SCR Systems
Direct Injection
The patented Peerless Emissions Management 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. By eliminating the need for vaporization equipment such as fans and electric heaters, Direct Injection SCR reduces capital and operational costs by 60%.
PEERLESS EMISSIONS
Less Equipment. Lower Costs.
95%+ NOx and CO Reduction.
How Direct Injection SCR Works
The Peerless 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.

Direct Injection TECHNOLOGY
Safer Reagent Options
Peerless specializes in safer alternatives to ammonia, such as urea-based SCR. Direct injection systems are available in both urea and aqueous ammonia configurations, as part of customized SCR systems that also include reverse flow designs.
Direct Injection TECHNOLOGY
Engineered with In-House CFD
Our dedicated in-house computational fluid dynamics (CFD) department utilizes 40 years of industry experience to engineer the best solution for each plant. Through complete integration of reagent delivery, catalyst and system processes, Peerless provides a single-source performance warranty.
Direct Injection Retrofits
Direct injection retrofit and reagent conversion are part of Peerless vaporizer performance services for existing SCR systems. For plants with aging ammonia vaporization equipment, converting to direct injection offers a path to fewer components and lower maintenance.
Direct Injection SCR Benefits
With more than 1,500 SCR units in operation, serving more than 130 GW of power generation capacity and with systems in more than 100 industrial facilities worldwide, Peerless is the most experienced SCR supplier in the industry.
Delivering Measurable Results
Expanded Capacity, Reduced Emissions
At Ingredion’s Argo facility in Bedford Park, Illinois, the plant needed to expand steam capacity by 440 KPPH while meeting NOx below 10 ppm and CO below 50 ppm from 10-110% load. The customer preferred a direct injection system over a conventional vaporizer/decomposition system to save on operating and utility costs. An aqueous ammonia direct injection SCR system, coupled with a multi-pollutant reduction catalyst, achieved NOx below 10 ppm and CO below 10 ppm, a greater than 90% NOx reduction.
Small Footprint, Ultra-Low Emissions
At a New England paper mill, single-digit emissions were required after a production expansion. Peerless installed an SCR system using patented Direct Injection technology, low exhaust gas temperature catalysts and a safe urea reagent system. The retrofit achieved ultra-low emissions across a wide range of production rates, with low operating costs and a small footprint.
