Abstract Naphthenic acid corrosion (NAC), sulfur corrosion (SC) and their interaction on Cr5Mo carbon steel were studied by mass loss test using a spinning coupon inside a heated autoclave at 280℃. The test mixture with different level of sulfur content and total acid number were prepared by pure naphthenic acid, lauryl mercaptan and low sulfur white oil. It was found that the increasing sulfur content can accelerate the NAC dramatically when the sulfur content lower than 2.0 mass%. However, the boost effect of mercaptan to NAC decreased quickly when the sulfur content is higher than 3.0 mass{\%}, which could be attributed to the formation of protective Fe₇S₈/Cr₅S₈ layer confirmed by scanning electron microscope（SEM）, energy dispersive X-ray（EDX） analysis and X-ray diffraction（XRD） analysis. Surprisingly, high content of lauryl mercaptan could even inhibit the NAC in case of higher TAN (>15.0 mg/g KOH), and the increasing content of TAN could enhance the inhibition of mercaptan on NAC. In contrast, the dimethyl sulfoxide（DMSO）exhibits stronger inhibition ability than mercaptan in case of high TAN in the test mixture.
