Carbon Capture and Storage Power Plants : Effects of ASU Integration on IGCC Performance and Gas Turbine Operation

Carbon Capture and Storage (CCS) power plants offer a promising alternative for a considerable reduction of green house gas emissions. The paper exemplifies the modelling and the simulation of an IGCC power plant with CO 2 capture, whereas special focus is laid on the effects that occur by integrating the air separation unit (ASU) within the gas turbine process. The simulation results are presented in terms of technology and their influence on the overall power plant efficiency.
