Abstract

In this work, our methodology proposed earlier for the modelling of pervaporation is applied. The modified Rautenbach model is selected again, as an integral part of our methodology. The applicability of the methodology is investigated in the case of ternary mixtures: the connections between the model parameters of the binary and ternary mixtures are studied. For the possibility of comparison the widely investigated water-ethanol as binary and water-ethanol-2-propanol as ternary mixture. involved a PERVAP 2210 PVA/PAN composite membrane are chosen. The parameters of the model are capable to describe the system simultaneously the function of temperature and in the range of feed mixture 0.5-10 wt.% water. For the parameter estimation, the mathematical software GAMS
