✦ Synopsis

stirred cell gas-liquid contactor was used to investigate the kinetics of the reaction between carbon dioxide and methyldiethanolamine (MDEA) in aqueous solutions. Experiments were conducted over the temoerature range 15-35°C and for MDEA concentrations from 0.85 to 1.70 g mol/l. The kinetic data supper; a previouslf; proposed mechanism in which MDEA acts as a homogeneous catalyst for CO2 hvdrolvsis. The second-order rate constant was found to have a value of 2.47 l/g mol s at 25"C, in good agreement with existing literature values. The second-order rate constant is correlated well by the Arrhenius expression k, = 8.741 x 10" exp
