    Below is a schematic flow diagram of a typical crude oil distillation unit. The incoming crude oil is preheated by exchanging heat with some of the hot, distilled fractions and other streams. It is then desalted to remove inorganic salts (primarily sodium chloride). Following the desalter, the crude oil is further heated by exchanging heat with ...

  4. Atmospheric distillation of crude oil - Wikipedia

    The hot crude oil is then passed into a distillation column that allows the separation of the crude oil into different fractions depending on the difference in volatility. The pressure at the top is maintained at 1.2–1.5 atm [ 2 ] so that the distillation can be carried out at close to atmospheric pressure, and therefore it is known as the ...

    [1] [2] [41] Below is a schematic flow diagram of a typical crude oil distillation unit. The incoming crude oil is preheated by exchanging heat with some of the hot, distilled fractions and other streams. It is then desalted to remove inorganic salts (primarily sodium chloride). Following the desalter, the crude oil is further heated by ...

  6. Fractional distillation - Wikipedia

    en.wikipedia.org/wiki/Fractional_distillation

    For example, fractional distillation is used in oil refineries to separate crude oil into useful substances (or fractions) having different hydrocarbons of different boiling points. The crude oil fractions with higher boiling points: have more carbon atoms; have higher molecular weights; are less branched-chain alkanes; are darker in color; are ...

  7. Continuous distillation - Wikipedia

    en.wikipedia.org/wiki/Continuous_distillation

    Image 1: Typical industrial distillation towers Image 2: A crude oil vacuum distillation column as used in oil refineries. Continuous distillation, a form of distillation, is an ongoing separation in which a mixture is continuously (without interruption) fed into the process and separated fractions are removed continuously as output streams.

  8. 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.

    Here the distillation head and fractionating column are combined in one piece. The apparatus shown in the diagram represents a batch distillation as opposed to a continuous distillation . The liquid feed mixture to be distilled is placed into the round-bottomed flask along with a few anti-bumping granules , and the fractionating column is ...
