Economic evaluation of gasification-combined-cycle power plants based on the air-blown KILnGAS process. Final report
This study is an engineering and economic evaluation of the KILnGAS process aimed at: development of overall plant process designs based on a design philosophy consistent with other studies under EPRI RP No. 239-2; preparation of necessary flowsheets, cost estimates and economic evaluations for two gasification combined-cycle (GCC) power plant cases based on the KILnGAS coal gasification process; and continued development of a consistent set of economic evaluations of GCC systems which employ both second-generation gasifiers and power block designs based on currently available combustion turbines having a 2000/sup 0/F firing temperature. Allis-Chalmers Corporation is developing the KILnGAS process to produce low Btu gas from coal by using a rotary, refractory-lined, ported kiln as the gasification reactor. Two base cases (KAAC-C and KAAC-Q) were evaluated. The two designs differ from each other in the manner in which the raw fuel gas is cleaned and cooled. Particulate removal in Case KAAC-C is achieved by a combination of cyclones and venturi scrubbers. In Case KAAC-Q, particulate removal is achieved in a water quench in a venturi scrubber. These designs yield nearly identical clean fuel gas production rates and compositions. Operating costs do not vary much from cyclone designs to water quench design. Five different gasifier configurations (varying the size and number of operating and spare gasifiers) were selected for each cooling design. A number of potential improvements were investigated for the KILnGAS process. Substantial commercial risks are associated with these potential design improvements.
