Evaluation of the corrosion resistance of SA-543 and X65 steels in emulsions containing H2S and CO2 using a novel emulsion flow loop

摘要

A novel emulsion flow loop was constructed to investigate the corrosion resistance (R-P) of SA-543 and X65 steels in oil-in-water emulsions containing H2S and CO2. Results show that R-P of SA-543 steel is significantly better than that of X65 steel. The R-P, which increases with increasing oil concentration, velocity, and temperature, is lower in the developing flow region when compared to that in the fully developed region.
