The effects of operating parameters such as feed temperature and permeate-side pressure on the performance of a commercial PVA membrane in the dehydration of toluene by a pervaporation (PV) membrane system is studied in the present work. The results obtained indicate that increasing temperature in the range of 40 to 70 °C and reducing permeate pressure in the range of 1 to 10 mmHg increase membrane flux and selectivity, which consequently leads to the considerable modification of membranedoi:10.22078/jpst.2013.9 doaj:115974f3661f4c3b8f1baabf729e58f0 fatcat:y6thsm6shfba3oho6jw3bwag2a
