摘要： The performance of structured packing comprising a plurality of corrugated plates (20) disposed in vertically parallel relation, each plate (20) having at least one aperture (28) and a plurality of regularly spaced and substantially parallel corrugations disposed in crisscrossing relation to the corrugations of an adjacent plate (20) is optimized by having a surface area density in the range of 350 to 800 m 2 /m 3 , preferably 500 to 675 m 2 /m 3 ; aperture equivalent diameters of less than 4 millimetres but greater than 2 millimetres; a corrugation angle (α) relative to horizontal in the range of 35° to 65°, preferably 40° to 60°; and an included angle (β) defined by two sides of the corrugation in the range of 80° to 110°, preferably 90° to 100°. The structured packing is used in exchange columns for exchanging heat and/or mass between a first phase and a second phase in processes such as cryogenic air separation.
