RECTIFICATION COLUMN Russian patent published in 2012 - IPC B01D3/30 

FIELD: process engineering.

SUBSTANCE: invention relates to mass-transfer apparatuses for rectification of fluid mixes. Rectification column comprises still, partial condenser, housing with process branch pipes consisting of rings with horizontal baffles arranged there between. Said baffles have holes provided with heat-transfer devices made up of coils. Horizontal baffles at column bottom section are equipped with contact branch pipes including tangential swirlers, deflector, fluid discharge branch pipe, outer cylinder and hydro lock barrel. Heat-transfer devices are arranged in steam space of rings above horizontal baffles and provided with, at least, one plate flanged on one side and arranged horizontally with clearance between coil turns. Restrictors are arranged in coils to maintain preset consumption of coolant. Extra swirlers with tangential channels are arranged at top end of cylindrical hydro lock barrels. Bottom faces of outer cylinder and fluid discharge branch pipe are located below channels of steam from tangential swirlers. Ratio of said swirler diameter to said branch pipe diameter is made equal to D_s/D_b=1.5-3.0.

EFFECT: higher efficiency, reduced overall dimensions and metal consumption.
