Koutsonikolas D., Kaldis S., Pantoleontos G., Zaspalis V., Sakellaropoulos G., 2013, Techno-Economic Assessment of Polymeric, Ceramic and Metallic Membranes Integration in an Advanced IGCC Process for H2 Production and CO2 Capture, Chemical Engineering Transactions, 35, 715-720.
In the present study, the integration of membrane technology in an Integrated Gasification Combined Cycle (IGCC) system has been considered, in order to reduce the power plant’s CO2 emissions. In this respect three different membrane materials was examined (polymeric, ceramic and metallic) taking into account the latest advances in membranes’ development. The simulation of membranes separation performance was conducted in a Visual Fortran code and this was incorporated in an Aspen Plus flow diagram for the overall performance assessment. The energy analysis of the alternative cases show that CO2 capture in this hybrid IGCC scheme is technically feasible but with an accompanying energy penalty in the power plant’s output. Taking into account both technical and economic issues the most promising scenario seems to be the integration of a 2-staged ceramic membranes system for H2 separation and CO2 capture.
