Treatment of alkali slag from alkaline washing of sulfur exhaust gases
Thread Content
During sulfur alkali leaching, what should be done if the amount of alkaline residue is too high?
What are the main ingredients! Let’s talk about the specific process!
Are you asking about how to deal with alkaline slag, or about solving the problem of its large quantity?
Flue gas alkaline washing is intended for the desulfurization of exhaust gases; the by-product obtained is sodium sulfate-containing brine, which, depending on the conditions of the wastewater, is sent to the wastewater treatment system.
The specific ingredients and manufacturing process need to be clearly stated; otherwise, it will seem very vague
The components include sodium sulfate, sodium bisulfate, sodium bisulfite, and sodium sulfite. The process involves a Claus recovery process based on partial combustion, high-temperature thermal reactions, and two-stage catalytic reactions
The alkali consumption is high, and the alkaline slag wastewater treatment plant cannot handle it
The alkali content should be very low; it’s mainly salts. The alkali content in our alkaline cleaning solutions is generally around 0.1%
