文摘

Corrosion resistance (R_P) of X65 steel was investigated in an oil-in-water emulsion containing H₂S and CO₂ at several oil concentrations and different flow regions using a novel emulsion flow loop. One working electrode was mounted in the flow developing region while the other one was mounted in a region where the flow is fully developed. The experimental results show that the addition of CO₂ to an H₂S containing emulsion decreases the corrosion rate. The R_P in the flow developing region is less than that in the fully developed region and it increases with increasing oil concentration. This flow loop is a promising tool for investigating the R_P of engineering materials in a simulated environment similar to that encountered in the petroleum industry.KeywordsCO₂corrosion and wearemulsionflow loopH₂Ssodium thiosulfate (Na₂S₂O₃)X65 steel
