In this article the rate of CO2 absorption with using commercial amine solution, AIT600, was measured in a packed-tower of pilot plant in temperature range 323.15-338.15 K and during a 240 min. The input CO2 and amine concentration was 13% (v/v) and 30% (w/w) respectively. The value 3.7 (mole CO2/Lit Solution) was absorbed. The efficiency of carbon dioxide absorption was obtained about 94.21%. The values of rate constant and reaction order were reported. The activation energy and fixed frequency factor were calculated according to the Arrhenius equation.
