摘要: 目前国内危险与可操作性分析(HAZOP)的分析对象多为完整的工艺流程,文章采用HAZOP 分析方法对某重整混合进料换热器改型项目进行了详细的工艺安全和可操作性分析。结合装置改造实际,本次设计变更从原有生产工艺流程、设备制造、施工等方面进行了风险与可操作性识别,并对危险性较大的分析项提出了意见和建议。由于该项目在改造中不改变原有重整装置的生产方法和技术路线,因此本次HAZOP 分析在节点划分与分析思路方面进行了一定的探索,可为类似技术改造项目的HAZOP 分析工作提供借鉴。

Abstract: The analysis object of hazard and operability analysis (HAZOP) in China is mostly complete process flow. This paper adopts HAZOP analysis method to analyze the process safety and operability of a retrofitting project of feed/discharge heat exchanger for reforming reaction in detail. Combining with the actual revamping of the plant, this design change has identified the risk and operability from such aspects as the original production process, equipment manufacturing, construction, and so forth and puts forward opinions and suggestions on the more dangerous analysis items. Since the project does not change the production method and technical route of the original reformer during the revamp, this HAZOP analysis has carried out certain exploration in node division and analysis ideas, which can provide reference for HAZOP analysis work of similar technological revamp projects.

Key words: hazard and operability study/HAZOP, reforming reaction, heat exchanger modification, deviation
