This report summarizes the progress of the Solvent Refined Coal (SRC) project by The Pittsburg and Midway Coal Mining Co., under contract with the Department of Energy. The report period covers January 1, 1980 through December 31, 1980. Included herein are summaries of three areas of contract work: the SRC Pilot Plant at Fort Lewis, Washington; the Gulf Science and Technology Company Process Development Unit (P-99) in Harmarville, Pennsylvania; and Research and Development technical support services conducted at Harmarville. The Fort Lewis Pilot Plant conducted five major experimental test programs during 1980, including three test programs on Slurry Preheater B (2'' coil) in both SRC-I and SRC-II modes; SRC-II dissolver backmixing tests, and Lummus Unit performance tests. Process Development Unit P-99 completed 17 runs (Runs P99-63 through P99-79). These runs encompassed a study of the effect of dissolver L/D ratio on yields and a study of operability under low coal feed rate conditions. This work also showed that both Powhatan No. 6 Mine and Ireland Mine coals are desirable feeds for the SRC-II process. R and D Demonstration Plant Technical Support programs made progress during 1980 in the following areas: Prepilot Plant SRC-II Development, SRC-II Reactor System Modeling and Simulation, Process Cost Model, SRC-II Feedstock Screening Methods, Corrosion and Erosion Materials Study, Correlations for prediction of Flow Regimes in Three-Phase Systems of Gas, Coal and Liquid Slurries, Feasibility of Solids Withdrawal from Three-Phase Fluidized Bed Reactors, Heavy Media separation, Coking of SRC-II Process Streams and Catalytic Effect of Iron-Containing Catalysts.
