Operating conditions and experimental results obtained during the second quarter of 1979 at the Solvent Refined Coal (SRC) pilot plant in Wilsonville, Alabama, are presented and discussed. Kentucky 9 coal obtained from the Pyro Mining Company and the Lafayette Coal Company was processed. Material balances were completed for four of the six runs attempted during the quarter. Tests were conducted in the following operating modes: Using 75% of the dissolver volume, bypassing the dissolver completely, introducing part of the feed gas after the slurry preheater, and withdrawing slurry from the dissolver bottoms. The Kerr-McGee Critical Solvent Deashing (CSD) unit produced SRC containing 0.01 to 0.87% ash when operating at feed rates up to 350 lb/h. The median daily ash level in the product was 0.13%; and total deashing solvent losses averaged 7.1% of the feed. Recovery of SRC ranged from 75.9 to 82.8%.
