If the content of FFA in crude oil is high, we will lost much oil and get much soapstock. But if the content of FFA in crude palm oil is low, we will get more oil and less soapstock.

Decolorization section: Decolorization is carried out by the obsorption function of white clay, this step usually need 25mins, temperature requirements around 105-110 Celsius.

Deodorization section: This step have high temperature requirement , around 260 Celsius, based on very high temperature, steam can remove oxidation number, aldehydes, and ketones in crude oil. In addition, some of acid and bad smell also can be taken off in this step..
