| Abstract: | In this work, a new model based on the Wilson solution theory was proposed for predicting the solubility of solids in supercritical
fluid (SCF) with and without cosolvent(s) of binary and ternary systems via computation of activity coefficients. For binary
systems the model contains two adjustable parameters, while for ternary systems there are four adjustable parameters. The
calculated results of the proposed model were compared with that of the literature models, and it is shown that the proposed
model is a more accurate one. |
