Analysis of Different Proposed Models for Solubility Modeling in upercritical Fluid

The design and development of supercritical extraction processes depend on the ability o model and predict he solubilities of solutes in supercritical solvents. A good solubility speeds up to initial tages of extraction and educes the time of the process to some extent. Therefore, Solubility is an important arameter for obtaining he appropriate extraction in the optimized operational condition. As a result of limitation n conducting xperiments of solubility in supercritical fluid, solubility modeling and improving the existing odels to obtain ore appropriate models has been considered. Generally, there are three approaches of olubility modeling:) A density-based approach, ii) A solubility parameter approach where the SCF is treated s a liquid, iii) An quation of state (EOS) approach where the SCF is treated as a high-pressure gas. In his paper we investigated hese approaches.
