Analysis and Research on Airflow Pulsation in Nitrogen Compressor Pipeline System
This paper took the nitrogen compressor as the research object,analyzed the airflow pulsation of the first stage inlet pipeline,and calculated the pressure pulsation spectrum of pulsation nodes such as elbows,reducers,and tees.It was found that the pulsation amplitude of the maximum point of airflow pulsation was 13.9 times that of the guide line in API618 the 5th edition.Based on the analysis results,the cause of the large airflow pulsation was identified,and a method was proposed to increase the diameter of some pipelines while modifying the position of the safety valve outlet.After adjustment,the pulsation amplitude of the maximum point of airflow pulsation decreased to 2.1 times that of the guide line,and the pulsation imbalance force causing vibration was within the guide line,indicating that the adjustment plan was effective.
