It's called Distiling...
Crude oil is a micture of diffrent lengths of Hydrocarbons and they each boil at diffrent tempretures so the Crude Oil is put into a big tube (sort of) and then heated up and each set of hydrocarbons will boil at a different tempreture and will reach the top of the tub were it is then collected...
Very basic answer...
