低温甲醇洗装置损伤机理分析和RBI技术的应用

Damage Mechanism Analysis and Application of RBI Technology in Rectisol Unit

采用基于风险的检验(RBI)方法,对某煤化公司低温甲醇洗装置进行了风险评估。根据设备材质、工艺介质和操作工况,分析了装置存在的失效模式和损伤机理;采用风险评估软件对设备失效可能性和失效后果进行计算,确定了设备的风险等级,并分析了装置的风险分布情况和部分设备存在较高风险的原因,为装置检验策略的制定提供了可靠的依据。

Risk based inspection(RBI)method was used to evaluate the risk of rectisol unit in a coal chemical company.According to the materials,process mediums and operating conditions,failure mode and damage mechanism of the equipment were analyzed.Risk assessment software was used to calculate the possibility as well as consequence of the failure,and then risk level of the equipment was determined;moreover,risk distribution of the unit and reasons for some high-risk equipment were analyzed,which provided reference for the formulation of inspection strategy.
