FIELD: mining industry.
SUBSTANCE: invention is intended for the extraction of carbon dioxide. The carbon dioxide extraction system contains a number of absorption columns designed for a number of fuel-burning devices, to absorb carbon dioxide present in the exhaust gases coming out of each of the series of these fuel-burning devices by bringing the exhaust gas into contact with the absorbent liquid, and at least one regeneration column communicating with each of the series of absorption columns designed to extract carbon dioxide from an absorbent liquid enriched with CO2, which is an absorbent liquid, coming out of each of the row of absorption columns. The number of regeneration columns is less than the number of absorption columns.
EFFECT: reduced installation costs of the carbon dioxide extraction system.
