1.Magnesium Hydroxide For Heavy metal removal reacts rapidly with SO₂ to form magnesium sulfite (MgSO₃) or magnesium sulfate (MgSO₄), with a desulfurization efficiency of over 90%, making it particularly suitable for the treatment of medium and low sulfur flue gas. 2.Compared with the limestone method, Non-corrosive Magnesium Hydroxide has a higher solubility, requires a smaller volume of absorption tower, and has no risk of gypsum scaling, reducing equipment clogging and maintenance costs. 3.Non-corrosive Magnesium Hydroxide can be used in wet (spray tower) and semi-dry (spray drying) desulfurization processes, and can also be combined with limestone to enhance the performance of traditional FGD systems. 4.Non-corrosive Magnesium Hydroxide generates soluble magnesium salt (MgSO₄), without solid waste residue, which can be directly discharged or recycled (such as for fertilizer preparation), without secondary pollution. 5.Non-corrosive Magnesium Hydroxide Low energy consumption, less equipment investment, long service life, and better economic performance in long-term operation

Flue gas desulfurization Grade magnesium hydroxide is an effective alkaline reagent used in wet and semi-dry flue gas desulfurization (FGD) systems to remove sulfur dioxide (SO₂) from industrial exhaust gases (e.g., coal-fired power plants, waste incinerators, and metal smelters).


1. How Flue gas desulfurization Grade magnesium hydroxide Works in FGD

  • Reaction with SO₂:

Mg(OH)2+SO2→MgSO3+H2O

MgSO3+12O2→MgSO4 (Oxidation in wet systems)

  • End products: Magnesium sulfite (MgSO₃) or sulfate (MgSO₄), both water-soluble and easily managed.

  • Magnesium Hydroxide For Heavy metal removal Compared to Limestone (CaCO₃) FGD:

  • Higher solubility → Faster reaction, smaller absorber size needed.

  • Less scaling risk (unlike gypsum-forming limestone systems).

  • Lower slurry viscosity → Reduced pumping energy.


2. Advantages of Flue gas desulfurization Grade magnesium hydroxide in FGD

√ High Efficiency – Non-toxic Magnesium Hydroxide Reacts quickly even at low SO₂ concentrations.
√ Compact Systems – Non-toxic Magnesium Hydroxide Requires smaller scrubbers than limestone.
√ Less Scaling – No hard sulfate scales (e.g., gypsum) that clog equipment.
√ Wastewater-Friendly – Non-toxic Magnesium Hydroxide Byproducts (MgSO₃/MgSO₄) are soluble, simplifying disposal.
√ Retrofit-Friendly – Non-toxic Magnesium Hydroxide Can replace or supplement limestone in existing FGD systems.


3. Common FGD Process Configurations

A. Wet Scrubbing (Magnesium-Enhanced Lime/Limestone FGD)

  • Process: Mg(OH)₂ slurry absorbs SO₂ in a spray tower.

  • Byproduct: MgSO₄ solution (can be crystallized for sale or discharged).

  • Best for: Large coal-fired plants needing high SO₂ removal (>95%).

B. Semi-Dry (Spray Dryer Adsorption)

  • Process: Mg(OH)₂ slurry is atomized into hot flue gas, drying to a powder while capturing SO₂.

  • Byproduct: Dry MgSO₃/MgSO₄ collected in filters.

  • Best for: Small-to-medium boilers, waste incinerators.


Conclusion

Magnesium Hydroxide For Heavy metal removal is a high-efficiency, low-maintenance alternative to limestone in FGD, especially where space, scaling, or wastewater issues are concerns.
