Application of Natural Gas Compressor Efficiency Monitoring
The purpose of compressor efficiency monitoring for long-distance natural gas pipelines is to monitor the operating status of the compressor in real time,and formulate maintenance plans,so as to achieve the purpose of operating the compressor in the most economical way.According to the theo-ry of thermodynamics,the natural gas compression factor,enthalpy and other physical parameters are calculated using the values of all components of natural gas,the inlet and outlet pressures and tempera-tures of the compressor,and the inlet flow value of the compressor.The total energy consumption out-put of the compressor is calculated using the enthalpy difference,and the real-time performance moni-toring data such as the compressor output power,compressor shaft power,variable efficiency,gas tur-bine efficiency,and gas drive efficiency are calculated using the fuel gas consumption of the compressor and the lower calorific value of the fuel gas.So as to calculate the energy consumption of the entire line compressor during operation,as well as the difference in energy consumption between compressors with the same service life and model.According to the compressor efficiency monitoring data,the op-erating conditions of the compressor can be effectively adjusted,and the maintenance effect of the com-pressor can be evaluated.The optimal energy consumption operation of the compressor unit,and the safe,stable,and efficient operation of the entire pipeline are achieved,which has a certain guiding significance for the efficiency monitoring of compressors of the same type.
