In this work, the performance of CO2 absorption into aqueous 1-dimethylamino-2-propanol (1DMA2P) solution was investigated for possible CO2 absorption application and compared with those of MEA and MDEA. The CO2 absorption performance was presented in terms of equilibrium solubility, absorption rate, absorption heat, and overall mass transfer coefficient (KGav). 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 KGav than that of MDEA, but a lower KGav than that of MEA. Due to the high performance of the 1DMA2P, it can be considered to be a promising alternative solvent for CO2 capture.
