This report presents operating conditions and test results at the Solvent Refined Coal (SRC-I) pilot plant in Wilsonville, Alabama. Two coals from the Kentucky 9 seam (Lafayette mine and Dotiki mine) were processed. Hydrogen consumption, coal conversion and SRC yield were comparable when these coals were tested under similar conditions. Process solvent quality improved after the feed was switched from Lafayette to Dotiki coal. A vertical-leaf filter, manufactured by the United States Filter Corporation (USF), was used for solids separation during most of the Lafayette coal operations. The Kerr-McGee Critical Solvent Deashing (CSD) unit, which had been shut down for modifications since late 1979, was returned to service near the end of the Lafayette coal tests and remained on-stream during Dotiki coal processing. Using solution-annealed screens in the USF filter has eliminated the corrosion-related screen failures previously encountered. Cresol-insoluble material was very low, but ash in the filtered SRC product consistently exceeded the 0.16 wt % specification. The high-ash SRC product appears to have resulted from the presence of sodium carbonate, which was added to the coal slurry to prevent corrosion in the solvent recovery system. Recovery of SRC in the CSD unit ranged from 78 to 82 wt %. Deashing solvent losses averaged 4.9 wt % of the CSD feed.
