HEAT AND MASS EXCHANGE APPARATUS Russian patent published in 2006 - IPC B01D3/30 B01D53/18 

FIELD: chemical engineering.

SUBSTANCE: apparatus comprises rotating shaft and cylindrical housing with the flanges and bottoms. The top section of the housing receives branch pipes for supplying and discharging gas. The bottom section of the housing receives the branch pipes for supplying and discharging liquid. The housing is provided with the assembly of separating ring baffles interposed between the cylindrical inserts and interconnected by means of longitudinal studs, which defines the transverse central sections and two side sections from the side of bottoms. The end sections from the side of flanges with bottoms receive heat exchanging devices made of a ring (spiral) tubular heat exchangers mounted coaxially with respect to the contact stacks. The sections with built-in heat exchanger for supplying heat and branch pipe for discharging liquid defines boiler. The section provided with the heat exchanger for withdrawing heat and branch pipes for discharging condensate of light fractions (phlegm and steam-gas phase defines dephlegmator (and condenser). The central sections with longitudinal radially oriented plates, branch pipes for supplying accelerated fluid and discharging liquid and condensate of fractions define rectifying apparatus. The heat and mass exchange apparatus is inclined to the boiler at an angle 0.1-5°.

EFFECT: reduced sizes and mass.
