This report summarizes the operation and performance of the Kerr-McGee Critical Solvent Deashing (CSD) unit at the six ton-per-day Solvent-Refined-Coal (SRC-I) Pilot Plant in Wilsonville, Alabama. The operating data and test results from June 1978 through March 1981 are detailed and analyzed. Various parameters affecting the performance of the CSD unit were studied. These parameters included: solids withdrawal at the SRC unit dissolver; the SRC unit dissolver pressure and temperature; the SRC unit high pressure separator residence time and temperature in the hot and normal modes of operation; the SRC unit solvent quality, with and without additions of light SRC (LSRC), to the process solvent; and use of selected CSD unit deashing solvents. Various sources of deashing solvent (DAS) losses were identified and the operation of the CSD unit was modified to minimize these losses. The first stage ash processing equipment was modified to produce a free-flowing ash concentrate with a minimal DAS content. Parameters affecting the deashing solvent content in SRC and LSRC products, as well as steam stripping of SRC and LSRC strippers, were investigated.
