The SASOL test was conducted in order to confirm the operability of the Lurgi process with Western Kentucky coal and determine the preliminary design basis for the Tri-State Synfuels Project. The test plan was structured to optimize design parameters of both the gasification and associated plants and their component units by: demonstrating the need for additional gasifiers over the 36 estimated in the feasibility study; determining the steam requirement, which was about 6% higher than for the feasibility study; confirming the oxygen requirement estimated for the feasibility study; confirming design and performance of the distributor/stirrer to be satisfactory for Illinois Basin type coal; confirming that moderately swelling and strongly caking Illinois Basin coals can be gasified in a Mark IV gasifier fitted with a distributor/stirrer when using a non-caking coal for start-up; determining coal handling and preparation should provide a proper size and minimize fines generation and reject rock material to provide a constant specific gravity coal to gasifier. Confirming that dusty tar injection is feasible up to certain limits and that all the tar injected is gasified; determining that no oil is produced directly from the gasifier; determining that no shift unit is required to adjust the hydrogen-to-carbon monoxide ratio to that required for the input to the Fischer-Tropsch Synthol Units; determining a required increase in frequency of monitoring and quality control measures; and determining that direct use of stripped gas liquor for plant cooling purposes is not practical nor economical due to the excessively high chloride levels.
