  2. Fractionating column - Wikipedia

    en.wikipedia.org/wiki/Fractionating_column

    Figure 5: Section of fractionating tower of Figure 4 showing detail of a pair of trays with bubble caps Figure 6: Entire view of a Distillation Column. In industrial uses, sometimes a packing material is used in the column instead of trays, especially when low pressure drops across the column are required, as when operating under vacuum.

  3. Fractional distillation - Wikipedia

    en.wikipedia.org/wiki/Fractional_distillation

    Diagram of a typical industrial distillation tower. Large-scale industrial towers use reflux to achieve a more complete separation of products. [5] Reflux refers to the portion of the condensed overhead liquid product from a distillation or fractionation tower that is returned to the upper part of the tower as shown in the schematic diagram of ...

  4. Distillation - Wikipedia

    en.wikipedia.org/wiki/Distillation

    Section of an industrial distillation tower showing detail of trays with bubble caps. Design and operation of a distillation tower depends on the feed and desired products. Given a simple, binary component feed, analytical methods such as the McCabe–Thiele method [41] [50] or the Fenske equation [41] can be used.

  5. 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.

  6. Packed bed - Wikipedia

    en.wikipedia.org/wiki/Packed_bed

    A packed bed used to perform separation processes, such as absorption, stripping, and distillation is known as a packed column. [1] Columns used in certain types of chromatography consisting of a tube filled with packing material can also be called packed columns and their structure has similarities to packed beds.

  7. Crude oil stabilisation - Wikipedia

    en.wikipedia.org/wiki/Crude_oil_stabilisation

    The crude oil is fed to a stabilizer which is typically a tray or packed tower column that achieves a partial fractionation or distillation of the oil. [4] The heavier components, pentane (C 5 H 12), hexane (C 6 H 14), and higher hydrocarbons (C 7 +), flow as liquid down through the column where the temperature is increasingly higher.

  8. Stripping (chemistry) - Wikipedia

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

    Stripping is mainly conducted in trayed towers (plate columns) and packed columns, and less often in spray towers, bubble columns, and centrifugal contactors. [2] Trayed towers consist of a vertical column with liquid flowing in the top and out the bottom. The vapor phase enters in the bottom of the column and exits out of the top.

  9. Oil refinery - Wikipedia

    en.wikipedia.org/wiki/Oil_refinery

    The cooling and condensing of the distillation tower overhead is provided partially by exchanging heat with the incoming crude oil and partially by either an air-cooled or water-cooled condenser. Additional heat is removed from the distillation column by a pumparound system as shown in the diagram below.
