Effect of heat treatment of injection pipe steels on the formation of local corrosion in CCS-environment
- When engineering a Carbon Capture and Storage site (CCS) local corrosion (pitting) of the injection pipe steel may become an issue when emission gasses from oxyfuel power plants are compressed into deep geological layers. This highly corrosive environment arises when the flue gasses, mainly composed of CO2 , are injected into saline aquifer water. Immediately carbonic acid is formed causing corrosive attack of the injection steels. The influence of heat treatment on the local corrosion resistance was demonstrated in laboratory experiments at 60 °C and ambient pressure for three steels X46Cr13 (1.4034), X20Cr13 (1.4021) and X5CrNiCuNb16-4 (1.4543) under a similar liquid corrosive environment as found at a geological onshore CCS-site in the Northern German Bassin.
