介绍了腐蚀在线监测技术及其在蒸馏装置塔顶空冷器上的应用 ,探讨了蒸馏装置炼制超稠油时低温部位的腐蚀规律 ,指出腐蚀监测结果基本符合实际情况 ,其塔顶低温部位腐蚀速率大于 0 .1mm/a ,应加强工艺注剂的优化。腐蚀深度测试灵敏度为 0 .1μm。
This paper introduced the on-line corrosion monitoring technology and its application on the top air cooler of the distillation unit. The corrosion mechanism of the low-temperature part of the distillation unit when it was used to refine super heavy oil was discussed. The corrosion monitoring results were basically in line with the actual conditions. Rate greater than 0 .1mm / a, should strengthen the process of injection optimization. Corrosion depth test sensitivity of 0.1μm.
