Disposal of desulfurization by-products
Thread Content
Our company uses the double-alkali method for desulfurization, and the disposal of the by-products resulting from this process has become a major challenge. I invite environmentalists to share their insights.
The key issue with desulfurization by-products is dehydration; after dehydration, they can be sent to cement and building materials companies, or used as soil conditioners.
It’s impossible to handle it; there’s gypsum piled up everywhere, and on top of that, the gypsum produced by the double-alkali method is of even lower quality! Go away, headache.
That’s correct; the best use for desulfurization by-products is as building materials. Using them for other purposes is more difficult and requires greater investment.
For paving or filling, in the wet method, gypsum can be produced if the quality is good.
By-products are basically discarded; if they were to be recycled, the cost would be too high, and the owners are unwilling to bear it.
