METAL PACKING AND METHOD OF MANUFACTURE

摘要

METAL PACKING AND METHOD OF MANUFACTURE Metal vapor/liquid contact plates are disposed in faceto-face contact with respective corrugations inclined to the horizontal across a notional plane. In one embodiment, a perforated lamella or partition plate is disposed across the notional plane. The metal packing which may also be of slit or louvered construction 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 expanded 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 lamella plate formation may also afford select flow and turbulence characteristics through capillary action between offset lamella land areas of the corrugated sheets.
