Magnesium Hydroxide for Flue Gas Desulfurization  

Magnesium Hydroxide for Flue Gas Desulfurization

The reaction mechanism of magnesium hydroxide flue gas desulfurization method is to use magnesium hydroxide and sulfur dioxide dissolved in water to carry out acid-base neutralization reaction of sulfite solution, and then the magnesium sulfite and magnesium sulfate generated after recycling sulfur dioxide for reuse or forced oxidation of all of them into magnesium sulfate made of sulfate. More stable magnesium sulfate can be prepared by further oxidation of magnesium sulfite by by-product.   Main advantages of the process: As a desulfurizer, magnesium hydroxide is one of the magnesium base wet desulfurization process, so the method has various advantages of magnesium base desulfurization process. High desulfurization efficiency. In terms of chemical reaction activity, magnesium hydroxide is far greater than calcium based desulfurizer. Generally, the desulfurization efficiency of magnesium hydroxide can reach more than 9…
