Process economics for Coalcon's clean boiler fuels from coal demonstration plant show that the final minimum selling prices of the fuels from this process vary from $2.07 to $2.80/million Btu. The higher figure was derived using the discounted cash flow method, while the lower figure assumes a debt:equity method of financing. The conceptual design for the plant is divided into five main areas: coal preparation, hydrocarbonization reactor, reactor product cooling and liquids separation, gas processing, and hydrogen generation. Ancillary equipment includes char combustion/steam generation, sulfur processing, pollution abatement, and utilities (power, cooling water, etc.). The demonstration plant will operate at over 2,700 ton/day of coal feed and will be tested using Pittsburg No. 8, Illinois No. 6, and Western Kentucky No. 11 coals. The coal will be washed and crushed to about 1/sup 1///sub 2/ x 0 and be stored in a stockpile. The crushed coal will then be ground and dried to about 1% moisture. The final coal size will be 60 to 325-mesh. Next, the coal is heated in an entrained bed heater using oxygen-free flue gas to about 325/sup 0/C and pressurized to about 260 lb./sq. in. gauge above the reactor pressure using a lock-hopper system. The hot pressurized coal is than dumped into a holding vessel before being introduced into the reactor. The coal is fed into the hydrocarbonization reactor pneumatically using recycle hydrogen.
