Solvent refined coal (SRC) process: operation of solvent refined coal pilot plant, Wilsonville, Alabama. Quarterly technical progress report, July-September 1979

Abstract

This report summarizes the operating data and test results obtaind at the 6 ton per day solvent refined coal (SRC) pilot plant in Wilsonville, Alabama for the third quarter of 1980. Kentucky 9 coal from the Fies mine was processed during the early part of the period (Runs 211 and 212) and again later in the period (Runs 215 through 217). Kentucky 9 coal from the Dotiki mine was fed to the pilot plant during Runs 213 and 214. Coal conversion ranged from 93 to 94.3% of the MAF coal, while the SRC yield ranged from 43 to 81% of the MAF coal. Recovery of SRC from the Critical Solvent Deashing (CSD) unit ranged from 72.7 to 91.3%. The objectives of the runs were: to evaluate the performance of deashing solvent B in the CSD unit in comparison with deashing solvent A (Runs 211 and 212); to investigate the processing of high-chlorine coal and to test the Industrial Filter and Pump Manufacturing Co. (IF) candle filter (Runs 213 and 214); to simulate the design conditions for a 6000 tpd SRC demonstration plant (Run 215); and to evaluate the effects of increasing light SRC addition to the SRC unit with respectmore » to overall unit performance, SRC yield, SRC sulfur content, and solvent balance (Runs 216 and 217).« less
