  2. 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 .

  3. Fractionation - Wikipedia

    en.wikipedia.org/wiki/Fractionation

    Fractionation makes it possible to isolate more than two components in a mixture in a single run. This property sets it apart from other separation techniques. Fractionation is widely employed in many branches of science and technology. Mixtures of liquids and gasses are separated by fractional distillation by difference

  4. Fraction (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Fraction_(chemistry)

    In such a process, a mixture is separated into fractions, which have compositions that vary according to a gradient. A fraction can be defined as a group of chemicals that have similar boiling points. A common fractionating process is fractional distillation, in which separation is achieved by condensing a vapor over a range of temperatures. [1]

  5. 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.

  6. Air separation - Wikipedia

    en.wikipedia.org/wiki/Air_separation

    An air separation plant separates atmospheric air into its primary components, typically nitrogen and oxygen, and sometimes also argon and other rare inert gases. The most common method for air separation is fractional distillation. Cryogenic air separation units (ASUs) are built to provide nitrogen or oxygen and often co-produce argon.

  7. Fractionating column - Wikipedia

    en.wikipedia.org/wiki/Fractionating_column

    A fractionating column or fractional column is equipment used in the distillation of liquid mixtures to separate the mixture into its component parts, or fractions, based on their differences in volatility. Fractionating columns are used in small-scale laboratory distillations as well as large-scale industrial distillations.

  8. Separation process - Wikipedia

    en.wikipedia.org/wiki/Separation_process

    A separation process is a method that converts a mixture or a solution of chemical substances into two or more distinct product mixtures, [1] a scientific process of separating two or more substances in order to obtain purity. At least one product mixture from the separation is enriched in one or more of the source mixture's constituents.

  9. Azeotrope - Wikipedia

    en.wikipedia.org/wiki/Azeotrope

    Distillation is one of the primary tools that chemists and chemical engineers use to separate mixtures into their constituents. Because distillation cannot separate the constituents of an azeotrope, the separation of azeotropic mixtures (also called azeotrope breaking) is a topic of considerable interest. [13]
