The invention relates to a packing assembly for a material exchange column, comprising at least one structured packing plate and a container in which the at least one structured packing plate is arranged. The at least one structured packing plate has packing packets. Each packing packet has interconnected packing sheets. The packing sheets are corrugated and have corrugation peaks and corrugation valleys. Adjacent packing sheets contact each other at the corrugation peaks. Additional corrugated packing sheets are added between the packing packets such that the at least one packing plate is pretensioned against the container in a radial direction thereof. Both the corrugated packing sheets of the packing packets as well as the additional corrugated packing sheet added between the packing packets are arranged solely on a common preferred plane or parallel thereto.

Packing assembly, material exchange column, and method

The invention relates to a shell and tube heat exchanger () having a helical tube bundle () within a shell (), that defines a shell space () surrounding the tube bundle (). The tubes are helically coiled about a core pipe () in such a manner that there is formed at least one first section () and at least one second section (), separate from the first section, that surrounds the first section (). The two sections () have in each case at least one associated inlet (E, E') such that the two sections () are able to be charged separately with the first medium.

Heat exchanger with sections

The invention relates to a heat exchanger () for indirect heat exchange comprising a tube bundle (), formed from a plurality of tubes helically coiled around a core tube (), for receiving a first medium, a shell (). which encloses the tube bundle () and defines a shell space () surrounding the tube bundle (), for receiving a second medium, and a liquid distributor () for distributing in the shell space () a stream (S), conveyed in the shell space (), of the second medium in the form of a liquid (F). According to the invention a control device () for controlling distribution in the shell space () of an additional, further stream (S') of liquid (F), and/or for controlling distribution of stream (S) of liquid (F) in the shell space ().
