连续重整循环氢压缩机振动原因分析及对策

Cause Analysis and Countermeasures for Viberation of Recycle HydrogenCompressor in Circulating Reforming Unit

某石化公司连续重整装置循环氢压缩机出现振动值增大的问题,对装置的平稳生产造成影响。通过频谱分析判断振动的主要原因为转子不平衡,根据工艺运行状况及对垢样成分检测的结果,得出压缩机转子存在氯化铵盐结垢的结论并得以验证,提出应对策略并实施,保证了机组的长周期运行。

Regarding the problem at high viberation of recycle hydrogen compressor in circulating reforming unit of a petrochemical company it had affected the stable production.The main reason of vibration is rotor unbalance by spectral analysis.According to the operation status of the device and the detection results of the scale sample composition,it is concluded that the compressor rotor has ammonium salt,which has been verified.The countermeasures are pointed out in the paper and are implemented,which has ensured the long period stable operation of compressor.
