The degree of CO 2 absorption by monoethanolamine (MEA) using metal structured packing material, ININ18, was studied. The aqueous solution contained 30 wt‐% MEA in countercurrent with CO 2 flue gas. The capture process was carried out in an absorption column with dimensions 4.0 m in height and 0.3 m in diameter. The mass transfer coefficient and height of mass transfer were evaluated. Results show a volumetric mass transfer coefficient of 3.76 s –1 , a height of mass transfer equivalent unit of 0.317 m, and an absorption efficiency of 90 % from flue gas.
