Solution: What processes are generally used for desulfurizing low-hydrogen sulfide waste gas? Can the Claus oxidation technology be used to reduce 1000 ppm to below 100 ppm?
Based on the gas volume, we have various process options available. If the gas volume is small, iron oxide desulfurization absorption is sufficient. If there is sufficient gas volume, use the wet method or the biological method.
For small gas volumes, the dry method is preferred; for larger volumes, the wet method is used to recover sulfur
Kraus oxidation is used for sulfur production; the process is relatively long and the investment required is high.
I think it is feasible to use a selective oxidation process; one reactor will suffice, and sulfur needs to be recovered.
This is too low; Klaus can’t handle it, so another method has to be used
Who is right after all? I personally would prefer to know if it can be explained in more detail!
By using an oxidation catalyst, sulfur is produced directly; the conversion rate for the reaction H2S+O2——S+H2O is as high as 99.9%. Additionally, besides hydrogen sulfide, what other components are present in your atmosphere? Thank you.
A set of LYSY complexed iron desulfurization methods can handle it; either DF888 or biological methods will work as well.
It’s because your request wasn’t specific enough. The sulfur content in your medium may not be that low, but you need to tell them how much of this gas your factory produces – whether it’s a few thousand cubic meters per year or hundreds of thousands of cubic meters per year. The treatment methods and investment costs vary greatly depending on these figures. Since you’ve provided vague information, it’s difficult to reach any conclusions.
