Integration methods of a Gas Turbine and a Air Separation Unit have a potential to improve plant performance and cost of IFCC. Several studies on those integrations schemes were carried out. Then some of the methods were accually in commercial plants. Thus paper reviewed the integration schemes of a Gas Turbine and a Air Separation Unit. In order to compare the plant performance of IGCC with each scheme, simulation model was developed for IGCC power cycle with Texaco Quench gasification process. The simulation results showed that the thermal efficiency of the plant was appeared to be the best when all of the air consumption required for Air Separation Unit was supplied from the Gas Turbine and the net plant power output was maximized when 75% of the total ASU an requirement was supplied from Gas Turbine.
