SYSTEM FOR EXTRACTING CO AND METHOD OF EXTRACTING CO Russian patent published in 2020 - IPC B01D35/18 

FIELD: manufacturing technology.

SUBSTANCE: system for extraction CO₂ comprises absorber CO₂ for CO₂ removal from exhaust gases using absorbent CO₂, absorbent regenerator, intended for regeneration of absorbent CO₂, line L₁₁ supply of enriched solution, used for supply of enriched solution from absorber to point from input of enriched solution into regenerator, heat exchanger of enriched/depleted solutions, in which heat exchange is performed between enriched solution and lean solution, first line L_13-1 separation of enriched solution intended for separation of part of enriched solution in first separation unit A-1 located on line L₁₁ feeding rich solution between enriched/depleted solution heat exchanger and regenerator, and feeding the separated enriched solution to the first rich enrichment point B-1, which is on the side wall closer to the regenerator lower side than the rich solution feed point, first heat exchanger of enriched solution, serving for preliminary heating of separated part of enriched solution, and a first flow control device for controlling flow of rich solution separated in first separation unit A-1, such that enriched solution is heated in first heat exchanger of enriched solution to a predetermined temperature.

EFFECT: disclosed are a system for extracting CO₂ and method of extracting CO₂.
