Removal of free fatty acid from crude palm oil using organic solvent nanofiltration (OSN)

Removal of free fatty acid from crude palm oil using organic solvent nanofiltration (OSN)

The high content of free fatty acid (FFA) in crude palm oil has become a challenge in refining process due to refining losses and possible bleachability problems. Nowadays, alkaline and distillation approaches are widely used in industry to remove FFA but certain factors such as high energy consumpt...
