The first process is known as distillation. In this process, crude oil is heated and fed into a distillation column. A schematic of the distillation column is shown in (Figure text { } 2.2). As the temperature of the crude oil in the distillation column rises, the crude oil separates itself into different components, called "fractions."

Due to the presence of two long lipophilic fatty acid chains and a hydrophilic phosphate group on the same molecule, the PLs behave like emulsifiers and responsible for oil loss in refining process. PLs have to be eliminated in the early refining stage because they decompose under heating and caused oil darkening at high deodorisation …
However for comparative purposes, we can assume that at the beginning the possible installation can process 1 tonne of refining waste containing 0.05% of each precious metal (Pt, Pd, Rh, and Au).
Refining output is larger than input. The total volume of products that refineries produce (output) is greater than the volume of crude oil that refineries process (input) because most of the products they make have a lower density than the crude oil they process. This increase in volume is called processing gain. The average processing …

Acid Refining. This process is applicable to both water degummed oil and oils that have not yet been water degummed. Like the acid degumming process, the process uses a degumming acid to decompose the NHP, but instead of diluting this acid with water making it weaker, the acid refining process neutralizes partially the PA by the addition of alkali.
