Metal vapor-liquid contact plates disposed in face-to-face contact with respective corrugations inclined to the horizontal across an open notional plane. The metal packing is disposed within a vapor-liquid contact column for the purpose of bringing about mass and heat transfer between liquid and vapor passing in opposite directions therethrough. The body portion of each metal plate comprises metal that has been slitted to provide both surfaces thereof with a very large number of apertures with little wasted material. The metal lands defining the apertures are, moreover, twisted and angulated. The apertures in the plates also trap liquid and expose it to the vapor stream on both sides of the metal affording self-spreading of the liquid and turbulent vapor flow therethrough. In this manner, the assembly affords optimal pressure drop characteristics, surface to vapor passage area ratio, and vapor-liquid distribution characteristics. The laminate plate formation may also afford select flow and turbulence characteristics through capillary action between offset laminate land areas of the corrugated sheets.

An improved method of improving vapor liquid contact within a process tower of the type comprising the steps of providing a generally vertical tower having means for ingressing the flow of vapor at the lower region thereof and means for ingressing a stream of liquid at the upper region thereof and a series of layers of grid sections comprising generally vertically oriented corrugated sheets of unexpanded material with the corrugations of adjacent sheets being inclined one to the other between said liquid and vapor ingressing means for receiving the descending flow of liquid and the ascending flow of vapor concomitantly therethrough, said improvement comprising the steps of providing said corrugated sheets with a plurality of parallel, elongate, spaced apart slits formed through solid surfaces of each sheet with the total area of all of said slits being smaller than the total area of said solid surfaces, providing said slitted sheets with a plurality of relatively larger apertures spaced apart by said solid surfaces for effecting the flow of vapor and liquid therealong and within the corrugations of said adjacent sheets for enhancing the vapor liquid interaction, and the further step of orienting the longitudinal axes of said elongate slits in said sheets to extend generally transversely to said vapor liquid flow and said corrugations for imparting turbulence thereto along with a transverse spreading effect to the liquid flowing down and through said sheets. A tower packing comprising a plurality of sheets of unexpanded material, a plurality of corrugations formed on each sheet, said sheets being disposed in face-to-face contact with the corrugations of each sheet extending at an angle to the corrugations of its adjacent sheets to define flow paths for a descending liquid and an ascending vapor, a plurality of relatively large orifices formed through and spaced apart by solid surfaces of each sheet for permitting passage of said liquid and vapor therethrough to distribute the liquid over said sheets and equalize the pressure of said vapor, and a plurality of relatively small elongated slits formed through the solid surfaces of each of said sheets, the slits in each sheet being spaced longitudinally from each other in parallel rows with the longitudinal axes of said slits extending transversely across said corrugations, the total area of all of said slits being smaller than the total area of said solid surfaces, a portion of each sheet adjacent each slit being displaced from the plane of said sheet, to enhance vapor-liquid contact along said sheets.
