Severe unexpected localized corrosion of a 316 stainless steel autoclave occurred during investigating Type H Portland cement stability in 0.16 M CaCl2 + 0.02 M MgCl2 + 0.82 M NaCl brine in contact with supercritical CO2 containig 4% O2. The system operated at 85oC and pressure of 29 MPa. However no corrosion was observed in the same type autoclave being exposed to the same environment containing Type H Portland cement cylindrical samples also operating at pressure of 29 MPa but at 50oC. The operation time for the 85oC autoclave was 1272 hours (53 days) and while that for the 50oC autoclave was 1584 hours (66 days). Debris were collected from the base of both autoclaves and analyzed by X-ray diffraction (XRD). Corrosion products were only identified in the debris from the 85oC autoclave. The chemical compositions of the service environments after the specific hours of operation were analyzed by inductively coupled plasma (ICP) at 25oC. The cement samples were analyzed before and after the exposure by ICP and X-ray fluorescence (XRF) methods. Also optical microscopy was used to estimate an extent of degradation.
