| الملخص | In this work, the CO2 equilibrium solubility in 2 M 1-diethylamino-2-propanol (1DEA2P) solution were determined as function of temperature (in the range of 298-333K), and CO2 partial pressure (in the range of 8-101 kPa). The modified Li-shen K2 correlation model was also developed and used to predicate the CO2 equilibrium solubility in 1DEA2P solution. with an excellent ADD of 3.4%. The heat of CO2 absorption in 1DEA2P solution estimated using Gibbs-Helmholtz equation was found to be -45.7 kJ/mol. In addition, the ion (1DEA2P, 1DEA2PH+, HCO3-, CO32-) speciation plots of the 1DEA2P-CO2-H2O system were developed in order to further understand the reaction process of 1DEA2P with CO2.
