Download or read book Processing and Utilization of High Sulfur Coals V written by B.K. Parekh and published by Elsevier. This book was released on 2013-10-22 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: Utilization of high sulfur coals is becoming increasingly difficult in view of tighter environmental regulations being imposed around the world. To meet the challenge of utilizing high sulfur coals without damaging the environment, many scientists and engineers around the world are engaged in developing novel technologies. In the U.S.A. alone, the federal government has spent about five billion dollars to achieve that goal. This conference, like its predecessors, emphasizes desulfurization with papers on physical and chemical cleaning as well as post-treatment and fluid-bed combustion technologies. Of the 45 papers submitted, 15 papers deal with physical cleaning and 7 deal with chemical cleaning of coal, suggesting that a major emphasis is still be placed on pre-cleaning of coal. The post-treatment technologies, being developed with the support of U.S. federal and state government agencies, emphasize removal of both SOx and NOx gases. The book will be of particular interest and benefit to researchers, graduate students and other people involved in coal processing, characterization and utilization; public policy making and administration related to energy conservation, economic development, and environmental protection; and investors in industry and new technology.

This book was released on 1991 with total page 852 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings comprise peer-reviewed articles summarizing the most recent progress made by many of the leaders of high-sulfur coal research and development in the past two years. Four papers cover the conversion of coals to liquid and gaseous products both as a means of removing sulfur and for increasing the utility and value of the coal. Improvements in coal cleaning technology by application of biological, physical and chemical processes, as well as combinations of these methods are reported. Methods of beneficiation including the emerging electrochemical and ultrasonic approaches are also presented. Several papers cover the fundamentals and applications of flotation as a technique for separating the sulfur from the carbon content of coal once the sulfur has been liberated from the coal matrix. One paper describes a microbial process for removing solubilized iron and sulfur (as sulfate) that have been liberated from coal. Eight contributions deal with the various aspects of cleaning potential atmospheric contaminants from coal combustion gasses.The book will be of particular interest and benefit to researchers, graduate students and all persons involved in coal production, processing and utilization; public policy making and administration related to energy conservation, economic development, and environmental protection; and investors in industry and new technology.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: 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.
Download or read book Advanced Coal Preparation and Beyond written by S. Komar Kawatra and published by CRC Press. This book was released on 2020-01-27 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Updating content from the author’s 2001 book Coal Desulfurization, this new title focuses on CO2 sequestration and utilization. It includes information on the theory and practical approaches to CO2 capture and recent advances in the use of sequestered CO2. Avoiding these pollutants requires either forgetting about the 250 billion tons of coal reserves the United States possesses or capturing and utilizing the pollutants in a profitable and environmentally responsible fashion. The book covers postcombustion and precombustion capture approaches for coal, and postcombustion capture can be generalized to many other fuels. Recent practical implementations at full-scale power facilities around the world are discussed. The book covers sequestering CO2 via underground, oceanic, biological, and other long-term CO2 storage methods. It also includes recent advances in utilizing CO2 for enhanced oil recovery, advances in storage with depleted oil and gas reservoirs and deep saline aquifers, and additional topics. The book also examines specific applications of pure CO2 and covers chemical conversion of CO2 to useful compounds. It answers questions like "Can we create methanol from coal?" or "Can we create ethanol from coal?" It is found that methanol and ethanol cannot be sustainably produced from coal power alone. However, oxalic acid can be created at a much lower energy cost than methanol or ethanol. Oxalic acid can be used to extract rare earths, which are not currently produced anywhere in the United States, but are typically concentrated in coal ash. Aimed at researchers and industry professionals in chemical, environmental, and energy engineering, this book provides insight and inspiration into capturing CO2 not merely as a response to regulatory pressure and climate change but as an inherently profitable and valuable venture.

Download or read book Challenges in Fine Coal Processing Dewatering and Disposal written by Mark S. Klima and published by SME. This book was released on 2012 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coal mining and preparation have had a long history in the United States and the world, serving as the engine of growth for many industries. Today, new sources of energy, increased environmental awareness, and more stringent regulations from the U.S. Environmental Protection Agency and other organizations are changing the way coal is found, extracted, and used. As a result, fine coal cleaning, dewatering, and refuse disposal are now at a major crossroads. The increased level of fines, and near-density material in the inferior seams being mined today, necessitates the development of more efficient fine coal cleaning devices. This in turn requires improvements in traditional dewatering techniques to address the need for acceptable moisture levels in plant products. Moreover, the larger volume of fine refuse being generated, coupled with harsher disposal regulations, requires upgraded treatment options. This book is a compilation of information presented at the 2012 Fine Coal Symposium, sponsored by the Coal Preparation Society of America; the Pittsburgh Section of the Society for Mining, Metallurgy, and Exploration, Inc.; and the Pittsburgh Coal Mining Institute of America. Provided by international coal companies, major research organizations, technology developers, and industry leaders, the information includes both general knowledge and in-depth discussion on the current challenges facing the industry, techniques for designing more efficient plants, and new cleaning and dewatering technologies. The book is a practical yet cutting-edge resource for plant designers, engineers, and other practitioners, and for university students and faculty.

Download or read book Atmospheric Fluidized Bed Coal Combustion written by M. Valk and published by Elsevier. This book was released on 2013-10-22 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of fluidized bed coal combustion technology has been developed in the past decade in The Netherlands with a view to expanding the industrial use of coal as an energy supply. Various research groups from universities, institutes for applied science and from boiler industries participated and contributed to this research area. Comprehensive results of such recent experimentation and development work on atmospheric fluidized bed combustion of coal are covered in this volume. Each chapter, written by an expert, treats one specific subject and gives both the theoretical background as well as experimental results and verifications. Though the contents deal primarily with coal combustion, much information proved applicable and relevant for the combustion or incineration of other solid fuels and waste in a fluidized bed. Results of extended research and fundamental backgrounds are presented in order to provide the designer and operator of fluidized bed combustors with more complete and systematic information needed for an optimal design and operation. The design and operating experience of a full scale fluidized bed boiler are discussed and compared with the results of theoretical and experimental research on pilot plant scale.
