Download or read book Coal Flotation and Fine Coal Utilization written by J. Laskowski and published by Elsevier. This book was released on 2001-07-04 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: To stay profitable while complying with environmental regulations requires that the coal industry not only improve fine coal recovery but also finds better ways for its utilization. This is the first monograph on the processing of fine coal which recognizes that all unit operations that handle fine coal depend on coal surface properties, and which in one single volume provides a comprehensive introduction to coal surface chemistry, using it rigorously in treating coal flotation fundamentals and engineering, fine coal manipulation, pelletization and briquetting, and coal-water slurries. Readers involved in mineral processing, chemical engineering, mining and metallurgical engineering; technical personnel working for reagent suppliers; and scientists researching the field of coal surface chemistry, flotation and fine coal utilization will find this volume of great interest.

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.

Download or read book A Novel Technique for Evaluating Cleaned Fine and Ultrafine Coal written by and published by . This book was released on 1991 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a standard industrial practice all commercially cleaned coals are evaluated by washability analysis to predict their cleaning potential. The results of this analysis are so important that coal washability is a major factor in deciding to purchase and develop coal holdings. However, washability analysis are at present limited to coal particle sizes of greater than -28 mesh (0.6 mm). Coal particles smaller than this limit do separate well in the standard sink-float process used in the washability tests. The increasing demand for cleaner coals requires that coals be crushed to fine ( -100 mesh - 0.15 mm) and ultrafine ( -325 mesh - 0.045 mm) sizes to liberate more of the fine-grained mineral matter including pyrite. However, such small coal particles can not be analyzed in the standard washability analysis. The purpose of this study is to develop a washability analysis system for fine and ultrafine coal particles using Density Gradient Centrifugation (DGC) and Thermal Gravimetric Analysis (TGA) techniques. The unique advantages of this proposed technique is that is provides a means to obtain usable washability curves on fine and ultrafine coal samples. The DGC technique will produce a large number of density fractions in a single run and, thus, is much faster and more efficient that normal washability analysis. During this quarter all of the samples to be used in this study have been ordered from the Illinois Basin Coal Sample Program and the initial results for one sample have been examined.
