Abstract
A packing element for mass transfer column or towers and/or heat transfer columns or towers through which a gas and/or a liquid flows, is provided herein. The packing element possesses a plurality of exchange surfaces. The exchange surfaces of the packing element are formed by the surfaces of half-wave-shaped strips or wave-shaped strips. The packing element also possesses at least one first group of strips containing at least one half-wave-shaped strip or wave-shaped strip having a first periodic length, and at least one second group of strips adjoining thereto and containing at least one half-wave-shaped or wave-shaped strip having a second periodic length. Preferably, at least one outer side of the packing element is formed as a boundary element joining at least some of the strips of a group of strips.
