METHOD FOR CLEANING FLUE GASES FROM ACIDIC COMPONENTS Russian patent published in 2023 - IPC B01D53/46 C01F11/22 

FIELD: gas cleaning.

SUBSTANCE: complex treatment of various gaseous emissions from industrial production, in particular flue gases. The method for cleaning flue gases from CO₂, CO, NO₂, SO₂ includes pumping the stream of gases being cleaned through a container with a liquid reaction medium, separating and subsequent disposal of the formed by-products. It also includes the regeneration of the spent reaction medium by oxygen saturation and the recirculation of the regenerated medium for pumping. As the reaction medium, a 0.02-2.0 M aqueous suspension of calcium fluoride saturated with oxygen is used.

EFFECT: carrying out the gas purification process in a non-aggressive medium, simplifying the processes of separation and disposal of the resulting by-products.
