Operating conditions and test results obtained at the six-ton-per-day Solvent Refined Coal (SRC) pilot plant in Wilsonville, Alabama are summarized. Two high-volatile bituminous coals were processed. The effects of dissolver volume (space rate), dissolver solids concentration, and feed gas rate on SRC yield and solvent hydrogen-donor quality were determined. A system for withdrawing a portion of the dissolver solids was utilized so that the effects of varying the solids concentration in the dissolver could be investigated. The effects of SRC process conditions and CSD operating conditions on SRC recovery were studied. Recovery of SRC in the Kerr-McGee Critical Solvent Deashing (CSD) unit improved when the dissolver volume was increased. Techniques for cleaning the United States Filter Corporation Vertical-Leaf Filter screens were investigated to provide a basis for redesign of the filter sluicing system. Laboratory-scale filter precoat tests were also made to determine the optimum screen type and mesh.
