Abstract: CO2 capture and storage (CCS) from power plants is drawing increasing interest as a potential method for the control of greenhouse gas emissions. A technical parameter study for a CO2 removal plant from flue gas of a gas turbine combined cycle (GTCC) syngas-fired power plant was performed, based on absorption/regeneration process with monoethanolamine (MEA) solutions, using Aspen Plus. The efficiency drop due to CO2 removal plant is approximately 12.9 percentage points, from 55.5% to 42.6%. The research results show that the stripper pressure, MEA inlet flow rate, MEA inlet weight percentage, distillate rate and reflux ratio have great impacts on the performance of the CO2 removal plant.
