随着加工原油的多样化和劣质化日趋严重,炼油装置的腐蚀问题越来越突出。设备与管道的腐蚀问题已成为制约炼化装置长周期运行的瓶颈,而专业化腐蚀检查则是炼化行业有效应对装置腐蚀的可行方法。通过公司装置停产大检修期间进行专业化腐蚀检查的尝试,在分析总结专业化防腐检查的基础上,得出重点装置设备与管道的腐蚀原因与防腐措施,及时消除装置的腐蚀隐患。建议公司将装置检修与专业化腐蚀检查有机结合并形成制度,为炼化装置的设备与管道防腐提供有力的技术支撑,保障装置的“安稳长满优”运行。
With the diversification and inferior quality of processed crude oil becoming more and more serious, the problem of corrosion of the refinery is becoming more and more prominent. Corrosion of equipment and pipelines has become a bottleneck restricting the long-term operation of refinery plant, and specialized corrosion inspection is a feasible way for the refining industry to effectively deal with the corrosion of the plant. Attempt to carry out specialized corrosion inspection during the overhaul and major overhaul of the company’s installations. Based on the analysis and conclusion of the specialized anti-corrosion inspection, the causes of the corrosion of the key equipment, equipment and pipes and the anticorrosion measures are obtained, and the potential corrosion problems of the equipment are promptly eliminated. It is suggested that the company organically combine the equipment maintenance and specialized corrosion inspection and form a system to provide strong technical support for the equipment and pipeline anticorrosion of the refining plant and ensure the operation of the plant.
