When starting with very good quality crude palm oil (low FFA and high DOBI), chemical refining is able to purify the oil so effectively that the bleaching step can be skipped or performed with very small amounts of non-activated bleaching earths or with silica.
How phosphoric acid is used to bleach crude oil?
Classically, the hot crude oil is first mixed with 0.05¨C0.1% (w/w) concentrated phosphoric acid; after a short retention time, acid activated bleaching earth is contacted under vacuum at 80¨C120°C. After suitable contact time, the bleaching earth is removed by filtration.
How is crude oil mixed with phosphoric acid?
The hot crude oil is thoroughly mixed with phosphoric or citric acids; after a retention time of 5¨C20 minutes, 2¨C5% of water is added before separation on a centrifuge. One property of phosphatides is that they form hydrates in contact with water and these hydrates are less soluble in oil.
How is palm oil packaged and distributed?
Packaging and Distribution: Once the palm oil has been refined and fractionated (if applicable), it is packaged and distributed to customers worldwide. This stage involves careful quality control and adherence to strict regulations to ensure that the palm oil meets the required standards for use in various applications.
