PROCESSING METHOD FOR EXHAUST GASES FROM PLANTS FOR IRON AND / OR SYNTHETIC GAS PRODUCTION Russian patent published in 2017 - IPC C21B13/00 

FIELD: physics.

SUBSTANCE: invention relates to a method and a plant for treating the exhaust gases (4) from the plants (32, 33) for iron and / or synthetic gasproduction. Wherein the first partial flow (51) of the exhaust gas or synthetic gas after the water and / or steam (10) addition is subjected to at least a partial conversion of CO into CO₂, and the exhaust gas (4) or synthetic gas, then is treated to separate CO₂. To be able to control the variable ratio H₂/CO in the exhaust gas or synthetic gas is provided, that the other partial stream (52) of the exhaust gas or synthetics gas are not subjected to conversion of CO into CO₂, but separately from the first partial flow (51), it is treated to separate CO₂.

EFFECT: invention is an additional method of treating the exhaust gases from plants for iron and / or synthetic gas production.
