Crude oil is a complex mixture of hydrocarbons with varying chain lengths and boiling points. Fractional distillation involves heating the crude oil and separating the vapours into different fractions at various levels of a fractionating column based on their condensation temperatures. Lighter fractions with lower boiling points rise higher in the column, while heavier fractions with higher boiling points condense lower down.
