Site confirmation report. Preliminary design and assessment of a 12,500 BPD coal-to-methanol-to-gasoline plant. [Grace C-M-G Plant, Henderson County, Kentucky]
In January 1982, it was agreed to modify the Cooperative Agreement between W.R. Grace and Co. (Grace) and the US Department of Energy calling for the design and assessment of a coal-to-methanol-to-gasoline plant (Gasoline Plant) which would produce 50,000 barrels per day (BPD) of gasoline from high-sulfur agglomerating coal to include the preparation of a capital and operating cost estimate for a 12,500 BPD Gasoline Plant. The smaller 12,500 BPD Gasoline Plant uses the same basic equipment and processes as the larger plant. The major changes occur in process units after methanol synthesis, where two smaller sulfur recovery and removal units, one methanol-to-gasoline unit, a smaller fractionation unit, and smaller heavy gasoline treating and alkylation units are required. Thus, all processes used in the larger plant are used in the smaller plant. Products produced are identical but less in quantity. The coal pile is reduced considerably in size, and the concept of operation changed. The capacity of the steam generating facilities is reduced, but not by a factor of four, because sufficient steam is still required to start up the air separation plants. There are fewer air separation plants, but each still has a capacity of 2500 TPD. However, instead of three steam generating units each capable of generating 600,000 lb/hr of steam, fewer units of somewhat smaller capacity are used in the 12,500 BPD Gasoline Plant. Consequently, the reduction in scale does not influence the processes used to remove particulates and SO/sub x/ from flue gas. Fewer cooling towers, or towers of reduced capacity, are required instead of the four necessary for the 50,000 BPD Gasoline Plant.
