Have you installed an FGR system to reduce your carbon emissions?

Have you inadvertently increased corrosion potential?

Is your export gas still compliant with the pipeline’s entry specifications?


Qa3 have identified a route for oxygen (O2) ingress which has not been previously considered. Nitrogen, used within low pressure systems on both onshore and offshore facilities, may contain up to 5% oxygen. This oxygen rich nitrogen is introduced into the gas process as a consequence of the installation of green FGR systems resulting in elevated oxygen concentrations in the processed gas.

If you are running an FGR system, we urge you to read our white paper via the below link:
