Download or read book Coal Desulfurization written by S. K. Kawatra and published by Taylor & Francis. This book was released on 2001 with total page 376 pages. Available in PDF, EPUB and Kindle. 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.

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 Processing and Utilization of High sulfur Coals V written by John George Groppo and published by Elsevier Science & Technology. This book was released on 1993 with total page 652 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.

Download or read book Processing and Utilization of High sulfur Coals III written by Richard Markuszewski and published by Elsevier Publishing Company. This book was released on 1990 with total page 840 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a collection of peer-reviewed articles providing a summary of the most recent accomplishments by many of the leaders of high-sulfur coal research and development. Improvements in coal cleaning technology by application of either physical, chemical, or biological processes, and new developments in both the froth flotation and oil agglomeration methods of cleaning are reported. Innovative electrostatic and aerodynamic methods are described for cleaning coal, and progress is noted in the development of coal desulfurization by either caustic leaching, oxidative leaching, microbial treatment, or low-temperature pyrolysis. Papers also included in this book concern the capture of sulfur oxides either during or following the combustion of coal; sorbent characterization and the effects of different factors and/or additives on sorbent utilization; the capture of sulfur oxides in various types of combustion systems, including pulverized coal, slagging, fluidized bed and magnetohydrodynamic systems. Recent technical developments are reported for sorbent injection in flue-gas ducts as a means of capturing sulfur oxides.

This book was released on 2012-12-02 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metallurgical Applications of Bacterial Leaching and Related Microbiological Phenomena is a collection of papers presented at the International Symposium on Metallurgical Applications of Bacterial Leaching and Related Microbiological Phenomena, held in New Mexico Institute of Mining & Technology, Socorro, New Mexico on August 3-5, 1977. This book is organized into three sections encompassing 26 chapters. Section I emphasizes the role of microorganisms in the kinetics of leaching and similar metallurgical processes by stimulating a strong interaction between microbiologists and metallurgists. This section also discusses the basic study of microorganisms, in the strictly microbiological aspects of metal extraction and attendant conversion kinetics, and in the practical, engineering aspects of extraction. Section II deals with the microbiological leaching of waste materials, such as fly ash, slags, and jarosite-type leach residues. This section also describes a microbiological process for the recovery of sulfur in its elemental form from sulfate and sulfuric acid-containing aqueous wastes that are to be released in the environment. A microbiological leaching process for the removal of inorganic sulfur contained in coal is also described in this section. Considerable chapters in Section III are devoted to the specific applications of bacterial leaching, the optimization of the leaching conditions, and process optimization based upon economic considerations. This section also examines the advantages of large-scale testing compared with laboratory-testing. Workers in the fields of microbiology, biophysics, biochemistry, mineral processing and preparation, extractive and/or chemical metallurgy, mining engineering, and many related disciplines, including chemical and bioengineering, will find this book invaluable.
