Ionic liquids are 'green' promise solvents in various fields of chemistry and especially in problems related to environmental protection. These solvents are considered non-volatile, their use is far preferable to that of conventional volatile organic solvents. This family of compounds has great potential for gas separation and recovery. The aim of this study is to evaluate the capacity of the PC-SAFT equation of state to represent the systems containing greenhouse gases and ionic liquid. This purely predictive model will be able in the future to predict the phase diagrams of such systems knowing the molecular structure of the ionic liquid. The preliminary results indicate that PC-SAFT is able to represent the properties of pure ionic liquids and binary mixtures {CO2 + ionic liquid}.
