摘要/Abstract

摘要： 乙烯裂解炉辐射炉管在苛刻工作环境下长期工作时，其失效机理涉及炉管渗碳、鼓包变形、裂纹断裂等；在气相原料的裂解炉中，炉管的鼓胀现象较为明显。随着炉管鼓胀的发生，炉管产生穿透性裂纹的风险提升，可能导致装置紧急停产。为有效降低此类风险，某石化公司在裂解炉维护期间，采用智能检测系统对炉管进行全面爬行检测，首次获取了行业内乙烯裂解服役炉管全域的鼓胀数据等外观信息。通过对炉管鼓胀与渗碳数据进行交叉分析，进一步验证了炉管的变形鼓胀与材料渗碳的紧密关联。此外，上述检测数据还可用于优化生产工艺参数、制定基于数据的炉管维护和更换计划，为提高生产效率和降低停产风险提供数据支持。

Abstract: When the radiant furnace tubes of the ethylene cracking furnace operate for a long time under severe working conditions, the failure mechanism involves tube carburization, bulging deformation, crack fracture, etc.; the bulging phenomenon of the tubes is more obvious in cracking furnaces with gasphase feedstock.With the occurrence of furnace tube bulging, the risk of penetrating cracks in the furnace tube is elevated, which could lead to emergency shutdown of the unit. In order to effectively mitigate such risks, one petrochemical company employed an intelligent inspection system to carry out comprehensive crawling inspections on furnace tubes during cracker maintenance and for the first time obtained the surface information such as bulging data for the entire domain of the furnace tubes in service for ethylene cracking in the industry.Through a crossanalysis of furnace tube bulging and carburization data, the close correlation between bulging and carburization is further validated. In addition, the above inspection data can be utilized to optimize production process parameters and prepare datadriven plans for furnace maintenance and tube replacement, providing data support for enhancing production efficiency and reducing shutdown risks.
