The Electric Power Research Institute (EPRI) has sponsored a series of engineering and economic evaluations for a number of gasification processes, with an emphasis on second-generation technologies. This report presents the results of a detailed evaluation of the Dow Coal Gasification Process applied to a staged, integrated combined-cycle power plant. Dow's process was evaluated because it offers very attractive performance features while retaining the simplicity of a slurry-fed entrained gasifier. Dow has been operating a 24000 t/d commercial scale demonstration unit in Plaquemine, Louisiana since April 1987. The plant feedstock is a low sulfur subbituminous coal, and through October 1989 the plant gasified 800,000 tons of coal. Consecutive 30 and 90 day production records achieved to date are at an 88 and 69 percent capacity factor respectively. Eleven thousand tons of bituminous coal from Southern Utah have also been successfully gasified during March and May 1989 test runs. A plant design and cost estimate was done for a Dow-based, staged construction IGCC plant employing GE 7F combustion turbines located in the Mid-Atlantic region. Primary plant fuels are No. 2 fuel oil during the simple and combined cycle stages and Eastern bituminous coal during the gasification stage. A financial analysis investigating the effects of coal price and capacity factor was also performed. 7 figs., 28 tabs.
