Abstract
Abstract Disclosed is a tower packing for vapor-liquid contact which includes a plurality of sheets (34) of corrugated material, the sheets being arranged generally vertically and parallel to one another with the corrugations of adjacent sheets criss-crossing one another. The sheets (34) are provided with a plurality of holes (36) for effecting both liquid and vapor distribution in said packing, and the holes (36) are arranged on the sheets (34) with the horizontal spacing between adjacent holes being no greater than about five times the horizontal extent of a hole, and in no event greater than about 5 millimeters. The horizontal extent of the holes (36) is no greater than about 2 millimeters. In one form the packing is constructed so that the angle said corrugations strike to the vertical axis of the packing and the fold-to-fold dimension of the corrugations are so selected with respect to the horizontal and vertical extent of a hole and the horizontal and vertical spacing between adjacent holes that a plurality of said holes (36) fall on a given corrugation fold (35) of a sheet (34).
