Nitrogen oxides reduction

CataLABTM consists in reduction of nitrogen oxides (NOx) by injection of ammonia or urea (liquid or solid) upstream a catalyst.

CataLAB is SCR DeNOx designed for 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.

LAB has developed new generation of cold SCR, the CataLAB VLT,the Very Low Temperature SCR technology for Waste-to-Energy plants.

Key benefits of CataLAB™:

  • High performances on NOx removal
  • Combination with dioxins/furans and/or CO catalytic destruction
  • High availability and lifetime of catalysts
  • Design combining evolution for stricter regulations
