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 Removal of Organic and Inorganic Sulfur from Ohio Coal by Combined Physical and Chemical Process. Final Report written by and published by . This book was released on 1989 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project consisted of three sections. In the first part, the physical cleaning of Ohio coal by selective flocculation of ultrafine slurry was considered. In the second part, the mild oxidation process for removal of pyritic and organic sulfur.was investigated. Finally, in-the third part, the combined effects of these processes were studied. The physical cleaning and desulfurization of Ohio coal was achieved using selective flocculation of ultrafine coal slurry in conjunction with froth flotation as flocs separation method. The finely disseminated pyrite particles in Ohio coals, in particular Pittsburgh No. 8 seam, make it necessary to use ultrafine ( -500 mesh) grinding to liberate the pyrite particles. Experiments were performed to identify the ''optimum'' operating conditions for selective flocculation process. The results indicated that the use of a totally hydrophobic flocculant (FR-7A) yielded the lowest levels of mineral matters and total sulfur contents. The use of a selective dispersant (PAAX) increased the rejection of pyritic sulfur further. In addition, different methods of floc separation techniques were tested. It was found that froth flotation system was the most efficient method for separation of small coal flocs.

Book excerpt: Sulfur removal from coal before combustion is of considerable interest to avoid emission of oxides of sulfur(SOx). Chemical and physical methods have been developed for removing the inorganic sulfur component in coal. This component is generally associated with pyrites(FeS2). However, no commercial methods have been developed for the removal of the organic sulfur conponent. This study describes microbial methods for removing organically bound sulfur from coal. The specific goals of this study were to ascertain whether a robust biologically active population such as activated sludge biomass can remove organic sulfur from coal and to devise sulfur analytical methods that are less cumbersome than the accepted standards for screening research results. Dibenzothiophene is used in isolating microorganisms that use sulfur as the sole source for growth. It was found that about 55% sulfur can be removed by activated sludge in shaker flasks from a coal which was previously treated to remove inorganic sulfur(IBC-108). A no cycling leaching reactor with activated sludge removed 50% sulfur from the same type of coal. Almost 72% sulfur is removed by A-i, S-Dl, T3-2 and Ar-i mixed cultures. It was also found that about 25 to 29% sulfur can be removed by different cultures from a commercially prepared washed coal in which the pyritic and organic sulfur have not been altered. The application of ion-chromatography and atomic spectrometry in analyzing sulfate, pyritic sulfur, organic sulfur and total sulfur following ASTM extraction can achieve easier and quicker sulfur determinations without sacrificing accuracy and reproducibility.

Download or read book Processing and Utilization of High-sulfur Coals IV written by Patrick R. Dugan and published by Elsevier Publishing Company. 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.
