INSTALLATION FOR ABSORBING SOLUTION REGENERATION, INSTALLATION FOR CO EXTRACTION, AND METHOD FOR ABSORBING SOLUTION REGENERATION Russian patent published in 2023 - IPC B01D53/14 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to an installation for absorbing solution regeneration, to an installation for CO₂ extraction, and to a method for regeneration of an absorbing solution. The installation for absorbing solution regeneration contains a regenerator for absorbing solution regeneration by removal of CO₂ from the absorbing solution that has absorbed CO₂, the main pipeline for an enriched solution, providing supply of the absorbing solution that has absorbed CO₂ to the first place of the regenerator. It also contains the first heating device for heating of the absorbing solution passing through the main pipeline for the enriched solution, wherein the first heating device is located on the main pipeline for the enriched solution. It contains an outlet pipeline for the enriched solution, providing supply of part of the absorbing solution passing through the main pipeline for the enriched solution to the regenerator, wherein the outlet pipeline for the enriched solution branches off from the main pipeline for the enriched solution. The outlet pipeline for the enriched solution contains the first outlet section branching off from the first branch point located on the main pipeline for the enriched solution and upstream relatively to the first heating device, the second outlet section branching off from the second branch point located on the main pipeline for the enriched solution and downstream relatively to the first heating device; and a downstream section, which is a section located downstream relatively to a point of connection of the first outlet section with the second outlet section. The downstream section is made with the possibility of supply of part of the absorbing solution to the second place of the regenerator, wherein the second place is located below the first place. The installation for absorbing solution regeneration additionally contains regulating means for regulating the ratio between the first flow rate of the absorbing solution passing through the first outlet section and the second flow rate of the absorbing solution passing through the second outlet section. An installation for CO₂ extraction, containing an absorber and the claimed installation for absorbing solution regeneration, and a method for regeneration of an absorbing solution are also claimed.

EFFECT: group of inventions provides simplification of regulation of a temperature of fluid obtained at an installation for absorbing solution regeneration.
