Effect of H2S concentrations on corrosion failure of L245NS steel in CO2-O2-H2S system

Effect of One Sulfate-Reducing Bacterium SRB-Z Isolated from Pearl River on the Corrosion Behavior of Q235 Carbon Steel

“…In the high-resolution O 1s spectrum, two peaks located at 531.6 and 534.6 eV corresponded to SO 4 2− (SO 3 2− ) and organic O, respectively [38,39]. Finally, the high-resolution S 2p spectrum revealed that three peaks centered at 162.3, 163.7, and 164.9 corresponded to FeS y , FeS x (x > y > 1), and S, respectively [40,41]; and the other three peaks centered at 166.7, 168.5, and 169.8 eV corresponded to SO The elemental composition of the cauliflower-like and the network-like produc detected by EDS, as shown in Figure 2. The EDS spectra show that, after the imme corrosion test, an amount of S and Fe elements emerged in the corrosion product i SRB-Z-inoculated medium.…”

Finally, the highresolution S 2p spectrum revealed that three peaks centered at 162.3, 163.7, and 164.9 corresponded to FeSy, FeSx (x > y > 1), and S, respectively [40,41]; and the other three peaks centered at 166.7, 168.5, and 169.8 eV corresponded to SO4 2− and SO3 2− [42]. The results obtained by XPS tests agree with those obtained by EDS.…”

A novel material selection method and application in an aqueous environment containing CO2, H2S, O2 and SO2

“…29,30 Therefore, studying these two environments is highly valuable and provides essential insights for pipeline material selection. 8,[31][32][33][34] It can also be inferred that selecting materials for CO 2 -H 2 S-O 2 -SO 2 environments poses significant challenges.…”

Mechanism and anti-corrosion measures of carbon dioxide corrosion in CCUS: A review

“…Previous research primarily focuses on corrosion mechanism, the selection of corrosion-resistant materials, and the impact of impurities and corrosion behavior in supercritical CO 2 . 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 Mubarak et al. 27 concerned about the corrosion of oil and gas well casing and tubing and corrosion mitigation techniques.…”
