Surface Studies of HSLA [high strength low alloy] Steel after Electrochemical Corrosion in Supercritical CO{sub 2}-H{sub 2}O Environment

OSTI ID:1038059
Corrosion resistance of pipeline materials for transporting coal combustion produced supercritical CO{sub 2} from power plants to sequestration sites has not been fully determined. Although pipeline materials are resistant to corrosion in pure supercritical CO{sub 2}, cleaning costs of combustion produced CO{sub 2} streams from impurities such as H{sub 2}O, O{sub 2}, SO{sub 2} are too high, making sequestration of pure CO{sub 2} streams unfeasible. Impacts of the H{sub 2}O, O{sub 2}, SO{sub 2} impurities on pipeline corrosion must be determined. Filling Up This Technological Gap requires studying effects of H{sub 2}O, O{sub 2}, SO{sub 2} concentrations on pipeline.
