A Study on Design and Cost Analysis of a Prototype Coal Cleaning Plant. Supplement

摘要

Four alternate methods suggested in the report which this one supplements are explained in detail. The most economical method to determine the reduction of sulfur from a given raw coal is based on beneficiation equipment currently used by coal washing contractors; it involves extensive laboratory testing from suitable raw coal samples. If carried out in one of the existing government laboratories it would involve no capital investment; operating costs would also be small. In case a plant is desired to demonstrate in actual practice the reduction of sulfur as well as to generate data for a given coal, it will be of substantial value both from a scientific and commercial standpoint to build a full scale commercial plant. Being capable of operation at a full commercial rate, this facility would be able to provide an adequate return on the total investment. It would be an added advantage if cooperation could be obtained from a large coal company to run the plant. (Author)
