B.Deacidification section:Using alkali like (NaOH) to neutralize FFA in oil, during this process it will produce soapstock , then separating it from the oil.
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. the oil color can be control led by clay amount.
