Sulfur has a dark color
Thread Content
Our unit’s sulfur production facility has a capacity of 15,000 tons per year; the sulfur produced recently is of a darker color. I am seeking advice from experts – any suggestions would be greatly appreciated. Thank you!
I’m not sure whether the term \"darkened color\" refers to liquid sulfur or solid sulfur If the liquid sulfur is dark in color and its viscosity increases, it indicates that the temperature of the liquid sulfur is too high. If the color becomes darker due to sulfur fixation, it indicates that there are impurities in the system or that the temperature of the reaction furnace is too low.
If the color becomes darker due to sulfur fixation, it indicates that there are impurities in the system or that hydrocarbon components are present.
Forgot to mention that it darkens due to sulfur fixation, with a slight greenish tint – thank you for your guidance
It may be that the incomplete combustion of certain hydrocarbons in the acidic gases leads to carbon buildup, causing the sulfur to darken
I agree with the person above; too low a temperature in the furnace chamber of the combustion furnace can cause this phenomenon, and it is also related to the composition of the feed gas
OP, do your burners use ammonia? Pay attention to the issue of complete ammonia combustion, as well as whether the system has been properly purged. Wait
