Abstract:

In this work, the effects of permeate pressure and feed flow rate on the performance of a composite polyvinyl alcohol (PVA) membrane in the removal of benzene from gasoline by pervaporation (PV) were evaluated. The results indicate the remarkable effect of permeate pressure on membrane performance as reducing permeate pressure (higher vacuum) from ۳۰ to ۳ mmHg causes the total flux to increase from ۶.۶ to ۵۱.۷ g/hrm۲ and from ۱۲.۲ to ۷۹ g/hrm۲ at ۲۵ and ۳۵ °C respectively. Furthermore, increasing feed flow rate enhances total flux and diminishes the amount of benzene in retentate (product) only below ۱۰۰۰ ml/min and has a negligible effect at higher flow rates.
