Process Description

For refining the oil, there are three basic processes in the refinery. First process is neutralizing the oil in the neutralizer to remove the Free Fatty Acids (FFA) by adding caustic soda. Oil is heated upto about 60°C by thermic fluid coils and oil is stirred by stirrer. Then soap stock formed due to chemical reaction is allowed to settle at the bottom of the neutralizer from where it is taken out into soap pan.

Additional Process for palm oil refinery:

Specially for palm oil refinery, fractionation process is required in which palm olene and palm sterene are separated by scientifically cooling the refined palm oil by chilling plant and then filtering the oil. For this purpose crystalizing vessel is used in which chilling pipe coils cool the oil for fractionation. Palm sterene crystals are formed due to chilling which are separated in the filter press and pure liquid of palm olene is obtained and palm sterene cake is retained in the filter press.

Specifications of Edible Oil Refinery:

All the main vessels i.e. two neutralizers, one bleacher and one deodourizer are properly arranged on the first floor of the steel structure. So all these vessels are hanging on the steel strucutre. Just below the two neutralizers, two soap pans are resting on the ground floor in which soap stock is collected. There is a steam pipe arrangement in the soap pans also.
