DeNOx SCR (Selective Catalytic Reduction) and SNCR (Selective Non-Catalytic Reduction) systems are advanced technologies designed to effectively reduce nitrogen oxide (NOx) emissions in industrial processes.

DeNOx SCR and SNCR Systems: features and benefits offered

  • High abatement efficiency: reduction of NOx emissions by up to 95%.
  • Operational flexibility: adaptability to different conditions and types of fuels.
  • Environmental compatibility: minimization of the formation of undesirable by-products.
  • Integration with existing plants: possibility of implementation into already operational industrial processes.

    • Principle of Operation of DeNOx SCR and SNCR Systems

    SCR (Selective Catalytic Reduction)

    In this process, a reducing agent (ammonia or urea) is injected into the exhaust gas and, passing through a specific catalyst, converts NOx to nitrogen (N₂) and water vapor (H₂O).

    SNCR (Selective Non-Catalytic Reduction)

    Unlike the SCR system, this process does not use a catalyst. The reducing agent is injected directly into the combustion chamber at high temperatures, causing the chemical reaction that transforms NOx into nitrogen (N₂) and water vapor (H₂O).

    Typical applications and target sectors

    DeNOx SCR and SNCR systems find application in numerous industries, including:

  • Chemical industry
  • Pharmaceutical sector
  • Oil & Gas
  • Waste treatment
  • Steel industry
  • Cement production
  • Metal industry
  • Energy production
  • Glass industry

    • These sectors benefit from the high NOx abatement efficiency, improving environmental sustainability and ensuring compliance with current regulations.
