Texaco environmental tests on a 165-tpd Texaco gasifier. Final report

Technical Report ·
OSTI ID:5299726
In support of the commercial development of the Texaco Coal Gasification Process, the Electric Power Research Institute has sponsored studies to evaluate environmental characteristics of the process. The first tests were conducted at Texaco's Montebello Research Laboratory Pilot Plant (15 tons per day). To verify the favorable data from these tests, EPRI made arrangements for a run on Illinois No. 6 coal at the semi-works (165 tons per day) coal gasification plant of Ruhrchemie in Oberhausen, West Germany. Texaco obtained samples, arranged for analyses, and prepared this report covering the environmental aspects of that run. The test run at Ruhrchemie has confirmed that the Texaco Coal Gasification Process is an environmentally sound method of utilizing coal. Most of the sulfur compounds in the coal are converted to hydrogen sulfide, which can be removed from the gas by an acid gas scrubbing process, such as Selexol. This eliminates the need for stack gas scrubbing to meet SO/sub 2/ emission regulations when the treated gas is used as a boiler or turbine fuel. Volatile metals, particulate matter, and organic compounds other than methane and formate are present at very low levels in the gas. However, the mass balance for some volatile elements has not been closed. The process effluent water composition is such that available water treatment technology will significantly reduce contaminant levels. The slag would be classified as a nonhazardous waste on the basis of EPA RCRA regulations. 1 figure, 47 tables.
