- Selective Catalytic Reduction (SCR) for NOx Emissions



As flue gases are combusted in gas turbines and process furnaces, nitrogen oxide (NOx) is formed. Our Selective Catalytic Reduction (SCR) system is a post-combustion NOx control technology, which injects an ammonia (NH3) based reagent into the flue stream to reduce NOx emissions by up to 95%. Our SCR designs are engineered to optimize efficiency, performance and reliability, while meeting stringent energy standards.

They are adaptable for a wide range of temperatures, exhaust flow conditions, and various types of fuel including:

  • Natural Gas
  • Refinery Gas
  • Coal
  • Biomass
  • Fuel Oils

  • Low Total Cost of Ownership
  • High efficiency with up to 95% NOx emission reduction
  • Minimal life cycle costs with optimal performance systems
  • Reduced assembly time with pre-assembled modular construction
  • Enhanced design for smaller system footprint

  • Adaptable for wide range of temperatures – 350°F to over 1000°F
  • Custom designs
  • Turnkey construction
