State the use of gasoline.
The petrol used to fuel our cars.
State the use of diesel oil.
Used in diesel engines; particularily for large vehicles.
Crude Oil
Oil is a mixture of hundreds of hydrocarbons. This mixture must be separated into its useful components by fractional distillation.
Fractional Distillation
Very hot crude oil is pumped into the fractionating column where the hydrocarbons separate out by their boiling points, rising through the column until they get cold enough to condense. The compounds that condense at a particular temperature are called a fraction.
