چکیده انگلیسی


• A five-parameter empirical model was proposed to correlate solid solubility in SCCO2.
• The proposed model is more accurate than commonly used similar equations.
• The parameters can easily be determined with basic minimization techniques.

The correlation of solute solubility in supercritical fluids is crucial for the development of supercritical applications. Many models have been developed to calculate the solubility of solid compounds. In this work, a new five-parameter empirical model was proposed for correlating solute solubility in supercritical carbon dioxide (SCCO2). The new model successfully correlated solute solubility of 45 compounds (1130 data points) in SCCO2, which were collected from literature published between 2010 and 2015. A comparison of the 14 most common empirical models (Chrastil, Adachi-Lu, del Valle–Aguilera, Sparks, Gordillo, Jouyban, Garlapati-Madras, Ch-Madras, Kumar-Johnston, Méndez Santiago-Teja, Hozhabr, Keshmiri, Khansary) and the proposed model showed that the overall average absolute relative deviation of the proposed model is the lowest (5.16%).
