| 摘 要： | 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．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． |
| 关 键 词： | 乙醇胺 缓蚀剂 缓蚀机理 低碳钢 |

| Abstract: | The corrosion behavior and the effect of the corrosion inhibitor on those behavior of carbon steel in MEA solution abounded with H 2S 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 H 2S and IMC-C5 inhibitor has an excellent inhibitive performance mainly from the strong retardation to the anodic process.The corrosion inhibitor is an anodic adsorption type inhibitor. |
| Keywords: | monoethanolamine (MEA) corrosion inhibitor mechanism mild steel |
