Corrosion Behavior of 110SS Steel in Self‐Generated Acid at High Temperature
ABSTRACT The corrosion behavior of hydrogen sulfide corrosion‐resistant alloy steel 110SS in the self‐generated acid system at (ultra‐) high temperature was studied. The results of the weight loss experiment showed that the corrosion rate of 110SS steel decreased with the increase of temperature at 120°C–200°C. The comprehensive study of SEM‐EDS and XPS showed that FeCO 3 was formed on the surface of 110SS steel. With the increase in temperature, FeCO 3 became dense, and the corrosion rate of self‐generated acid decreased. In addition, when the temperature is 120°C, the results of weight loss experiment and 3D laser scanning show that the corrosion of 110SS steel is strong, and the corrosion phenomenon is inhibited after adding oleic imidazoline. SEM and electrochemical experiments show that the oleic imidazoline corrosion inhibitor can be stably adsorbed on the surface of 110SS steel and reduce its corrosion in the self‐generated acid.
