Operating conditions and test results obtained at the six-ton-per-day Solvent Refined Coal (SRC-I) pilot plant in Wilsonville, Alabama, during 1979 are summarized. The plant was operated for a total of 284 days, or 78% of the year. Three coals were processed: Kentucky 6 and 11 and Kentucky 9 from the Pyro mine, and Kentucky 9 from the Lafayette mine. The coal space rate ranged between 25 and 50 lb/h-ft/sup 3/, dissolver conditions ranged between 1700 and 2100 psig at 825/sup 0/F, and gas feed rates ranged from 6000 to 12,000 scfh. Conversion to cresol soluble organics ranged from 90 to 95 wt % of the MAF coal, while hydrogen consumption ranged from 1.3 to 2.7 wt % and SRC yield ranged from 45 to 75 wt % of the MAF coal. Mineral separation techniques studied included Critical Solvent Deashing (CSD) and vertical leaf filtration. SRC recoveries at the CSD unit ranged from 65 to 85 wt % of SRC in the CSD feed. Filtration rates of 4.4 gal/h-ft/sup 2/ of filter area were demonstrated with precoat. However, operation without precoat was unsuccessful.
