DeNOx engineering solutions for industrial flue gas treatment

AB Clean Air Solutions supports plant operators, EPC contractors and technology partners with tailored concepts for NOx reduction — including SCR systems, catalytic filtration and advanced Wet NOx Removal solutions.

Each DeNOx project begins with a detailed evaluation of process conditions, temperature windows and existing flue gas treatment systems. Based on this analysis, AB Clean Air Solutions develops customized engineering concepts, including:

  1. Selective Catalytic Reduction (SCR)
  2. Catalytic ceramic filtration
  3. Wet NOx Removal (WENOx) and multi-pollutant flue gas treatment
  4. SNCR and optimized urea or ammonia injection systems
  5. Retrofit engineering with minimized pressure drop
  6. Modular reactor and catalyst cassette concept


Engineering solutions can be adapted to different temperature ranges and pollutant profiles:

  • NOx treatment: 180°C → 450°C
  • Acid gas removal: 140°C → 500°C
  • Particulate removal: 150°C → 900°C

All systems are individually tailored to the respective industrial application.
