| Abstract Scope |
Many industrial processes involve carbon capture, utilization and storage (CCUS). Carbon steel pipelines are one of the most effective methods for transporting captured CO₂ to storage facilities. However, the CO₂ stream may contain various impurities, such as H2O and NOx, which can cause severe corrosion in steel pipelines. While there is extensive literature on steel corrosion related to CCUS applications, key gaps remain in understanding the role of metallurgical factors. The current project investigates the role of microstructure on the corrosion behavior of an X65 pipeline steel in CCUS-relevant environments. X65 steel samples were exposed to a pressurized CO2 environment containing H2O, and the resulting corrosion products are being characterized through electron microscopy, X-ray diffraction, secondary ion mass spectroscopy, and Raman spectroscopy to reveal the microstructural effects on corrosion mechanisms. |
