利用失重、腐蚀电化学方法和表面分析技术研究了碳钢在富含H2S的乙醇胺（MEA）溶液中的腐蚀行为，以及添加缓蚀剂后对其电化学行为的影响。讲座讨论了IMC-C5缓蚀剂对该体系的缓蚀作用机理。结果表明，脱硫系统中吸收了硫化氢的乙醇胺溶液对碳钢的腐蚀十分严重，IMC-C5缓蚀剂能有效控制碳钢在该体系中的腐蚀，其缓蚀作用主要来自于吸附缓蚀剂分子对腐蚀阳极过程的抑制，为阳极吸附型缓蚀剂。
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.
