Definitions
- the invention relates to an ordered packing for heat and / or mass transfer columns with at least one packing layer of several packing layers.
- the packing for distillation columns are prepared according to the prior art from sub-elements of the same geometry, such as zigzag-shaped bent sheets, expanded metals or wire mesh.
- the purpose of this uniform geometric design is that over the entire column cross-section as uniform as possible flows of gas and liquid occur. Deviations from this, especially marginalities of the liquid or stratification of the liquid, must be avoided, as this negatively affects the separation performance.
- To remedy such negative non-uniform liquid distributions it is necessary to use liquid collector and liquid distributor at intervals of a few meters. In addition to the equipment costs of these installations also their installation height of about 1, 5 to 2.5 m negative, since this increases the height of the columns.
- the object of the invention is to achieve a uniform liquid distribution over the column cross-section in a package of the type mentioned in a simple structure.
- the packing layer has packing layers which, compared to the other packing layers of the same packing layer, have a greater density and thus a larger surface area.
- FIG. 1 shows a first embodiment of a packing unit / packing layer in the cutout
- FIG. 2 shows a second embodiment of a packing unit / packing layer in the neck.
- packing beds In a column several packing beds are arranged horizontally one above the other at a distance.
- the beds have one or more packing layers 3, which consist of Packing layers 4a, 4b are composed, which may be arranged vertically or obliquely.
- Figures 1 and 2 show sections of packing layers 3 according to the invention, in which the packing layers have at least two different sized specific surfaces.
- two narrower denser packing layers 4b are installed adjacent to the higher specific surface. Between these layers 4b with the larger specific surface are 1 to about 10, preferably 3 to 6, adjacent layers 4a having a smaller specific surface area.
- the specific surface area of the smaller specific surface layers 4a corresponds to the geometries customary in the art with a specific surface area of about 150 to 750 m 2 / m 3 .
- the larger specific surface layers 4b have about a factor of 2 to 10 larger specific surface area.
- the reason for this very large specific surface area is the incorporation-deviating function used by the usual distillation techniques.
- the interspaces of the packing layers 4b with the larger specific surface are preferably only or predominantly with liquid flows through. In these fluid-filled gaps occurs a good homogenization of a portion of the liquid flow and a uniform distribution.
- Such packing layers therefore have a distributive effect. They make separate arrangements of liquid collectors and liquid distributors wholly or at least partially dispensable. In order to achieve a mass transfer between the gas phase and the liquid even in the case of the narrow liquid-filled packing layers 4b, these packing layers are preferably produced from materials which have perforations, for example expanded metal or wire mesh.
