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.

A distillation plant comprising:
- a column;
- packing arranged along a vertical axis within the column;
- at least two vaporizers arranged along the vertical axis within the column;
- a sump;
- a head of the column;
- and
- at least two liquefiers arranged along the vertical axis within the column;
- wherein the packings and the vaporizers are executed such that a slight pressure drop arises during operation of the plant between the sump and the head of the column;
- wherein a first of the at least two vaporizers is arranged one of either in or directly above the sump;
- wherein an intermediate vaporizer of the at least two vaporizers is arranged above the first vaporizer and a lower packing section;
- wherein a first liquefier of the at least two liquefiers is arranged in the head of the column;
- and
- wherein an intermediate liquefier of the at least two liquefiers is arranged below the first liquefier and an upper packing section.
