Solubility, Kinetics, Absorption Heat and Mass Transfer Studies of CO2 Absorption into Aqueous Solution of 1-Dimethylamino-2-propanol☆

Abstract In this work, the performance of CO 2 absorption into aqueous 1-dimethylamino-2-propanol (1DMA2P) solution was investigated for possible CO 2 absorption application and compared with those of MEA and MDEA. The CO 2 absorption performance was presented in terms of equilibrium solubility, absorption rate, absorption heat, and overall mass transfer coefficient (K G a v ). The results show that 1DMA2P has a higher solubility and a lower absorption heat than those of MEA and MDEA, a faster absorption rate and a higher K G a v than that of MDEA, but a lower K G a v than that of MEA. Due to the high performance of the 1DMA2P, it can be considered to be a promising alternative solvent for CO 2 capture.
