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.

Abstract: A splash bar for use in crossflow cooling tower fill assemblies. The splash bar has (1) a substantially horizontal upper surface, (2) two downwardly extending side surfaces terminating at their lower edges in substantially horizontal inwardly directed flanges, and (3) at least one downwardly extending rib intermediate the side surfaces and terminating at its lower edge in a substantially horizontal flange. All of the flanges are in the same substantially horizontal plane, and all are spaced from one another to facilitate extrusion of the splash bar and to prevent accumulation of water and debris in the splash bar. The upper surface may be perforate or imperforate.

Abstract: A gas/liquid contact apparatus which 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 are formed so as to define an alternating series of longitudinally extending oppositely inclined surfaces which intersect and pass through a center plane of the packing sheet so as to define hills and valleys. The inclined surfaces have an amplitude relative to the center plane of the packing sheet which is opposite that of the adjacent inclined surfaces of an adjacent corrugation. The packing sheets are arranged adjacent each other such that the corrugations of adjacent packing sheets are oppositely oriented. The adjacent packing sheets are secured together where the hills of one of the packing sheets contacts the valleys of an immediately adjacent packing sheet.

Abstract: A fill section arrangement for crossflow cooling towers which utilizes a mixture of high density fill strip regions and low density fill strip regions. The regions of the fill section which include the high density fill strips are those regions which have the highest enthalpy driving forces.
