What is the concentration of magnesium sulfate in the circulating fluid of the magnesium oxide desulfurization tower?

What is the concentration of magnesium sulfate in the circulating slurry of the magnesium oxide desulfurization tower? And what determines the discharge from the magnesium-based desulfurization tower? Is it the liquid level? PH? Serum specific gravity? *e*e
No one is paying attention. I want to produce magnesium sulfate through the oxidation of sulfurous acid; those who are interested can discuss this with me
1. Magnesium sulfite must be oxidized to magnesium sulfate; the concentration of magnesium sulfate should be maintained at 15%-20%, with a desulfurization efficiency of over 97%. 2. The magnesium sulfite concentration should be below 1%; too high a concentration will cause scaling, blocking of nozzles, pipes, etc. 3. With a magnesium sulfate concentration maintained at 15%-20%, it is economically feasible to produce magnesium-sulfur fertilizer using multi-effect evaporation and recrystallization. 4. The current bottleneck is that power plants lack chemical engineering talent and management experience, and they show no interest in recycling magnesium-sulfur fertilizer. 5. I am currently negotiating the use of a BOT operation model to recover magnesium sulfate. 6. Friends who are interested can get in touch with me. qq: 1079586346
What is the BOT operation mode?
May I ask: Has your question been answered? I want to know too!
Magnesium oxide converts to magnesium hydroxide in water, giving it alkaline properties; however, since magnesium hydroxide is an insoluble substance, it exists in a suspended state in water. In other words, in desulfurization water, magnesium hydroxide exhibits alkalinity only under acidic conditions; under neutral conditions, it does not corrode the equipment, and this is the greatest advantage of the magnesium-based desulfurization method. To be precise, magnesium sulfate is soluble; when the suspension becomes clear, it indicates that the amount of magnesium oxide has decreased.
