Ammonia base FGD
In Ammonia-based FGD process, ammonia with high reactivity is used asabsorbent to capture SO2 in the Flue gas, and the by-product of the process isammonium sulfate fertilizer.
Ammonium sulfate solution is refined through concentration, crystallization, solid-liquid separation, drying to obtain ammonium sulfate fertilizer.

SO2 emission≤35mg/Nm3
PM emission ≤5mg/Nm3
Ammonia recovery≥99%
SO2 removal efficiency＞99%
Performance
No Solid Waste——By-product Ammonium sulfate is fertilizer with wide market
No Waste Water——Meeting the requirement of ZLD
Technical Advantages
Ammonia is an absorbent with high reactivity, SO2 removal efficiency over 99% can
be achieved.
Excellent adaptability, can be applied to treat flue gas with SO2 concentration
ranging from 300 to 30,000 mg/Nm3
Achieving ultra-low emission, the emission level of natural-gas generators on SO2
and PM can be achieved
Technical Advantages
Resource recovery, 1 ton ammonia usage removes 2 ton SO2 and produces 3.8
ton ammonium sulfate fertilizer
Low operating cost, 50%-100% lower than the limestone-gypsum process, or
even generating profits.
Technical Advantages
Zero CO2 is generated in the process; in the limestone-gypsum process, 0.7 ton
CO2 will be generated for 1 ton SO2 removal
Meeting the low SO2 concentration requirement of the Carbon Capture and
Storage (CCS) system, the SO2 emission can be controlled to lower than 2 ppm
