Abstract
A method and a system for treating waste gases () from plants () for pig iron production, wherein a first sub-stream () of the waste gas is subjected to an at least partial conversion of CO into COafter the addition of water and/or water vapor () and the waste gas () is then subjected to COcapture. To be able to set a variable H/CO ratio in the waste gas, a further sub-stream () of the waste gas is not subjected to a conversion of CO into CO, but is subjected to COcapture separately from the first sub-stream ().
