Abstract
The mass transfer performance of CO 2 absorption into three solvents (i.e., 5 M MEA in methanol, 5 M MEA in 1:1 water-methanol volume ratio, and 5 M MEA aqueous solutions) in an absorption column packed with DX structured packing at various CO 2 loading, liquid flow rate, and inert gas flow rate. The mass transfer performance was evaluated in terms of volumetric overall mass transfer coefficient (K G a v ) and mass flux. The results showed that 5 M MEA in methanol has higher mass transfer performance than those of 5 M MEA in 1:1 water-methanol volume ratio and 5 M MEA aqueous solutions, respectively. In addition, CO 2 loading and liquid flow rate had significant effect on mass transfer performance, but inert gas flow rate has insignificant effect on mass transfer performance.
