Magnesium Oxide for Desulfurization

The primary by-product of magnesium oxide for desulfurization in power plants is magnesium sulfate, because the reaction product of flue gas desulfurization is magnesium sulfite and magnesium sulfate, and the comprehensive utilization value is high. On the one hand, we can carry out forced oxidation to produce magnesium sulfate, and then sell it by concentration and purification to produce magnesium sulfate heptahydrate. On the other hand, the advantage of desulfurization in power plants is that the capital cost is low, the operation cost is low, and the desulfurization effect can be as high as 98% or more. Therefore, the magnesium oxide desulfurization technology will gradually become more widely used.   High desulfurization efficiency: Magnesium oxide is much larger than the calcium-based desulfurizer in terms of chemical reactivity, and the molecular weight of magnesium oxide is smaller than that of calcium carbonate and calcium oxide. Therefore, t…
