abstract = "This work provides new data for carbon dioxide (CO2) absorption into phase change solvent systems consisting of an aqueous solution of 2-(diethylamino)ethanol (DEEA) and 3-(methylamino)propylamine (MAPA). The variables related to CO2 absorption are studied and a Lewis cell type apparatus is taken into use. The latter was first validated with experiments of CO2 absorption into aqueous methyl diethanolamine (MDEA) solutions. Experiments are carried out for the determination of apparent kinetic absorption constant and absorption rate of CO2 for aqueous DEEA/MAPA mixtures. The determined kinetic constants (0.008-0.007 mol·(m3·s)-1 for MAPA/DEEA between 308 and 318 K and 0.0184-0.0022 m3·(mol·s)-1 for MDEA between 296 and 318 K) are compared to the literature where available. The phenomena related to phase change solvent absorption are carefully studied. A relation between total CO2 loading and absorption rate is observed, and reasons behind the dependency and the phenomena are analyzed.",
