摘　　要：本文根据科学测厚部分原理,即某焦化装置工艺过程及装置典型损伤机理,在对比原料成分的基础上,对设备及管线进行腐蚀回路划分。一方面选取装置部分管道定点测厚数据进行RBI分析,计算退役极限;另一方面基于停工检修期间,对部分塔器,容器进行腐蚀检查及科学测厚数据,计算腐蚀速率计算及下次建议检验日期,得出重点腐蚀部位,与相关标准进行对比,分析腐蚀原因,并给出腐蚀防护建议。The division of corrosion circuit on equipment and pipeline for the coking plant based on a coking plant process, typical damage mechanism and raw material composition analysis, which also come from a part of scientific thickness principle. On one hand, we select thickness measurement data of pipeline for the RBI analysis and the calculation of retired limit. On the other hand, we calculate the corrosion rate and recommended nest inspection date based on corrosion inspection and scientific thickness measurement data during the shutdown maintenance period, which includes a part of the tower and container in eoking plant. It is concluded that we give the significant corrosion parts of eoking plant compared with the related standard, analyzes the reasons of corrosion, and give some corrosion protection advice for this coking plant.
