    Distillation by filtration: In early alchemy and chemistry, otherwise known as natural philosophy, a form of "distillation" by capillary filtration was known as a form of distillation at the time.

  3. Steam distillation - Wikipedia

    en.wikipedia.org/wiki/Steam_distillation

    Steam distillation apparatus. Steam distillation is used in many of the recipes given in the Kitāb al-Taraffuq fī al-ʿiṭr ('Book of Gentleness on Perfume'), also known as the Kitāb Kīmiyāʾ al-ʿiṭr wa-l-taṣʿīdāt ('Book of the Chemistry of Perfume and Distillations'), attributed to the early Arabic philosopher al-Kindi (c. 801 –873).

  4. 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 .

  5. 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.

  6. Condenser (laboratory) - Wikipedia

    en.wikipedia.org/wiki/Condenser_(laboratory)

    In chemistry, a condenser is laboratory apparatus used to condense vapors – that is, turn them into liquids – by cooling them down. [1] Condensers are routinely used in laboratory operations such as distillation, reflux, and extraction. In distillation, a mixture is heated until the more volatile components boil off, the vapors are ...

  7. Retort - Wikipedia

    en.wikipedia.org/wiki/Retort

    In a chemistry laboratory, a retort is a device used for distillation or dry distillation of substances. It consists of a spherical vessel with a long downward-pointing neck. The liquid to be distilled is placed in the vessel and heated.

  8. Fractionation - Wikipedia

    en.wikipedia.org/wiki/Fractionation

    Here the distillation head and fractionating column are combined in one piece. Differential centrifugation . Fractionation is a separation process in which a certain quantity of a mixture (of gasses, solids, liquids, enzymes , or isotopes , or a suspension ) is divided during a phase transition , into a number of smaller quantities ( fractions ...

  9. Theoretical plate - Wikipedia

    en.wikipedia.org/wiki/Theoretical_plate

    The concept of theoretical plates in designing distillation processes has been discussed in many reference texts. [2] [3] Any physical device that provides good contact between the vapor and liquid phases present in industrial-scale distillation columns or laboratory-scale glassware distillation columns constitutes a "plate" or "tray". Since an ...
