The fractional distillation process facilitates separation by heating a mixture to a temperature at which one or more of its fractions vaporize. In doing so, it takes advantage of the different vapor pressure properties of the various chemical compounds in a component substance. This technique allows the production of highly purified products ...

Fractional distillation is the process by which oil refineries separate crude oil into different, more useful hydrocarbon products based on their relative molecular weights in a distillation tower. This is the first step in the processing of crude oil, and it is considered to be the main separation process as it performs the initial rough separation of the different fuels.
