Column

The individual parts of the column can be variously equipped (jacketed, working and manipulation of the nozzle, footing, legs, etc.). The number of parts of the column (the composition) follows the customer's requirements. Columns can be pressurized or unpressurized, with grids of different materials (enamel, halar, titanium, hasteloy) or equipped with additional accessories.

Most often, vapours are brought into the bottom part of the column, and liquids to the top part. Within the column the material changes from liquid to gas and consequently the gas phase is enriched or depleted of components that are soluble in the liquid phase.
