A mass-transfer column consisting of one or more contact zones. The contact zones are exclusively provided with packings placed in prearranged locations. In the contact zones, optimal operating conditions for the packings are created over the entire height of the contact zones in order to achieve a minimal pressure loss at a concomitant high separating efficiency. This is done by implementing a suitable gradated adaptability of the packing to the vapor and liquid loads varying over the height of the contact zones.

Mass-transfer column for liquid-vapor contact processes, provided with packed tower internals and consisting of one or a plurality of a contact zone(s), wherein every contact zone is subdivided into immediately contiguous packed tower internals, characterized by the entire packed tower internals of one contact zone (1) containing a plurality, but a minimum of, three immediately contiguous horizontal packings (3; 4; 5) of varying geometry but identical basic structural configuration, said varying geometry having influence upon the vapor and liquid loading capacity of such a gradation that the free-flow sectional area is adapted to the load, thereby operating in the optimal load range of each of said packings.
