This report summarizes the progress of the Solvent Refined Coal (SRC) Project for the period March 25, 1979, through June 24, 1979. SRC-I turnaround activities at the Fort Lewis Pilot Plant and several other problems delayed successful startup until April 11. Slurry was injected to the Lummus Deashing Unit for the first time April 12. After approximately eight days, slurry feed was diverted because of indications that solids were accumulating in the settler vessel. The Fort Lewis Pilot Plant was shut down from April 28 to May 12, 1979, while the Lummus Unit settler vessel was hydroblasted. Cleaning of the settler vessel was complete May 10. Modifications to the unit were nearly complete at the end of the reporting period. Slurry feed to the Lummus Unit was reestablished June 15. To date, continuous production of specification product at design rates has not been achieved. One material balance run, MBR 79-1, was completed using Kentucky No. 9/14 coal at proposed design conditions for the SRC-I Demonstration Plant. Process Development Unit P-99 was on-stream for all of the second quarter of 1979, with the exception of a two-week scheduled turn-around. Six different run conditions were tested feeding Pittsburgh Seam coal from the Powhatan No. 5 Mine.
