ABSTRACT:
Power is developed by an expansion turbine in which the working fluid is a gaseous mixture comprising all of the hot raw gas stream leaving an unpacked partial oxidation gas generator, after removing if present a portion of the entrained solids, in admixture with a temperature moderating stream. A molal increase is associated with the partial oxidation process. Power is obtained from this molal increase in addition to the power obtained from the elevated pressure and sensible heat in the hot raw partial oxidation product gas. The temperature moderating stream may comprise a recycle portion of the turbine exhaust gas stream after being cooled, cleaned, optionally water-gas shifted or purified, or both, and recompressed. Alternatively, the recycle gas stream may be mixed with water, steam, or both. In one embodiment the temperature moderating stream comprises liquid water or condensate produced in the process. Auxiliary gas compressors for recompressing said recycle gas, and optionally for compressing a free-oxygen containing gas for use in the gas generation zone may be driven by said expansion turbine. Similarly, an electric generator may be coupled to the turbine shaft.
