Abstract

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^-, CO₃^2-) speciation plots of the 1DEA2P-CO₂-H₂O system were developed in order to further understand the reaction process of 1DEA2P with CO₂.
