    Distillation, widely used in petroleum refining and in purification of ethanol separates volatile liquids on the basis of their relative volatilities. There are several type of distillation: simple distillation, steam distillation etc. Water purification combines a number of methods to produce potable or drinking water.

  3. Distillation - Wikipedia

    en.wikipedia.org/wiki/Distillation

    Distillation, also classical distillation, is the process of separating the component substances of a liquid mixture of two or more chemically discrete substances; the separation process is realized by way of the selective boiling of the mixture and the condensation of the vapors in a still.

    Fractional distillation is the separation of a mixture into its component parts, or fractions. Chemical compounds are separated by heating them to a temperature at which one or more fractions of the mixture will vaporize .

    Molecular distillation is a type of short-path vacuum distillation, characterized by an extremely low vacuum pressure, 0.01 torr or below, which is performed using a molecular still. [1] It is a process of separation, purification and concentration of natural products, complex and thermally sensitive molecules for example vitamins and ...

    Distillation removes all minerals from water. This results in demineralised water, which has not been proven to be healthier than drinking water. The World Health Organization investigated the health effects of demineralised water in 1982, and its experiments in humans found that demineralised water increased diuresis and the elimination of ...
