Key takeaway: Magnesium oxide flue gas desulfurization (MgO-FGD) is winning share from limestone-gypsum systems across Asia and Europe.
Magnesium oxide flue gas desulfurization (MgO-FGD) is winning share from limestone-gypsum systems across Asia and Europe. In this article we explain the chemistry of MgO + SO₂ scrubbing, why magnesium-based FGD reaches 95%+ SO₂ removal with 30% less reagent circulation, how the byproduct magnesium sulfite/sulfate can be recycled into fertilizer-grade magnesium sulfate, and what purity of industrial magnesium oxide delivers the best lifecycle cost. Includes a reagent consumption calculator example and typical plant configuration.
As a magnesium oxide manufacturer, Magnesium Home supplies FGD-grade MgO with high activity and stable MgO ≥ 90% for desulfurization towers.
