Problems solved by technology

[0007] A disadvantage of the fillers proposed according to document US 6,378,332 B1 is their insufficient mechanical stability
Furthermore, the volume filled by the filler material is not filled optimally with the geometrical exchange surface due to the partial not too high fold, ie this structural design is accompanied by a loss of the material exchange surface

Embodiment Construction

[0050] figure 1 A device 1 according to the invention is shown comprising several layers of structured packing 7 which form the packing body. Structured packing 7 is understood to be a medium for the exchange of substances between two fluid phases. Structured packing 7 is used in the mass exchange device 2 . The substance exchange device can be embodied in particular as a column 5 which can be used for absorption or desorption.

[0051] The structured packing 7 consists of layers which are in a regularly repeating geometric relationship to one another. The spacing of adjacent layers may be chosen as an example of a relationship for this geometry. Due to this geometric relationship, the distances of adjacent layers from one another can periodically assume the same value, so that the sum of the layers results in a structure which is characterized by the same or at least periodically the same distances. This periodicity occurs throughout the structured packing, whereby the pa...

Abstract

An absorber or desorber contains a layer (10) for a structured packing having a wave-like profile, wherein a plurality of open channels (12, 14, 16) is formed due to the wave-like profile. According to the invention, said open channels have a first wave trough (22), a first wave peak (32) and a second wave peak (42). The first wave peak (32) and the second wave peak (42) delimit the first wave trough (22), the first and second wave peaks having a first apex (33) and a second apex (43). A depression (34) extending in the direction of the first apex (33) is formed on the first apex (33) of the first wave peak (32). The first wave trough (22) has a trough bottom (23), wherein the normal distance (27) from at least one point of the depression (34) to the trough bottom (23) of the wave trough (22) is smaller than the normal distance (28) from the first apex (33) to the trough bottom (23) of the wave trough (22).

Description

technical field [0001] The invention relates to a structured packing as well as to a mass exchange device, such as an absorption column or a desorption column, comprising a structured packing of this type. Background technique [0002] In a commercially common embodiment, the structured packing is designed as a folded, continuous arrangement of metal sheets, the structure of which has oblique and repeatedly intersecting channels. These channels positively influence the flow of gaseous and liquid phases within the packing and facilitate mass transport between the phases. That is to say, in the channels of the packing, the gaseous and liquid phases are brought into contact and thus facilitate the transport of substances between the phases. [0003] In order to increase the separating capacity of the structured packing, the surface of the structured packing is usually increased, which is usually achieved by a greater number of layers and / or narrower channel geometries. Howeve...
