Abstract
The packing elements are made of a strip of foil-like material which has at least one trickle surface for a descending flow of liquid. This surface is provided with alternating smooth portions and finely-fluted portions which extend over a height of at least five millimeters. In addition, at least the smooth portions are perforated. The packing element may be formed of a plurality of flat corrugated plates, or may be spirally wound from a continuous strip to form an ordered packing or may be in the form of cylinders to form a random packing.

A packing element for an exchange column comprising
- a plurality of vertically disposed corrugated plates of foil-like material each having a longitudinal axis disposed in contacting parallel relation and parallel to said axis, each plate having corrugations disposed at an angle to the corrugations of an adjacent plate, each said plate forming a surface for receiving a descending flow of liquid thereon, said surface being sub-divided perpendicularly of said axis to have alternating smooth portions extending transverse to said corrugations and finely-fluted portions extending transverse to said corrugations, said finely-fluted portions being laterally disposed to laterally distribute the liquid under capillary action.
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 vertically disposed corrugated plates of foil-like material disposed parallel to said axis and in contacting relation, each said plate having corrugations disposed at an angle to the corrugations of an adjacent plate, each said plate forming a surface for receiving a descending flow of liquid thereon, said surface being sub-divided perpendicularly of said axis to have alternating smooth portions extending transverse to said corrugations and finely-fluted portions extending transverse to said corrugations, said finely fluted portions being laterally disposed to laterally distribute the liquid under capillary action.
