CO_2 Absorption by MDEA Solutions from Flue Gas

With the guidance of the reaction mechanism of CO2 absorption by MDEA,the ab sorption rate and the capacity of CO2 from industral flue gas were investigated,which influenced by MDEA concentration,the reaction temperature and the gas flow.The absorption rate of 0.43 mmol/s and the capacity of CO2 of 16.05 mmol/mL could be obtained under the conditions that the concentra tion of MDEA was 0.03 mol/L,the gas flow was 46.6 mL/min and the reaction temperature was 22℃.The experiment results could provide theoretical foundation for further research on dynamical meth od of absorption of CO2.
