Problems solved by technology

However, structured packing elements with a high specific surface area are characterized by a high flow resistance of the light phase, which means that the corresponding structured packing elements have a higher pressure drop per packing height for a given flow rate of the light phase, and thus a higher pressure drop than The reason why fillers with lower specific surface area have lower capacity

Embodiment Construction

[0092] figure 1 A schematic side view of a mass transfer column 10, and more specifically a distillation column 10, according to one embodiment of the present invention is shown (the transparent interior of the figure is for illustrative purposes only). Again, for illustrative purposes, the grid structure of the layers is not shown in figure 1 , but only shown in Figure 6. Distillation column 10 includes a plurality of structured packing elements 12 arranged in two beds 14, 14'. Distributors 16, 16' are arranged above each of the two beds 14, 14' to distribute the liquid evenly across the cross-section of the beds, while leaving sufficient space for the vapor to rise through it. A grid-like holding device 18 and a collector 20 are arranged below each bed 14 , 14 ′, wherein the grid-like holding device 18 holds the bed 14 in place and the collector 20 collects the trickle down from the bed 14 . liquid while leaving enough open space in the collector for the vapor to r...

Abstract

The invention relates to a structured packing element for a column for mass transfer and / or heat exchange between a heavy fluid phase and a light fluid phase, in which the structured packing element comprises at least two layers of a grid comprising openings surrounded by separating elements and separated from each other, wherein at least two of the at least two layers are arranged parallel in a longitudinal direction and in contact with each other such that an open space is provided therebetween extending from one end of the at least two layers to an opposite end such that at least one of the heavy fluid phase and the light fluid phase can flow therethrough, wherein at least 50% of the average width of the separating elements between adjacent openings is at least 15 times the thickness of the layer material and is between 70% and 125% of the average hydraulic diameter of the adjacent openings, and wherein a maximum distance between at least two of the at least two layers measured in a plane perpendicular to the longitudinal direction is at least four times an average width of the separation element.

Description

technical field [0001] The present invention relates to a structured packing element for a column for mass and / or heat exchange between a heavy fluid phase and a light fluid phase. Background technique [0002] Structured packing elements are used in mass transfer columns such as, for example, fractionation columns, distillation columns, absorption columns, extraction columns or flue gas scrubbers. The structured packing elements are used to improve mass and / or heat transfer between at least two fluid phases having different densities, wherein the structured packing elements are typically operated in countercurrent flow. Whereas in distillation and absorption applications, the light phase is a gas or vapor, and the heavy phase is a condensate or liquid, during extraction, both phases are liquids with different densities. The structured filler element includes a plurality of distinct layers, each of which provides a surface area for a heavier phase that trickles down and spr...
