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. 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. At the Fort Lewis Pilot Plant, testing of the Lummus Unit was completed in January and plant operation was switched from the SRC-I mode to the SRC-II mode. Installation of the new 1-1/2'' coil for Preheater B was also completed and Preheater B was recommissioned January 21. Testing of the preheater resumed in February and was completed in March. The plant was shut down March 26 for the annual shutdown. Process Development Unit P-99 completed three runs (Runs P99-80, -81 and -82) during the First Quarter of 1981. These runs were part of a study to investigate the effect of dissolver L/D ratio and concentration of 550/sup 0/F- distillate in the feed slurry on yields. The butane scrubber was successfully started up in March. Research and Development technical support programs made progress 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 Compounds. Seven appendices have been entered individually into ERA and EDB.
