FIELD: technological processes.
SUBSTANCE: invention relates to a column for mass transfer between a liquid phase and a gaseous phase directed countercurrent therewith. Column with lateral wall (10) passing along longitudinal axis (L), which surrounds internal space of column (1, 2, 3, 4), at least one mass-exchange plate (100), which is extended along cross-section (Q) of column (1, 2, 3, 4) passing through longitudinal axis (L), and at least one liquid distributor (200, 300), which is intended for loading of at least one mass-exchange plate (100) by liquid phase (F). Mass-exchange plate (100) has elongated in parallel and at some distance from each other drain elements (101), in particular, in the form of angle profiles, which in each case extend along cross section (Q) of the column. In each case, drain elements (101) have the first and second drainage surfaces (102a, 103a) extended along the cross-section (Q) of the column, and both drain surfaces (102a, 103a) pass to each other along the longitudinal axis (L) in direction to liquid distributor (200, 300) and mate with each other to form rib (104) passing along cross section (Q) of column.
EFFECT: liquid distributor (200, 300) is intended to supply liquid phase (F) to ribs (104) of drain elements (101) so that liquid phase (F) supplied to this drain element (101) flows on both sides of this rib (104) through drain surfaces (102a, 103a) from said draining element (101).
