In petroleum processing involves two main processes, namely:
1. The process of separation
2. The process of conversion
Refining process (refines) first of all is to change the component
oil into fractions which sells a few types of distillation.
Some chemical treatments and heating is carried out to improve the quality
of crude oil derived products. For example in 1912 the demand
gasoline exceeds supply and to meet the demand then used
process of "warming" and "pressure" is high to change the fraction that is not
expected. Large molecules into smaller ones in the gasoline boiling point range,
This process is called cracking.
