Absorption rate of carbon dioxide in aqueous solution of methyl-diethanol-amine(MDEA) was determined in a disc column with circulating liquid flow under atmospheric pressure
30-70℃ and 1.75-4.28kmol/m3 of MDEA. The equilibrium data for the system C02-MDEA-H2O were determined by an agitated bubble reactor of self-suction type. All experimental data of absorption rate in this study can be described by an expression of pseudo-first-order rapid reversible reaction
that is in which the apparent activation energy is 33.13 kJ/mol. The effects of temperature
degree of conversion and concentration of aqueous MDEA on absorption rate of carbon dioxide are discussed.
