Excessive vibration was observed from hydrogen reciprocating compressor pipelines since the capacity expansion revamping of this unit finished in a refinery. The production had been frequently stopped since the vibrations on the pipelines exceeded the alarm value, which often led to a delivery failure of Hydrogen for subsequent reactions, causing great economic losses. In order to identify the root cause of vibration, reduce the airflow pulse peak, and enhance the pipeline security strength and rigidity of the structure, a comprehensive analysis on the reciprocating compressor and pipeline system was conducted. The vibration has been constrained in an acceptable range after the adjustment, and the unit has gotten a long-period and stable operation.
