Abstract
A novel pourable packing element is provided herein for use, in particular, in mass transfer and/or heat transfer towers through which a gas or a liquid flows. The exchange areas of such packing element are formed by the surfaces of half-wave-shaped or wave-shaped strips. The packing element possesses at least a first group of strips having a first periodic length and at least one adjoining second group of strips having at least one strip with a second periodic length. The first periodic length of a selected first strip in the first group of strips, (such selected first strip adjoining the second group of strips), and the second periodic length of a selected second strip in the second group (such selected second strip adjoining the first group of strips), is matched to each other in such a way that two adjoining strips of the first group of strips and the second group of strips are in contact with one another at at least one point, so that liquid can pass from one strip to the other strip.
