Bridging the gap in expertise between coal and coalbed gas, subfields in which opportunities for cross training have been nonexistent, Coal and Coalbed Gas sets the standard for publishing in these areas. This book treats coal and coalbed gas as mutually inclusive commodities in terms of their interrelated origin, accumulation, composition, distribution, generation, and development, providing a balanced understanding of this energy mix. Currently considered a non-renewable energy resource, coalbed gas, or coalbed methane, is a form of natural gas extracted from coal beds. In recent years, countries have begun to seek and exploit coal for its clean gas energy in an effort to alleviate environmental issues that come with coal use, making a book on this topic particularly timely. This volume takes into account processes of coalification, gasification, and storage and reservoir characterization and evaluation and looks at water management and environmental impacts as well. - Covers environmental issues in the development of coalbed gas - Includes case studies, field guides and data, examples, and analytical procedures from previous studies and investigations - Accessible by a large multidisciplinary market by one of the world's foremost experts on the topic
The 1965 Lignite Symposium, the fourth in a series and the third sponsored by the University of North Dakota, and the Bureau of Mines, was held at Bismark, N. Dak., on April 29-30, 1965. These symposia provide a forum for those interested in the technology and utilization of solid fuels, especially lignitic coals. As part of the meeting, a 200-mile field trip was taken including inspection of (1) the 200-metawatt, pulverized lignite-fired Leland Olds plant of Basin Electric Power Cooperative, under construction near Stanton, N. Dak.; (2) the site of the Glenharold mine of the Truax-Traer Coal Co., Division of Consolidation Coal Co., where a wheel excavator was being assembled; (3) the operating Beulah mine of Knife River Coal Mining Co., subsidiary fo Montana Dakota Utilities Co., near Beulah, N. Dak.; and (4) the 400-megawatt, hydroelectric Garrison Dam powerplant, near Garrison, N. Dak. During the technical sessions, 13 papers were presented covering some the recent trends, development, and research in lignite technology. The text of these papers is compiled to provide a record of the symposium and to allow wider dissemination of the information. Proceedings of the previous symposia have been published.
This book was written to provide a comprehensive survey of the current state-of-the-art information in coal preparation, with particular emphasis on coal desulfrization. The primary audience for this book will be practising coal preparation engineers who need complete information about all of the coal preparation and desulphurization technologies that are available now, or that may be available in the future. It will also be valuable for coal researchers who need details and comparative data for cutting-edge technologies that are still under development. The main emphasis is on physical coal preparation, but chapters also include chemical and biological technologies that are under development, but not yet used in industrial practice. Along with the successful technologies, also included are details of processes and techniques that were attempted, but were subsequently abandoned, along with discussions of the reasons they were abandoned.
Coal will continue to provide a major portion of energy requirements in the United States for at least the next several decades. It is imperative that accurate information describing the amount, location, and quality of the coal resources and reserves be available to fulfill energy needs. It is also important that the United States extract its coal resources efficiently, safely, and in an environmentally responsible manner. A renewed focus on federal support for coal-related research, coordinated across agencies and with the active participation of the states and industrial sector, is a critical element for each of these requirements. Coal focuses on the research and development needs and priorities in the areas of coal resource and reserve assessments, coal mining and processing, transportation of coal and coal products, and coal utilization.
The 1967 Lignite Symposium was held at Grand Forks, N. Dak., on April 27-28, 1967. This was the fifth of these technical meetings and the fourth which was cosponsored by the University of North Dakota and the Bureau of Mines. These symposia have provided a meeting place where current developments concerning technology and utilization of solid fuels (lignite) are presented. There was a registration of 255 persons from 24 States, the District of Columbia, six Canadian Provinces, Germany, and India. Many segments of coal or energy oriented organizations at many levels were represented. During the meeting, 18 presentations were made covering developments in electrical power generation, mining, estimation of reserves, combustion, gasification, and chemical and speciality uses of low-rank coals; these are compiled in this Information Circular to provide a record of the symposium and to permit wider dissemination of the information. Proceedings of the other meetings have also been published.
All the guidance needed to test coal and analyze the results With the skyrocketing costs of most fuel sources, government, industry, and consumers are taking a greater interest in coal, an abundant and inexpensive alternative, which has been made more environmentally friendly through new technology. Published in response to this renewed interest, Handbook of Coal Analysis provides readers with everything they need to know about testing and analyzing coal. Moreover, it explains the meaning of test results and how these results can predict coal behavior and its corresponding environmental impact during use. The thorough coverage of coal analysis includes: * Detailed presentation of necessary standard tests and procedures * Explanation of coal behavior relative to its usage alongside the corresponding environmental issues * Coverage of nomenclature, terminology, sampling, and accuracy and precision of analysis * Step-by-step test method protocols for proximate analysis, ultimate analysis, mineral matter, physical and electrical properties, thermal properties, mechanical properties, spectroscopic properties, and solvent properties * Emphasis on relevant American Society for Testing and Materials (ASTM) standards and test methods, including corresponding International Organization for Standardization (ISO) and British Standards Institution (BSI) test method numbers To assist readers in understanding the material, a glossary of terms is provided. Each term is defined in straightforward language that enables readers to better grasp complex concepts and theory. References at the end of each chapter lead readers to more in-depth discussions of specialized topics. This is an essential reference for analytical chemists, process chemists, and engineers in the coal industry as well as other professionals and researchers who are looking to coal as a means to decrease dependence on foreign oil sources and devise more efficient, cleaner methods of energy production.
