Ammonium Sulfate / Ammonia-based FGD
Proprietary to and Patented by Marsulex Environmental Technologies. In the Ammonium Sulfate (AS) process, the absorption of SO2 is accomplished with either anhydrous or aqueous ammonia and converts the captured SO2 into a high value crop fertilizer. This advanced technology provides a unique solution enabling power generators to achieve regulatory compliance producing significant revenues by the sale of AS fertilizer.
Advantages of AS WFGD System
- Ammonia reagent more reactive than limestone and capable of achieving > 98% SO2 removal efficiency
- AS FGD produces high value by-product versus low value gypsum or sulfite waste sludge
- Designed with standard conventional critical equipment redundancy
- AS water soluble chemistry prevents any internal build-up versus scaling potential with limestone scrubbing
- Lower overall operating cost through elimination of waste product disposal and high value by-product production.
Benefits of Ammonium Sulfate WFGD
- Economics enhanced with low cost, high sulfur fuels
- Reduces / eliminates solid and liquid waste disposal requirements / costs
- Valuable AS fertilizer provides revenue stream
- No CO2 greenhouse gas is produced in the AS WFGD process (unlike limestone/lime WFGD)
