The biggest disadvantage: MgO desulfurization method is more complex and the miscellaneous cost is higher.






Characteristics of MgO desulfurization:






1. High desulfurization efficiency. Magnesium oxide is much more active than calcium based desulfurizer in chemical reaction, and the molecular weight of magnesium oxide is smaller than that of calcium carbonate and calcium oxide.






2. Reliable operation. The biggest advantage of magnesium desulfurization over calcium desulfurization is that the system will not have the problem of equipment scaling and blocking, which can ensure the safe and effective operation of the whole desulfurization system, and the pH value of magnesium desulfurization is controlled between 6.0 and 6.5.
