Title: Solvent refined coal process: operation of the solvent refined coal pilot plant, Wilsonville, Alabama. First quarter report, January-March 1981

Technical Report ·
OSTI ID:6051305

This report summarizes the operating conditions and test results obtained during the first quarter of 1981 at the six ton per day solvent refined coal (SRC-I) pilot plant in Wilsonville, Alabama. The plant operated for approximately two-thirds of the period with a scheduled shutdown, from 22 February to 17 March, accounting for most of the downtime. Kentucky 9 coal from the Fies mine was processed throughout the period. The following potential process improvements and tests were evaluated in the respective process units. SRC Unit: Low severity run tests to evaluate SRC reactor conditions for two-stage liquefaction; process solvent quality studies while simulating demonstration plant conditions with low quality process solvent (anthracene oil); operation of the new, reduced volume and residence time, V103 High Pressure Separator; Evaluation of the hot separator mode of operation; and adjustment of the T102 Vacuum Column operation to determine if it can produce a combined trays 3 and 8 stream that would be an acceptable process solvent (95% boiling at over 450/sup 0/F). CSD Unit: Steam stripping of SRC and LSRC to reduce product-related DAS losses; and ambient and cryogenic SRC sampling comparisons for DAS determination tests. Pressure checking of the hydrotreater unit was completed, and the Dowtherm system was placed in service. Solvent circulation was initiated in the unit as efforts continued to verify equipment performance.
