitrinite reflectance (Rr). Coking properties are weakly related to the Raman spectral characteristics of coal. Based on the Raman parameters G band FWHM and the AG/AALL ratio, it may be possible to evaluate the volatile matter content (Vdaf) and the all maceral reflectance scan (Rscan) value for coking coals.

Rationale for continuing R&D in direct coal conversion to produce high quality transportation fuels  

SciTech Connect

For the foreseeable future, liquid hydrocarbon fuels will play a significant role in the transportation sector of both the United States and the world. Factors favoring these fuels include convenience, high energy density, and the vast existing infrastructure for their production and use. At present the U.S. consumes about 26% of the world supply of petroleum, but this situation is expected to change because of declining domestic production and increasing competition for imports from countries with developing economies. A scenario and time frame are developed in which declining world resources will generate a shortfall in petroleum supply that can be allieviated in part by utilizing the abundant domestic coal resource base. One option is direct coal conversion to liquid transportation fuels. Continued R&D in coal conversion technology will results in improved technical readiness that can significantly reduce costs so that synfuels can compete economically in a time frame to address the shortfall.

The Public Subsidies of Coal  

Science Journals Connector (OSTI)

I have spent most of my life in western Pennsylvania, in the Appalachian coal belt of the U.S. I have direct experience with the economic, environmental, and social impacts of coal extraction and use. ... Although coal was important in building the economy of western Pennsylvania as well as the economies of other coal regions, its extraction and use left a legacy of damage: thousands of miles of streams severely impacted by acid drainage from abandoned mines; large piles of coal mine refuse; old strip mines that have not been refilled; damaged groundwater resources; and land subsidence from underground mining. ...

Stable isotope and water quality analysis of coal bed methane production waters and gases from the Bowen Basin, Australia  

Science Journals Connector (OSTI)

Coal bed methane (CBM) is a significant growing industry in Queensland's energy sector. It is, however, a relatively new industry with little local water quality data and stable isotope compositions of production waters and gases available in the public domain. This study aims to determine whether water quality and stable isotope data can be correlated with gas and groundwater production and flow pathways, and identify zones of recharge and water mixing. Stable isotope analysis and accessory water quality tests were conducted on CBM production gas and water samples collected from two CBM producing bituminous coal seams within a single field in the Bowen Basin. In the production field, the reservoir seams are gently folded with eastwardly dipping fold axes, and compartmentalised by an ENE normal fault on the flank of a broad central anticline that contains minor faults. For one seam, splitting and a change in coal quality parallels the fault and fold axes. Although virgin reservoir conditions were similar, differing production performance north and south of the main fault suggests it acts as a barrier to water and gas flow along strike. The stable isotope analysis on the production water showed that waters with more positive ?D and ?18O compositions were associated with areas of higher water production and shallower depths, whereas more negative ?D and ?18O compositions were associated with lower water production and high gas production. The gas isotope analysis showed that production gases had both biogenic and thermogenic origins and that secondary biogenic gas generated through CO2 reduction comprises a significant portion of the CBM produced from this field. More negative CH4 ?13C values characterize the zones of meteoric recharge in shallow, up-dip areas. Gas production data and CO2 ?13C values suggest that this may result from 13CH4 stripping by the recharge waters and/or increased biogenic activity in this area. Smaller CO2–CH4 carbon isotopic fractionation values characterized zones of meteoric recharge, whereas higher isotopic fractionation values characterized the high gas production domain.

Coal occurrence, quality and resource assessment, National Petroleum Reserve in Alaska  

SciTech Connect

Field studies of the Cretaceous Torok, Kukpowruk, and Corwin Formations in the western portion of the NPRA (National Petroleum Reserve in Alaska) and Cretaceos Torok, Tuktu, Grandstand, and Chandler Formations in the eastern portion of NPRA indicate that two major delta systems are responsible for most of the coal accumulation in this area. The Corwin delta in the western portion was an early Albian to Cenomanian, north and east prograding system, whereas the slightly younger mid-Albian to Cenomanian Umiat delta system prograded north and northeast in the eastern portion. Investigations of the lightologies, fossils, and primary depositional structures of these formations indicate that the Corwin system was deposited as a large, high-constructional, shaped delta on which thick and numerous coals developed on splay and interdistributary bay platforms away from the influence of the Cretaceous epicontinental sea. The Umiat delta started out as a high-constructional system but in time became wave dominated, and its shape changed to lobate.

Assessing the cumulative impacts of surface mining and coal bed methane development on shallow aquifers in the Powder River Basin, Wyoming  

SciTech Connect

Large scale surface coal mining taken place along the cropline of the Wyodak-Anderson coal seam since approximately 1977. Groundwater impacts due to surface mining of coal and other energy-related development is a primary regulatory concern and an identified Office of Surface Mining deficiency in the Wyoming coal program. The modeled aquifers are the upper unit (coal) of the Paleocene Fort Union Formation and the overlying Eocene Wasatch Formation. A regional groundwater model covering 790 square miles was constructed using MODFLOW, to simulate the impacts from three surface coal mines and coal bed methane development occurring downdip. Assessing anisotropy of the coal aquifer, quality checking of in situ aquifer tests and database quality control were precursors to modelling. Geologic data was kriged to develop the structural model of the aquifers. A Geographic Information System (GIS) was utilized to facilitate storage, analysis, display, development of input modelling arrays and assessment of hydrologic boundaries. Model output presents the predicted impacts of likely development scenarios, including impacts from coal bed methane development and surface coal mining through anticipated life of mining, and surface mining impacts independent of gas development.

Design of a laser-induced breakdown spectroscopy system for on-line quality analysis of pulverized coal in power plants  

SciTech Connect

It is vitally important for a power plant to determine the chemical composition of coal prior to combustion in order to obtain optimal boiler control. In this work, a fully software-controlled laser-induced breakdown spectroscopy (LIBS) system comprising a LIBS apparatus and sampling equipment has been designed for possible application to power plants for on-line quality analysis of pulverized coal. Special attention was given to the LIBS system, the data processing methods (especially the normalization with Bode Rule/DC Level) and the specific settings (the software-controlled triggering source, high-pressure gas cleaning device, sample preparation module, sampling module, etc.), which gave the best direct measurement for C, H, Si, Na, Mg, Fe, Al, and Ti with measurement errors less than 10% for pulverized coal. Therefore, the apparatus is accurate enough to be applied to industries for on-line monitoring of pulverized coal. The method of proximate analysis was also introduced and the experimental error of A(ad) (Ash, 'ad' is an abbreviation for 'air dried') was shown in the range of 2.29 to 13.47%. The programmable logic controller (PLC) controlled on-line coal sampling equipment, which is designed based upon aerodynamics, and is capable of performing multipoint sampling and sample-preparation operation.

Forward and reverse combustion gasification of coal with production of high-quality syngas in a simulated pilot system for in situ gasification  

Science Journals Connector (OSTI)

Abstract This research focused on the feasibility and stability of applying the forward and reverse combustion approach to the in situ gasification of lignite and bituminous coal with oxygen or oxygen–steam mixtures as gasification agents, especially reverse combustion gasification. A high-quality syngas (H2 and CO) could be obtained using the reverse combustion gasification technique combined with forward combustion gasification in a pilot system for in situ gasification. The gasification time was extended more than 25% using the reverse combustion approach. The controlling conditions for reverse combustion gasification were obtained by comparing and analyzing experimental data. The results show the relationship between the inject gas flow within certain limits and velocity of the gasification flame was linear during reverse combustion. The underground conditions of the coal seam and strata were simulated in a pilot-scale underground gasifier during experiments. The combustion gasification of coal was carried out experimentally for over 5 days. The average effective content (H2 and CO) of syngas was in the range of 60–70%, meeting the requirement of synthesis gas. The optimal ranges of gasifying lignite and bituminous coal were found to be 1.5–2.0 and 1.3–1.75, respectively. The product gas flow was proportional to oxygen blast. These are expected to provide useful guidance on practical underground coal gasification operations and to give experimental evidence in support of theory.

3. Vehicle-Miles Traveled 3. Vehicle-Miles Traveled Chapter 3. Vehicle-Miles Traveled Vehicle-miles traveled--the number of miles that residential vehicles are driven--is probably the most important information collected by the Residential Transportation Energy Consumption Survey. Using the data on vehicle-miles traveled allows analysts to answer such questions as: "Are minivans driven more than passenger cars?" "Do people in the West drive more than people elsewhere?" "Do people conserve their new cars by driving them less?" "Who drives more--people in households with children, or other people?" "At what ages do people drive the most?" "How does growing income affect the amount of driving?" In addition to answering those kinds of questions, analysts also use the number of vehicle-miles traveled to compute estimated, on-road vehicle fuel consumption, economy, and expenditures, all of which have important implications for U.S. energy policy and national security (see Chapter 4).

Investigations into coal coprocessing and coal liquefaction  

SciTech Connect

The conversion of coal to liquid suitable as feedstock to a petroleum refinery is dependent upon several process variables. These variables include temperature, pressure, coal rank, catalyst type, nature of the feed to the reactor, type of process, etc. Western Research Institute (WRI) has initiated a research program in the area of coal liquefaction to address the impact of some of these variables upon the yield and quality of the coal-derived liquid. The principal goal of this research is to improve the efficiency of the coal liquefaction process. Two different approaches are currently being investigated. These include the coprocessing of a heavy liquid, such as crude oil, and coal using a dispersed catalyst and the direct liquefaction of coal using a supported catalyst. Another important consideration in coal liquefaction is the utilization of hydrogen, including both externally- and internally-supplied hydrogen. Because the incorporation of externally-supplied hydrogen during conversion of this very aromatic fossil fuel to, for example, transportation fuels is very expensive, improved utilization of internally-supplied hydrogen can lead to reducing processing costs. The objectives of this investigation, which is Task 3.3.4, Coal Coprocessing, of the 1991--1992 Annual Research Plan, are: (1) to evaluate coal/oil pretreatment conditions that are expected to improve the liquid yield through more efficient dispersion of an oil-soluble, iron-based catalyst, (2) to characterize the coke deposits on novel, supported catalysts after coal liquefaction experiments and to correlate the carbon skeletal structure parameters of the coke deposit with catalyst performance as measured by coal liquefaction product yield, and (3) to determine the modes of hydrogen utilization during coal liquefaction and coprocessing. Experimental results are discussed in this report.

COAL LOGISTICS. Tracking U.S. Coal Exports  

SciTech Connect

COAL LOGISTICS has the capability to track coal from a U. S. mine or mining area to a foreign consumer`s receiving dock. The system contains substantial quantities of information about the types of coal available in different U. S. coalfields, present and potential inland transportation routes to tidewater piers, and shipping routes to and port capabilities in Italy, Japan, South Korea, Taiwan, and Thailand. It is designed to facilitate comparisons of coal quality and price at several stages of the export process, including delivered prices at a wide range of destinations. COAL LOGISTICS can be used to examine coal quality within or between any of 18 U. S. coalfields, including three in Alaska, or to compare alternative routes and associated service prices between coal-producing regions and ports-of-exit. It may be used to explore the possibilities of different ship sizes, marine routes, and foreign receiving terminals for coal exports. The system contains three types of information: records of coal quality, domestic coal transportation options, and descriptions of marine shipment routes. COAL LOGISTICS contains over 3100 proximate analyses of U. S. steam coals, usually supplemented by data for ash softening temperature and Hardgrove grindability; over 1100 proximate analyses for coals with metallurgical potential, usually including free swelling index values; 87 domestic coal transportation options: rail, barge, truck, and multi-mode routes that connect 18 coal regions with 15 U. S. ports and two Canadian terminals; and data on 22 Italian receiving ports for thermal and metallurgical coal and 24 coal receiving ports along the Asian Pacific Rim. An auxiliary program, CLINDEX, is included which is used to index the database files.

Dry cleaning of Turkish coal  

SciTech Connect

This study dealt with the upgrading of two different type of Turkish coal by a dry cleaning method using a modified air table. The industrial size air table used in this study is a device for removing stones from agricultural products. This study investigates the technical and economical feasibility of the dry cleaning method which has never been applied before on coals in Turkey. The application of a dry cleaning method on Turkish coals designated for power generation without generating environmental pollution and ensuring a stable coal quality are the main objectives of this study. The size fractions of 5-8, 3-5, and 1-3 mm of the investigated coals were used in the upgrading experiments. Satisfactory results were achieved with coal from the Soma region, whereas the upgrading results of Hsamlar coal were objectionable for the coarser size fractions. However, acceptable results were obtained for the size fraction 1-3 mm of Hsamlar coal.

Coal cleaning program for Kazakstan  

SciTech Connect

In 1992 the United States Agency for International Development (USAID) started sponsoring general projects in the Energy and Environmental Sector to improve health and well-being, to improve the efficiency of the existing fuel and energy base, and to assist in the establishment of a strong private sector. Coal Cleaning Program, covered in this report, is one of the recently completed projects by Burns and Roe, which is a prime USAID contractor in the field of energy and environment for the NIS. The basis for coal cleaning program is that large coal resources exist in northeast Kazakstan and coal represents the major fuel for heat and electricity generation at present and in the foreseeable future. The coal mined at Karaganda and Ekibastuz, the two main coal mining areas of Kazakstan, currently contains up to 55% ash, whereas most boilers in Kazakstan are designed to fire a coal with an ash content no greater than 36%. The objective of the task was to determine optimum, state-of-the-art coal cleaning and mining processes which are applicable to coals in Kazakstan considering ultimate coal quality of 36% ash, environmental quality, safety and favorable economics.

Three Mile Island: the financial fallout  

SciTech Connect

The nuclear accident at Three Mile Island raised serious questions about the financial ability of the electric utility company owners to clean up and repair the damaged reactor facilities while continuing to provide reliable electric service to customers. Financial insolvency of the companies is not imminent and power supplies are assured for the immediate future. However, the loss of earnings capability by the Metropolitan Edison Company makes it questionable whether it can fund its share of the clean-up costs and maintain system reliability without large rate increases or some external financial assistance. The accident has shown that the utilities and Federal and State regulatory agencies were not prepared to deal with recovery from such a large financial loss. The Department of Energy should move swiftly to assess the financial needs of the affected utilities and develop plans for meeting them.

Three Mile Island: meltdown of democracy  

SciTech Connect

Strong local opposition to a start-up of Unit 1 at Three Mile Island continues because citizen distrust of General Public Utilities was found in post-accident studies to have been justified. Several citizen groups have monitored the Unit 2 clean-up activities and have not been reassured by either the President's Commission or the Nuclear Regulatory Commission. Efforts to improve public relations by distributing radiation kits or other strategies have been outweighed by evidence of government manipulation of early bomb test data and poor industry planning. Arguments over who is responsible for the accident and who is liable for the cost have further undermined credibility. Area residents have received three recent legal signals that their position may prevail. (DCK)

Coal surface control for advanced fine coal flotation  

SciTech Connect

The initial goal of the research project was to develop methods of coal surface control in advanced froth flotation to achieve 90% pyritic sulfur rejection, while operating at Btu recoveries above 90% based on run-of-mine quality coal. Moreover, the technology is to concomitantly reduce the ash content significantly (to six percent or less) to provide a high-quality fuel to the boiler (ash removal also increases Btu content, which in turn decreases a coal's emission potential in terms of lbs SO{sub 2}/million Btu).

Debate over waste imperils 3-Mile cleanup  

SciTech Connect

The cleanup is a task of extraordinary proportions. Every step in the cleanup must be taken in a highly sensitive political and regulatory environment. A demineralizer or ion exchange filtration unit was installed in order that the fission products could be removed from the water spilled in the auxiliary and fuel handling buildings. GPU later vented krypton gas. Twice now engineers have made cautions entries into the containment building as part of the effort to size up the job. Cleanup will be costly, requiring many workers. Some wastes will require special packaging in hundreds of containers with shielded overpacks, plus bulky items of hardware and equipment that cannot be easily packaged. There will be the damaged fuel assemblies from the reactor core. Removing the fuel from the reactor may be difficult. A troublesome waste disposal question has to do with the material to be generated in cleaning up the containment building's sump water. GPU's man in charge of clean-up strategy is to collect the wastes in a form that permits maximum flexibility with respect to their stage, packaging, transport, and ultimate disposal. If plans for disposal of all the wastes from the cleanup are to be completed, an early commitment by Pennsylvania and other northeastern states to establish a burial ground for low level waste generated within the region is needed. Also a speedy commitment by NRC, DOE, and Congress to a plan for disposal of the first-stage zeolites is needed. Should there be a failure to cope with the wastes that Three Mile Island cleanup generates, the whole nuclear enterprise may suffer.

China's Coal: Demand, Constraints, and Externalities  

SciTech Connect

This study analyzes China's coal industry by focusing on four related areas. First, data are reviewed to identify the major drivers of historical and future coal demand. Second, resource constraints and transport bottlenecks are analyzed to evaluate demand and growth scenarios. The third area assesses the physical requirements of substituting coal demand growth with other primary energy forms. Finally, the study examines the carbon- and environmental implications of China's past and future coal consumption. There are three sections that address these areas by identifying particular characteristics of China's coal industry, quantifying factors driving demand, and analyzing supply scenarios: (1) reviews the range of Chinese and international estimates of remaining coal reserves and resources as well as key characteristics of China's coal industry including historical production, resource requirements, and prices; (2) quantifies the largest drivers of coal usage to produce a bottom-up reference projection of 2025 coal demand; and (3) analyzes coal supply constraints, substitution options, and environmental externalities. Finally, the last section presents conclusions on the role of coal in China's ongoing energy and economic development. China has been, is, and will continue to be a coal-powered economy. In 2007 Chinese coal production contained more energy than total Middle Eastern oil production. The rapid growth of coal demand after 2001 created supply strains and bottlenecks that raise questions about sustainability. Urbanization, heavy industrial growth, and increasing per-capita income are the primary interrelated drivers of rising coal usage. In 2007, the power sector, iron and steel, and cement production accounted for 66% of coal consumption. Power generation is becoming more efficient, but even extensive roll-out of the highest efficiency units would save only 14% of projected 2025 coal demand for the power sector. A new wedge of future coal consumption is likely to come from the burgeoning coal-liquefaction and chemicals industries. If coal to chemicals capacity reaches 70 million tonnes and coal-to-liquids capacity reaches 60 million tonnes, coal feedstock requirements would add an additional 450 million tonnes by 2025. Even with more efficient growth among these drivers, China's annual coal demand is expected to reach 3.9 to 4.3 billion tonnes by 2025. Central government support for nuclear and renewable energy has not reversed China's growing dependence on coal for primary energy. Substitution is a matter of scale: offsetting one year of recent coal demand growth of 200 million tonnes would require 107 billion cubic meters of natural gas (compared to 2007 growth of 13 BCM), 48 GW of nuclear (compared to 2007 growth of 2 GW), or 86 GW of hydropower capacity (compared to 2007 growth of 16 GW). Ongoing dependence on coal reduces China's ability to mitigate carbon dioxide emissions growth. If coal demand remains on a high growth path, carbon dioxide emissions from coal combustion alone would exceed total US energy-related carbon emissions by 2010. Within China's coal-dominated energy system, domestic transportation has emerged as the largest bottleneck for coal industry growth and is likely to remain a constraint to further expansion. China has a low proportion of high-quality reserves, but is producing its best coal first. Declining quality will further strain production and transport capacity. Furthermore, transporting coal to users has overloaded the train system and dramatically increased truck use, raising transportation oil demand. Growing international imports have helped to offset domestic transport bottlenecks. In the long term, import demand is likely to exceed 200 million tonnes by 2025, significantly impacting regional markets.

Conventional coal preparation in the United States  

SciTech Connect

Processing of bituminous and anthracite coal is widely practiced in the United States and, as mentioned earlier, about 80 percent of the production of these coals is processed as clean coal in preparation plants. Subbituminous coal is not widely processed, primarily because these low rank raw coals are low in sulfur (0.5 to 1.0 percent) and relatively low in ash (8 to 15 percent). They are also relatively low in heat content due to their high inherent moisture. Lignite coals, to the best of the authors{close_quote} knowledge, are not presently being processed in Conventional Coal Preparation plants. This is due to their unstable nature and putting them in water in a coal preparation plant is likely to cause severe degradation in particle size and add to their already high inherent moisture content. The following are the benefits of clean coal processing: produces a uniform product which can be utilized more efficiently; produces a higher quality product which results in higher efficiency at the power station or the steel mill; reduces sulfur dioxide and other adverse stack emissions during coal firing which is a very important environmental consideration; reduces ash or slag handling costs by the user; reduces shipping costs; and reduces handling and storage costs. Processing any stable raw coal in a coal preparation plant will always produce a higher grade product which is a more efficient and a more environmentally acceptable fuel for use at power stations, steel mills, home heating or industrial boilers.

1 - Social and economic value of coal  

Science Journals Connector (OSTI)

Abstract: As the world’s leading source of electric power, coal is the continuing cornerstone of economic development, social progress, and a higher quality of life. Coal is powering the twenty-first century economic miracles rapidly unfolding in China and India, as reliability, affordability, and availability make coal the fuel of choice in the developing world. Demand modeling from both the International Energy Agency and US Energy Information Administration indicates that coal will provide the most amount of incremental energy over the next two decades. Looking forward, with the expanding implementation of clean coal technologies, the door to coal’s global leadership role will remain open as the world strives to meet the ever-rising demand for energy while reducing greenhouse gas emissions.

The challenges at the La Robla I Station stem from the various fuels used, the characteristics of which differ from the design coal. The University of North Dakota Energy & Environmental Research Center (EERC) and the Lehigh University Energy Research Center (LUERC) undertook a program to assess problematic slagging and unburned carbon issues occurring at the plant. Full-scale combustion tests were performed under baseline conditions, with elevated oxygen level and with redistribution of air during a site visit at the plant. During these tests, operating information, observations and temperature measurements, and coal, slag deposit, and fly ash samples were obtained to assess slagging and unburned carbon. The slagging in almost all cases appeared due to elevated temperatures rather than fuel chemistry. The most severe slagging occurred when the temperature at the sampling port was in excess of 1500 C, with problematic slagging where first-observed temperatures exceeded 1350 C. The presence of anorthite crystals in the bulk of the deposits analyzed indicates that the temperatures were in excess of 1350 C, consistent with temperature measurements during the sampling period. Elevated temperatures and ''hot spots'' are probably the result of poor mill performance, and a poor distribution of the coal from the mills to the specific burners causes elevated temperatures in the regions where the slag samples were extracted. A contributing cause appeared to be poor combustion air mixing and heating, resulting in oxygen stratification and increased temperatures in certain areas. Air preheater plugging was observed and reduces the temperature of the air in the windbox, which leads to poor combustion conditions, resulting in unburned carbon as well as slagging. A second phase of the project involved advanced analysis of the baseline coal along with an Australian coal fired at the plant. These analysis results were used in equilibrium thermodynamic modeling along with a coal quality model developed by the EERC to assess slagging, fouling, and opacity for the coals. Bench-scale carbon conversion testing was performed in a drop-tube furnace to assess the reactivity of the coals. The Australian coal had a higher mineral content with significantly more clay minerals present than the baseline coal. The presence of these clay minerals, which tend to melt at relatively low temperatures, indicated a higher potential for problematic slagging than the baseline coal. However, the pyritic minerals, comprising over 25% of the baseline mineral content, may form sticky iron sulfides, leading to severe slagging in the burner region if local areas with reducing conditions exist. Modeling results indicated that neither would present significant fouling problems. The Australian coal was expected to show slagging behavior much more severe than the baseline coal except at very high furnace temperatures. However, the baseline coal was predicted to exhibit opacity problems, as well as have a higher potential for problematic calcium sulfate-based low-temperature fouling. The baseline coal had a somewhat higher reactivity than the Australian coal, which was consistent with both the lower average activation energy for the baseline coal and the greater carbon conversion at a given temperature and residence time. The activation energy of the baseline coal showed some effect of oxygen on the activation energy, with E{sub a} increasing at the lower oxygen concentration, but may be due to the scatter in the baseline coal kinetic values at the higher oxygen level tested.

Coal surface control for advanced fine coal flotation. Final report, October 1, 1988--March 31, 1992  

SciTech Connect

The initial goal of the research project was to develop methods of coal surface control in advanced froth flotation to achieve 90% pyritic sulfur rejection, while operating at Btu recoveries above 90% based on run-of-mine quality coal. Moreover, the technology is to concomitantly reduce the ash content significantly (to six percent or less) to provide a high-quality fuel to the boiler (ash removal also increases Btu content, which in turn decreases a coal`s emission potential in terms of lbs SO{sub 2}/million Btu).

Opportunities for coal to methanol conversion  

SciTech Connect

The accumulations of mining residues in the anthracite coal regions of Pennsylvania offer a unique opportunity to convert the coal content into methanol that could be utilized in that area as an alternative to gasoline or to extend the supplies through blending. Additional demand may develop through the requirements of public utility gas turbines located in that region. The cost to run this refuse through coal preparation plants may result in a clean coal at about $17.00 per ton. After gasification and synthesis in a 5000 ton per day facility, a cost of methanol of approximately $3.84 per million Btu is obtained using utility financing. If the coal is to be brought in by truck or rail from a distance of approximately 60 miles, the cost of methanol would range between $4.64 and $5.50 per million Btu depending upon the mode of transportation. The distribution costs to move the methanol from the synthesis plant to the pump could add, at a minimum, $2.36 per million Btu to the cost. In total, the delivered cost at the pump for methanol produced from coal mining wastes could range between $6.20 and $7.86 per million Btu.

Ash limitation of physical coal beneficiation for medium–high ash coal—A geochemistry perspective  

Science Journals Connector (OSTI)

Abstract Nowadays the industrial coal beneficiation in China could only reduce the ash yield to about 10%, which could not meet the requirement or standard of environment protection. In this work, the possibility of reducing the ash yield was studied from the aspect of geochemistry. The channel samples were collected from two coal seams in Guizhou and Shanxi province, China and then conducted analysis by combining data from coals worldwide. The result reveals that the same coal seam or the coals deposited in the same peat swamp show a significantly positive correlation between ash yield and Al2O3 + SiO2 content, and the intercept of regression equation on the ash axis is always less than 5% (generally 2–5%). Overall, the coal from China is featured with a higher intercept compared with that in the other countries. The intercept of 2–5% on the ash axis indicates an original inorganic component in coal-forming peat. The research result also presents a theoretical limitation of coal ash by coal cleaning, because 2–5% of inorganic components in medium–high quality ash coal could hardly be separated by traditional physical coal beneficiation.

Clean coal  

SciTech Connect

The article describes the physics-based techniques that are helping in clean coal conversion processes. The major challenge is to find a cost- effective way to remove carbon dioxide from the flue gas of power plants. One industrially proven method is to dissolve CO{sub 2} in the solvent monoethanolamine (MEA) at a temperature of 38{sup o}C and then release it from the solvent in another unit when heated to 150{sup o}C. This produces CO{sub 2} ready for sequestration. Research is in progress with alternative solvents that require less energy. Another technique is to use enriched oxygen in place of air in the combustion process which produces CO{sub 2} ready for sequestration. A process that is more attractive from an energy management viewpoint is to gasify coal so that it is partially oxidized, producing a fuel while consuming significantly less oxygen. Several IGCC schemes are in operation which produce syngas for use as a feedstock, in addition to electricity and hydrogen. These schemes are costly as they require an air separation unit. Novel approaches to coal gasification based on 'membrane separation' or chemical looping could reduce the costs significantly while effectively capturing carbon dioxide. 1 ref., 2 figs., 1 photo.

Use of coal liquefaction catalysts for coal/oil coprocessing and heavy oil upgrading  

SciTech Connect

The catalytic hydrogenation of coal and model solvents using dispersed or supported catalysts at different pressures has been the focus of several recent studies at PETC. The effectiveness of these catalysts has been studied in coal liquefaction and coal-oil coprocessing. Coal-oil coprocessing involves the co-reaction of coal and petroleum-derived oil or resid. The results of these studies have indicated that both dispersed and supported catalysts are effective in these systems at elevated H{sub 2} pressures ({approximately}2,500 psig). Attempts to reduce pressure indicated that a combination of catalyst concentration and solvent quality could be used to compensate for reductions in H{sub 2} pressure. Comparison of the coal and coprocessing systems reveals many similarities in the catalytic requirements for both systems. Both hydrogenation and hydrogenolysis activities are required and the reactive environments are similar. Also, the use of catalysts in the two systems shares problems with similar types of inhibitors and poisons. The logical extension of this is that it may be reasonable to expect similar trends in catalyst activity for both systems. In fact, many of the catalysts selected for coal liquefaction were selected based on their effectiveness in petroleum systems. This study investigates the use of supported and dispersed coal liquefaction catalysts in coal-oil coprocessing and petroleum-only systems. The focus of the study was delineating the effects of coal concentration, pressure, and catalyst type.

Clean Coal Technology Program Clean Coal Technology Program Clean Coal 101 Lesson 2: The Clean Coal Technology Program The Clean Coal Technology Program began in 1985 when the United States and Canada decided that something had to be done about the "acid rain" that was believed to be damaging rivers, lakes, forests, and buildings in both countries. Since many of the pollutants that formed "acid rain" were coming from big coal-burning power plants in the United States, the U.S. Government took the lead in finding a solution. One of the steps taken by the U.S. Department of Energy was to create a partnership program between the Government, several States, and private companies to test new methods developed by scientists to make coal burning much cleaner. This became the "Clean Coal Technology Program."

Reaching an agreement to build a new coal-fired power plant near a national park by mitigating potential environmental impacts  

SciTech Connect

This paper presents an interesting example of compromise through comprehensive environmental analysis and intensive negotiation to build a coal-fired power plant near an environmentally sensitive area. In December 1993, the US Department of Energy (DOE) completed the final environmental impact statement (EIS) for the Healy Clean Coal Project (HCCP), a proposed demonstration project that would be cost-shared by DOE and the Alaska Industrial Development and Export Authority (AIDEA). The HCCP would be built adjacent to the existing coal-fired Golden Valley Electric Association, Inc. (GVEA) Unit No. 1 in Healy, Alaska, about 4 miles north of Denali National Park and Preserve (DNPP). In response to US Department of the Interior (DOI) concerns about potential air quality related impacts on DNPP, DOE facilitated negotiations among DOI, AIDEA, and GVEA which overcame a ``stalemate`` situation. A Memorandum of Agreement was signed by all four parties, enabling DOI to withdraw its objections. The cornerstone of the Agreement is the planned retrofit of Unit No. 1 to reduce emissions of sulfur dioxide and oxides of nitrogen. if the demonstration technologies operate as expected, combined emissions from the Healy site would increase by only about 8% but electrical generation would triple. The Agreement is a ``win/win`` outcome: DOE can demonstrate the new technologies, AIDEA can build a new power plant for GVEA to operate, and DOI can safeguard the pristine environment of DNPP.

Characterization of particulate matter (PM10) related to surface coal mining operations in Appalachia  

Science Journals Connector (OSTI)

This study investigates the environmental exposure of residents of a community in southwest Virginia to respirable concentrations of dust (PM-10 i.e. PM10) generated by trucks hauling coal from surface coal mining operations. The study site is representative of communities in southwest Virginia and other parts of Appalachia that are located in narrow hollows where homes are placed directly along roads that experience heavy coal truck traffic. Preliminary air sampling (Particulate Matter i.e. PM10) was conducted for a period of approximately two weeks during early August 2008 in the unincorporated community of Roda, Virginia, at two locations (about a mile apart along Roda Road (Route 685) in Wise County, Virginia). For the purposes of this study (a combination of logistics, resource, and characterization of PM) we sited the PM samplers near the road to ascertain the micro exposure from the road. The results revealed high levels of PM10 (the mean adjusted 24-h concentration at the Campbell Site = 250.2 ?g m?3 (±135.0 ?g m?3); and at the Willis Site = 144.8 ± 60.0 ?g m?3). The U.S. 24-h national ambient air quality standard for PM10 is 150 ?g m?3. Elemental analysis for samples (blank-corrected) collected on Quartz filter paper (on one randomly selected day) at both the sites revealed the presence of antimony, arsenic, beryllium, cadmium, chromium, cobalt, lead, manganese, mercury, nickel, selenium. Electron micrographs reveal the morphology and habit (shapes and aggregates) of the particulate matter collected.

Evaluating the feasibility of underground coal gasification in Thailand  

SciTech Connect

Underground coal gasification (UCG) is a clean coal technology that converts in situ coal into a low- to medium-grade product gas without the added expense of mining and reclamation. Potential candidates for UCG are those coal resources that are not economically recoverable or that are otherwise unacceptable for conventional coal utilization processes. The Energy and Environmental Research Center (EERC), through the sponsorship of the US Trade and Development Agency and in collaboration with the Electricity Generating Authority of Thailand (EGAT), is undertaking a feasibility study for the application of UCG in the Krabi coal mining area, 620 miles south of Bangkok in Thailand. The EERC`s objective for this project is to determine the technical, environmental, and economic feasibility of demonstrating and commercializing UCG at a selected site in the Krabi coal mining area. This paper addresses the preliminary developments and ongoing strategy for evaluating the selected UCG site. The technical, environmental, and economic factors for successful UCG operation are discussed, as well as the strategic issues pertaining to future energy expansion in southern Thailand.

Pricing of Australia's coking coal exports: A regional hedonic analysis  

Science Journals Connector (OSTI)

Black coal is Australia's most important export commodity, but the profitability of the domestic coal industry has been low relative to the mining sector average. As a consequence, a key policy issue in Australia has been the extent to which Japan's coal pricing and investment policies have influenced coal market outcomes. In this paper, a regional hedonic pricing model of Australia's coking coal exports is estimated for the period JFY1989 to 1996. Non-Japan regional intercept dummy variables were found to be significantly different from zero, although these varied across coal categories and years. However, the empirical evidence indicates that Japan does not pay significantly lower prices relative to other major export markets for coking coal of a given quality.

Surface modified coals for enhanced catalyst dispersion and liquefaction  

SciTech Connect

The aim of the study is to enhance catalyst loading and dispersion in coal for improved liquefaction by preadsorption of surfactants and catalysts on to the coal. During this reporting period, zeta potential measurements were conducted to assess the surface charge on the raw, pretreated and catalyzed coal samples. The surface area, transmission spectroscopy and luminescence intensity of the raw coal and pretreated coal samples were also determined to assess the quality of the coal surface. Across a broad range of pH values, the raw coal had an overall negative charge. Coal treated with anionic surfactant SDS maintained an overall net negative surface negative charge. The interaction between the coal and cationic surfactant DDAB caused the opposite effect resulting in a more positive coal surface charge. Although one would have expected little or no effect of the neutral surfactant Triton X-100, there appears to be some difference in the results of the raw coal and the coal treated with Triton X-100. The authors believe that the Triton not only binds to the nonpolar sites but also has a strong affinity for the polar sites through electrostatic bonding and interaction between the hydrophobic tails. The addition of molybdenum to coal pretreated with DDAB caused a reduction in the positive charge of the coal surface probably due to possible ionic interaction between the coal surface, the surfactant and the catalyst. The adsorption isotherm of the coal was characteristic of isotherms for porous samples and the surface area of the coal increased from 30 m{sup 2}/g to 77 m{sup 2}/g when washed with deionized water. This suggests coal washing may be one method of increasing the surface area for surfactant adsorption. Although the transmission measurements provided valuable information about the coal it resulted in little information on the amount of adsorbed Triton. However, the maximum solid-liquid ratio for optimum surfactant loading of Triton X-100 was determined via the UV-Vis spectrophotometer. The luminescence intensity measurements showed that the coal and surfactants luminescence weakly. No statistically significant influence was observed from the actions of the surfactants or surfactant-molybdenum catalyst. Qualitative inspection however, showed that SDS might effectively coat coal surfaces and influence catalyst dispersion. Also, catalysts appeared to be better distributed among coal particles and in finer clusters when DDAB and Triton surfactants were used.

Hidden costs of the accident at Three Mile Island  

SciTech Connect

It has been possible to identify a significant drop in the performance of Pressurised Water Reactors (PWRs) in the western world following the accident at Three Mile Island (TMI). Although there are indications that the magnitude of the load factor reduction was slightly larger in the U.S., there is nevertheless strong evidence to suggest that the response was felt in all countries with operating PWRs. The effect did not, however, extend to other reactor systems; even the generically similar Boiling Water Reactor (BWR) suffered no drop in output. It is estimated that the costs, worldwide, of this fall in performance are of the same order as the TMI clean-up operation.

Refined methods for the evaluation of coal resources, quantum leaps in productivity  

SciTech Connect

Studies of coal resource evaluations have been constantly refined since the inception of the Joint Coal Availability Project between the Kentucky Geological Survey and the U.S. Geological Survey in the mid 1980's. Originally geological, environmental, social and technical data was collected and analyzed on individual 7.5 minute quadrangles (areas of 50 to 60 square miles). Mineable coal beds were correlated using the best available data and map and mining information accuracy were closely scrutinized. Advancements in Geographical Information Systems (GIS) and the development of regional databases have allowed the US GS to model the geology and mining restrictions in the same detail, but, for much larger areas coal fields and basins, than in the past. This paper will discuss the GIS programs, methodologies, and computer hardware used in the coal evaluations, and results of Illinois, Powder River, and San Juan Basins and Wasatch Plateau studies.

Eisenbeis, Supt. of Conservation THE FIRST COAL PLANTS Coal has been called "the mainspring" of our civilization. You are probably familiar, in a general way, with the story of how it originated ages ago from beds of peat which were very slowly changed to coal; and how it became lignite or brown coal, sub-bituminous, bituminous, or anthracite coal, depending on bacterial and chemical changes in the peat, how much it was compressed under terrific pressure, and the amount of heat involved in the process. You also know that peat is formed by decaying vegetation in shallow clear fresh-water swamps or bogs, but it is difficult to find a simple description of the kinds of plants that, living and dying during different periods of the earth's history, created beds of peat which eventually became coal.

Vegetation survey of Four Mile Creek wetlands. [Savannah River Plant  

SciTech Connect

A survey of forested wetlands along upper Four Mile Creek was conducted. The region from Road 3 to the creek headwaters was sampled to evaluate the composition of woody and herbaceons plant communities. All sites were found to fall into either the Nyssa sylvatica (Black Gum) -- Persea borbonia (Red Bay) or Nyssa sylvatica -- Acer rubrum (Red Maple) types. These community types are generally species-rich and diverse. Previous studies (Greenwood et al., 1990; Mackey, 1988) demonstrated contaminant stress in areas downslope from the F- and H-Area seepage basins. In the present study there were some indications of contaminant stress. In the wetland near H-Area, shrub basal area, ground cover stratum species richness, and diversity were low. In the area surrounding the F-Area tree kill zone, ground cover stratum cover and shrub basal area were low and ground cover stratum species richness was low. The moderately stressed site at F-Area also showed reduced overstory richness and diversity and reduced ground cover stratum richness. These results could, however, be due to the very high basal area of overstory trees in both stressed F-Area sites that would reduce light availability to understory plants. No threatened or endangered plant species were found in the areas sampled. 40 refs., 4 figs., 8 tabs.

A novel technique for assessing the coking potential of coals/coal blends for non-recovery coke making process  

Science Journals Connector (OSTI)

Abstract In an effort to broaden the scope of coal selection, the authors have developed a novel procedure based on a coefficient, named as Composite Coking Potential (CCP). CCP value assesses the suitability of a coal/coal blend for producing coke of desired quality; measured by the parameter coke strength after reaction (CSR). The coking potential takes into account of various properties of the coals and their proportions in a given coal blend and convert them into a single value. This technique is having advantage since each of these parameters represents different aspects of the coking phenomena along with inter dependence of some of these parameters also exists. This makes the coal selection process extremely difficult and in majority of the cases, decision is taken based on experience. In this investigation, CCP model has been used for selecting the least expensive coal blends which will comply with the minimum coke quality requirements of blast furnace. The study confirms the inter relations between the CCP and the hot strength of coke i.e. CSR. Actual plant data of a non-recovery coke oven have been used for developing and validation of the model. The technique was successfully used in identifying cheaper coals for producing coke with desired quality.

Bio-coal briquette  

SciTech Connect

Some of the developing nations aim to earn foreign currency by exporting oil and/or gas and to increase the domestic consumption of coal to ensure a secure energy supply. Therefore, it is very important to promote effective coal utilization in these nations. Currently, these countries experience problems associated with coal use for household cooking and household industries. For household cooking, coal creates too much smoke and smells unpleasant. In addition, illegally obtained firewood is almost free in local agricultural regions. Coal is also used in household industries; however, simple stoker boilers are inefficient, since unburned coal particles tend to drop through screens during the combustion process. The bio-coal briquette, on the other hand, is an effective and efficient fuel, since it utilizes coal, which is to be used extensively in households and in small and medium-scale industry sectors in some coal-producing countries, as a primary fuel and bamboos (agricultural waste) as a secondary fuel. In addition, the use of bio-coal briquettes will greatly help reduce unburned coal content.

Coal properties and system operating parameters for underground coal gasification  

SciTech Connect

Through the model experiment for underground coal gasification, the influence of the properties for gasification agent and gasification methods on underground coal gasifier performance were studied. The results showed that pulsating gasification, to some extent, could improve gas quality, whereas steam gasification led to the production of high heating value gas. Oxygen-enriched air and backflow gasification failed to improve the quality of the outlet gas remarkably, but they could heighten the temperature of the gasifier quickly. According to the experiment data, the longitudinal average gasification rate along the direction of the channel in the gasifying seams was 1.212 m/d, with transverse average gasification rate 0.069 m/d. Experiment indicated that, for the oxygen-enriched steam gasification, when the steam/oxygen ratio was 2:1, gas compositions remained stable, with H{sub 2} + CO content virtually standing between 60% and 70% and O{sub 2} content below 0.5%. The general regularities of the development of the temperature field within the underground gasifier and the reasons for the changes of gas quality were also analyzed. The 'autopneumatolysis' and methanization reaction existing in the underground gasification process were first proposed.

Chemical comminution of coal  

SciTech Connect

The objective of the present research is to study the chemical reactivity of a mixture of methyl alcohol and aqueous sodium hydroxide solution in the temperature range 298 to 363 K, and a caustic concentration of 0 to 10 wt. %, on an Iowa bituminous coal. The sample studied was collected from coal zone 4, equivalent to most historical references to Laddsdale coal. The coals in this zone are typical high-sulfur, high-ash middle Pennsylvania Cherokee group coals. The apparent rank is high-volatile C bituminous coal. The relatively high content of sulfur and 23 other elements in these coals is related to near neutral (6-8) pH conditions in the depositional and early diagenetic environments, and to postdepositional sphalerite/calcite/pyrite/kaolinite/barite mineralization.

Coal dust explosibility  

Science Journals Connector (OSTI)

This paper reports US Bureau of Mines (USBM) research on the explosibility of coal dusts. The purpose of this work is to improve safety in mining and other industries that process or use coal. Most of the tests were conducted in the USBM 20 litre laboratory explosibility chamber. The laboratory data show relatively good agreement with those from full-scale experimental mine tests. The parameters measured included minimum explosible concentrations, maximum explosion pressures, maximum rates of pressure rise, minimum oxygen concentrations, and amounts of limestone rock dust required to inert the coals. The effects of coal volatility and particle size were evaluated, and particle size was determined to be at least as important as volatility in determining the explosion hazard. For all coals tested, the finest sizes were the most hazardous. The coal dust explosibility data are compared to those of other hydrocarbons, such as polyethylene dust and methane gas, in an attempt to understand better the basics of coal combustion.

Coal: the new black  

SciTech Connect

Long eclipsed by oil and natural gas as a raw material for high-volume chemicals, coal is making a comeback, with oil priced at more than $100 per barrel. It is relatively cheap feedstock for chemicals such as methanol and China is building plants to convert coal to polyolefins on a large scale and interest is spreading worldwide. Over the years several companies in the US and China have made fertilizers via the gasification of coal. Eastman in Tennessee gasifies coal to make methanol which is then converted to acetic acid, acetic anhydride and acetate fiber. The future vision is to convert methanol to olefins. UOP and Lurgi are the major vendors of this technology. These companies are the respective chemical engineering arms of Honeywell and Air Liquide.

Modification of sub-bituminous coal by steam treatment: Caking and coking properties  

Science Journals Connector (OSTI)

A Chinese sub-bituminous Shenfu (SF) coal was steam treated under atmospheric pressure and the caking and coking properties of the treated coals were evaluated by caking indexes (GRI) and crucible coking characterizations. The results show that steam treatment can obviously increase the GRI of SF coal. When the steam treated coals were used in the coal blends instead of SF raw coal, the micro-strength index (MSI) and particle coke strength after reaction (PSR) of the coke increased, and particle coke reactivity index (PRI) decreased, which are beneficial for metallurgical coke to increase the gas permeability in blast furnace. The quality of the coke obtained from 8% of 200 °C steam treated SF coal in coal blends gets to that of the coke obtained from the standard coal blends, in which there was no SF coal addition in the coal blends. The removal of oxygen groups, especially hydroxyl group thus favoring the breakage of the coal macromolecules and allowing the treated coal formation of much more amount of hydrocarbons, may be responsible for the modified results. The mechanism of the steam treatment was proposed based on the elemental analysis, thermo gravimetric (TG) and FTIR spectrometer characterizations of the steam treated coal.

Profitability analysis of non-coking coal preparation for power plants in India  

SciTech Connect

Currently coal-based power plants produce about 70% of the total electricity generated in India, where non-coking (steam) coals are utilized mostly without any preparation. A massive capacity addition of at least 140,000 MWe is required (over the 81,000 MWe of current installed capacity) during the next 15 years to meet growing energy demand. Such a rapid expansion of power generation capacity poses a serious challenge to the environment (at emission controls) and transportation infrastructure in India. Furthermore, the high ash content of indigenous coals and concentration of coal mines in central and northeastern India away from urban centers exacerbate the problem. Thus, coal preparation is envisioned to play a major role in shaping the energy future of India. Under the Indo-US Coal Preparation Program, the US Department of Energy`s Pittsburgh Energy Technology Center (PETC) is coordinating coal preparation activities for the US Agency for International Development. In this context, a detailed analysis of the washability characteristics of non-coking coals was performed using the PETC Coal Preparation Plant Simulator (CPPS) to identify coal preparation strategies for India. Based on these strategies, a profitability analysis of non-coking coal preparation has been conducted considering coal preparation and transportation costs, and coal quality impacts on power plant operations. This paper summarizes the results of this analysis and quantifies the significance of coal preparation for the Indian power sector.

Coal Storage and Transportation  

Science Journals Connector (OSTI)

Abstract Coal preparation, storage, and transportation are essential to coal use. Preparation plants, located near to the mine, remove some inorganic minerals associated with raw coal. Coal is transported from the mines to the point of consumption, often an electric generating plant, by rail, barge and trucks. Railroads are the predominant form of coal transportation within a country. Global coal trade, movement by large ocean-going vessels, continues to increase. At the end use site, the coal is crushed, ground, and the moisture content reduced to the proper specifications for end use. Coal is stored at various points in the supply chain. Processed coal will weather and oxidize, changing its properties; it can self-ignite, unless precautions are taken. Technology in use today is similar to that used in previous decades. Performance improvements have come from improved software and instruments that deliver real-time data. These improve management of sub-processes in the coal supply chain and reduce costs along the supply chain.

Effects of Surface Chemistry on the Porous Structure of Coal  

SciTech Connect

In this report, 129 Xe nuclear magnetic resonance spectroscopy of xenon gas adsorbed in coal is used to describe some poorly understood features of coal microporous structure, particularly in establishing that a connected network exists, the type of connectivity, and its changes with the rank of coal. Micropore size scale and distribution are also considered. Two methods are developed which are new and versatile tools for the investigation of porous structure. Both utilize xenon gas that is in motion, while undergoing diffusion or exchange in coal, to describe the connectivity of the micropore structure of coal. Time tracking of the adsorption process by NMR, selective saturation, and saturation transfer techniques were used to obtain new information on the coal rank dependence of porous structure. In addition, an existing 129 Xe chemical shift-pore diameter model was used to calculate micropore diameters for coals, as well as for a microporous carbon, before and after pore-size alteration. In the initial study performed, straightforward 129 Xe NMR spectra at equilibrium xenon adsorption at a series of pressures were acquired for a rank-varied set of six coals. Acquisition of the NMR signal as an echo was tested and found to improve spectral quality. The spectra were used to calculate micropore diameters for the six coals. These range from 5.6 to 7.5 ? and exhibit a minimum value for the intermediate coal rank. The smallest pores occur in coals of about 82-85% carbon; at both lower and higher coal ranks, the average micropore size tends to be larger. The changes in the spectra with coal rank and surface area were explored. Signal linewidths were found to decrease with increasing coal rank and were interpreted in terms of increasing chemical or physical homogeneity of the coal as rank increases. The packing density of powdered coal was found to alter the spectral appearance in a high volatile bituminous coal, which is preliminary evidence that exchange affects the chemical shift of xenon in this coal.

Potential benefits from and barriers against coal remining  

SciTech Connect

Coal has been mined commercially in the United States since the mid 1700s and strip mining of coal began in the in the late 1800S. However, until the past 15--20 years, the environmental effects of coal mining caused little concern. In the past, coal mining sites were abandoned for economic reasons or because the equipment in use at the time could not recover any additional coal. Many of these sites were left in an unsafe and unsightly condition, resulting in severe water quality problems and threats to public health and safety. In more recent times, the advent of more sophisticated equipment allowed operators to return to previously mined sites and recover additional coal. This practice, known as remining, is the subject of this paper. In the most general sense, remining is simply mining again at a site that had formerly been mined. Many of today`s coal mining activities take place entirely or partially at sites that were formerly mined and left unreclaimed, primarily because no laws existed requiring reclamation. This paper focuses on the subset of remining projects, which not only recover additional coal, but also reclaim or improve the condition of abandoned mine lands (AMLs), particularly improvements to water quality.

Coal geology of the U.S. Gulf Coastal region  

SciTech Connect

The US Geological Survey (USGS) is conducting a comprehensive assessment of the major coal regions of the country. In this program, known as the National Coal Resource Assessment, the quantity and quality of coals that are expected to be mined during the next 30 years will be characterized. For the Gulf Coast region, the evaluation will include reviews of the stratigraphic setting, resource potential, and the quality of the lignites in four coal-producing areas. These areas are: the Sabine Uplift (including parts of Texas and Louisiana), Northeast Texas, Central Texas, and South Texas. The results of these efforts will be a series of digital Geographic Information System (GIS) maps, text, and tables that will be published in a CD-ROM format. These products, along with a national summary CD-ROM, are expected to be completed in 1999. This paper is to present a review of Gulf Coast coal geology and to outline the USGS assessment efforts for the Gulf Coast region. Most coal in the Gulf Coast area is produced from the Paleocene Wilcox Group, and minor amounts of coal are produced from the Ecocene Jackson and Claiborne Groups. Initial results indicate that for coals being mined in the Sabine Uplift, Northeast, and Central Texas areas mean moisture values are about 34%, mean ash yields range from 12 to 15%, and mean calorific values range from about 5,800 to 6,900 Btu/lb (all data are on an as-received basis). Detailed bed and zone analysis in all areas indicate that resource figures will be greater than previous estimates that have usually combined multiple coal horizons to estimate cumulative coal thicknesses for a formation. Ongoing research in the Sabine Uplift and Northeast study areas suggests that coal zones in both the upper and lower Wilcox may be more laterally extensive than previous studies indicate.

Coal combustion by-products: State regulatory overview  

SciTech Connect

Coal combustion by-products (CCBs) are generated from the combustion of coal for energy production. Approximately 82 million tons of CCBs are produced each year by electric utilities. (1991 Coal Combustion By-Product Production and Use, American Coal Ash Association, 1992.) There are several common types of CCBs produced by coal combustion--fly ash, bottom ash, boiler slag, flue gas desulfurization material (FGD) and fluidized bed combustion byproducts (FBC). Some CCBs, such as fly ash, have pozzolanic properties and may have cementitious properties, both of which are advantageous for engineering, construction and waste remediation applications. The American Society for Testing Materials (ASTM) in ASTM C-618 has created two classifications of useful and quality coal ash, Class F ash and Class C ash. Each class of coal ash has different pozzolanic and cementitious characteristics. Coal ash can be utilized in many manufacturing, mining, agricultural, engineering, construction and waste remediation applications. This is a review by state of regulations concerning coal combustion by-products.

The clean coal technologies of today are already capable of reducing, if not eliminating, harmful emissions. The technologies of the future will allow coal to be burned with greatly reduced emissions, thus eliminating the necessity to treat them after they occur.

Coal liquefaction quenching process  

DOE Patents (OSTI)

There is described an improved coal liquefaction quenching process which prevents the formation of coke with a minimum reduction of thermal efficiency of the coal liquefaction process. In the process, the rapid cooling of the liquid/solid products of the coal liquefaction reaction is performed without the cooling of the associated vapor stream to thereby prevent formation of coke and the occurrence of retrograde reactions. The rapid cooling is achieved by recycling a subcooled portion of the liquid/solid mixture to the lower section of a phase separator that separates the vapor from the liquid/solid products leaving the coal reactor.

The United States Department of Energy (US DOE) Clean Coal Technology Demonstration Program (also referred to as the CCT Program) is a government and industry cofunded technology development effort to demonstrate a new generation of innovative coal utilization processes in a series of {open_quotes}semicommercial{close_quotes} facilities. These demonstrations are on a scale large enough to generate all the data, from design, construction, and operation, that are necessary for the private sector to judge commercial potential and make informed, confident decisions on commercial readiness. The projects in the program are demonstrating technologies that will encompass advanced electric power generation systems, high-performance pollution control devices, coal processing for clean fuels and industrial applications. The innovative CCTs being demonstrated offer tremendous potential as solutions to many complex problems in a rapidly changing arena dominated by energy, economic, and environmental issues. These issues include the following: air quality; global climate change; energy security; international competitiveness; acid rain; power production; and technology awareness. These technologies are expected to be of particular importance to the utility industry. Power production in the United States, particularly in the form of electricity, is expected to increase rapidly during the next 20 years. The growth in electricity consumption between 1990 and 2000 translates into the need for at least an additional 200,000 MWe of capacity by 2010. The ability to continue to use coal to produce electricity and as a source of industrial heat and power is critical. In the United States approximately 86 percent of coal is critical. The CCT Program is developing through demonstration new power and steam production systems using coal-based technologies that will permit coal to be a clean, efficient, reliable source of affordable energy.

Coal in China  

SciTech Connect

The article gives an overview of the production and use of coal in China, for power generation and in other sectors. Coal use for power generation was 850 million tonnes in 2003 and 800 million tonnes in the non-power sector. The majority of power will continue to be produced from coal, with a trend towards new larger pulverised coal fired units and introduction of circulating fluidised bed combustors. Stricter regulations are forcing introduction of improved pollution control technologies. It seems likely that China will need international finance to supplement private and state investment to carry out a programme to develop and apply clean coal technologies. The author concludes that there is evidence of a market economy being established but there is a need to resolve inconsistencies with the planned aspects of the economy and that additional policies are needed in certain sectors to achieve sustainable development. 1 ref., 2 figs., 2 tabs.

Influence of combustion conditions and coal properties on physical properties of fly ash generated from pulverized coal combustion  

SciTech Connect

To develop combustion technology for upgrading the quality of fly ash, the influences of the coal properties, such as the size of pulverized coal particles and the two-stage combustion ratio during the combustion, on the fly ash properties were investigated using our test furnace. The particle size, density, specific surface area (obtained by the Blaine method), and shape of fly ash particles of seven types of coal were measured. It was confirmed that the size of pulverized coal particles affects the size of the ash particles. Regarding the coal properties, the fuel ratio affected the ash particle size distribution. The density and shape of the ash particles strongly depended on their ash size. Our results indicated that the shape of the ash particles and the concentration of unburned carbon affected the specific surface area. The influence of the two-stage combustion ratio was limited. 8 refs., 13 figs., 3 tabs.

Annual prospects for world coal trade 1985: with projections to 1995  

SciTech Connect

The Energy Information Administration (EIA) projects US and world coal trade to 1995, and annually updates the projections in the Annual Energy Outlook. The current projections assume that world coal trade will expand between now and 1995 in response to increasing demand for steam coal. US coal exports rose rapidly between 1979 and 1981, from 66 million short tons to 113 million short tons, partly as a result of labor problems in Poland and Australia. After declining slightly to 106 million short tons in 1982, US coal exports decreased sharply to 78 million short tons in 1983 due to increased supplies of Polish coal in Western Europe and Australian coal in Asia. Moreover, the continued strength of the US dollar made US coal more expensive overseas. US coal exports rose slightly in 1984, to 81 million short tons. Exports of US coal in 1985 are projected to be approximately 71 million short tons. As a high-cost supplier of export coal, the United States has been the ''swing supplier'' because of its ability to ship large amounts of coal on short notice. The United States is likely to maintain a significant share of the world market as a reliable supplier of high-quality coal. EIA projections of US coal exports and world coal trade for 1990 and 1995 are provided in a mid-demand (or base) case as well as in two other cases, a low-demand case and a high-demand case, that reflect uncertainties in the projections. EIA estimates of import coal demand for 1990 and 1995 were developed using key energy supply and demand information for the principal coal-importing countries in Western Europe and Asia, and evaluating that information in the context of estimated trends in economic growth and energy use. 3 figs., 26 tabs.

The Coal Logistics System: Documentation and user's guide  

SciTech Connect

The Coal Logistics System (CLS) has the capability to track coal from a US mine or mining area to a foreign consumer's receiving dock. The system contains substantial quantities of information about the types of coal available in different US coalfields, present and potential inland transportation routes to tidewater piers, and shipping routes to and port capabilities in the five importing nations now included. It is designed to facilitate comparisons of coal quality and price at several stages of the export process, including delivered prices at a wide range of destinations from Trieste to Vado Ligure in Italy, and from Muroran in northern Japan, to Sri Racha, near Bangkok, along the Asian Pacific Rim. The CLS can also be used to examine coal quality within or between any of 18 US coalfields, including three in Alaska, or compare alternative routes and associated service prices between coal producing regions and ports-of-exit. It may be used to explore the possibilities of different ship sizes, marine routes, and foreign receiving terminals for coal exports. The CLS interacts with users through a series of menus that provide the user with simple choices. 30 figs.

Spatial characteristic of coal geochemistry: Some methodological considerations  

SciTech Connect

Identification and analysis of spatial patterns in coal geochemistry have important implications in coal science, notably for coal quality prediction, resource evaluation, and for interpretation of geological controls on coal geochemistry. Contour maps of elemental concentration for coal deposits may be reconstructed from raw data by using one of a number of interpolation methods commonly used within the earth sciences. Within a Geographic Information System (GIS), these surfaces may then be analyzed, and be integrated or compared with the distribution surfaces of other attributes such as coal petrography, seam thickness or mineralogy. The exact shape of the reconstructed geochemical contour map will vary depending on the method of interpolation selected and how the researcher chooses to divide data into classes by selection of class intervals. This paper and the associated poster presentation examine the range of output which may result when some of these methodological parameters are varied. Guidelines for selection of interpolation methodologies and data classification are suggested. A data set consisting of 14 coal samples from the Bullmoose mine area in northeastern British Columbia, Canada is used to illustrate the difference in coal geochemical surface reconstruction when using different interpolation techniques and class intervals.

Advanced coal technologies in Czech heat and power systems  

SciTech Connect

Coal is the only domestic source of fossil fuel in the Czech Republic. The coal reserves are substantial and their share in total energy use is about 60%. Presently necessary steps in making coal utilisation more friendly towards the environment have been taken and fairly well established, and an interest to develop and build advanced coal units has been observed. One IGCC system has been put into operation, and circa 10 AFBC units are in operation or under construction. Preparatory steps have been taken in building an advanced combustion unit fuelled by pulverised coal and retrofit action is taking place in many heating plants. An actual experience has shown two basic problems: (1) Different characteristic of domestic lignite, especially high content of ash, cause problems applying well-tried foreign technologies and apparently a more focused attention shall have to be paid to the quality of coal combusted. (2) Low prices of lignite (regarding energy, lignite is four times cheaper then coal) do not oblige to increase efficiency of the standing equipment applying advanced technologies. It will be of high interest to observe the effect of the effort of the European Union to establish a kind of carbon tax. It could dramatically change the existing scene in clean coal power generation by the logical pressure to increase the efficiency of energy transformation. In like manner the gradual liberalisation of energy prices might have similar consequences and it is a warranted expectation that, up to now not the best, energy balance will improve in near future.

Blackout: coal, climate and the last energy crisis  

SciTech Connect

Coal fuels more than 30 per cent of UK electricity production, and about 50 per cent in the US, providing a significant portion of total energy output. China and India's recent ferocious economic growth has been based almost entirely on coal-generated electricity. Coal currently looks like a solution to many of our fast-growing energy problems. However, while coal advocates are urging us full steam ahead, the increasing reliance on this dirtiest of all fossil fuels has crucial implications for energy policy, pollution levels, the global climate, world economy and geopolitics. Drawbacks to a coal-based energy strategy include: Scarcity - new studies suggest that the peak of world coal production may actually be less than two decades away; Cost - the quality of produced coal is declining, while the expense of transportation is rising, leading to spiralling costs and increasing shortages; and, Climate impacts - our ability to deal with the historic challenge of climate change may hinge on reducing coal consumption in future years.

Water effects of the use of western coal for electrical production  

SciTech Connect

Water may be a constraint on the expanded development of coal resources in the semi-arid western United States. Water allocation in the West has been determined by the appropriative rights doctrine which allows perpetual use of water sources by those who first claim it for beneficial purposes. This has had the effect of placing a dominative interest in water allocation in one economic sector: agriculture. New water sources are available to coal producers but political and economic problems must be overcome. Water is required by every phase of coal development. Mines use water for dust control and land reclamation. Coal slurry pipelines would use water as a transport medium. Steam electric power plants use water for cooling, cleaning, and in the boiler. Coal gasification plants would use water for cooling, cleaning, and as a material input. In addition to these direct uses of water by coal development, the people who build and operate the development demand water for domestic and recreational purposes. The quantity of water required for a given element of a coal development is site specific and dependent on many factors. The available literature cites a range of estimates of the amount of water required for each type of development. The width of this range seems related to the stage of development of the particular technology. Estimates of water requirements for various schemes to provide an average electrical load of 9 GWe to a load center 1000 miles from western mines are shown in Table 5.

Th e United States also has more coal reserves than any other single country in the world. In fact, 1/4 of all the known coal in the world is in the United States. Th e United States has more energy in coal that can be mined than the rest of the world has in oil that can be pumped from the ground. Currently, coal is mined in 25 of the 50 states. Coal is used primarily in the United States to generate electricity. In fact, it is burned in power plants to produce nearly half of the electricity we use.

Vehicle routing for the last mile of power system restoration  

SciTech Connect

This paper studied a novel problem in power system restoration: the Power Restoration Vehicle Routing Problem (PRVRP). The goal of PRVRPs is to decide how coordinate repair crews effectively in order to recover from blackouts as fast as possible after a disaster has occurred. PRVRPs are complex problems that combine vehicle routing and power restoration scheduling problems. The paper proposed a multi-stage optimization algorithm based on the idea of constraint injection that meets the aggressive runtime constraints necessary for disaster recovery. The algorithms were validated on benchmarks produced by the Los Alamos National Laboratory, using the infrastructure of the United States. The disaster scenarios were generated by state-of-the-art hurricane simulation tools similar to those used by the National Hurricane Center. Experimental results show that the constraint-injection algorithms can reduce the blackouts by 50% or more over field practices. Moreover, the results show that the constraint-injection algorithm using large neighborhood search over a blackbox simulator provide competitive quality and scales better than using a MIP solver on the subproblems.

Coal combustion products (CCPs  

Energy.gov (U.S. Department of Energy (DOE)) Indexed Site

combustion products (CCPs) combustion products (CCPs) are solid materials produced when coal is burned to generate electricity. Since coal provides the largest segment of U.S. electricity generation (45 percent in 2010), finding a sustainable solution for CCPs is an important environmental challenge. When properly managed, CCPs offer society environmental and economic benefits without harm to public health and safety. Research supported by the U.S. Department of Energy's (DOE) Office of Fossil Energy (FE) has made an important contribution in this regard.

Modelling coal gasification  

Science Journals Connector (OSTI)

Coal gasification processes in a slurry-feed-type entrained-flow gasifier are studied. Novel simulation methods as well as numerical results are presented. We use the vorticity-stream function method to study the characteristics of gas flow and a scalar potential function is introduced to model the mass source terms. The random trajectory model is employed to describe the behaviour of slurry-coal droplets. Very detailed results regarding the impact of the O2/coal ratio on the distribution of velocity, temperature and concentration are obtained. Simulation results show that the methods are feasible and can be used to study a two-phase reacting flow efficiently.

Coal liquefaction process  

DOE Patents (OSTI)

A process is described for the liquefaction of coal wherein raw feed coal is dissolved in recycle solvent with a slurry containing recycle coal minerals in the presence of added hydrogen at elevated temperature and pressure. The highest boiling distillable dissolved liquid fraction is obtained from a vacuum distillation zone and is entirely recycled to extinction. Lower boiling distillable dissolved liquid is removed in vapor phase from the dissolver zone and passed without purification and essentially without reduction in pressure to a catalytic hydrogenation zone where it is converted to an essentially colorless liquid product boiling in the transportation fuel range. 1 fig.

REFINERY INTEGRATION OF BY-PRODUCTS FROM COAL-DERIVED JET FUELS  

SciTech Connect

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

This lab experiment illustrates the use of thermogravimetric analysis (TGA) to perform proximate analysis on a series of coal samples of different rank. Peat and coke are also examined. A total of four exercises are described. These are dry exercises as students interpret previously recorded scans. The weight percent moisture, volatile matter, fixed carbon, and ash content are determined for each sample and comparisons are made. Proximate analysis is performed on a coal sample from a local electric utility. From the weight percent sulfur found in the coal (determined by a separate procedure the Eschka method) and the ash content, students calculate the quantity of sulfur dioxide emissions and ash produced annually by a large coal-fired electric power plant.

Caustic washing for refining of direct coal liquefaction products  

SciTech Connect

Extensive research and development sponsored by the U.S. DOE/PETC over the past two decades has resulted in dramatic improvements in the quality of direct coal liquefaction products. High-quality coal-derived distillates are obtainable from catalytic two-stage liquefaction (TSL) processes, such as those developed at the Wilsonville, AL pilot plant and the Hydrocarbon Technologies Inc. (HTI) pilot plant and bench units. The products of the Wilsonville and HTI TSL operations are suitable as high quality feedstocks for producing transportation fuels in a refinery. These products have important quality advantages over crude petroleum: they are distillates boiling below about 700{degrees}F and are thus virtually free of resid and metals, and they have very low sulfur contents and low nitrogen contents. The coal liquids have carbon and hydrogen contents and Watson characterization factors within the range of crude petroleums. However, relative to crude petroleum, the crude coal products have elevated oxygen contents. This report describes the removal of phenols from coal liquids by caustic washing, and the the recovery of the cresylic acid by-product.

Section 5 - Coal  

Science Journals Connector (OSTI)

Coal has the longest history of use among the fossil fuels, with use as a fuel dating to 3000 BC in China and Wales. Marco Polo’s “Description of the World” (1298) comments on many novel customs and practices of China, including the use of “stones that burn like logs” (coal). By the thirteenth century the mining of coal was widespread in England in regions such as Durham, Nottinghamshire, Derbyshire, Staffordshire, and North and South Wales. By the early seventeenth century nearly half of England’s maritime trade consisted of coal exports. Coal was the fuel that launched the Industrial Revolution in Europe and then the United States. By the late 1890s, the U.S. assumed the lead in world coal production. Britain now ranked second, after having been the world leader since the beginnings of the formal industry in the 1500s. Germany was third, an indication of its growing industrial power relative to continental rival France. Coal’s leading role in energy use peaked in the early twentieth century, after which it was supplanted by oil and natural gas. By the late twentieth century China’s rapid economic expansion, surging demand for electricity, and prodigious coal resources combined to propel it to become the world leader in production. Continuous improvements in coal mining technology have produced lower costs, improved safety, and greater labor productivity. John Buddle introduced the first air pump to ventilate coal mines (1803), followed shortly by the miner’s safety lamps that were developed independently by Sir Humphry Davy, William Clanny, and George Stephenson (1813-1816). Coal mining underwent a rapid transition in the 1880s to mechanical coal cutting in mines in the United Kingdom, the United States, and Russia. The St. Joseph Lead Company of Missouri (1900) invented the first underground mine roof bolts that became a key safety feature in underground coal mines. The first commercially successful bucket wheel excavator was used at the Luise Mine in Braunkohlemwerke, Germany (1925), followed by the first successful continuous miners in U.S. underground coal mining (1948). The first mechanized U.S. longwall mining system appeared in 1951, and was followed by the self-advancing hydraulic longwall support system that provided greater support for the roof of the mine. LeTourneau Technologies, Inc. of Texas manufactured the largest rubber tired front-end wheel loader in the world, the L-2350, which would play an important role in loading coal in Wyoming’s large surface mines (2005). Coal mining has always been a very hazardous occupation, and has produced some of history’s worst industrial disasters. The Courrières mine disaster, Europe's worst mining accident, caused the death of 1,099 miners in Northern France (1906). An explosion in a coal mine in Liaoning province in northeastern China killed more than 1,500 Chinese miners (1942), as did other major accidents in Ky?sh?, Japan (1914), Wankie, Rhodesia (1972), Wales (1913), Bihar, India (1965), and West Virginia, U.S. (1907), to name just a few. Legislation such as the Federal Coal Mine Health and Safety Act in the U.S. (1969) improved working conditions in many nations. The Great Smog of London (1952) occurred after an exceptionally cold winter forced homes and factories to burn large quantities of coal. A temperature inversion formed, trapping pollutants above the ground. More than 4,000 people died from respiratory ailments within the following week. The use of coal has been impacted by legislation to control the environmental impacts associated with its mining and combustion. The first known environmental regulation of coal dates to 1306 when King Edward II of England prohibited burning sea coal while Parliament was in session because of its offensive smoke. Sulfur dioxide from coal combustion was tied to acid rain in the 1960s, and carbon dioxide emissions became a concern beginning in the 1980s when climate change emerged as a critical environmental issue.

Coal science for the clean use of coal  

SciTech Connect

Coal will need to be retained as a major source of energy in the next century. It will need to be used more effectively and more cleanly. In order to achieve this, it is necessary to introduce new technology supported by a local community of science and technology. Only in this way can the full benefits of international advances in coal utilization be fully achieved. It is important that full advantage be taken of the advances that have been achieved in laboratory techniques and in the better understanding of fundamental coal science. This paper reviews available technologies in power generation, industrial process heat, coal combustion, coal gasification, and coal analytical procedures.

Fort Union coals of the northern Rockies and Great Plains: A linchpin toward a new approach to national coal resource assessment  

SciTech Connect

The U.S. Geological Survey recently initiated a 5-year program to assess the Nation`s coal resources, which emphasizes a new approach relating coal quantity and quality. One assessment region includes the northern Rocky Mountains and Great Plains of Wyoming, Montana, and North Dakota, which contains a vast expanse of Paleocene Fort Union coal-bearing rocks that yielded about 30% (>299 million short tons) of the total coal produced (1.03 billion short tons) in the U.S. for 1994. Production is from 14 coal beds/zones (Wyodak-Anderson, Anderson-Dietz, Rosebud, Beulah-Zap, Hagel, Harmon, Ferris Nos. 23, 24, 25, 31, 38, 39, Hanna No. 80, and Deadman seams) mined in the Hanna, Green River, Powder River, and Williston Basins. About 254 million short tons produced from 25 mines are from the Wyodak-Anderson, Anderson-Dietz, and Rosebud coal beds/zones in the Powder River Basin (PRB). These coals are considered as clean and low contaminant compliance coals containing less sulfur and ash (arithmetic mean for sulfur is 0.58% and ash is 7%, as-received basis) than coals produced from other regions in the conterminous U.S. Preliminary elemental analysis of coal samples from the PRB for those hazardous air pollutants (HAPs) named in the Amendments to the 1990 Clean Air Act (including Sb, As, Be, Cd, Cr, Co, Pb, Mn, Hg, Ni, Se, and U), indicates that PRB coals are lower in HAPs contents than other coals from within the region and also other regions in the U.S. Arithmetic means of HAPs contents of these coals are: Sb=0.35, As=3.4, Be=0.6, Cd=0.08, Cr=6.1, Co=1.6, Pb=3.6, Mn=23.5, Hg=0.09, Ni=4.6, Se=0.9, and U=1.1 (in ppm, as-received, and on a whole-coal basis). These coal-quality parameters will be used to delineate coal quantity of the 14 Fort Union coal beds/zones defined in the resource assessment for expanded utilization of coals into the next several decades as controlled by present and future environmental constraints.

A procedure for producing maps and resource tables of coals assessed during the US Geological Survey`s National Coal Assessment  

SciTech Connect

In the Colorado Plateau region of the US, more than 20 coal zones in 5 formations are currently being assessed for the US Geological Survey (USGS) National Coal Resource Assessment. Certain steps in the process of calculating coal resource estimates and producing the numerous accompanying maps for each assessment unit must therefore, be automated. Through trial and error the authors have established an accurate, reliable, and time-efficient method of taking an ASCII formatted file containing location (x,y) and coal thickness data, combining this with multiple layers of digital spatial data pertaining to coal distribution and coal resource reporting parameters, to ultimately arrive at high quality end products. They utilize as many as six commercially available software packages in conjunction with three custom programs to process the digital data. These programs range from simple conversion programs to highly sophisticated Geographic Information Systems (GIS), 2-dimensional modeling programs, graphics packages, and spread sheet software. The method is explained.

A supply chain network design model for biomass co-firing in coal-fired power plants  

SciTech Connect

We propose a framework for designing the supply chain network for biomass co-firing in coal-fired power plants. This framework is inspired by existing practices with products with similar physical characteristics to biomass. We present a hub-and-spoke supply chain network design model for long-haul delivery of biomass. This model is a mixed integer linear program solved using benders decomposition algorithm. Numerical analysis indicates that 100 million tons of biomass are located within 75 miles from a coal plant and could be delivered at $8.53/dry-ton; 60 million tons of biomass are located beyond 75 miles and could be delivered at $36/dry-ton.

Method of extracting coal from a coal refuse pile  

DOE Patents (OSTI)

A method of extracting coal from a coal refuse pile comprises soaking the coal refuse pile with an aqueous alkali solution and distributing an oxygen-containing gas throughout the coal refuse pile for a time period sufficient to effect oxidation of coal contained in the coal refuse pile. The method further comprises leaching the coal refuse pile with an aqueous alkali solution to solubilize and extract the oxidized coal as alkali salts of humic acids and collecting the resulting solution containing the alkali salts of humic acids. Calcium hydroxide may be added to the solution of alkali salts of humic acid to form precipitated humates useable as a low-ash, low-sulfur solid fuel.

Coal combustion system  

DOE Patents (OSTI)

In a coal combustion system suitable for a gas turbine engine, pulverized coal is transported to a rich zone combustor and burned at an equivalence ratio exceeding 1 at a temperature above the slagging temperature of the coal so that combustible hot gas and molten slag issue from the rich zone combustor. A coolant screen of water stretches across a throat of a quench stage and cools the combustible gas and molten slag to below the slagging temperature of the coal so that the slag freezes and shatters into small pellets. The pelletized slag is separated from the combustible gas in a first inertia separator. Residual ash is separated from the combustible gas in a second inertia separator. The combustible gas is mixed with secondary air in a lean zone combustor and burned at an equivalence ratio of less than 1 to produce hot gas motive at temperature above the coal slagging temperature. The motive fluid is cooled in a dilution stage to an acceptable turbine inlet temperature before being transported to the turbine.

Pyrolysis of coal  

DOE Patents (OSTI)

A method for mild gasification of crushed coal in a single vertical elongated reaction vessel providing a fluidized bed reaction zone, a freeboard reaction zone, and an entrained reaction zone within the single vessel. Feed coal and gas may be fed separately to each of these reaction zones to provide different reaction temperatures and conditions in each reaction zone. The reactor and process of this invention provides for the complete utilization of a coal supply for gasification including utilization of caking and non-caking or agglomerating feeds in the same reactor. The products may be adjusted to provide significantly greater product economic value, especially with respect to desired production of char having high surface area.

Process for coal liquefaction employing selective coal feed  

DOE Patents (OSTI)

An improved coal liquefaction process is provided whereby coal conversion is improved and yields of pentane soluble liquefaction products are increased. In this process, selected feed coal is pulverized and slurried with a process derived solvent, passed through a preheater and one or more dissolvers in the presence of hydrogen-rich gases at elevated temperatures and pressures, following which solids, including mineral ash and unconverted coal macerals, are separated from the condensed reactor effluent. The selected feed coals comprise washed coals having a substantial amount of mineral matter, preferably from about 25-75%, by weight, based upon run-of-mine coal, removed with at least 1.0% by weight of pyritic sulfur remaining and exhibiting vitrinite reflectance of less than about 0.70%.

Abstract The chapter discusses various techniques for coal seam degasification. All coal seams are gassy but they differ in their degree of gassiness. Pre-mining and post-mining techniques for underground coal mines are discussed. With good planning, 50–80% of in-situ gas in coal can be removed before mining improving both safety and productivity. Similarly, 50–80% of gas from mined-out areas (gobs) can be removed to minimize ventilation air requirements. Gas transport in underground mines and economics of coal seam degasification are also discussed.

Abstract: Coal resources still make up a significant proportion of the world’s energy supplies. Coal resources are estimated to be 860 billion tonnes. These resources are geographically well distributed and current production provides fuel for 29% of the world’s primary energy consumption. The classification of coal resources and reserves has been redefined in recent years, with the standards and codes of practice adopted by the principal coal-producing countries being equated on a global basis. Details of the principal classifications are given, together with their international equivalents. Reporting of resources and reserves plus methods of calculation are also given, together with recent assessments of global coal reserves.

Drag reduction in coal log pipelines  

SciTech Connect

It is well-known that solutions of dissolved long-chain macromolecules produce lower friction or drag losses than with the solvent alone. In coal log pipeline (CLP), water is the conveying medium. Synthetic polymers such as poly(ethylene oxide) have been dissolved in water and tested for their extent of drag reduction as a function of concentration and other variables. Lab-scale experimental results for CLP indicate substantial drag reduction at low concentration levels of polymer. But, the macromolecules exhibit degradation under mechanical shear stresses. The large molecules break into smaller units. This degradation effect causes a loss of drag reduction. However, high levels of drag reduction can be maintained as follows: (1) by injecting polymer into the CLP at several locations along the pipeline, (2) by injecting polymer of different particle sizes, (3) by using more robust types of polymers, or (4) by using polymer-fiber mixtures. This report presents the value of drag-reducing agents in terms of pumping power net cost savings. In addition, this report outlines the environmental impact of drag reduction polymers, and end-of-pipeline water treatment processes. For an operating CLP, hundreds of miles in length, the use of poly(ethylene oxide) as a drag reducing agent provides significant pumping power cost savings at a minimal materials cost.

Although coal use is expected to be displaced by natural gas in some parts of the world, Although coal use is expected to be displaced by natural gas in some parts of the world, only a slight drop in its share of total energy consumption is projected by 2020. Coal continues to dominate many national fuel markets in developing Asia. Historically, trends in coal consumption have varied considerably by region. Despite declines in some regions, world coal consumption has increased from 84 quadrillion British thermal units (Btu) in 1985 to 93 quadrillion Btu in 1997. Regions that have seen increases in coal consumption include the United States, Japan, and developing Asia. Declines have occurred in Western Europe, Eastern Europe, and the countries of the former Soviet Union (FSU).

Coal continues to dominate many national fuel markets in developing Asia. World coal consumption has been in a period of generally slow growth since the late 1980s, a trend that is expected to continue. Although 1999 world consumption, at 4.7 billion short tons,9 was 15 percent higher than coal use in 1980, it was lower than in any year since 1984 (Figure 51). The International Energy Outlook 2001 (IEO2001) reference case projects some growth in coal use between 1999 and 2020, at an average annual rate of 1.5 percent, but with considerable variation among regions.

Coal-oil slurry preparation  

DOE Patents (OSTI)

A pumpable slurry of pulverized coal in a coal-derived hydrocarbon oil carrier which slurry is useful as a low-ash, low-sulfur clean fuel, is produced from a high sulfur-containing coal. The initial pulverized coal is separated by gravity differentiation into (1) a high density refuse fraction containing the major portion of non-coal mineral products and sulfur, (2) a lowest density fraction of low sulfur content and (3) a middlings fraction of intermediate sulfur and ash content. The refuse fraction (1) is gasified by partial combustion producing a crude gas product from which a hydrogen stream is separated for use in hydrogenative liquefaction of the middlings fraction (3). The lowest density fraction (2) is mixed with the liquefied coal product to provide the desired fuel slurry. Preferably there is also separately recovered from the coal liquefaction LPG and pipeline gas.

Characteristics of coking coal burnout  

SciTech Connect

An attempt was made to clarify the characteristics of coking coal burnout by the morphological analysis of char and fly ash samples. Laboratory-scale combustion testing, simulating an ignition process, was carried out for three kinds of coal (two coking coals and one non-coking coal for reference), and sampled chars were analyzed for size, shape and type by image analysis. The full combustion process was examined in industrial-scale combustion testing for the same kinds of coal. Char sampled at the burner outlet and fly ash at the furnace exit were also analyzed. The difference between the char type, swelling properties, agglomeration, anisotropy and carbon burnout were compared at laboratory scale and at industrial scale. As a result, it was found that coking coals produced chars with relatively thicker walls, which mainly impeded char burnout, especially for low volatile coals.

Underground Coal Thermal Treatment  

SciTech Connect

The long-term objective of this work is to develop a transformational energy production technology by insitu thermal treatment of a coal seam for the production of substitute natural gas (SNG) while leaving much of the coalâ??s carbon in the ground. This process converts coal to a high-efficiency, low-GHG emitting gas fuel. It holds the potential of providing environmentally acceptable access to previously unusable coal resources. This topical report discusses the development of experimental capabilities, the collection of available data, and the development of simulation tools to obtain process thermo-chemical and geo-thermal parameters in preparation for the eventual demonstration in a coal seam. It also includes experimental and modeling studies of CO{sub 2} sequestration. Efforts focused on: â?¢ Constructing a suite of three different coal pyrolysis reactors. These reactors offer the ability to gather heat transfer, mass transfer and kinetic data during coal pyrolysis under conditions that mimic in situ conditions (Subtask 6.1). â?¢ Studying the operational parameters for various underground thermal treatment processes for oil shale and coal and completing a design matrix analysis for the underground coal thermal treatment (UCTT). This analysis yielded recommendations for terms of targeted coal rank, well orientation, rubblization, presence of oxygen, temperature, pressure, and heating sources (Subtask 6.2). â?¢ Developing capabilities for simulating UCTT, including modifying the geometry as well as the solution algorithm to achieve long simulation times in a rubblized coal bed by resolving the convective channels occurring in the representative domain (Subtask 6.3). â?¢ Studying the reactive behavior of carbon dioxide (CO{sub 2}) with limestone, sandstone, arkose (a more complex sandstone) and peridotite, including mineralogical changes and brine chemistry for the different initial rock compositions (Subtask 6.4). Arkose exhibited the highest tendency of participating in mineral reactions, which can be attributed to the geochemical complexity of its initial mineral assemblage. In experiments with limestone, continuous dissolution was observed with the release of CO{sub 2} gas, indicated by the increasing pressure in the reactor (formation of a gas chamber). This occurred due to the lack of any source of alkali to buffer the solution. Arkose has the geochemical complexity for permanent sequestration of CO{sub 2} as carbonates and is also relatively abundant. The effect of including NH{sub 3} in the injected gas stream was also investigated in this study. Precipitation of calcite and trace amounts of ammonium zeolites was observed. A batch geochemical model was developed using Geochemists Workbench (GWB). Degassing effect in the experiments was corrected using the sliding fugacity model in GWB. Experimental and simulation results were compared and a reasonable agreement between the two was observed.

Barge loading facilities in conjunction with wood chipping and sawlog mill, Tennessee River Mile 145. 9R: Environmental assessment  

SciTech Connect

The purpose of this Environmental Assessment (EA) is to evaluate the environmental consequences of approving, denying, or adopting reasonable alternatives to a request for barge loading facilities. These facilities would serve a proposed wood chipping and sawlog products operation at Tennessee River Mile (TRM) 145.9, right descending bank, (Kentucky Lake), in Perry County, Tennessee. The site is located between Short Creek and Peters Landing. The applicant is Southeastern Forest Products, L.P. (SFP), Box 73, Linden, Tennessee and the proposed facilities would be constructed on or adjacent to company owned land. Portions of the barge terminal would be constructed on land over which flood easement rights are held by the United States of America and administered by the Tennessee Valley Authority (TVA). The US Army Corps of Engineers (CE) and TVA have regulatory control over the proposed barge terminal facilities since the action would involve construction in the Tennessee River which is a navigable water of the United States. The wood chipping and sawlog products facilities proposed on the upland property are not regulated by the CE or TVA. On the basis of the analysis which follows, it has been determined that a modified proposal (as described herein) would not significantly affect the quality of the human environment, and does not require the preparation of an environmental impact statement. 8 refs.

The Wyodak-Anderson coal assessment, Powder River Basin, Wyoming and Montana -- An ArcView project  

SciTech Connect

In 1997, more than 305 million short tons of clean and compliant coal were produced from the Wyodak-Anderson and associated coal beds and zones of the Paleocene Fort Union Formation in the Powder River Basin, Wyoming and Montana. To date, all coal produced from the Wyodak-Anderson, which averages 0.47 percent sulfur and 6.44 percent ash, has met regulatory compliance standards. Twenty-eight percent of the total US coal production in 1997 was from the Wyodak-Anderson coal. Based on the current consumption rates and forecast by the Energy Information Administration (1996), the Wyodak-Anderson coal is projected to produce 413 million short tons by the year 2016. In addition, this coal deposit as well as other Fort Union coals have recently been targeted for exploration and development of methane gas. New US Geological Survey (USGS) digital products could provide valuable assistance in future mining and gas development in the Powder River Basin. An interactive format, with querying tools, using ArcView software will display the digital products of the resource assessment of Wyodak-Anderson coal, a part of the USGS National Coal Resource Assessment of the Powder River Basin. This ArcView project includes coverages of the data point distribution; land use; surface and subsurface ownerships; coal geology, stratigraphy, quality and geochemistry; and preliminary coal resource calculations. These coverages are displayed as map views, cross sections, tables, and charts.

Greater commitment needed to solve continuing problems at Three Mile Island. Report to the Congress  

SciTech Connect

The Nation's first major accident at a commercial nuclear-powered electricity generating station occurred at Three Mile Island over 2 years ago, yet the resolution of the resultant problems is still subject to regulatory and financial uncertainty. Consequently, little progress has been made to clean up the damaged facility or alleviate the extreme financial stress placed upon its owners. The remedies required to resolve the continuing problems at Three Mile Island will require unprecedented coordination and commitment by Federal and State regulatory bodies, the electric utility industry, the financial community, and the owners of the damaged facility. To safeguard against similar problems in the future, the Nuclear Regulatory Commission should develop accident recovery guidelines and ensure that increased property insurance coverage is available for nuclear facilities.

Coal surface control for advanced physical fine coal cleaning technologies  

SciTech Connect

This final report presents the research work carried out on the Coal Surface Control for Advanced Physical Fine Coal Cleaning Technologies project, sponsored by the US Department of Energy, Pittsburgh Energy Technology Center (DOE/PETC). The project was to support the engineering development of the selective agglomeration technology in order to reduce the sulfur content of US coals for controlling SO[sub 2] emissions (i.e., acid rain precursors). The overall effort was a part of the DOE/PETCs Acid Rain Control Initiative (ARCI). The overall objective of the project is to develop techniques for coal surface control prior to the advanced physical fine coal cleaning process of selective agglomeration in order to achieve 85% pyrite sulfur rejection at an energy recovery greater than 85% based on run-of-mine coal. The surface control is meant to encompass surface modification during grinding and laboratory beneficiation testing. The project includes the following tasks: Project planning; methods for analysis of samples; development of standard beneficiation test; grinding studies; modification of particle surface; and exploratory R D and support. The coal samples used in this project include three base coals, Upper Freeport - Indiana County, PA, Pittsburgh NO. 8 - Belmont County, OH, and Illinois No. 6 - Randolph County, IL, and three additional coals, Upper Freeport - Grant County- WV, Kentucky No. 9 Hopkins County, KY, and Wyodak - Campbell County, WY. A total of 149 drums of coal were received.

Illinois coal reserve assessment and database development. Final report  

SciTech Connect

The new demonstrated reserve base estimate of coal of Illinois is 105 billion short tons. This estimate is an increase from the 78 billion tons in the Energy Information Administration`s demonstrated reserve base of coal, as of January 1, 1994. The new estimate arises from revised resource calculations based on recent mapping in a number of countries, as well as significant adjustments for depletion due to past mining. The new estimate for identified resources is 199 billion tons, a revision of the previous estimate of 181 billion tons. The new estimates incorporate the available analyses of sulfur, heat content, and rank group appropriate for characterizing the remaining coal resources in Illinois. Coal-quality data were examined in conjunction with coal resource mapping. Analyses of samples from exploration drill holes, channel samples from mines and outcrops, and geologic trends were compiled and mapped to allocate coal resource quantities to ranges of sulfur, heat content, and rank group. The new allocations place almost 1% of the demonstrated reserve base of Illinois in the two lowest sulfur categories, in contrast to none in the previous allocation used by the Energy Information Administration (EIA). The new allocations also place 89% of the demonstrated reserve base in the highest sulfur category, in contrast to the previous allocation of 69% in the highest category.

Progress in donor assisted coal liquefaction: Hydroaromatic compound formation  

SciTech Connect

The role of hydrogen donor compounds in coal liquefaction has been extensively investigated since the mid 1960`s using model compounds and process derived hydrogen donor solvents. Our recent research and that of other investigators have shown that two model compounds in particular have great efficacy in solvating low rank coals. 1,2,3,10b tetrahydrofluoranthene (H{sub 4}Fl) and 1,2,3,6,7,8 hexahydropyrene (H{sub 6}Py) have been used to dissolve Wyodak coal to > 95% soluble material as measured by tetrahydrofuran (THF). Although these hydrogen donors are very effective, they may not be found in any significant concentrations in actual liquefaction process recycle solvents. Therefore, studies with process derived recycle materials are necessary to understand donor solvent chemistry. The objective of this paper is to present results of solvent hydrogenation experiments using heavy distillate solvents produced during testing at the Wilsonville Advanced Coal Liquefaction Test Facility. We evaluated the impact of hydrogenation conditions upon hydrogen donor formation in process derived distillates and compared these process derived solvents with the highly effective H{sub 4}Fl and H{sub 6}Py donors in coal liquefaction tests. This paper presents data on reaction conditions used for distillate hydrotreating and subsequent coal liquefaction, with an aim toward understanding the relationship between reaction conditions and donor solvent quality in recycle distillates.

Underground coal gasification using oxygen and steam  

SciTech Connect

In this paper, through model experiment of the underground coal gasification, the effects of pure oxygen gasification, oxygen-steam gasification, and moving-point gasification methods on the underground gasification process and gas quality were studied. Experiments showed that H{sub 2} and CO volume fraction in product gas during the pure oxygen gasification was 23.63-30.24% and 35.22-46.32%, respectively, with the gas heating value exceeding 11.00 MJ/m{sup 3}; under the oxygen-steam gasification, when the steam/oxygen ratio stood at 2: 1, gas compositions remained virtually stable and CO + H{sub 2} was basically between 61.66 and 71.29%. Moving-point gasification could effectively improve the changes in the cavity in the coal seams or the effects of roof inbreak on gas quality; the ratio of gas flowing quantity to oxygen supplying quantity was between 3.1:1 and 3.5:1 and took on the linear changes; on the basis of the test data, the reasons for gas quality changes under different gasification conditions were analyzed.

Caking and coking properties of the thermal dissolution soluble fraction of a fat coal  

Science Journals Connector (OSTI)

Abstract In the coal blending for coke-making, fat coal has a very important role for the caking and coking properties of the coal blends. In this study, a fat coal was thermally dissolved, and the caking and coking properties of the thermal dissolution soluble factions (TDSFs) from different solvents and temperatures were characterized. It was found that the caking properties of \\{TDSFs\\} were better than that of fat raw coal. The \\{TDSFs\\} obtained from non-polar solvents have a higher caking property than those obtained from polar solvents at the same thermal dissolution (TD) temperature. During TD process, polar solvents can thermally dissolve more polyaromatic compounds into TDSF, thus increasing the softening temperature and decreasing the caking property of the TDSF. For the same TD solvent, the \\{TDSFs\\} obtained from higher temperatures have a lower caking property compared to those obtained from lower temperatures because of more aromatic components and oxygen functional groups entering them. Crucible coking determinations were carried out to evaluate the coking property of the TDSFs. The result suggests that when 5% of TDSF and 5% of non-caking sub-bituminous coal were used instead of the same amount of fat coal and gas coal, respectively in the coal blends, the quality of the coke obtained could get to the level of the coke obtained from the standard coal blends (i.e. without TDSF and sub-bituminous coal). Therefore, the use of TDSF in coal blending for coke-making is one of the effective methods for opening the coking coal resources.

Moist caustic leaching of coal  

DOE Patents (OSTI)

A process for reducing the sulfur and ash content of coal. Particulate coal is introduced into a closed heated reaction chamber having an inert atmosphere to which is added 50 mole percent NaOH and 50 mole percent KOH moist caustic having a water content in the range of from about 15% by weight to about 35% by weight and in a caustic to coal weight ratio of about 5 to 1. The coal and moist caustic are kept at a temperature of about 300.degree. C. Then, water is added to the coal and caustic mixture to form an aqueous slurry, which is washed with water to remove caustic from the coal and to produce an aqueous caustic solution. Water is evaporated from the aqueous caustic solution until the water is in the range of from about 15% by weight to about 35% by weight and is reintroduced to the closed reaction chamber. Sufficient acid is added to the washed coal slurry to neutralize any remaining caustic present on the coal, which is thereafter dried to produce desulfurized coal having not less than about 90% by weight of the sulfur present in the coal feed removed and having an ash content of less than about 2% by weight.

Process for changing caking coals to noncaking coals  

DOE Patents (OSTI)

Caking coals are treated in a slurry including alkaline earth metal hydroxides at moderate pressures and temperatures in air to form noncaking carbonaceous material. Hydroxides such as calcium hydroxide, magnesium hydroxide or barium hydroxide are contemplated for slurrying with the coal to interact with the agglomerating constituents. The slurry is subsequently dewatered and dried in air at atmospheric pressure to produce a nonagglomerating carbonaceous material that can be conveniently handled in various coal conversion and combustion processes.

Reserves and potential supply of low-sulfur Appalachian coal. Final report  

SciTech Connect

This project has two objectives. The first is to develop and test a methodology for determining economically mineable reserves of low-sulfur Appalachian coal. The second is to appraise the potential supply response to a very large increase in demand for low-sulfur Appalachian coal. The reserve determination procedure developed in the project applies criteria similar to those employed by mining engineers in assessing the commercial feasibility of mining properties. The procedure is relatively easy to apply, could be used to develop reserve estimates for a large sample of mining blocks for under $500,000, and produces reserve estimates very different from those produced from the criteria that have been used by the United States Bureau of Mines: with the more rigorous method developed in this project surface mineable reserves are much larger and deep mineable reserves are less than with the Bureau of Mines method. The appraisal of potential low-sulfur coal supply response assessed excess capacity, coal mining company outlook on reserves, and coal quality requirements. The appraisal concluded that ample coal meeting most buyers' requirements will probably be available in the near or long term at a price under $45 in 1984 dollars. However, coal quality requirements may prove a constraint for some buyers, and an upward surge in prices would probably occur in the event of legislation imposing requirements leading to greatly increased low-sulfur coal demand. 14 refs., 24 figs., 15 tabs.

Geochemistry of coal from Cretaceous Corwin and Chandler formations, National Petroleum Reserve in Alaska (NPRA)  

SciTech Connect

Ninety coal samples from these formations within NPRA were collected and analyzed in order to evaluate coal quality and elemental distribution. Their apparent rank ranges from lignite A in the northern part of NPRA to high-volatile AS bituminous coal in the southern part. Mean vitrinite reflectance values range from 0.65 to 0.74%. Some Corwin Formation coal samples west of NPRA have coking potential with free-swelling indexes between 3.0 and 5.0. Compared to other western United States Cretaceous coal, NPRA coal is significantly lower in ash, volatile matter, O, Si, Al, Ca, Fe, Ti, Cu, F, Li, Mn, Mo, Pb, Sb, Se, Th, and Zn. Statistical comparisons of element concentrations indicate that the mean content of Si, Al, K, Li, Sc, Y, and Yb increases as the mean ash content increases (correlation coefficient at least 0.7). Sulfur values are extremely low (0.1%), and elements that normally show positive correlation with sulfur, such as Fe, As, Cd, Co, Cu, Mo, Pb, and Zn, are also low. Therefore, coal from NPRA can be characterized by low ash and sulfur contents and low contents of elements of environmental concern, such as As, Be, Hg, Mo, Sb, and Se. The elements found to have positive correlations with ash content are probably present as aluminosilicate or stable oxide minerals. Variations in element content and quality of NPRA coal were probably influenced by the geochemical conditions that existed in the Corwin and Umiat delta systems.

Coal Bed Methane Primer  

SciTech Connect

During the second half of the 1990's Coal Bed Methane (CBM) production increased dramatically nationwide to represent a significant new source of income and natural gas for many independent and established producers. Matching these soaring production rates during this period was a heightened public awareness of environmental concerns. These concerns left unexplained and under-addressed have created a significant growth in public involvement generating literally thousands of unfocused project comments for various regional NEPA efforts resulting in the delayed development of public and fee lands. The accelerating interest in CBM development coupled to the growth in public involvement has prompted the conceptualization of this project for the development of a CBM Primer. The Primer is designed to serve as a summary document, which introduces and encapsulates information pertinent to the development of Coal Bed Methane (CBM), including focused discussions of coal deposits, methane as a natural formed gas, split mineral estates, development techniques, operational issues, producing methods, applicable regulatory frameworks, land and resource management, mitigation measures, preparation of project plans, data availability, Indian Trust issues and relevant environmental technologies. An important aspect of gaining access to federal, state, tribal, or fee lands involves education of a broad array of stakeholders, including land and mineral owners, regulators, conservationists, tribal governments, special interest groups, and numerous others that could be impacted by the development of coal bed methane. Perhaps the most crucial aspect of successfully developing CBM resources is stakeholder education. Currently, an inconsistent picture of CBM exists. There is a significant lack of understanding on the parts of nearly all stakeholders, including industry, government, special interest groups, and land owners. It is envisioned the Primer would being used by a variety of stakeholders to present a consistent and complete synopsis of the key issues involved with CBM. In light of the numerous CBM NEPA documents under development this Primer could be used to support various public scoping meetings and required public hearings throughout the Western States in the coming years.

Zero emission coal  

SciTech Connect

We discuss a novel, emission-free process for producing hydrogen or electricity from coal. Even though we focus on coal, the basic design is compatible with any carbonaceous fuel. The process uses cyclical carbonation of calcium oxide to promote the production of hydrogen from carbon and water. The carbonation of the calcium oxide removes carbon dioxide from the reaction products and provides the additional energy necessary to complete hydrogen production without additional combustion of carbon. The calcination of the resulting calcium carbonate is accomplished using the high temperature waste heat from solid oxide fuel cells (SOFC), which generate electricity from hydrogen fuel. Converting waste heat back to useful chemical energy allows the process to achieve very high conversion efficiency from fuel energy to electrical energy. As the process is essentially closed-loop, the process is able to achieve zero emissions if the concentrated exhaust stream of CO{sub 2} is sequestered. Carbon dioxide disposal is accomplished by the production of magnesium carbonate from ultramafic rock. The end products of the sequestration process are stable naturally occurring minerals. Sufficient rich ultramafic deposits exist to easily handle all the world's coal.

GIS data models for coal geology  

SciTech Connect

A variety of spatial data models can be applied to different aspects of coal geology. The simple vector data models found in various Computer Aided Drafting (CAD) programs are sometimes used for routine mapping and some simple analyses. However, more sophisticated applications that maintain the topological relationships between cartographic elements enhance analytical potential. Also, vector data models are best for producing various types of high quality, conventional maps. The raster data model is generally considered best for representing data that varies continuously over a geographic area, such as the thickness of a coal bed. Information is lost when contour lines are threaded through raster grids for display, so volumes and tonnages are more accurately determined by working directly with raster data. Raster models are especially well suited to computationally simple surface-to-surface analysis, or overlay functions. Another data model, triangulated irregular networks (TINs) are superior at portraying visible surfaces because many TIN programs support break fines. Break lines locate sharp breaks in slope such as those generated by bodies of water or ridge crests. TINs also {open_quotes}honor{close_quotes} data points so that a surface generated from a set of points will be forced to pass through those points. TINs or grids generated from TINs, are particularly good at determining the intersections of surfaces such as coal seam outcrops and geologic unit boundaries. No single technique works best for all coal-related applications. The ability to use a variety of data models, and transform from one model to another is essential for obtaining optimum results in a timely manner.

Synergistic Effect of coal blends on thermoplasticity evaluated using a temperature-variable dynamic viscoelastic measurement  

SciTech Connect

To maximize the conversion of low-quality coal into good coke, we investigated the thermoplasticity of various binary blends of caking coals with slightly or noncaking coals using a dynamic viscoelastic technique with a temperature-variable rheometer. Coal blend samples were prepared by mixing two coals (1:1 by weight), which were heated from room temperature to 600 C at a rate of 3-80{sup o}C/min. At the slow rate of 3{sup o}C/min, the blends had a tan {delta} that was generally lower than the calculated value, showing that a negative interaction caused a loss of thermoplasticity. In contrast, at the rapid heating rate of 80{sup o}C/min, the tan {delta} of some blends was higher than the calculated value, indicating a positive interaction that enhanced the thermoplasticity. With rapid heating, the thermoplasticity of each coal itself increased, and their thermoplastic temperature ranges widened with rapid heating. Therefore, rapid heating was effective at converting these coal blends into good cokes. Moreover, even with slow heating, whe
