Omya Idwala SA offers dedicated products for flue gas desulfurization:

• Desulfocarb special selected limestone sorbent
• Reasorb high reactive chalk sorbent

Flue gas desulfurization (FGD) processes are usually categorized in wet and dry or semi-dry systems.

In wet FGD processes flue gas is contacted in a scrubber with a slurry consisting of Calcium Carbonate as sorbent. Dry and semi-dry FGD processes involve injection of the into the furnace or flue gas duct either as solid or slurry-based sorbent.

In wet FGD systems a high degree of SO₂ removal is usually achieved with high level of sorbent utilization. Dry or semi-dry FGD systems are usually exhibit lower SO₂ removal efficiencies because of the short contact time between the flue gas and the sorbent.

Omya Idwala SA with its expertise and wide network of plants offers best-in-class reagents to achieve an removal rate of up to 95% of sulfur dioxide.

Selected limestone, marble and chalk products come with the required purity and precise particle size distribution for FGD application.

Benefits:

• Efficient sulfur elimination
• Improves operating cost
• Comply with emission regulations
• Improve sustainability
• Reduce carbon footprint
