Development of a Novel Fine Coal Cleaning and Dewatering Technology DEVELOPMENT OF A NOVEL FINE COAL CLEANING AND DEWATERING TECHNOLOGY Nikhil Gupta Dissertation submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Mining and Minerals Engineering Gerald H. Luttrell, Chairman Roe-Hoan Yoon, Co-Chairman Gregory T. Adel Stanley C. Suboleski May 6, 2014 Blacksburg, Virginia Keywords: Fine Coal, Dewatering, Processing, Scale-up Copyright © 2014, Nikhil Gupta DEVELOPMENT OF A NOVEL FINE COAL CLEANING AND DEWATERING TECHNOLOGY Nikhil Gupta ABSTRACT The cleaning and dewatering of ultrafine (minus 44 micron) coal slurries is one of the biggest challenges faced by the coal industry. Existing commercial technologies cannot produce sellable products from these ultrafine streams; therefore, the industry is forced to discard this potential energy resource to waste impoundments. This practice also has the potential to create an environmental hazard associated with blackwater pollution. To address these issues, researchers at Virginia Tech have worked over the past decade to develop a novel separation process that simultaneously removes both mineral matter and surface moisture from fine coal particles. The first stage of the process uses immiscible non-polar liquids, such as straight chain hydrocarbons, to selectively agglomerate fine coal particles in an aqueous medium. The agglomerates are then passed through the second stage of processing where mild agitation is used to disperse and fully engulf hydrophobic coal particles into the non-polar liquid and to simultaneously reject any residual water and associated hydrophillic minerals entrapped in the agglomerates. The non-polar liquid, which has a low heat of evaporation, is then recovered by evaporation/condensation and recycled back through the process. The research work described in this document focused on the engineering development of this innovative process using batch laboratory and continuous bench-scale systems. The resulting data was used to design a proof-of- concept (POC) pilot-scale plant that was constructed and successfully demonstrated using a variety of fine coal feedstocks. ACKNOWLEDGEMENTS I would like to express my deepest gratitude to my adviser and my mentor, Dr. Gerald H. Luttrell and Dr. Roe-Hoan Yoon, for their continuous guidance, criticisms and valuable insight throughout this research.

  • THE CHALLENGE of COAL PREPARATION by Anthony G
    THE CHALLENGE OF COAL PREPARATION By Anthony G. Fonseca Director, Coal Utilization, CONSOL Inc. Library, Pennsylvania ABSTRACT About 45-50% of the coal mined in the U.S. passes through coal preparation plants; east of the Mississippi River this number increases to about 75-80%. Although the cost for coal preparation is worthwhile to some, the coal industry faces the challenges of continuing downward pressure on the price of coal and the impact of new environmental regulations. Coal preparation, as commercially practiced today, is an effective process achieving 75-80% ash reduction, 15-80% trace element reduction, and 85-90% Btu recovery; it is less effective for pyrite reduction (35-70%), and on-line operating time (40-60%), and suffers from obsolete control systems. Methods will be discussed for reducing costs of coal preparation and improving the performance of coal preparation plants. Comments are included on equipment selection, especially for –28 mesh coal, and prep plant operation and control practices. Btu recovery ash and pyrite reduction, fines processing including dewatering and slurry fuel use options are emphasized. Trace element removal and expert control systems for maximization of prep plan operation also will be highlighted. INTRODUCTION Coal preparation is the practice whereby raw coal is modified to a more preferred form to enable its utilization. The methods employed to achieve this preferred modification need to be cost-effective, while also being appropriate to the raw coal, the scale of production and the ultimate end user requirements. Since the cost of coal preparation is a measurable part of mine construction and mine operation, any improvement in the process, any efficiency gain or cost reduction obtained, and any improvements in coal product compatibility to end user requirements achieved, are looked on favorably if or when the product is profitably marketed.

  • Introduction to Coal Mining Weir International, Inc
    INTRODUCTION TO COAL MINING WEIR INTERNATIONAL, INC. HISTORY OF COAL IN THE UNITED STATES . Coal was one of man’s earliest sources of heat and light . Coal was first discovered in the United States along the Illinois River in the 1670s . First commercial mining occurred near Richmond, Virginia in 1750 . Between 1850 to 1950, coal was the most important energy fuel in the country . Today, coal accounts for more than half of the electric power generation . Coal is also critical for supplying coke for the nation’s steel industry ORIGIN OF COAL . Most of the coal was formed about 300 million years ago . Remains of vegetation sank to the bottom of swamps, forming a soggy, dense material called peat . Deposits of sand, clay and other mineral matter buried the peat . Increasing pressure from deeper burial and heat gradually transformed the peat into coal . The formation of one foot of coal requires an estimated three to seven feet of compacted plant matter TYPES OF COAL . Coal is classified in four general categories or “ranks”: Anthracite Increasing rank Bituminous Increasing carbon content Sub-bituminous Lignite Increasing heating value . The ranking of coal is based primarily on its carbon content and calorific value . The amount of energy in coal is measured in British Thermal Unit (Btu) per pound . Approximately 90% of the coal in the US is in the bituminous or sub-bituminous category MINING METHODS Surface Mining Underground Mining . Surface mining is: . Underground mining is typically employed where surface mining is not economical Generally the least expensive and most productive mining method to extract coal .

Recycled water generally contains a large quantity of dissolved 19 inorganic electrolytes, which affect coal flotation. This paper reports the conductivity and pH 20 measurements of water in tailings stream of an industrial scale flotation cell covering a period of 21 approximately two years. The different coal seams processed at the site were also compared and the 22 influence the water quality on the overall yield of coal assessed. This study presents the large 23 variation in inorganic content in recycled water observed for a wash plant and determine its possible 24 effect on coal preparation. The maximum daily temperature was found be an important factor 25 controlling the amount of inorganic electrolytes in the water and, very significantly, the water 26 management system implemented. The overall plant performance was not significantly affected by the 27 use of water containing high concentrations of inorganic electrolytes.
