High FFA Oils such on Palm Oils etc. can be directly refined without use of expensive chemicals and without generation of effluents. The process is very cost effective where the oil is first pretreated with Phosphoric Acid in a specially designed mixer. After adequate retention the oil is fed to the bleaching section when colour bodies are removed.

The Bleached Oil in then fed into the deacidification-deodorizing section. The free fatty acids are stripped completely and recovered as valuable by products. The deacidifed oil is then deodorized in the deodorizing trays. The process results in huge cost savings. This process is highly recommended for hard oils like Palm Oil.
