The general separation processes for liquid mixtures need the energy consumed and causes of primary cost. The pervaporation separation process could be regarded as the energy saving process[1]. In this study, it is introduced that the preferential isopropyl alcohol separation from the aqueous feed was carried out using the composite membranes according to the operating conditions, such as, the operating temperature, feed concentration etc. And the commercial scale module was prepared and tested for the long-term period, and finally the stabilized and consistent results of both permeability and selectivity were obtained.
