Johnson Matthey Stationary Emissions Control

Stationary Engines

Reduce NOx, CO, Hazardous Air Pollutants and Particulate Matter (PM) from Stationary Reciprocating IC Engines of All Sizes

To reduce NOx and CO, our SCR and CO catalyst systems are engineered for multi-MW engine projects providing turnkey power, including urea supply. Our complete line of pre-engineered SCR and CO systems are packaged for medium power projects. These systems have proven to operate in the harshest environments around the world. Our novel urea injector is designed for plug-free operation regardless of engine duty cycle.

Our Modulex™ line of catalytic converters reduce NOx, CO and HAPs/HC from smaller engines with or without sound attenuation. The Modulex converter is modular in design to allow for different catalyst and flange sizes as well as a hatch for easy access to the catalyst for cleaning or replacement. They meet the most stringent air emission standards.

To reduce PM from stationary diesel engines, our patented CRT® (Continuously Regenerating Technology) is preferred. Our CRT has been installed on millions of vehicles as well as on hundreds of thousands of trucks and buses. It is capable of reducing over 90% of the PM and is widely used in emergency back up diesel generators as well as prime power generator engines. Our CRT(+) is CARB (California Air Resources Board) verified for emergency and prime diesel generators.

Stationary Application

Exhaust monitoring is an area of special importance to us. We can engineer a Continuous Emissions Monitoring System (CEMS) for feed-forward or feed-backward designs or to provide a Parametric Emissions Monitoring System (PEMS) for a more economical approach. To meet specific requirements such as the EPA's RICE NESHAP regulation, Johnson Matthey's HAPGuard™ Monitor helps the operator to insure that the exhaust temperatiure is within the range of 750°F to 1250°F for rich burn gas engines and 450°F to 1350°F for lean burn gas engines. For diesel engines, Johnson Matthey's unique SootAlert® Monitor checks the time, pressure, and temperature of the CRT system, and shows you a green light when the filter is clean, a yellow light when it has begun to accumulate soot and a red light indicating that it is time to regenerate the filter.

Three way – NSCR – TWC catalyst – Rich burn

Two way – Oxidation Catalysts – Lean burn
