Abstract:
A method for installing a structured packing in an exchange column, comprising the steps of:providing an exchange column; providing a structured packing having a surface area density in the range of about 350 m2/m3 to about 800 m2/m3, comprising a plurality of corrugated plates disposed in vertically parallel relation, each plate having at least one aperture and a plurality of regularly spaced and substantially parallel corrugations disposed in crisscrossing relation to the corrugations of an adjacent plate, wherein the apertures have an equivalent diameter less than about 4 millimeters but greater than about 2 millimeters, and wherein the corrugations have a corrugation angle (&agr;) relative to horizontal in the range of about 35Â° to about 65Â° and each corrugation, when approximated to be a substantially triangular cross-section, has an included angle (&bgr;) defined by two sides of the corrugation in the range of about 80Â° to about 110Â°; and installing the structured packing in the exchange column.
