Total sulfur content after catalytic dry gas desulfurization
Thread Content
1. I’m not sure what the target level for total sulfur content in the dry gas after catalytic treatment is for everyone else – what is the specified limit? Our company has a styrene production facility, and there the required limit is 10 mg/m3; however, we think it’s difficult to achieve this level. At present, the total sulfur content in our gas after treatment ranges between 50–100 mg/m3. 2. Are hydrogen sulfide and other sulfides the main components present in the catalyzed dry gas?
The main component in dry gas is hydrogen sulfide; generally, it is reduced to 10 ppm after removal
If the total sulfur content after desulfurization is 40 mg/m3 and the hydrogen sulfide level is 0, is it still meaningful to increase the solvent circulation rate?
