FIELD: reaction-and-mass-transfer processes, particular, designs of columns for conduction of catalytic reaction-and-mass-transfer processes. SUBSTANCE: the offered apparatus has body with alternating sections provided with distributing and spraying members, supporting grates and bubble-cap trays. One sections of column has shell with bubble-cap tray located in the upper part, supporting grate in section lower part connected with shell and the second shell of small diameter located in section lower part connected by means of horizontal partition with body and liquid sprayer including sieve cone-shaped partition or bubble-cap tray and cylindrical member with perforated tray in the lower part of distributor. The other sections of column have shell whose upper part has conical distributing grate or circular horizontal tray with caps connected with body, plugged from bottom with circular horizontal partition. Located coaxially to the shell is the second shell with small diameter, plugged from above by horizontal partition and having holes in the lower part, and discharge pipe connected with liquid sprayer. Located above plugged horizontal partition is supporting grate, and the third and fourth sections of the column have supporting grate connected with the column body. EFFECT: higher efficiency. 6 dwg
