I’d like to ask the experts! ! How can carbon dioxide be removed from sulfur-containing waste gases without also absorbing substances such as hydrogen sulfide?

What do you mean? Could you describe it in more detail? We can communicate with each other.

It might be difficult to achieve. Since H2S is more reactive than CO2, meaning it is easier to absorb and at a faster rate than CO2, it is logical that H2S is absorbed first. If you want to concentrate acidic gases, it is better to choose absorbing H2S, as it is easier to release it afterward.
This mainly depends on the properties of your solvent; in general, it tends to absorb hydrogen sulfide gas primarily.
