Fractional distilation

Crude oil is a mixter of diffrent hydrocarbons.

Fractional distilation allows these diffrent hydrocarbons to be seperated.

Diffrent hydrocarbons have diffrent boilling points.

Long-chained hydrocarbons have high boiling points.

Short-chained hydrocarbons have low boiling points.

Crude oil is heated in fractionation column,the fractionating
