“…In the pervapour ation method, transport takes place in a three-step sequence: absorption into the membrane, diffusion through the membrane and desorption from the membrane to the vapour phase (Fan et al, 2003). Also with this method, since the membrane is in direct contact with the feed solution, there are disadvantages such as membrane swelling or shrinkage, which cause a decrease in the separation factor (Uragami, 2017).…”

This study investigated 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. The effects of the operational temperature and the feed concentration on the membrane separation factor and flux values were investigated for evapomeation and TDEV. The permeation and diffusion activation energies for an IPA/water mixture through a PVA/NaY membrane were calculated to be 23.69 and 41.61 kJ/mol, respectively. The results for the PVA and PVA/NaY membranes were supported by swelling behaviors. The best separation factor obtained was 2097.38 using the evapomeation method and 2483.75 using the TDEV method.
