中文摘要：
环氧乙烷装置中固定床反应器飞温事故频发，造成装置停工，损失严重。利用危险与可操作性分析方法（HAZOP）分析并建立环氧乙烷装置工艺技术安全管理系统是提高装置安全性和可操作性水平的有效途径。讨论了HAZOP分析建兢石化装置工艺技术安全管理系统需要注意的问题，包括原因与后果对应和危险路径模式表达；利用HAZOP分析环氧化反应固定床反应器，建立了固定床反应器的反应模型，验证HAZOP分析结果，并结合工艺安全技术资料分类，给出了环氧乙烷装置工艺技术安全管理系统的构建方法。当装置出现异常工况后．操作员可以利用此系统快速定位和查阅应急处理异常工况时需要的技术资料，以避免事故发生或降低事故后果影响程度。
英文摘要：
The paper intends to introduce an improved safety technol- ogy management system for ethylene oxide device processing devel- oped by the author. As is known, high-temperature runaway acci- dents, which are likely to lead to shutdown of petrochemical devices and even more serious accidents. Such is often the case in the pro- duction process of the fixed bed reactor with the ethylene oxide de-vice. To solve the problem, we have done experiments and adopted the hazard and operability analysis （HAZOP） for analyzing the whole production process of the devices, and then worked out a safety man- agement system for their safety production. In preparing our system, we have discussed and analyzed the following problems： （1） corre- sponding conditions of deviation, cause and effect, etc. ; （2） the ex- pression mode of the hazard-occurring likeliness. Through the HAZOP analysis of the epoxidation reaction process, we have established the epoxidation reaction model of the fixed bed reactor, as a result, con- forming that it is possible for us to use the experimental results to ver- ify and explain the HAZOP reaction consequences. Combining the process safety technology resources of the production device with the HAZOP analysis results, we have time again examined the safety management system of the process technology for ethylene oxide de- vice, in which the key link is to ascertain the influential relationships between the dangerous paths identified by HAZOP analysis and the processing of the safety technology resource files, which should prop- erly be matched with the HAZOP analysis results. In case any abnor- mality occurs, the operator should be able to quickly find out the lo- cations of the necessary flies and keep them in the program database so as to find the errors for the abnormal situation and make it right. Successful application of our safety management system can help greatly to increase the safety of device operation, human safety and operational ability of the petrochemical industry in a variety
