ABSTRACT:
The invention relates to a packing (2) for a material and heat exchange column (1), in which a gas phase and a liquid phase are brought into contact with one another, said packing comprising a multiplicity of identical packing elements (4) which are substantially in the form of a circular hollow cylinder whose annularly extending wall (6) is outwardly concave and inwardly convex and forms two outer edges (11) extending therearound, said hollow cylinder having a high ratio of outside diameter (D) to height (H). In order to reduce the pressure drop and to increase capacity and effectiveness, provision is made for the packing (2) to consist of a multiplicity of superimposed layers (3) of packing elements (4) which lie flat, are distributed randomly in each layer (3), and internally have a free passage cross-section, and in which the ratio of outside diameter (D) to height (H) is from about 6:1 to about 10:1.
