METHOD AND INSTALLATION FOR JOINT FLUE GAS CLEANING WITH SEVERAL POLLUTANTS Russian patent published in 2023 - IPC B01D53/75 B01D53/50 B01D53/56 B01D53/60 B01D53/78 

FIELD: environmental protection.

SUBSTANCE: group of inventions is related method and installation for treatment of pollutants, in particular to a method and installation for joint cleaning of flue gas with several pollutants. The method and apparatus for synergistic purification of flue gas with multiple pollutants includes, after denitrification treatment, adding an oxidizing treatment system and passing denitrified treated flue gas through the oxidizing treatment system, whereby carbon monoxide in the flue gas is converted to carbon dioxide. The heat generated from the process is directly used to raise the temperature of the flue gas before entering the denitrification unit, reducing or even eliminating the process of raising the temperature of the flue gas by heating with an external fuel. To achieve the purpose of raising the flue gas temperature for denitrification treatment, saving or even eliminating the use of fuel, while treating the carbon monoxide in the flue gas, the environmental pollution caused by the flue gas is reduced, and the secondary pollution in the flue gas treatment process is also reduced or even eliminated.

EFFECT: group of inventions ensures purification of flue gas with several pollutants.
