Palm acid oil (PAO) is a by-product obtained from the refining of palm oil. Palm Acid Oil specifications contain mainly of Free Fatty Acid (FFA) up to 50% and neutral oil, with 2-3% moisture and other impurities. It is similar to palm fatty acid distillate but its FFA is generally lower.
Palm acid oil is a by-product of palm oil refining by chemical methods. It is also known as caustic refining because caustic soda is used in this method to neutralize the free fatty acids present in crude palm oil. The production of palm acid oil contains three steps: pretreatment, neutralization, and acidulation.
Crude palm oil undergoes degumming with concentrated phosphoric acid followed by adsorptive cleansing with bleaching earth (bentonite calcium). Crude palm oil is mixed with phosphoric acid of 80 – 85% concentration at a flow rate of 0.05 – 0.2% that of the feed oil and the mixture is heated to 90 – 110°C. The heated mixture is allowed for a residence time of 15 – 30 minutes before passing to the bleacher unit where bleaching earth is added as slurry. The bleaching process is carried out at a temperature range of 95 – 110°C under a vacuum of 20 – 25 mm of Hg and for a time interval of 30 – 45 minutes. The amount of earth required depends upon the quality of crude palm oil and it varies from 0.8 to 2% of feed oil. The purpose of mixing phosphoric acid is to precipitate non-hydratable phosphatide. The function of mixing of earth bleach are
Degummed oil is treated with caustic soda solution of about 4N concentration with 20% excess, this results in the formation of sodium soap, which is removed by centrifugal separation. The lighter phase consists mainly of neutralized oil containing about 500-1000 mg/kg of soap and moisture, while the heavy phase is mainly soap, gums, insoluble impurities, excess alkali, phosphatides, and a small quantity of oil loss by emulsification. The soap stock is separated out using a centrifugal separator.
The soap stock is treated with dilute sulphuric acid of pH 2 – 3.5 at a temperature of 110 – 130°C for a time interval of 30 minutes, which gives palm acid oil. The palm acid oil is separated out from aqueous solution by a centrifugal separator. After separation from aqueous solution, palm acid oil is washed with hot water to remove any impurities still present in it. Palm acid oil mainly contains free fatty acids, partial glyceride, and neutral oil.
In the manufacturing of animal feed, palm acid oil (PAO) is used as a raw material
Palm acid oil (PAO) is used as the base material for biodiesel manufacturing.
Palm acid oil is used to manufacture palm-based different fatty acids for industrial uses. Mainly palmitic acid, oleic acid, stearic acid, and linoleic acid are manufactured from palm acid oil. Since it is cheaper compare to crude palm oil, so it finds applications in the manufacturing of low-cost fatty acid for industrial applications.
Palm acid oil also can be used to manufacture various palm-based fatty acids such as palmitic acid, oleic acid, stearic acid, and linoleic acid.
Palm acid oil (PAO) is used as a raw material in the production process of laundry soaps
Palm acid oil (PAO) is obtained as a byproduct of refined palm oil. It is used for making laundry soaps for animal feed formulations. The properties and composition of PAO may differ according to variations in the palm oil feedstock and the alkaline refining process.
