Oxidation Catalyst Retrofit
To address ever-tightening emissions regulations across the globe, INNIO Group continuously researches and develops solutions that help you achieve regulatory compliance.

Upgrade for:
What can this upgrade do for you?
- Complete OEM solution
Our consultants perform a thorough plant review to help ensure that the upgrade implementation meets the latest formaldehyde and CO emission requirements (upgrade vs. shorter catalyst exchange interval). All upgrade implementations are fully tested and validated. - Improved flow
Homogeneous flow distribution enables a longer catalyst life.Highly flexible configurations
With our design, we have the flexibility to adapt the installation position based on your specific requirements. - High efficiency
The low-pressure drop design curbs power deratings, which can occur in higher ambient temperature environments. - Reduced installation effort
Thanks to the compact system dimensions and the use of existing components, the upgrade package requires only minor modifications to the system. The oxidation catalyst can be easily installed from the outside. - Service agreement coverage
Your new or existing maintenance agreements can be extended to include the oxidation catalyst upgrade package
How we get you there?
This package helps you meet the latest regulations, including formaldehyde requirements of the federal/state working group for immission control in Germany (Bund/Länder-Arbeitsgemein-schaft für Immissionsschutz, LAI) with as low as 20 mg/Nm³ at 5% O2-dry and formaldehyde incentive. Based on your specific power plant design, the upgrade package is available in a basic configuration or with additional add-on options as required
Basic package:
— Comprehensive design review to determine your plant’s ability to mount additional catalyst material as well as to evaluate pressure drop, flow, and engine full-load capability related to the engine control’s reserve
— Improved oxidation catalyst material for longer part life (design product life cycle up to 16,000 operating hours)
— Mounting materials as required (seals and screws)
— Commissioning
— Updated OEM documentation
Additional options:
— New flow-improved and space-enhanced catalyst chambers
— Measurement devices (delta-p, temperature in/out)
> Changes to electrical hardware inside the control cabinet
> Modifications to DIA.NE software controls
— System component installation and integration with the existing power plant
> Mechanical components including panels, support structure, piping changes, and compensator
> Electrical components including hardware mounting, wiring, and testing
— Comprehensive verification and testing of upgrade package integrations
— Turbocharger upgrade for reduced operational impact of additional backpressure
— Third-party emissions measurement analysis
Out of scope:
— Any permit changes
— Civil works (with the exception of the above optional add-on for the catalyst chamber support structure)
