CONTROL SYSTEM OF MULTICOMPONENT OXYGEN-CONTAINING GAS MEDIUM IN SEALED CONTAINER AND METHOD OF SYSTEM ACTIVATION Russian patent published in 2020 - IPC B01J19/24 F17C7/04 G01N30/14 C01B13/02 

FIELD: chemistry.

SUBSTANCE: invention relates to control technology of composition of multicomponent gaseous medium and systems of safe storage of chemically active or aggressive materials and can be used for monitoring of explosion- and fire-hazardous systems. Control system of multicomponent oxygen-containing gas medium in closed volume includes containers with adsorbents, perforated membrane, which make zone of selective separation of gaseous components, and a closed type reactor for carrying out a catalytic reaction for obtaining water from oxygen and hydrogen, filled with powdered chemical oxygen source (COS) and made with double walls, in the interstyle space of which there is a granular complex catalyst. One of the containers contains an adsorbent for absorption of water vapour, and the second one, into which a multicomponent oxygen-containing gas medium of the specified composition is supplied, which is connected through a perforated membrane with a container with a chemically active substance (CAB), contains adsorbent for absorption of organic gaseous compounds. All containers and reactor are combined into a single closed system and in each container measuring instruments are installed for monitoring of gas medium state.

EFFECT: system ensures possibility of maintaining optimum composition of multicomponent gaseous medium, improved safety of functioning and efficiency of gas medium regulation due to timely and controlled supply of oxygen into tank with chemically active substance.
