FIELD: process engineering.
SUBSTANCE: proposed system comprises absorber and regenerator. Absorber comprises CO2 absorption section and water rinsing section. Said absorption section allows flue to be exposed to adsorbent based on main amino compound to absorb carbon dioxide in flue gas. Water rinsing section allows decarbonated flue gas with reduced amount of carbon dioxide to get in contact with circulating rinsing water to reduce amount of amino compounds trapped by decarbonated flue gas. Regenerator release absorbed carbon dioxide from main amino compound-based absorbent. Proposed system comprises also device to concentrate rinsing water of aforesaid section. Concentrated water from said section is returned into said rinsing section.
EFFECT: additional decrease in concentration of main amino compound.
