| 摘 要： | 对失效的重油加氢装置脱硫系统再生塔顶空冷器出口 管束进行了外观检查，分别用X射线衍射技术和SEM分析了管束腐蚀产物的相组成、元素含量 与形貌.结果表明，腐蚀减薄穿孔原因是由高温下乙醇胺引起的碱腐蚀所致，硫化氢腐蚀也 起到了辅助作用.

| Abstract: | The appearance of a failed carbon steel tube on heavy oil hydrogenation equipment was examined by naked eye,and the phase composition,element content and microstructure of the corrosion product on the failed carbon steel were analyzed by x-ray spectrum and SEM,respectively.The results indicated that the pitting of the carbon steel was induced by C 2H 7NO mainly and H 2S subordinately. |
