Abstract The corrosion behavior and the effect of the corrosion inhibitor on those behavor of carbon steel in MEA solution abounded with H2S was investigated by static weight loss test, electrochemical method and surface analytical techniques.The inhibitive mechanisms of IMC-C5 inhibitor under the circumstance were discussed.The results show that mild steel was severely damaged in MEA solution abounded with H2S and IMC-C5 inhibitor has an excellent inhibitive performance mainl from the strong retardation to the anodic process.The corrosion inhibitor is an anodic adsorption type inhibitor.

Key words: monoethanolamine(MEA) corrosion inhibitor mechanism mild steel
