RPEDICTION OF SOLUBILITY OF CO2 IN AN IONIC LIQUID WITH PR EOS PAIRED WITH WONG -SANDLER MIXING RULE IN SUPER CRITICAL

Ionic liquids have achieved special attention from the scientific community in recent years and many studies involving different features of properties and applications of Ils have been presented even though the first representative has been known since 1914 ionic liqids have only been investigated as solvents for transition metal catalysis in the past ten years. publications to date show that replacing an organic solvent by an ionic liquid can lead to remarkable improvements in well-known processes in this work we examined the prediction capability of gas liquid equilibrium of CO2 and ILs from the use of the peng-robinson equation of state and UNIFAC activity coefficient model combined with wong sandler mixing rule and then the model compared with experimental data.
