%X The separating of carbon dioxide gas is the main processes in gas treatment. Often, in order to separate carbon dioxide from the natural gas ow, a method of absorption, along with the chemical reaction, by Alkanolamine solutions, is used. In this research, the thermodynamic model of carbon dioxide gas solubility in an aqueous mixture of MEA and MDEA has been studied and the model parameters are given. In this model, for the calculation of a short range term, the UNIQUACNRF model is used as a Non-electrolyte model and, for stating a long range term, the model of Pitzer-Debye- Huckel has been used. This model is extended at different temperatures and the interaction parameters for the mixture of MDEA-MEA-H2O-CO2 were optimized. The results obtained from this model, in comparison with the work of Li-Mather, are more accurate.
