Abstract
Tower packing elements adapted for dumped packing and employed to effect vapor-liquid contact in vapor-liquid contact columns for the purposes of bringing about mass and heat transfer between the liquid and vapor phases. Each packing element is of the saddle variety and is arcuately formed about orthogonal notional axes. The body of the saddle comprises expanded metal; that is, metal that has been perforated, lanced, and/or expanded by stretching along oppositely oriented axes. Also disclosed are methods of forming a segmented, semi-toroidal tower packing element from metal which has been expanded, as well as from metal which has been slitted, and which is expanded at the same time as it is formed into a saddle shape. In this manner, the advantages of metal in tower dump packing can be utilized in a saddle configuration maximizing vapor-liquid contact and efficiency of the mass and heat transfer.
