An innovative integrated CCHP system with water scrubbing?based biogas upgrading unit and molten carbonate fuel cell

The main purpose of this study is to develop an integrated structure simultaneous generation electricity and refrigeration as the product hot water a by-product. This proposed consists scrubbing biogas upgrading process, molten carbonate fuel cell (MCFC) unit, gas/steam power (GSP) cycle, absorption (AR) system. In regard, 10.71 kg/s untreated enters system 158,351 kW net produced. Wasted heat utilized generate cooling 253.9 at temperature 243.6 K by applying AR rest used 8.391 byproducts. process integration between different parts has led increase in thermal efficiency whole so that electrical overall efficiencies are 78.68% 79.86%, respectively. investigation exergy demonstrates destruction entire 71,859 kW, which turbine/compressor/pump section with 24,700 (with share 34.37% total) MCFC/reformer 22,285 31.01% have most irreversibility. hybrid 71.06%. Through parametric study, present various conditions assessed. One results outcomes up 83.39% due reduction inlet methane mole content 50%. Rising biogas, although leading more production products, reduces system, including MCFC unit GSP well total efficiency.
