摘要：

The gas-liquid two-phase mass transfer characteristics of CO2 absorption into N-methyldiethanolamine (MDEA) aqueous solution in the microchannel with the array bulges were studied. The influences of gas/liquid flow rate and MDEA concentration on the volumetric mass transfer coefficient kLa, CO2 absorption rate X, pressure drop ΔP and energy consumption ε were studied under slug flow regime. The deformation of slug bubbles due to the squeezing effect of the array bulges promotes the gas-liquid mass transfer efficiency. Compared with non-array bulge microchannel, the array bulge microchannel obviously enhanced CO2absorption rate and has larger volumetric mass transfer coefficient for the same energy consumption. © 2023 Chemical Industry Press.
