How is the mixed salt handled after salt extraction in a coking plant?
Thread Content
After desulfurization at the coking plant, a salt-extraction process was implemented, but this process was not very effective; no decolorization took place, and thiosulfates, sulfates, and thiocyanates were produced. How should this mixture of the three salts be handled? Is there any good way to deal with this?
Prepare the coal blend! Ammonium salts or sodium salts? ?
Hazardous waste can currently only be stored in hazardous waste landfills; there are no better or more economical disposal methods available for now. The legend refers to the miscellaneous salt storage pond of XX Company.
No, it accelerates equipment corrosion when mixed with coal.
Such oxoacids containing low-grade sulfur are extremely difficult to handle; separating them into individual salts is costly, no one wants these mixed salts, and burning them generates large amounts of corrosive smoke. Such material can only be treated as solid hazardous waste.
The sodium salts have already been piled up; can’t they be used in coal blending anymore?
