dc.description.abstract A study of the performance of the absorption of CO2 in an aqueous solution of a primary alkanolamine was evaluated experimentally in a lab-scale absorber packed with a high efficiency DX structured packing and compared with that in amino alcohol, 4-diethylamino-2-butanol (DEAB), which has been developed as an effective post combustion CO2 capture solvent. As well, the performance of CO2 absorption in a conventional tertiary amine, methyldiethanolamine (MDEA), and aqueous mixed MDEA/MEA solutions with concentration weight ratios of 27/03, 25/05, and 23/07. The results show that the new synthesized, in-house developed chemical solvent (DEAB) had higher energy efficiency for regeneration, higher absorption capacity and higher cyclic capacity for CO2 removal with higher removal efficiency for CO2 along the height of the column than MDEA. An empirical correlation for the mass transfer coefficient for the CO2-DEAB system has been developed as a function of the process parameters. The results conducted on the mixed aqueous MDEA/MEA solutions showed higher CO2 removal efficiency along the height of the column and excellent overall mass transfer coefficient (KGav) values as the MEA/MDEA ratio increases. However, in terms of both chemical reactivity and cyclic capacity, the concentration ratio of 23/07 MDEA/MEA showed a superior performance. en_US
