SCR-Catalyst Retrofit

The SCR-Catalyst package is designed for integration to existing pipeline gas plants to help them comply with low NOx emissions requirements. For instance, the Netherlands’ BEMS decree requires NOx <88 mg/Nm³ at 5% O₂-dry emission for plants with more than 2 MW of thermal output.

What can this upgrade do for you?

Complete OEM solution
Enhanced SCR-system solution carefully aligned with the engine to reduce trade-offs between low emissions and increased engine performance
High temperature resistant catalyst formulation
In most cases, no need for installation and integration of an additional exhaust pre-cooler before the SCR system
Back-pressure enhanced design
Low pressure drop design to avoid/reduce power deratings at hot ambient conditions
Compact system dimensions and use of existing components
Lower plant re-building efforts and, therefore, lower installation cost of the overall solution
Controls integrated in Jenbacher DIA.NE unit control system
Joint control system for enhanced interaction between engine and the SCR system. Simple control with 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.

How we get you there?

You can choose between a standardized solution for self-integration to the current plant design (Light package) or a complete customized plant integration from the OEM (Full package).

Light package:
— SCR housing filled with catalyst material
— Dosing system including urea pump panel, air supply and metering panel, dosing valve panel, injector
— Measurement devices (delta-p, T in/out, NOx)
— Electrical hardware changes inside control cabinet
— Software changes to DIA.NE unit control system
— Commissioning
— OEM documentation update

Full package:
— Light package scope
— Mechanical and electrical engineering
— Integration of the system components to the existing plant
> Mechanical: panels, support structure, piping changes,
compensators
> Electrical: hardware mounting, wiring, testing
> Urea system: transfer lines and interconnections
— System checks and test runs
— Turbocharger enhancement to reduce operational impact of back-pressure increase
— Commissioning
— OEM documentation update

Options:
— Urea tank
— Trace heating for urea transfer line
— Scaffolding
— Third-party measurement

Out of scope:
— Any permit changes
— Civil works beyond optional support structure for SCR housing
