In this study, a thermodynamic model has been used to determine the solubility of carbon dioxide in an aqueous solution which is the combination of methyldiethanolamine (MDEA) and aminoethylethanolamine (AEEA). The physical equilibriums have been considered between the liquid and vapor phases and chemical equilibrium in the liquid phase.

Representation of phase equilibria using a modified form of the extended uniquac model
Thermochimica Acta, 1995Abstract Binary infinite-dilution activity coefficients and LLE data for 14 systems (five aqueous systems, five alcohol + hydrocarbon systems, acetonitrile + n -hexane, and three nitroethane + hydrocarbon systems) are simultaneously correlated with a modification of the extended uniquac model, which also reproduces well binary and ternary VLE data

Isothermal excess Gibbs energy and excess enthalpy data for 29 binary non-ideal systems have been well reproduced by means of the extended UNIQUAC model with temperature-dependent parameters. The temperature dependence of the energy parameters is given by a quadratic function of temperature. Calculated results show that the extended UNIQUAC model works

Modification of the extended uniquac model for correlating quaternary liquid—liquid equilibrium data
Fluid Phase Equilibria, 1990Abstract The extended UNIQUAC model with binary and ternary parameters is modified to include additional quaternary parameters for correlating quaternary liquid—liquid equilibrium data. The quaternary parameters are due to unlike four-body interaction. These parameter-containing terms vanish whenever the quaternary degenerates to a ternary.

Abstract In predicting the liquid-liquid equilibria of ternary mixtures using common excess Gibbs free energy models with only binary parameters, the inaccuracy of prediction has been observed in many cases. A thermodynamic method to overcome this problem is presented here.

Aqueous two phase systems (ATPS), consisting of two incompatible aqueous solutions, are widely used in biological extraction. In recent years, many experimental studies on the phase behavior of ionic liquid(IL)–inorganic salt ATPS systems have been reported but few investigations of the thermodynamics of the IL-based ATPS have been reported.

Thermodynamic modeling of the binary systems Ni(NO3)2–H2O and Ni(NO3)2–H2O and of the ternary system of Fe(NO3)3–Ni(NO3)2–H2O along the 30 °C isotherm are presented. The extended UNIQUAC model was applied for the thermodynamic assessment of the investigated systems, the model parameters were regressed simultaneously using the available databank but ...
