How to handle the residue remaining after sulfur filtration in sulfur-based acid production
Thread Content
Dear sea friends, how should the residue remaining after the filtration of liquid sulfur in the sulfur-based acid production process (commonly known as sulfur slag) be disposed of? Let’s discuss some good ways to handle this. With strict environmental regulations in place now, it should still be considered hazardous waste. There used to be companies specialized in dealing with it, but now, due to environmental concerns, such handling is no longer carried out. Some manufacturers also use it in combination with other materials in their sulfuric acid production plants, but others claim that such mixing has an impact on the system, leading to a decrease in yield and electricity generation, as well as affecting the conversion process. What are people’s opinions on this? Thank you!
Given the current environmental situation, the only option is to send it for use in the combustion of pyrite; even if it costs money, it’s still better than sending it to waste treatment plants. Back in the day, a long time ago, it was simply disposed of carelessly.
What kind of filters do you use for sulfur filtration?
