2. In this step, free fatty acids are neutralized by using sodium hydroxide and convert them into soap. Additional impurities are also removed by adsorption on soap.

3. During bleaching process, unwanted pigments are adsorbed physically and oil will become much clearer.

4. Deodorization machine is used to remove unacceptable odors by steam distillation during palm kernel oil refinery plant, the odoriferous compound are stripped off with the help of live injected steam into heated oil under high vacuum pressure.
