To examine the characteristics of absorption and regeneration, the simultaneous removal efficiency of carbon dioxide/sulfur dioxide (CO2/SO2), the CO2 absorption amount, and the CO2 loading value of an ammonia (NH3) solution added to 2-amino-2-methyl-1-propanol (AMP) were investigated using the continuous absorption and regeneration process. The performances of this system, such as the removal efficiency of CO2 and SO2, absorption amount, and CO2 loading, were evaluated under various operating conditions. Based on the experimental study, the optimum conditions were a liquid circulation rate of 90 mL/min and gas flow rate of 7.5 L/min. The addition of NH3 into aqueous AMP solution increased the absorption rate and loading ratio of CO2 and raised the removal efficiencies of CO2 and SO2 to over 90% and over 98%, respectively.
