Abstract

In this study, the permeation and separation characteristics during the evapomeation and temperature-difference controlling evapomeation (TDEV) of an isopropyl alcohol/water (IPA/water) azeotrope through poly(vinyl alcohol)/NaY (PVA/NaY) membranes were studied. The effects of operation temperature and feed concentration on the membrane separation factor and flux have been carried out for evapomeation and TDEV. It was observed that the separation factor decreased and the total and partial flux values increased, with increasing the water percentage in the feed concentration and the temperature by using evapomeation and TDEV. The permeation and diffusion activation energies for IPA/water mixture through PVA/NaY membrane were calculated as 23.69 and 41.61 kj/mol, respectively. The results of PVA and PVA/NaY membranes were supported by swelling behaviors. The best separation factor was obtained as 2097.38 using the evaporation method and 2483.75 using the TDEV method.
