| fractional distillation of crude oil |
In the fractional distillation of crude oil,the crude oil is heated above 400c and pumped
into the fractionating column where the components condense at their respective boiling points.
Conversion process
Conversion processes are the technique that are used to improve the quality of petrol product after initial distillation.
The techniques used are:
* Hydro treating
* Catalytic reforming
* Catalytic cracking
Hydro treating: It is a refining process for removing sulphur and other undesirable elements from petroleum products.
Catalytic reforming : catalytic reforming is a chemical process used to covert linear hydrocarbons to high brand hydrocarbon.
Catalytic cracking :This is the breakdown of higher molecular weight petroleum fraction into lighter ones with the use of catalyst.
It can yield petroleum of higher octane number. Example of octane
number is 2,2,4 trimethylpentane
