Research on Power Generation Performance of Expander Gas Pressure Regulation

A kind of expander pressure regulating power generation system is proposed,which can recover pressure energy to generate electricity while regulate gas pressure to meet the power demand of pressure regulating facilities.The thermodynamic model of the system is established to study the power generation performance of the system.The research results show that under the condition of absolute inlet pressure of 0.6 MPa and absolute exhaust pressure of0.1 MPa,the average daily power recovery rate of the system is 25.1%,and the daily net power generation is 60.9 kW·h.The system can effectively solve the problem of power consumption of non-electric gas pressure regulating facilities and produce better env ironmental benefits.
