In this study, newly measured experimental data of carbon dioxide (CO2) solubilities in aqueous MEA (primary), DIPA (secondary), MDEA (tertiary), AMP (steric hindrance) and their mixture solutions are provided with thermodynamic models, such as Kent Eisenberg, Deshmukh Mather, electrolyte NRTL, electrolyte UNIQUAC models. The solubility measurements were carried out over a wide temperature range (313.15-403.15 K) and at various amine concentration conditions (20, 30, and 40 wt%) with static method. CO2 partial pressure, liquid phase concentrations for all components including carbamates and bicarbonate, pH, the heats of absorption, and cyclic capacity for all amine concentrations, temperatures, and CO2 loading conditions could obtained by using in house model. |
