Validation of Supercritical Fluid Extraction Model with COMSOL Multiphysics® Software
This paper shows the solution of mathematical model of supercritical fluid extraction process, given by Sovova H., 1994, through COMSOL Multiphysics® software. Sovova et al., 1994 used this model for the supercritical CO2 extraction of grape seed. Extraction was performed with different specific flow rates and grade of grinding. Further Mira et al., 1996 and Mira et al., 1999 validated the same model for the supercritical CO2 extraction of orange peel. These results are plotted with COMSOL Multiphysics® software and compared with the results obtained by Sovova and Mira which gives the successful fit of this mathematical model on the software. A very small average absolute relative deviation (AARD) has been observed between the results of COMSOL Multiphysics® software and the results given in literature.
