Modular Airless SCR Systems for Large Engines
- 63 Downloads
Aftertreatment systems for large engines need to cover a wide range of displacements, outputs, fuels and load profiles in wide variety of application contexts and with variable availability of installation space. To meet these needs as economically as possible, Tenneco has developed a modular SCR system.
Motivation and market background
Globally, emissions legislation for combustion engines is becoming increasingly stringent. With the latest initiatives in the marine and stationary sectors, such as IMO III and EPA Tier 4, demand for exhaust aftertreatment is also growing in the large engine segment, i.e. engines with outputs above 560 kW. Selective Catalytic Reduction (SCR) is a robust and proven method of reliably reducing emissions of oxides of nitrogen (NOx) by wide margins in order to achieve compliance with the stringent limits in force or coming into force.
