Effect of H₂S/CO₂ Pressure on the Corrosion Behaviors of L360QCS in the Environments Containing Elemental Sulfur

Abstract:

The weight-loss method was used to study the effect of H₂S/CO₂ pressure on the corrosion behaviors of L360QCS in the environments with the existence of elemental sulfur and H₂S/CO₂. The morphologies, compositions and structure of corrosion products formed at different partial pressures were studied by the means of SEM, EDS and XRD techniques. The results show that the existing of H₂S/CO₂ increases the corrosion rate sharply and the corrosion rate increase dependence on H₂S/CO₂ pressure. At low gas pressure the production is mainly cubic FeS crystal while that is square FeS crystal at high pressure.
