Chemistry - Refining crude oil

Refining crude oil

Oil purification process

Oil separation process

Crude oil is our primary source of fuels and petrochemicals. Refining
crude oil to separate out and modify useful components of the complex
mixture of 2000 different substances involves three distinct stages:

* - where non-hydrocarbon compounds are removed

* - where the crude oil is separated into fractions containing
hydrocarbons of similar molecular size and boiling temperatures

* - where hydrocarbon molecules are restructured to produce molecules
with particular properties

Aviation fuel

The separation of crude oil into _fractions_ is the source of fuels such
as petrol, aviation fuel and heating oil as well as the _feedstock_ for the
production of a wide range of other derived petrochemicals. One of the most
important of these derived petrochemicals is_ ethene_.

So important are petrochemicals at the start of the third millennium, that
petroleum may soon become too valuable to use as a source of transport fuel
and will need to be conserved for future petrochemical development.
