Explain how crude oil is separated into fractionsCrude oil is separated by fractional distillation. Crude oil is heated and the oil evaporates. It then goes into the tower. As the vapours rise up the tower the temperature rises. Different sized fractions condense at different heights because they have different boiling points. Larger molecules condense high up in the tower. Smaller molecules condense low down in the tower. Then the fractions are collected.Crude oil is separated by fractional distillation.
