This report summarizes the progress of the Solvent Refined Coal project by the Pittsburg and Midway Coal Mining Co. for the Department of Energy for the period June 25, 1979 through September 30, 1979. Except for brief periods, the Fort Lewis Pilot Plant continued to operate in the SRC-I mode and to process Kentucky No. 9 and 14 coal from Pittsburg and Midway's Colonial Mine. Testing of the Lummus Antisolvent Deashing Unit resumed July 21 and continued to operate through August 20, but prolonged steady state operation was not achieved. The Pilot Plant was shutdown August 25 to complete the installation of the new preheater in Area 02, for annual inspection, for conversion to SRC-II mode operation, and for extensive modifications to Areas 01 and 04. Operation is scheduled to resume the week of October 12 in the SRC-II mode to test the new Area 02 preheater. Process Development Unit P-99 was down during July for the annual summer trunaround. Returning to lined out conditions on coal after the turnaround was delayed by a series of equipment failures. After these problems were overcome, two runs (Runs 56 and 57) were completed. These runs, made on Powhatan No. 5 Mine coal, showed that C/sub 5/-900/sup 0/F distillate yield increased about 5% as pressure was increased from 2000 to 2500 psig.
