Abstract |
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) |
