Magnesium Oxide for FGD Of Steel Plant and Power Plant Products > Calcined Brucite Powder (Magnesium Oxide)
Commercial name: Magnesium OxideOther name: Calcined Magnesium Oxide, Magnesium Oxide, Magnesia usta, Calcined magnesia, Magcal, Maglit, elastomag, marmag, MgO
Key chemical content: MgO
Producing method: Brucite is heated at 750~1100℃ and then being grinded into powders.
Application: Flue Gas Desulfurization
Principle:
Sulfur Dioxide reacts with Magnesium Oxide seriflux in the smoke and then becomes Magnesium Sulfite.(1)MgO+SO2+H2O→MgSO3+H2O
Magnesium Sulfite in the absorption tower reacts with air conveyed by oxidation air blower, and becomes Magnesium Sulfate. The reaction between HSO and Oxygenous is the key reaction.
(2)MgSO3+O2+H2O→MgSO4+H2O
