The report gives results of bench-scale development of the Meyers Process (for chemical removal of sulfur from coal) for desulfurization of both fine and coarse coal. More than 90% of the pyrite was removed from run-of-mine (ROM) fine coal and clean coarse coal, and more than 80% of the pyrite from ROM coarse coal. Process improvements were demonstrated involving: increased process slurry solids concentration for higher process throughput (33% w/w); lowered filtration requirements through use of larger top-size fine coal; and generated elemental sulfur removal by vaporization from the coal matrix. Pyrite leaching and reagent regeneration rate expressions were validated. Engineering studies showed that: the process may be engineered in a number of basic designs including simultaneous leach and regeneration, separate leach and regeneration, use of oxygen or air for regeneration, fine or coarse coal processing, and combined with coal cleaning; these process designs lead to stand-alone full capital cost estimates of $30-80/KW of power plant name plate capacity for the various process plant cases. Assuming ROM Coal costs of $0.81/MM Btu, the required market price of the desulfurized coal ranges from $1.14 to $1.32/MM Btu on a utility financed basis and $1.41 to $1.86/MM Btu on an investor financed basis.
