SELECTIVE CATALYTIC REDUCTION
SCR technology converts flue gas NOx to nitrogen and water by cataltically promoted reaction in the presence of reducing agent such as ammonia, urea, etc. SCR technology offers an optimal and effective solution to control Nitrogen oxides (NOx) emissions during combustion processes.
Selective catalytic reduction principle
The NOx reduction reaction takes place on the catalyst surface. Before entering the catalyst layer the ammonia is injected and mixed with flue gas:

SCR DeNOx process
SCR DeNOx process is inovative, environmentally friendly and effective solution to reach the requested performance at an optimised cost.
DeNOx Honeycomb Catalyst
Honeycomb catalysts consist entirely of catalytically active materials (titanium dioxide, vanadium oxides, tungsten oxides) and commonly are used in low dust applications.
High specific surface area
High activity in low-dust flue gases
Variable pitch and length
Low-dust flue gas applications (<10g/M3)
DeNOx Plate Catalyst
Plate catalysts consist of catalytically active material rolled onto stainless steel mesh. The catalyst plates are located in element frames that are installed in a steel module.
High erosion resistance
Variable pitch
Low pressure drop
High flue dust applications (<100g/M3)
Benefits of our SCR DeNOx Catalysts
Custom Design
All our catalysts are specially designed and manufactured to meet our customer’s requirements. We help you to maximize your reduction of NOx emissions while providing a cost effective solution.
Low Pressure Drop
Our products are known by providing the lowest possible pressure drop when compared to competitive designs. Lower pressure drop means higher system efficiency and better overall performance.
High Catalytic Activity
Our SCR DeNOx catalysts provide high NOx destruction at medium range operating temperatures. High activity, poison resistant formulations means reduction of nitrogen oxide emissions with less catalyst volume – less volume means lower capital cost. NOx reductions over 90% are common and in some applications over 98% reduction can be achieved.
Poison & Sulfur Resistant
Many years of experiance in catalyst research and production allow us to provide the most durable product for your application. Our products will provide a long life and tolerate aggressive process conditions allowing extended intervals between product replacement.
