YiranMagnesium oxide desulfurization methodThe process mainly uses magnesium oxide powder as a desulfurizer for flue gas desulfurization. Magnesium oxide powder reacts with water to obtain magnesium hydroxide slurry. The slurry undergoes acid-base neutralization reaction with sulfur dioxide in the flue gas to form magnesium sulfite. Aeration oxidation generates by-product magnesium sulfate for desulfurization and denitrification.Characteristics of magnesium oxide desulfurization process:

1Magnesium oxide desulfurization methodMature technology, reliable operation, less prone to scaling and blockage, and easy maintenance;

2. Magnesium oxide method has strong desulfurization reaction activity and high desulfurization efficiency;

3. The process system is simple, the investment is low, and the footprint is small: the magnesium oxide desulfurization method has a small structural design of the desulfurization absorption tower, the size of the circulating slurry, the overall scale of the system, and the power of the equipment;

4. Low consumption of desulfurizer, low liquid to gas ratio, and low power consumption;

5. Magnesium oxide resources are abundant and easy to obtain;

6. Low operating costs: Although the price of magnesium oxide is slightly higher than that of calcium oxide, the amount of magnesium oxide used to remove the same SO2 is less than that of calcium carbonate; And the sale of by-products from the magnesium oxide process can offset some of the production and operating costs;

7. Reliable operation: Magnesium oxide desulfurization is less prone to equipment structural blockage, safe and reliable. The pH value control of magnesium desulfurization is accurate, and equipment corrosion is minimal.
