Post-combustion CO2 capture using alkanolamine is an important method for reducing CO2 emissions into the atmosphere. In this regard and among the alkanolamine solutions, Monoethanolamine (MEA) is the most appropriate solvent. This study presents the sensitivity analysis of the operating parameters which affect the performance of the CO2 capture by MEA, using response surface methodology. Considering to the results, the lean solvent flow rate, amine concentration and stripper pressure affected on the outlet CO2 purity more than the other factors. Also, high energy requirement for solvent regeneration was studied. According to the obtained results, lean solvent flow rate and amine concentration have the greatest effect on the reboiler heat duty.
