DeNOx System

LAB solutions ensure treatment of Nitrogen Oxydes (NOx) by :

  • Catalytic systems (SCR) with control and limitation of ammonia (NH3) slip.

 



SCR - CataLAB™

CataLAB™ consists in the reduction of Nitrogen Oxides (NOx) by injection of ammonia or urea (liquid) upstream a catalyst.

CataLAB™ is a SCR DeNOx process with successive layers of honeycomb or plates catalysts.

Its position in the flue gas cleaning system can be as follows:

  • Downstream a de-duster before acid gases removal : low dust SCR
  • Downstream acid gases removal in clean gas conditions : tail-end SCR
  • At lower temperature downstream an efficient dry system : cold SCR (with regeneration if needed)

NOx removal on CataLAB™ is easily combinable with catalytic destruction of dioxins/furans and/or treatment of CO.

All CataLAB™ units are designed with control of ammonia slip under most stringent regulations.
