FIELD: process engineering.
SUBSTANCE: invention relates to method of carbon dioxide extraction and installation to this end. Proposed installation comprises absorber to bring exhaust gases containing carbon dioxide in contact with its absorber in countercurrent conditions to reduce carbon dioxide content, and regenerator to recover rich solution of adsorbed carbon dioxide. Note here that weak solution with carbon dioxide content reduced in regenerator is reused in absorber. Absorber comprises, at least, one carbon dioxide absorption section to extract sais gas from exhaust gases. Absorbent with absorbed carbon dioxide is discharged from the absorber section rich solution side, cooled and fed into location proximate to weak solution side for it to be reused for carbon dioxide extraction again.
EFFECT: higher efficiency, reduced power consumption.
