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, the desulfurization efficiency of magnesium oxide is higher than that of the calcium method under the same conditions. Under normal circumstances, the desulfurization efficiency of magnesium oxide can reach above 95-98%, while the desulfurization efficiency of limestone/gypsum method is only about 90-95%.
Low investment cost: Since magnesium oxide has its unique superiority as desulfurization itself, the structural design, the amount of circulating slurry, the overall scale of the system, and the power of the equipment can be correspondingly small, so that the entire desulfurization system The investment cost can be reduced by more than 20%.
Low operating costs: The main factors determining the operating costs of the desulfurization system are the consumption of desulfurizers and the cost of water and electricity. The price of magnesium oxide is higher than that of calcium oxide, but the amount of SO2 magnesia removed is 40% of calcium carbonate. The ratio of liquid to gas is a very important factor in terms of power consumption such as water and electricity. It is directly related to Desulfurization efficiency of the entire system and operating costs of the system. For the limestone gypsum system, the liquid-to-gas ratio is generally above 15 L/m3, and the magnesium oxide is below 7 L/m3, so that the magnesia desulfurization process can save a large part of the cost. At the same time, the sale of by-products of magnesium oxide can offset a large part of the cost.
Reliable operation: The biggest advantage of magnesium desulfurization relative to calcium method is that the system does not have the problem of equipment fouling and blockage, which can ensure the safe and effective operation of the whole desulfurization system. At the same time, the pH value of magnesium method is controlled between 6.0 and 6.5. The corrosion problem of equipment under certain conditions has also been solved to some extent. In general, magnesium desulfurization has a very strong guarantee for the safety performance in practical engineering.
