Parametric analysis using AMP and MEA as aqueous solvents for CO2 absorption

A parametric analysis is performed, investigating the effect of inlet gas and liquid flow rates, the initial liquid loading, the type of packing, the initial amine solution concentration and the gas and liquid inlet temperatures on the CO2 absorption efficiency and on the temperature of the liquid getting out the column. The sensitivity analysis shows that the gas flow rate entering the column is the most important factor influencing the CO2 removal efficiency. In addition, inlet liquid temperature has the greater statistical significance on the outlet liquid temperature. The comparison of the two solvents under the same reference conditions shows that MEA is more efficient as solvent for CO2 absorption.
