Contact plates having perforations for the passage of a gas or a vapor are arranged along the height of said vertical cylindrical casing. Each of said contact plates is provided with a central overflow device or two peripheral overflow devices, respectively, in an alternating fashion and consists of two identical segments which are secured along their chords to a central box. The axis of said central box coincides with the axis of said vertical cylindrical casing. The length of said central box substantially corresponds to the diameter of said vertical cylindrical casing. Said central box has parallel rows of apertures located above the level of said contact plates. Said central overflow devices are arranged inside said central box.
