Abstract Some experiments were conducted to investigate the effect of addition of adipic acid on absorption and desorption processes of CO in MEA solutions. For the desorption of CO in MEA with concentration of 0.4 mol · L, the energy consumption was decreased by addition of adipic acid, and the desorption rate was improved. The absorption capacity of lean solvents was decreased in the second absorption processes, but only a small difference (< 7%) was observed between the amounts of CO absorbed in lean solvents with/without addition of adipic acid. When the same amount of adipic acid was added directly into the MEA solvent at the beginning of absorption process, the absorption capacity for CO decreased. For the MEA solutions with higher concentrations (7 mol · L and 12 mol · L), and the decreases in the absorption capacity resulted from the addition of adipic acid was less as the concentration increased, the energy consumption for desorption decreased considerably, and the desorption rate increased. By comparison of the effect on absorption and desorption of CO, it is concluded that addition of adipic acid is effective to reduce the energy requirement in solvent absorption of CO.
