    Abstract: In a method and an apparatus for separating at least one gaseous component from a waste gas of an installation for producing liquid pig iron, liquid primary steel products or sponge iron, in a first step, a stream of the waste gas passes through at least one adsorption separator at a first pressure, whereby the gaseous component is largely separated from the waste gas and, in a second step, the gaseous component is largely removed from the adsorption separator at a second pressure, which is lower than the first pressure. The method and apparatus are maintenance-free, cause low investment and energy costs and has a lower space requirement by a method in which the second pressure or the desorption pressure is generated by at least one jet pump, which is fed a stream of a propellant gas at a third pressure, which is higher than the second pressure.
