The kinetics of the reaction of CO2 with aqueous formulated solutions containing 50 wt % N-methyl-2-pyrrolidone (NMP) and 10 wt % diethylene glycol (DEG) (relative to water) and various amounts of monoethanolamine (MEA) were studied in a stirred cell reactor with an undisturbed gas-liquid interface at 303 K, using the fall in pressure technique. The MEA concentration in the formulated solution was varied in the range 1.5-2.5 kmol m(-3). The densities and viscosities of these amine solutions were measured. The physical properties such as solubility and diffusivity Of CO2 in these amine solutions were estimated using N2O analogy. The overall reaction could be regarded as a reaction between CO2 and MEA in parallel with the reaction of CO2 with NMP.
