Modeling and Simulation of Carbon Dioxide Absorption in to MDEA Solution at Packed Column

Abstract

Carbon dioxide (CO2) is a greenhouse gas, a high proportion of gases that affect global warming, and increased concentration of carbon dioxide has led to a rise in surface temperature by 0.30C -0.60C. In this study, the chemical absorption of Carbon dioxide into aqueous MDEA solution has been studied. In this study, the modeling and simulation of the packedcolumnfor CO2 absorption by using MDEA solution was studied using the MATLAB program. This study assumed steady state and non-isothermal. In the system studied the flow rate of gases was 336520 kg / hr, liquid solvent flow rate was 1016300 kg / hr, pressure is 41.06atm, gas and liquid temperature 298ok and 325 ok respectively. It was found that the percentage of absorbed CO2 can be enhanced by increasing the temperature, liquid flow rate, and pressure, decreasing the flow rate of gas.
