Mathematic modeling of purification of biodiesel with PES polymeric membrane

One of the new separation methods for purifying biodiesel used in recent years, is the membrane separationprocess. In the current research, purification of produced biodiesel was carried out using Polymeric Poly EtherSulfone(PES) based membrane. The prepared PVP membranes was containing 1, 1.5, 2 and 3 wt.% of PVPconcentration with 16 wt.% PES. as additive. Reported experimental determining the membrane flux and separationefficiency (glycerol rejection) membrane was modeled by Maxwell Model . The result , including penetration rate,theory graph and experimental data comparison for biodiesel and glycerin, and error graphs have been explained.Results showed that the experimental data’s have Compatibility with the model and, membrane with 2 percent PVP hasprovided more acceptable results.
