Industrial Applications

What We Do

Carmeuse and our affiliates support the flue gas treatment needs of industrial facilities from End-2-End.

Carmeuse raw materials play a key role in treating flue gas emissions. Our lime and limestone products enable effective flue gas treatment for industrial applications, by helping to prevent acid gases and heavy metals from being dispersed into the atmosphere.

How it Helps

• Wet Flue Gas Desulphurization – In wet FGD applications, flue gas goes into a scrubber, and a shower of lime slurry rains down counter current to the flue gas flow to remove SO₂, HCl & other harmful acid gases. Wet FGD systems have a high efficiency for gas removal and typically use a magnesium-enhanced lime for processing. However, wet FGD systems can also use limestone.
• Dry Flue Gas Desulphurization – An atomized lime slurry is injected into the vessel to react with and remove SO₂, HCl & other acid gases. While the lime is introduced as a slurry, all moisture evaporates in the scrubber, leaving a dry product and eliminating the need for wastewater treatment.
• Dry Sorbent Injection (DSI) – In dry sorbent injection, hydrated lime is injected directly into the flue gas duct to remove SO₂, HCl & other gaseous pollutants, protecting the atmosphere from harmful emissions. When DSI is used before the air preheater, the injected hydrated lime can decrease corrosion by reducing the risk of the sulfur dioxide (SO₂) gas converting to sulfuric acid (H₂SO₄).
• Ash Stabilization & Solidification – Often, lime products can be used to neutralize and stabilize residual incineration ash. When the material cannot be repurposed, lime can be used to solidify and reduce the leachability of the waste for proper landfill disposal.
