  2. 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; ...

  3. Distilled water - Wikipedia

    en.wikipedia.org/wiki/Distilled_water

    Bottled distilled water can usually be found in supermarkets or pharmacies, and home water distillers are available as well. Water purification, such as distillation, is especially important in regions where water resources or tap water is not suitable for ingesting without boiling or chemical treatment.

  4. List of purification methods in chemistry - Wikipedia

    en.wikipedia.org/wiki/List_of_purification...

    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.

  5. Air separation - Wikipedia

    en.wikipedia.org/wiki/Air_separation

    Distillation column in a cryogenic air separation plant. The cryogenic separation process [4] [5] [6] requires a very tight integration of heat exchangers and separation columns to obtain a good efficiency and all the energy for refrigeration is provided by the compression of the air at the inlet of the unit.

  6. Fractional distillation - Wikipedia

    en.wikipedia.org/wiki/Fractional_distillation

    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 .

  7. Category:Distillation - Wikipedia

    en.wikipedia.org/wiki/Category:Distillation

    Distillation is a method of separation of substances based on differences in their volatilities. This process is essentially governed by Raoult's law and Dalton's law

  8. Solar still - Wikipedia

    en.wikipedia.org/wiki/Solar_still

    Solar-powered desalination systems can be installed in remote locations where there is little or no infrastructure or energy grid. Solar is still affordable, eco-friendly, and considered an effective method amongst other conventional distillation techniques. Solar still is very effective, especially for supplying fresh water for islanders.

  9. Molecular distillation - Wikipedia

    en.wikipedia.org/wiki/Molecular_distillation

    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 ...
