In this study, the corrosion behavior of N80 steel exposed to 80 bar supercritical CO2 and 0∼15 H2S environments was investigated by weight loss test, surface analysis, water chemistry simulation, thermodynamic kinetic calculations. The results show that a very low pressure 0.004 in environment boosts rate steel, whereas is considerably reduced with further increasing pressure. variation largely depends on changes cathode process overall protectiveness product film caused H2S. As rises,...
The novel Cr-containing low alloy steels have exhibited good corrosion resistance in CO₂ environment, mainly owing to the formation of Cr-enriched film. In order evaluate whether it is applicable and H₂S coexistence conditions, behavior low-chromium CO₂-H₂S environment with high pressure temperature was investigated using weight loss measurement surface characterization. results showed that P110 steel suffered localized both 3Cr-P110 5Cr-P110 general corrosion. However, rate highest among...
Many efforts have been made to pursue low‐cost and efficient electrocatalysts for the hydrogen evolution reaction (HER), which is important real water splitting applications. Herein, a 3D cathode designed synthesized by in situ grafting MoS 2 nanosheets on carbon fiber felt (CFF) framework. As HER catalyst, effective atom adsorption activity due their uniform distribution CFF Meanwhile, framework facilitates electrolyte penetrate into inner space accelerate electron transfer, leads drastic...
The present study explored the electrochemical behavior of UNS S32750, a super duplex stainless steel which was not commonly researched in previous studies. effect bicarbonate ( ) and sulfate on S32750 chloride (Cl − solution investigated using potentiodynamic polarization, scanning electron microscope (SEM), impedance spectroscopy (EIS), Mott‐Schottky analysis. electrochemistry shows that with addition , pitting potential increased passive current density decreased, indicating or can reduce...
Abstract The role of O2 in CO2 corrosion and erosion-corrosion was investigated using high temperature pressure autoclaves, more research methods material surface such as SEM, XRD, EDS etc. were used. results suggested that under static conditions, the morphology pure uniform corrosion, when added, it translated into pitting rate increased. Fe2O3, Fe3O4, FeCO3 main products CO2-O2 environments. potentiodynamic sweeps showed potential increased by 41mV vs. Ag/AgCl current density 300%. When...
Purpose This paper aims to explore the influence of CO 2 partial pressure, flow rate and water cut on N80 steel corrosion behaviors in displacement process oil glutenite reservoir by injection. Design/methodology/approach A self-made 3 L high-temperature high-pressure autoclave was used conduct simulation experiments different pressures, rates (the independently developed mixing approach can ensure uniform experiments). Techniques like weight loss surface analysis were analyze under...
The corrosion behavior of N80 steel in Multiple thermal fluid environment containing O 2 and CO was analyzed by Scanning Electron Microscopy (SEM), Energy-dispersive Spectrometry (EDS) X-ray Diffraction (XRD) techniques. results showed that, the products formed on double layer structure. outer are loose porous, providing little protection. inner mainly FeCO 3 crystals, a small amount Fe FeOOH composition. formation oxide film destroyed integrity layer, resulting localized corrosion. During...
Abstract During offshore oil production, O 2 could be introduced into the multiple thermal fluid, and temperature of wellbore can reach up to 200°C, which may result severe corrosion tubing. However, mechanism downhole pipes in such aggressive environment remains unclear high-temperature high-pressure CO -O -H mixed environment. Herein, we investigated behaviour N80 steel with different temperatures The influence on composition structure product film was characterized by scanning electron...
The stress corrosion behavior of X65 steel in water-saturated supercritical CO2 streams with various impurities was explored. demonstrates a significant acceleration effect on the corrosion, especially localized which mostly depends impurity type. O2 scarcely raises SCC susceptibility steel, whereas SO2 and NO2 greatly enhance its due to their strong effects. process SO2-containing environment is dominated collectively by local anodic dissolution, hydrogen embrittlement stress, while couple...
