Palm pressed fibre a by-product from the processing of crude palm oil contains about 5-8 residual oil (on dry basis). The oil contains a high amount of minor components such as phospholipids carotenes and vitamin E. This study investigates the ability of polymeric membranes to remove phospholipid from residual palm fibre oil/hexane miscella. The performance of 10 kDa polyethersulphone (PES) 20 kDa PES and 30 kDa polyvinylidene fluoride (PVDF) membranes were evaluated. A detailed evaluation on 30 kDa PVDF showed that permeate flux increases with the increase of operating pressure temperature and agitation speed. Increasing operating pressure from 2 to 6 bar with a temperature of 40C and speed of 300 rpm resulted in the retention of phospholipids from 81 to 95. The resistance of the membrane due to concentration polarisation ranged from 30.6 to 97.0 x 1012 m-1 which gave 79 “ 84 of total resistance values indicating significant influence on the permeate flux. A complete 23 experimental design indicated statistically that the increased pressure temperature and agitation speed resulted in a higher permeate flux. An increase in pressure and agitation speed also increased the retention of phospholipid. However the regression model obtained from this study showed that the temperature had a negative effect on the retention of phospholipid.

Abstract

Palm pressed fibre a by-product from the processing of crude palm oil contains about 5-8 residual oil (on dry basis). The oil contains a high amount of minor components such as phospholipids carotenes and vitamin E. This study investigates the ability of polymeric membranes to remove phospholipid from residual palm fibre oil/hexane miscella. The performance of 10 kDa polyethersulphone (PES) 20 kDa PES and 30 kDa polyvinylidene fluoride (PVDF) membranes were evaluated. A detailed evaluation on 30 kDa PVDF showed that permeate flux increases with the increase of operating pressure temperature and agitation speed. Increasing operating pressure from 2 to 6 bar with a temperature of 40C and speed of 300 rpm resulted in the retention of phospholipids from 81 to 95. The resistance of the membrane due to concentration polarisation ranged from 30.6 to 97.0 x 1012 m-1 which gave 79 “ 84 of total resistance values indicating significant influence on the permeate flux. A complete 23 experimental design indicated statistically that the increased pressure temperature and agitation speed resulted in a higher permeate flux. An increase in pressure and agitation speed also increased the retention of phospholipid. However the regression model obtained from this study showed that the temperature had a negative effect on the retention of phospholipid.
