Abstract: Carbon dioxide (CO 2 ) is one of the greenhouse gases (GHG) that has contributed to the global warming problem.Carbon dioxide is produced in large quantity from coal-fired power plants, iron and steel production, cement production, chemical and petrochemical industries, natural gas purification, and transportation.Some efforts to reduce the CO 2 emissions to the atmosphere are then required.Amine-based absorption may be an option for post-combustion capture.The objective of this study is to measure the effect of promoter addition as well as MDEA concentration for the CO 2 absorption into the aqueous solutions of MDEA to improve its performances, i.e. increasing the absorption rate and the absorption capacity.Absorption of CO 2 in aqueous solutions of MDEA mixtures were measured at 40 °C in a bubble tank reactor.The systems tested were the mixtures of 30 wt% MDEA with 5 and 10 wt% BEA and the mixtures of 40 and 50 wt% MDEA with 6 wt% AEEA.It was found that for MDEA-BEA-H 2 O mixtures, the higher the promoter concentraation the higher the CO 2 absorption rate, while for the MDEA-AEEA-H 2 O mixtures, the higher the MDEA concentration the lower the CO 2 absorption rate.
