FIELD: processes of mass transfer including distillation, absorption-desorption and liquid-liquid extraction. SUBSTANCE: column has liquid distributor in upper part, row of perforated liquid-foaming plates spaced apart and directly supporting packed layers of packing which fill path of gas stream in body. Common perforation of cross-section area, cross-section area of each perforation per each plate are so chosen that penetrability of densified layers is such that plates and densified layers of packing facilitate considerable to contact of gas and liquid. EFFECT: enhanced efficiency of mass transfer in proposed column with packing. 8 cl, 6 dwg
