Using alkali like (NaOH) to neutralize FFA in oil, during this process it will produce soapstock , then separating it from the oil. NAOH solution not only neutralize free fatty acid, but also can act with other substances like protein, mucus, phospholipid, pigment.
C.Decolorization Section:
Because there is pigment in crude oil, the oil color is dark. In order to improve oil color, we need to using the active clay to absorb the pigment away , then using vibrating filter to separate the waste clay. If you want to get light color oil, you need to add more active clay. Customer can accord to his requirement to control the oil color.
