摘要
原料油常压储罐是大型石化装置中重要的物料储存设备,储罐的结构健康完整性与全装置的稳定运行息息相关。对大型常压储罐进行定期的检验检测有利于保障其本质安全,随着大型常压储罐的长周期使用,腐蚀问题是造成常压储罐出现泄漏的一大隐患。以珠三角地区的某台5000 m^(3)的原料油常压储罐为研究案例,在全面检验过程中发现底板出现了严重腐蚀缺陷,分析了底板腐蚀原因,提出了防范建议,为国内类似的工程应用提供参考案例。
The atmospheric storage tank for raw oil is an important material storage equipment in large petrochemical plants,and the structural health and integrity of the storage tank are closely related to the stable operation of the entire plant.Regular inspection and testing of large atmospheric storage tanks is beneficial for ensuring their intrinsic safety.With the long-term use of large atmospheric storage tanks,corrosion is a major hidden danger that causes leaks in atmospheric storage tanks.Taking a 5000 m^(3) raw material oil atmospheric storage tank in the Pearl River Delta region as a research case,serious corrosion defects were found in the bottom plate during the comprehensive inspection process.The causes of bottom plate corrosion were analyzed,and prevention suggestions were proposed,providing reference cases for similar engineering applications in China.
