PLANT FOR ADSORPTION IN CLOSED CYCLE OF EXCESS CO FROM MIXTURE BASED ON NOBLE GASES USING TECHNOLOGY OF THERMAL REGENERATION OF SORBENT Russian patent published in 2024 - IPC B01D53/26 

FIELD: chemical or physical processes.

SUBSTANCE: plant for adsorption in a closed cycle of excess CO₂ from a mixture based on noble gases using technology of thermal regeneration of sorbent relates to means of air purification and maintenance of standard levels of carbon dioxide (CO₂) in air for breathing in confined spaces. Adsorption unit comprises a sealed housing, a system for blowing air through a regenerated CO₂ adsorbent, an air cleaning system, liquid CO₂ adsorbent distribution system, CO₂ adsorption unit, air flow braking system, CO₂ adsorbent regeneration unit, heating system, cooling system, aeration system, CO₂ removal unit, purified air removal unit. CO₂ removal unit and the purified air removal unit each contain at least one shutter. Aeration system contains at least three partitions, and the air flow braking system contains fillers and at least one partition. Partitions have holes. Plant also includes an air intake unit, which includes a pre-cleaning filter and an air flow inducer including an air flow activator.

EFFECT: invention provides higher efficiency of air purification, reduced carbon dioxide in air medium, due to increased adsorption of CO₂, automatic maintenance of specified level of CO₂ concentration.
