METHOD OF ADSORPTION OF CO FROM ATMOSPHERIC AIR USING TECHNOLOGY OF THERMAL REGENERATION OF SORBENT Russian patent published in 2024 - IPC B01D53/04 

FIELD: gas cleaning.

SUBSTANCE: method of adsorption of CO₂ from atmospheric air using the technology of thermal regeneration of the sorbent is characterized by that an air flow is supplied inside the housing. Air flow is passed through filters with filler. Simultaneously, filters with fillers are washed with liquid CO₂ adsorbent from top to bottom. Liquid CO₂ adsorbent, falling on the surface of the fillers, flows into the lower part of the housing. Liquid CO₂ adsorbent is delivered from the lower part of the housing to the upper part for repeated washing of the fillers. Liquid CO₂ adsorbent is regenerated for a certain period of time by heating and holding the liquid CO₂ adsorbent in a heated state. Carbon dioxide produced after regeneration of liquid adsorbent CO₂ is removed. Purified air is passed through post-treatment filters. Fillers are made in the form of glass, ceramic, plastic or polyethylene balls. Air flow is passed through a pre-filter. Air flow is supplied inside the housing under pressure. Air flow is passed through filters with fillers in vertical and horizontal directions. Liquid CO₂ adsorbent is regenerated in the lower part of the housing. Filters with fillers are continuously washed with liquid CO₂ adsorbent.

EFFECT: invention provides higher efficiency of air cleaning, as well as reduced level of carbon dioxide (CO₂) in air medium and reduced level of costs due to increased efficiency of use of liquid adsorbent CO₂ and its thermal regeneration in a sealed housing.
