Abstract
The present invention provides a structured packing comprising a plurality of corrugated sheets and a plurality of flat, planar members alternating with and located between the sheets to inhibit turbulence in vapor ascending through the structured packing. The plurality of planar members are positioned so that at least lowermost transverse edges of the planar members and the corrugated sheets are situated at least proximal to one another as viewed when said structured packing is in use. Each of the planar members and the corrugated sheets has perforations sized to inhibit liquid and vapor flows but to allow pressure equalization. The planar members can be strip-like and positions at or near the top and bottom transverse edges of the corrugated sheets or can have the same length and width of the corrugated sheets. The size and number of perforations can be optimized for air separation applications.
