Selective Catalytic Reduction DeNOx
Process Introduction
SCR denitrification technology is the selective catalytic reduction technology, which means that by use of denitrification reducing agent (liquid ammonia, ammonia water, urea, etc.), NOx(mainly NO, NO2) in the flue gas is selectively reduced into nitrogen (N2) and water (H2O) under the catalyst action, so as to achieve the purpose of removing NOx.
Performance And Superiority
DeNOx efficiency: 50%~90%. System availability: >98%.
Flue gas temperature:320~400℃ (high dust arrangement).
SCR pressure lose: < 1000Pa (three layer of catalyst)
SO2/SO3 oxidation: < 1% NH3 escape:<3ppm Catalyst chemical life: 24,000h
Catalyst mechanical life: 10 years
