How to handle the filter residue from the liquid sulfur filter?
Thread Content
The filter residue discharged from the liquid sulfur filter in the sulfur-based acid production plant is mainly diatomite, which serves as a filtering aid; in addition, there is also some ash and organic matter, along with a small amount of sulfur. For this portion of the filter residue, our company is now transferring it to the phosphogypsum dump site; I’m not sure how others handle it.
I didn’t pay attention to that; I only know that vehicles come around from time to time to take away this waste. As for what is done with it, I’m not sure – it’s probably taken away for disposal? If it is sulfur, it will be taken to the mineral acid production plant for burning and utilization
Sold to pyrite-based acid plants for blending in combustion; in high demand.
Co-firing, 60-70% sulfur content
Co-firing is more suitable for manufacturers that produce acid from minerals; it is more difficult for companies that do not use minerals for acid production.
The filter residue from the liquid sulfur filter can be burned together with sulfur concentrate； It has been used with considerable success in Hongfu Company’s pyrite-based acid production system (by mixing sulfur and the sulfur slag filtered by the liquid sulfur filter into the pyrite!) From energy conservation and environmental protection
There are also those bought for carbon disulfide.
Our factory produces sulfuric acid; do we have any filter residue that can be used for this purpose? I’d appreciate some advice
Hehe, last year when sulfur was in short supply, this stuff was really valuable and people were willing to buy it. But now that the price of sulfur has dropped, the residue left after melting sulfur is no longer of any interest to anyone. We have a pile of it here, and we don’t know what to do with it; we can’t even give it away|
I’m not sure what the sulfur residue content is you’re referring to. If the conditions are suitable, I can handle it for you. If you’re interested, feel free to leave a message; my QQ number is 767593233
General treatment methods: 1. Sell it directly (for purification by recycling manufacturers), 2. Use it in combustion (as a raw material for producing acid from pyrite)
