The Light Integrated Coal Gasification Fuel Cell (L-IGFC) plant technology is one of the most promising technologies in the coal utilization for power generation. It could reach maximum efficiency 60.32% in LHV when the operating pressure and temperature of SOFC are 3 atm and 850 C, respectively. However, this plant has not equipped yet with CO2 capture technology to mitigate CO2 emission. In another issue, the integration of CO2 capture technology in a plant system significantly could reduce the total system efficiency. Therefore, in this study, a membrane-based CO2 capture technology which is equipped with heat recovery systems is established to remove CO2 before entering into the SOFC module. The total efficiency of the proposed system is 62.50% which is 2.18 points higher than the reference system without CO2 capture. Thus, the L-IGFC plant integrated with membrane-based CO2 capture technology could avoid the efficiency penalty.
