For many cases, the boiling points of the components in the mixture will be sufficiently close that Raoult's law must be taken into consideration. Therefore, fractional distillation must be used in order to separate the components by repeated vaporization-condensation cycles within a packed distillation column.
This separation, by successive distillations, is also referred to as rectification. The fractional distillation equipment is widely used in purifying solvents, chemical, natural products, petroleum, bio-diesel, crude oil and other materials.
