Fractional distillation is a method used in separating volatile (having a tendency to vaporize) liquids. Fractional distillation has been used traditionally in the separation of mixtures and purification of solvents, chemicals and other naturally occurring material. Fractional distillation has found widespread use in oil refineries, where it is used in separating constituents of oil into its basic components, which can then be sold as petroleum, crude oil, spirit and other industrial products.
