Clean Air Systems
Flue Gas Desulphurization (FGD):
Wet & Dry Scrubbers: Industrial scrubbers are tools that can regulate emissions by purifying the exhaust flows, ensuring that hardly any toxic gasses or particulates can escape the building and enter the atmosphere.
A wet industrial scrubber is capable of extracting toxic substances from exhaust gases by the use of a wet material. As flue gas is transferred through the process, this gas is sprayed by the wet industrial scrubber with a special fluid that primarily reacts with the heavier pollutants present in the air. A dry industrial scrubber on the other hand sprays several dry reagents into the exhaust flow. This slurry will either neutralize contaminants, or fully turn them into another substance.
SCR & SNCR: The DeNOx process converts NOx to harmless nitrogen and water vapour by SCR or SNCR applications.
This reaction requires a reduction medium => “NH3, Ammonia
Common reduction mediums for DeNOx plants:
– Anhydrous Ammonia (NH3)
– Aqueous Ammonia solution (NH4OH), typically
– Urea solution
