    THERMODYNAMIC MODELS Considering water as one of the two components in the super-critical system under investigation, thermodynamic models employed should be capable of describing compounds with association sites at the corresponding high temperatures and pressures. The thermo-dynamic models used in this study are briefly described below. 1. I.D. Watson and J.S.

The mixtures studied also have some special characteristics. For the binary mixtures, CO 2 + capsaicin and CO 2 + β-carotene, the concentration of the solid solutes (capsaicin and β-carotene) in the supercritical solvent (CO 2) is much lower than those for the binary mixtures CO 2 + 2,3DMN and CO 2 + 2,6DMN.

The presence of carbon dioxide in natural gas, synthetic gas and liquid streams has prompted the industrial community to examine the properties of carbon dioxide mixtures with the intent of finding novel methods for removing this acidic impurity.

Carbon dioxide is also of interest to researchers because it possesses a readily accessible critical point. The well-known equation of state Soave-Redlich-Kwong and two of its modifications are applied to describe vapor-liquid equilibrium in binary asymmetric mixtures, which contain supercritical carbon dioxide and a heavy component.

In this case cubic equations of state such as the Peng–Robinson EOS should be used to estimate the VLE of CO 2 and organic solvent systems. During the last few years, the number of studies on thermophysical and thermodynamic properties of pure ILs and their mixtures with molecular solvents has increased significantly [4,].

As for pure ILs, the dependence of the physical properties with temperature and composition is also correlated using empirical by: 6.Thus the high pressure thermodynamics of mixtures is still in a developing state whereas much more research activities have already been dedicated to the high pressure properties of pure compounds, the most recent literature being regularly reported in the Bibliography of High Pressure Research' (for literature up tosee Ref.
