摘　　要：老旧装置的继续使用一直是生产安全监管部门、特种设备监管部门和使用单位关注的重点。本文在调查了3套常减压装置的腐蚀情况的基础上,采用《危险化学品生产使用企业老旧装置安全风险评估指南(试行)》中的方法和基于风险的检验方法分别得到了装置的安全风险。通过分析使用时间、介质、材质等因素对安全风险的影响,对比了2种方法的特点和所得到的安全风险等级,发现2种方法得出的安全风险等级是相互对应的,这2种方法可以结合使用。The long-time using of old devices has always been the focus of production safety supervision departments,special equipment supervision departments and users.In this paper,on the basis of corrosion investigation of three atmospheric and vacuum distillation units,the safety risk of the unit is obtained by using the method in the Safety Risk Assessment Guide for Old Units of Hazardous Chemical Production and Use Enterprises(trial)and the risk-based inspection method respectively.By analyzing the influence of factors such as using time,medium,material on security risks,the characteristics and safety risk levels of the two methods are compared,and it is found that the safety risk levels obtained by the two methods are corresponding to each other and the two methods can be used in combination.
