METHOD OF REMOVING OXYGEN FROM WATER Russian patent published in 2018 - IPC C02F1/20 C02F1/42 B01J47/02 B01J49/00 

Abstract RU 2655141 C1

FIELD: heat-and-power engineering.

SUBSTANCE: invention can be used in heat-and-power engineering to protect heat exchange equipment, boilers, pipelines and other metal elements in electrical power generating plant, firerooms, industrial plants in the production of steam, obtaining hot water for water supply, obtaining desalted and softened water. To carry out the process, the raw water is filtered through low- and high-basic mesoporous anion exchange materials synthesized by modification of copolymers of styrene and divinyl benzene in sulfite form. Regeneration of waste anion exchange materials is carried out by successive processing with solutions of natron or alkali with transfer to the main form, and a solution of sodium bisulphite with concentration of 1–10 % is passed through ion exchanger.

EFFECT: with this processing of resin charge, effective persorption of the sulfite anions occurs, which doubles the oxygen ion capacitance, which is removed from the water; the method also provides for increasing the efficiency of the use of ion exchanger and minimizing the volume of liquid waste.
