Solid waste residue produced by soda ash desulfurization
Thread Content
What is the use of the solid waste residue produced after soda ash desulfurization?
What process do you use for desulfurization? Dry method, wet method? We use TRS iron-cobalt-nickel catalyst for desulfurization. The waste residue contains about 10% elemental sulfur. The amount is not large, but it is troublesome to handle. Of no use
It is wet soda ash liquid desulfurization, and the waste residue obtained contains about 70% sodium sulfate. I wonder whether it can become a renewable resource or which industry can use it.
Haha produces large soda, sodium thiosulfate,
Your question is very good. Sodium sulfate can be reduced to sodium carbonate and reused in the desulfurization system, so you don't need to increase the amount of soda ash. At the same time, sulfate anhydride is produced. The market for anhydrous sulfate is still okay. If you are interested, please contact qq734534624
Reduce sodium sulfate to sodium carbonate? This is difficult.
It is not difficult, but if the process route is unreasonable, it will not be economical. It is very easy to implement and can be done at room temperature. It would be more convenient if the desulfurization is reused, and it can be directly made into baking soda. If interested please contact. qq734534624
