SPLIT-FLOW CONTACTOR Russian patent published in 2012 - IPC B01D15/04 B01J19/24 

FIELD: machine building.

SUBSTANCE: split-flow contactor includes housing having the first head and the second head located on it, two or more separate fixed beds located in the housing cross section, one or more flow passages for bypass of each fixed bed, which have no obstacles, and one or more partition walls located between fixed beds. Each fixed bed includes one or more catalysts, one or more ion exchange resins, one or more absorbents, one or more adsorbents or any of their combinations. According to the tank modernisation method, two or more supporting sieves are arranged inside the tank; at that, each sieve is located separately; one or more obstacle-free flow passages through each of the above supporting sieves is formed, and one or more partition walls are arranged between adjacent supporting sieves. Besides, one or more partition walls are mainly perpendicular to flow passages. According to the method for bringing into contact of one or more fluid media and one or more solid products, the supplied material is introduced to contactor, the first portion of the supplied material is passed through the first fixed bed so that the first effluent is obtained; the second portion of the supplied material is passed through one or more flow passages bypassing the first fixed bed. After that, the second portion is passed through the second fixed bed so that the second effluent is obtained; the first effluent is passed through one or more flow passages bypassing the second fixed bed and the first and the second effluents are combined. According to the other version, split-flow contactor includes the housing having the first head and the second head located on it, two or more separate fixed beds located in the housing cross section and mixing volume located between beds. Each fixed bed includes one or more catalysts, one or more ion exchange resins, one or more absorbents, one or more adsorbents or any of their combinations, and each bed includes one or more circular flow passages located in it. Effluent from the first bed can come in contact and be mixed with effluent from the second bed in it. The supplied material can enter the contactor through any two elements chosen from the group consisting of the first head, the second head and the housing.

EFFECT: reduction of pressure drop on the bed, and reduction of contactor cross section surface area.
