Abstract

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.
