Abstract

The packing element is made up of a plurality of corrugated plates which are provided with a plurality of apertures as well as with a fine fluting on the walls of the corrugations. The flutings are disposed on both sides of the plates. The flutings are in the form of grooves which extend at an angle to the axis of the column which is of opposite sign to the angle of the corrugations relative to the axis of the column.

Claims

1. A packing element for an exchange column comprising

a plurality of corrugated plates of foil-like material disposed in parallel relation, each said plate having corrugations disposed at an angle and in criss-crossing relation to the corrugations of an adjacent plate, each said plate having a plurality of apertures distributed therein, and each said corrugation of each plate having a laterally extending fine fluting therein whereby said apertures and said fine fluting effect a uniform distribution of a downwardly flowing liquid under capillary action.

2. A packing element as set forth in claim 1 wherein said fluting is in the form of grooves.

3. A packing element as set forth in claim 2 wherein said grooves of each plate are disposed at an angle of opposite sign from said angle of said corrugations of each respective plate.

4. A packing element as set forth in claim 3 wherein said grooves are disposed at an angle of 15°

to 90°

relative to the packing and said corrugations are disposed at an angle of 15°

to 60°

relative to the packing.

5. A packing element as set forth in claim 1 wherein said plates are made of metal.

6. A packing element as set forth in claim 1 wherein said plates are made of plastics.

7. A packing element as set forth in claim 1 wherein said fluting has a wave length of from 0.3 to 3.0 millimeters.

8. In combination with an exchange column having a longitudinal axis,

at least one packing element in said column, said packing element including a plurality of corrugated plates of foil-like material disposed parallel to said axis and in contacting relation, each said plate having corrugations disposed at a first angle relative to said axis and in criss-crossing relation to the corrugations of an adjacent plate, each said plate having a plurality of apertures distributed therein, and each said corrugation of each plate having a laterally extending fine fluting therein whereby said apertures and said fine fluting effect a uniform distribution of a downwardly flowing liquid under capillary action.

9. The combination as set forth in claim 8 wherein said fluting is in the form of grooves.

10. The combination as set forth in claim 9 wherein said grooves are disposed at an angle of 15°

to 90°

relative to said axis and said first angle is from 15°

to 60°

.

11. The combination as set forth in claim 8 wherein said fluting has a wave length of from 0.3 to 3.0 millimeters.
