The main objective was to study if the high concentration of chloride could initiate localized attack in this type of H2S system. Experiments were conducted in a nitrogen-purged system with a trace amount of H2S (50 ppm) in the gas phase. Only weight loss was used to measure corrosion rates. Scanning electron microscopy (SEM) and energy-dispersive x-ray (EDX) methods were used to characterize the corrosion products. Experimental results show that a high salt concentration significantly slowed down the reaction rate in H2S corrosion. Some pitting attack was found both in salt-free and high salt conditions, but experimental results did not show evidence that chlorides can initiate localized corrosion in low pH2S systems.
