FIELD: separation.
SUBSTANCE: invention relates to the flue gases cleaning method and system, in particular to the mercury and / or mercury-containing components sequestration from the flue gases. Method comprises the bromine-containing powdered activated carbon adsorbent introduction into the flue gas stream with the adsorbent dispersion formation in the flue gases stream, wherein the flue gases stream flows directly into the wet scrubber composition, the holding time provision for the adsorbent in the flue gases stream dispersion, before the adsorbent input to the wet scrubber composition for possibility of contact between the adsorbent and mercury and / or mercury-containing flue gases stream components and to enable the mercury and / or mercury-containing components sequestration from the flue gases by adsorbent, ensuring the dispersed adsorbent passage in the flue gases stream directly to the wet scrubber composition to minimize the mercury release from the flue gases stream, wherein the flue gases are formed in the furnace, and a bromine compound introduction into the furnace. System includes the flue gases source in the furnace, pipeline for the flue gases transfer, gas scrubber cavity connected to the pipeline and comprising the wet scrubber mixed composition, which directly catches flue gases and the adsorbent injector for the adsorbent introduction into the dispersion formation pipeline upstream of the gas scrubber cavity.
EFFECT: invention enables more efficient mercury from the flue gases sequestration.
