Analysis of Different Proposed Models for Solubility Modeling in Supercritical Fluid

The design and development of supercritical extraction processes depend on the ability to model and predict the solubilities of solutes in supercritical solvents. A good solubility speeds up to initial stages of extraction and reduces the time of the process to some extent. Therefore, Solubility is an important parameter for obtaining the appropriate extraction in the optimized operational condition. As a result of limitation in conducting experiments of solubility in supercritical fluid, solubility modeling and improving the existing models to obtain more appropriate models has been considered. Generally, there are three approaches of solubility modeling: i) A density-based approach, ii) A solubility parameter approach where the SCF is treated as a liquid, iii) An equation of state (EOS) approach where the SCF is treated as a high-pressure gas. In this paper we investigated these approaches
