A mathematical model was developed to predict the performance of the solvent recovery process in vege-table oil extraction. It consists of a mathematical programming-oriented model for optimizing a biore-finery superstructure. Published experimental data was recompiled related to the PVDF-10SI membrane. For the case study, the mathematical model provides much more conservative design results than when considering just punctual experimental data. To con-centrate miscella from 25% wt to 38% wt of oil, the required membrane area for the mathematical model is 275.22 m2, while the design according to punctual experimental data results in a membrane area of 224.23 m2. Besides, the mathematical model allows evaluating the separation performance of each inter-vening compound through their permeabilities. This is an important contribution since the results obtained using punctual experimental data are not accurate enough for membrane process design in oil desolven-tizing.
