Embodiment Construction

[0056] figure 1 A device 1 according to the invention is shown comprising certain packing layers of a structured packing 7 forming a packing body. A device for transferring mass between two fluid phases is to be understood as a structured packing 7 . Structured packing 7 is used in mass transfer device 2 . The mass transfer device can in particular be made as a column 5 .

[0057] The structured packing 7 is made of a plurality of packing layers in a regularly repeating geometric relationship with respect to each other. As an example for such a geometry, the distance between adjacent packing layers can be chosen. Depending on the geometry, the distances of adjacent packing layers from each other can periodically assume the same value, so that a structure is produced from the sum of the packing layers, which is characterized by the same or at least periodically the same distances. This periodicity exists in general structured packings, thereby giving the packings a regular ...

Abstract

The present invention relates to a packing layer (10) for regulating the packing. The packing layer is provided with ripples, wherein a plurality of open channels (12, 14, 16) are formed by the ripples, wherein the channels comprises 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) define the first wave trough (22), wherein the first wave peak and the second wave peak have a first peak (33) and a second peak (43). The first peak (33) of the first wave peak (32) is provided with an insulation element (34) which extends in the direction of the first peak (33). The first wave trough (22) is provided with a trough base (23), wherein the insulation component (34) is provided with an edge (35). Compared with the first peak (33) of the first peak (32), a larger vertical distance is provided between the edge (35) and the trough base (23) of the wave trough (22).

Description

technical field [0001] The present invention relates to a structured packing and a column, in particular an absorption column, comprising such a structured packing. The invention relates in particular to a structured packing which reduces pressure loss and which is particularly suitable for absorption applications using aqueous absorbents, such as the absorption of CO from flue gas 2 . Background technique [0002] The principle of structured packings has been used for decades in absorption (cf. K. Sattler "Thermische Trennverfahren" [Thermal Separation Processes (thermal separation processes)], VCH Verlag, Weinheim 1995), since energy to be input can thus be saved and the structural height of the absorption tower. [0003] The structured packing is produced in one commercial embodiment as corrugated metal sheets arranged one behind the other, the structure of which has oblique channels which continuously intersect each other. These channels have a positive effect on gas ...
