Comparative Analysis and Prediction of the Effect of Gas Parameters on the Efficiency of Gas-driven Compressor

In order to optimize the performance of gas-driven compressor units and improve energy efficiency,using the efficiency model combined with the actual operating parameters of the gas reciprocating compressor unit of a domestic natural gas storage,taking the gas parameters as variables to obtain the partial derivative of the efficiency formula,the influence degrees of the ef-ficiency of the reciprocating compressor unit in the actual operation were quantitatively analyzed. By analyzing the influence of inlet and outlet pressure and inlet and outlet temperature on the working efficiency,combined with the analysis of the key components of the compressor,the fea-sibility of parameter adjustment to improve the performance of the compressor is demonstrated, and thus the theoretical reference of the optimization of gas-driven compressor performance is provided.
