Prediction of the solid solubility in supercritical carbon dioxide using a new mixing rule with Lenard-Jones parameters

Author(s): Pouya Mottahedin, Ali Haghighi Asl, Mahmoud Gholam Samani

This study is performed to provide a newmixing rule based on the Lenard- Jones parameters for calculation of the solid solubility in supercritical carbon dioxide. The solubility of solid solutes in supercritical fluid is an important thermo-physical property which is required to be determined. Since generally there are few data about solubility, we need to provide methods to estimate the solubility of solid solutes in supercritical solvents by using limited information. In the current study, the cubic Peng– Robinson (PR) and Soave–Redlich–Kwong (SRK) equations of state are used to estimate the solid solubilities of 18 solutes in supercritical carbon dioxide. This estimation is performed by using four mixing rules which are called the van der waals one fluid rule with one (VDW1) and two (VDW2) adjustable parameters, the covolume dependent (CVD) rule and the newmixing rule. The prediction of the newmixing rule is more accurate than the other mixing rules in the same equations of state for calculating solid solubility in supercritical carbon dioxide and the results of various calculations demonstrate that the proposed mixing rule is in good agreement with the 665 experimental data points that are used in this work.
