How to address desulfurization of ammonia water containing hydrogen sulfide?
Thread Content
The ammonia water produced as a by-product in refineries contains hydrogen sulfide, giving it a very strong odor. May I ask how to remove hydrogen sulfide from this ammonia water? What equipment and processes are needed?
Is there a hydrogen sulfide recovery system? It would be easier to handle if it exists

A catalyst can be added to remove hydrogen sulfide while recovering ammonia
The acidity in refineries is removed through stripping; simply send it to the stripping unit for that purpose. Additionally, if the incoming water has a very strong hydrogen sulfide odor, it indicates that the ammonia concentration in the acidic water is insufficient.
