MASS-EXCHANGE COLUMN Russian patent published in 1999 - IPC

FIELD: absorption and rectification processes. SUBSTANCE: invention is related to rotor apparatuses to conduct absorption and rectification processes, specifically, rectification under conditions of vacuum of thermally unstable products. Demerit of other known structures lies in inadequate efficiency of mass exchange and low liquid-phase productivity. Package of truncated cones which vertexes face upwards has horizontal discs anchored on bases of cones in upper part. Vertical perforated cylinder having holes in the form of horizontal slits spaced apart at some distance along height is anchored outside discs. Salient feature of invention consists in fitting of package of cones with horizontal discs and vertical perforated cylinder which form circular distribution pockets. EFFECT: increased number of layers of atomization of liquid and enlarged surface of contact of phases. 2 cl, 3 dwg
