吸附塔声发射定期在线检测方法的研究与应用

Research and Application of the Periodical On-Line Inspection Method of Acoustic Emission of Adsorption Towers

以某炼油厂40000m3/h(N)PSA制氢装置中10台吸附塔为对象,进行了气压试验过程的声发射检测和投产运行3年后的声发射在线检测。通过对检测数据进行对比分析,10台吸附塔安全状况良好,可继续使用。

Based on the ten adsorption towers in the 40 000m^3/h（N）PSA synthetic ammonia equipment of a refinery, the acoustic emission inspections in the processes of atmospheric pressure tests and the acoustic emission on-line inspections after operation of three years were performed. The comparative analyses of the inspection data show that the safe status of the ten towers is good, and they can be continuously used.
