  2. Separation process - Wikipedia

    en.wikipedia.org/wiki/Separation_process

    Demister (vapor), removes liquid droplets from gas streams; Distillation, used for mixtures of liquids with different boiling points; Drying, removes liquid from a solid by vaporization or evaporation; Electrophoresis, separates organic molecules based on their different interaction with a gel under an electric potential (i.e., different travel)

  3. Decantation - Wikipedia

    en.wikipedia.org/wiki/Decantation

    Decanting a liquid from a solid. Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension. [1] The layer closer to the top of the container—the less dense of the two liquids, or the liquid from which the precipitate or sediment has settled out—is poured off, leaving denser liquid or the solid behind.

  4. List of purification methods in chemistry - Wikipedia

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

    Refining is used primarily in the petroleum industry, whereby crude oil is heated and separated into stages according to the condensation points of the various elements. 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 ...

  5. Chromatography - Wikipedia

    en.wikipedia.org/wiki/Chromatography

    Chromatography, pronounced / ˌ k r oʊ m ə ˈ t ɒ ɡ r ə f i /, is derived from Greek χρῶμα chrōma, which means "color", and γράφειν gráphein, which means "to write".". The combination of these two terms was directly inherited from the invention of the technique first used to separate biological pigme

  6. Filtration - Wikipedia

    en.wikipedia.org/wiki/Filtration

    Filters may be used for the purpose of removing unwanted liquid from a solid residue, cleaning unwanted solids from a liquid, or simply to separate the solid from the liquid. There are many different methods of filtration; all aim to attain the separation of substances. Separation is achieved by some form of interaction between the substance or ...

  7. Industrial separation processes - Wikipedia

    en.wikipedia.org/wiki/Industrial_separation...

    Energy-separating agents are used for creating a second phase (immiscible of different composition than the first phase), they are the most common techniques used in industry. For example, leads the addition of heat (the separating agent) to a liquid (first phase) to the formation of vapor (second phase). Mass-separating agents are other chemicals.

  8. Decanter centrifuge - Wikipedia

    en.wikipedia.org/wiki/Decanter_Centrifuge

    With a 3 phase decanter centrifuge, it is possible to separate 3 phases from each other in one process step only. For example, two liquids which cannot be mixed because of different densities (e.g. oil and water) are separated from a solids phase. The heavy liquid (water) collects in the middle between the oil and the solids layer.

  9. Solid-phase extraction - Wikipedia

    en.wikipedia.org/wiki/Solid-phase_extraction

    A vacuum port with gauge is used to control the vacuum applied to the chamber. Solid-phase extraction (SPE) [1] is a solid-liquid extractive technique, by which compounds that are dissolved or suspended in a liquid mixture are separated, isolated or purified, from other compounds in this mixture, according to their physical and chemical ...
