Available in PDF, EPUB and Kindle. Book excerpt: The Problems of Sulphur discusses all aspects of the problems associated with sulfur in coal. The book is divided into three parts. Part 1 addresses the forms of sulfur in coal and evaluates processes directed at the chemical removal of sulphur. Part 2 expands on this to look at alternative means of removing sulfur both physically and biologically, sulfur removal during the combustion of coal and flue gas desulfurization processes. Part 3 looks at the role of sulphates in the atmosphere from the points of view of their formation, transport and deposition and of their effects on health, materials and the atmosphere. The book will be of value to engineers, environmentalists, and chemists.

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.

Book excerpt: A process for the removal of divalent organic and inorganic sulfur compounds from coal and other carbonaceous material. A slurry of pulverized carbonaceous material is contacted with an electrophilic oxidant which selectively oxidizes the divalent organic and inorganic compounds to trivalent and tetravalent compounds. The carbonaceous material is then contacted with a molten caustic which dissolves the oxidized sulfur compounds away from the hydrocarbon matrix.

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 1994 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: The initial technical goal in the project was to develop a chemical method for the cost effective removal of both inorganic and organic sulfur from Ohio coals. Verifying and using a process of reacting ethanol vapors with coal under conditions disclosed in U.S. Patent 4,888,029, the immediate technical objectives were to convert a small scale laborative batch process to a larger scale continuous process which can serve as the basis for commercial development of the technology. This involved getting as much information as possible from small scale batch autoclave or fluid bed laboratory reactors for use in pilot plant studies. The laboratory data included material balances on the coal and sulfur, temperature and pressure ranges for the reaction, minimum reaction times at different conditions, the effectiveness of different activators such as oxygen and nitric oxide, the amount and nature of by-products such as sulfur dioxide, hydrogen sulfide and acetaldehyde, the effect of coal particle size on the speed and completeness of the reaction, and the effectiveness of the reaction on different Ohio coals. Because the laboratory experiments using the method disclosed in U.S. 4,888,029 were not successful, the objective for the project was changed to develop a new laboratory process to use ethanol to remove sulfur from coal. Using copper as a catalyst and as an H2S scavenger, a new laboratory procedure to use ethanol to remove sulfur from coal has been developed at Ohio University and a patent application covering this process was filed in March, 1993. The process is based on the use of copper as a catalyst for the dehydrogenation of ethanol to produce nascent hydrogen to remove sulfur from the coal and the use of copper as a scavenger to capture the hydrogen sulfide formed from the sulfur removed from coal.
