Abstract
The orderly packing for a column for mass transfer between a trickling film (14) and a gas is made of alternately arranged layers (10, 20) of undulating foil material. Some of the layers (10) steer the trickling film towards one vertical edge (13) of the layers while the other layers (20) steer the trickling film away from that edge. Pairs of invention the layers are coupled by redirector elements (3) which form a liquid-conducting bridging-over to transfer edge-seeking liquid (15) on the one layer (10) at least partially to the associated neighboring layer (20).
