ABSTRACT:
A distillation plant contains a column with packings as well as a vaporizer. The elements of the column are arranged along a vertical axis and assembled as a constructional unit. They are executed in such a manner that a slight pressure drop sets in during the operation of the plant between a sump and a head. At least two vaporizers are provided, namely a first vaporizer, which is arranged in or directly above the sump, and an intermediate vaporizer which is arranged above the first vaporizer and a lower packing section; and/or at least two liquefiers are provided, namely a first liquefier, which is arranged in the head of the column, and an intermediate liquefier, which is arranged below the first liquefier and an upper packing section.
