摘要：

The mass transfer performance of CO2 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 CO2 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, CO2 loading and liquid flow rate had significant effect on mass transfer performance, but inert gas flow rate has insignificant effect on mass transfer performance. (C) 2013 The Authors.
