In this thesis, carbon dioxide adsorption performance was performed using methyl di ethanolamine solution in the adsorption column filled with metal pal type packing in both theoretical and laboratory sections. In the laboratory, we measure the amount of carbon dioxide emitted along with the gas flow, the load of carbon dioxide in the amine solution, and finally calculate the volumetric mass transfer coefficient at different flow conditions and the concentration of the amine solution and the concentration of carbon dioxide input. In the simulation part of the rate-based model, here the thermodynamic model of acid gases in Aspen Plus software version 8.3 is used. The effect of various operational parameters such as amine solution flow rate, amine solution concentration and input carbon dioxide concentration on volumetric mass transfer coefficient in laboratory and simulation conditions was discussed. The results showed that in the first part by keeping the concentration of circulating amine solution constant (3 M) and also keeping the concentration of carbon dioxide (3 mol %) constant and increasing the flow rate of amine solution in circulation to 20 kg/h we have a significant increase in volumetric mass transfer coefficient. In the second part, by reducing the flow rate of amine solution in circulation to 13 kg/h and keeping the concentration of amine solution constant as well as the concentration of carbon dioxide input, we see a decrease in volumetric mass transfer coefficient. In the third part, by keeping the concentration and flow rate of the amine solution constant as well as the concentration of carbon dioxide input, we see that the volumetric mass transfer coefficient is constant. In the fourth section, by keeping the concentration and flow rate of the amine solution constant and increasing the concentration of carbon dioxide input from 3 to 15% molar, we see a decrease in volumetric mass transfer coefficient. In the fifth section, as in the third section,
