解决炼油化工装置腐蚀问题的方法研究

RESEARCH ON METHODS TO SOLVE CORROSION PROBLEMS IN REFINING AND CHEMICAL UNITS

炼化装置,即使是催化裂化等非常成熟的常规装置,历经几十年的发展,腐蚀问题仍然普遍存在。其主要问题是缺少全面、系统的解决腐蚀问题的方法。文章通过对大量的标准规范、腐蚀机理、工程设计经验进行总结,并分析了上百套装置现场腐蚀的问题,发现解决装置腐蚀问题需要两个层面:1)空间维度,将工程设计和应用的工艺、设备等的专业防腐工作融为一体,形成装置整体防腐工作方法;2)时间维度,将行业层面积累的经验和教训进行结构化、系统化的整合,为工程技术人员提供技术支持和服务,快速提升其分析和解决腐蚀问题的能力。

Corrosion problems are still prevalent in refining units,even in very mature conventional units such as catalytic cracking units after decades of development.The main problem is the lack of comprehensive and systematic methods to solve corrosion problems.Through summarizing a large number of standard specifications,corrosion mechanisms,engineering design experience,and analyzing the corrosion problems of hundreds of device on sites,this paper found that two levels of solutions to device corrosion problems were required:1)from the spatial dimension,integrating professional corrosion prevention work such as engineering design and application processes and equipment to form an overall corrosion prevention work method for the device;2)from the time dimension,the experience and lessons accumulated and drawn from the industry are structured and systematically integrated to provide technical support and services for engineers and technicians to improve their ability to analyze and solve corrosion problemsquickly.
