Selective Catalytic Reduction (SCR) – Peerless Emissions Control

Selective Catalytic Reduction (SCR) - Peerless Emissions Control


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%.

Peerless Emissions Control patented Direct Injection SCR System is an innovative delivery, metering and injection system designed to reduce NOx and CO emissions using substantially less auxiliary load compared to a traditional SCR system.

Our Peerless Emissions Control brand TRIM-NOx® XL SCR injection module automatically injects a urea or ammonia-based reagent into the exhaust gas of a boiler, furnace, turbine or IC engine to reduce NOx emissions. Each module is engineered to optimize efficiency, performance and reliability while meeting stringent environmental standards.

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

Features & Benefits
