How to burn and dispose of solid substances with a high sulfur content
Thread Content
There is now a batch of production waste that is similar in texture to asphalt; it contains many different compounds, and the concentration of each component is relatively low. However, its sulfur content reaches 45% (with about 6% being elemental sulfur and the rest in combined forms). How should this material be handled? If incineration is used, the investment in desulfurization and denitrification afterward will definitely be high. So now I’m wondering if there’s any way to separate sulfur oxides from combustion exhaust gases? (Mainly nitrogen oxides, carbon oxides, sulfur oxides, etc.) In this way, sulfur oxides can be converted into sulfuric acid (which can be used oneself) or sulfur can be produced from hydrogen sulfide in industrial waste gases.
What manufacturing process produced it? Let me first transfer it to the sulfur section in the coal chemical industry area to see if that will be helpful
This is waste from the rubber vulcanization accelerator M; aniline, carbon disulfide, and sulfur react under high temperature and pressure, and these are mainly by-products. This is also the biggest problem faced in the production of accelerator M!
After a preliminary look, it is suitable for treatment using the acid production process by incineration, on a dry basis. However, the investment amount will be a bit high. I’m not sure about the specific situation of the poster; you can get in touch with me to discuss it in detail
