SCR-Catalyst Retrofit Package for low NOx emissions requirements

The SCR-Catalyst package is designed for integration to existing natural gas plants to be in compliance with low NOx emissions requirements e.g. new BEMS decree Netherlands NOx <88 mg/Nm3 at 5 percent 02 - dry emission requirement for plants with more than 2 MW thermal input.

What Can an Integrated SCR Catalyst Do For You?

Complete OEM solution.
Optimized SCR-system solution carefully aligned with the engine to minimize trade-offs between low emissions and maximum engine performance.

High temperature resistant catalyst formulation.
In most cases there is no need for installation and integration of an additional exhaust pre-cooler before SCR-system.

Back-pressure optimized design. 
Low pressure drop design to avoid/reduce power deratings at hot ambient conditions.

Compact system dimensions and use of existing components.
Reduce plant re-building efforts and thereby minimize installation cost of the overall solution.

Controls integrated in Jenbacher DlA.NE unit control system. 
Joined control system to optimize interaction between engine and SCR-system. Simple control by utilizing well-known unit user interface.

Remote monitoring and diagnostics.

Service agreement option.
New and existing maintenance agreements can be extended to include the SCR-system.
