SCR introduction:
For high Dust Layout, catalyst is between boiler economizer outlet and the air preheater, make the injected ammonia react with the NOx in the flue gas to realize the denitrification.
The effective reaction temperature range is 320℃~400℃, much lower than SNCR;
The most common Chemical reactant (reducing agent) is ammonia, Urea is used recently.
ECOTEC cooperates with HEURTEY PETROCHEM, HALDOR TOPSOE, both of which are international leading technology and service providers, providing entire solutions according to the customers’ need,  
Advanced, customized catalyst;
Smoke fluid model and optimization of process;
Innovative ammonia injection technology, distribution technology and hybrid technology;
Module support structure and sealing system;
Catalyst Testing and Management Services.
Equipment technology:
Why choosing SCR process for denitrification of flue gas:
Currently the world’s most popular technology;
Mature technology;
Low investment;
Low operation cost;
No second pollution.
Why choosing ECOTEC denitrification product:
Unique, controlled three-state pore structure, higher activity and diffusivity;
Void volume is twice the plate and extruded type catalyst, highest specific surface area;
Relatively small volume, low pressure drop;
The lightest weight per volume;
Strong resistance to poisoning, more channels into the catalyst active sites
 Lowest SO2 / SO3 conversion rate;
 Strong thermal shock resistance.
