Embodiment Construction

[0049] figure 1 The device 1 according to the invention is shown, which comprises several packing layers of a structured packing unit 9 , which form the packing body. A structured filling unit 7 means a device for exchanging substances between two fluid phases. The structured packing unit 7 is used in the substance exchange device 2 . In particular, the mass exchange device can be designed as a column 5 .

[0050] The structured packing unit 7 is formed from a plurality of packing layers which are in a regularly repeating geometric relationship with respect to one another. As an example for such a geometric relationship, the spacing of adjacent filling layers can be chosen. According to the geometric relationship, the distances between adjacent filling layers periodically have the same value, so that a structure is produced from the sum of the filling layers, which is characterized by the same or at least periodically identical spacing. The periodicity can be found throug...

Abstract

The invention relates to a device for purifying fluids, comprising a mass transfer apparatus that contains a more volatile fluid and a less volatile fluid. The mass transfer apparatus contains a structured packing having a first packing unit (10) and a second packing unit (100). The first packing unit (10) and the second packing unit (100) have a wave-like profile, wherein open channels (12, 14, 16, 112, 114, 116) are formed by the wave-like profile. The channels (12, 14, 16) of the first packing unit (10) intersect with the channels (112, 114, 116) of the second packing unit, wherein the channels (12, 14, 16, 112, 114, 116) can be traversed by the less volatile fluid so that the channel can be wetted by the less volatile fluid, whereby a film of the less volatile fluid forms on the surface of the channel so that either the more volatile fluid or the less volatile fluid can be purified by means of a mass transfer between the more volatile fluid and the less volatile fluid. The first packing unit (10) is in physical contact with the second packing unit (100) via spacer elements (24, 34, 44, 134, 144).

Description

technical field [0001] The invention relates to a method for purifying fluids, which is preferably carried out in a plant for purifying fluids, such as an absorption or desorption tower. The device comprises a structured packing unit whose pressure loss is reduced. The packing unit is especially suitable for systems with watery properties such as CO from flue gas 2 Absorption application scheme for absorbent systems. Background technique [0002] The principle of structured packing cells has been used in absorption for decades (cf. K. Sattler "Thermische Trennverfahren", VCH Verlag, Weinheim 1995), since the energy used for this and the structure of the absorption tower can be saved high. [0003] In a commercially customary embodiment, the structured packing unit is designed as folded, successively arranged metal sheets, the structure of which has oblique and always recurring intersecting grooves. These grooves positively influence the flow of the gaseous and liquid pha...
