Abstract
A gas/liquid contact apparatus that includes a plurality of packing sheets arranged in parallel, vertical, upright, face-to-face relationship. The packing sheets have a series of inclined corrugations formed therein. Each of the corrugations is formed so as to define an alternating series of longitudinally extending, oppositely inclined surfaces that intersect and pass through a center plane of the packing sheet so as to define hills and valleys. The packing sheets are secured together at contact points, wherein the hills of one of the packing sheets contacts the valleys of an immediately adjacent packing sheet. The relative location and the distance between the adjacent hills and valleys in adjacent corrugations varies so as to cause the contact points to be dispersed over a relatively wide area of the surfaces of the packing sheets.
