摘要
常减压蒸馏装置受原油高硫高酸化的影响,腐蚀情况日益严重,对安全生产构成威胁。针对其内部特殊的腐蚀环境,结合工程实际案例总结了主要的腐蚀影响因素,重点介绍了常顶部位和减压塔底泵的腐蚀与防护措施,并对腐蚀在线监测技术进行了阐述,对现阶段常减压蒸馏装置防腐蚀工作的发展趋势进行了展望。
The atmospheric ＆ vacuum distillation unit suffered from increasingly serious corrosion under the impact of high sulfur and high acid in crude oil, which threatened the safe operation of the unit. In view of the special interual corrosion environment and through a case study, the main impact factors of corrosion were summarized and the corrosions of atmospheric tower overhead and vacuum tower bottom pumps and protection measures were introduced. The on - line corrosion monitoring technology was described. The development trend of corrosion protection of atmospheric ＆ vacuum distillation unit both in China and abroad was discussed.
