Download or read book Ultrasonic Coal Wash for De Ashing and De Sulfurization written by B. Ambedkar and published by Springer Science & Business Media. This book was released on 2012-01-03 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study focuses on the physical aspects of ultrasonic de-ashing and de-sulfurization, such as cavitation, streaming and their combined effects. Ambedkar Balraj proposes an ultrasound-assisted coal particle breakage mechanism and explores aqueous and solvent-based ultrasonic techniques for de-ashing and de-sulfurization. Ambedkar designs a Taguchi L-27 fractional-factorial matrix to assess the individual effects of key process variables. In this volume he also describes process optimization and scale-up strategies. The author provides a mechanism-based model for ultrasonic reagent-based coal de-sulfurization, proposes a flow diagram for ultrasonic methods of high-throughput coal-wash and discusses the benefits of ultrasonic coal-wash. Coal will continue to be a major fuel source for the foreseeable future and this study helps improve its use by minimising ash and sulfur impurities.

This book was released on 2013-11-11 with total page 672 pages. Available in PDF, EPUB and Kindle. Book excerpt: Filling the need for new and improved energy sources is an area where societal effects of science and technology will surely increase. The editors and authors have attempted in this volume to present the most current work on the science and technology of coal and coal utilization. Serious disagreement exists on several key issues such as carbon dioxide release and acid rain. At the same time, however, coal is the world's most abundant fossil fuel and will have to be used to supply the world's energy needs for the next several decades. The 1979 National Research Council Report, "En ergy in Transition: 1985-2010," has estimated that the United States alone may go from a 1979 coal consumption of 14 QUADS per annum (approximately 750 million tons per year) to approximately 40-50 QUADS per annum (approximately 2 billion tons per year) by the year 2010. If this scale of coal utilization is to become a reality, a significant level of research and development will be necessary to establish advanced process technologies and to improve related areas such as materials and instrumentation. The editors hope that this volume will allow a technically educated person to become aware of the several aspects of coal utilization, from characterization of coal itself to the processes of coal utilization.

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.

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.
