Advanced coal conversion process demonstration. Progress report, January 1, 1992--March 31, 1992
This report contains a description of technical progress made on the Advanced Coal Conversion Process Demonstration Project (ACCP). This project will demonstrate an advanced thermal coal drying process coupled with physical cleaning techniques to upgrade high-moisture, low-rank coals to produce a high-quality, low-sulfur fuel. The coal will be processed through two vibrating fluidized bed reactors that will remove chemically bound water, carboxyl groups, and volatile sulfur compounds. After drying, the coal will be put through a deep-bed stratifier cleaning process effect separation of the pyrite rich ash. The process will enhance low-rank western coals, usually with a moisture content of 25--55%, sulfur content of 0.5--1.5%, and heating value of 5500--9000 Btu/lb by producing a stable, upgraded coal product with a moisture content as low as 1%, sulfur content as low as 0.3%, and heating value up to 12,0 00 Btu/lb. The 45 ton/hr unit will be located adjacent to a unit train loadout facility at Western Energy Company`s Rosebud coal mine near the town of Colstrip in southeastern Montana. The demonstration plant is sized at about one-tenth the projected throughput of a multiple processing train commercia; facility. The demonstration drying and cooling equipment is currently commercial size.
