Title: Thermodynamic Analysis on Recovery of Pressure Energy at the City Gas Gate Station
Abstract: The gas from long-distance pipeline should be regulated to lower pressure before it enters the city gas distribution system.This throttling process causes a loss of pressure energy.In this paper,the exergy analysis method was adopted to carry out thermodynamic analysis of the pressure regulation at the city gas gate station.The result shows that reducing pressure by throttle valve can meet the technological requirements,but exergy loss is great and exergy efficiency is low in throttling process.So it is necessary to consider other equipments for pressure energy recovery to replace throttle valve in order to recovery the pressure energy lost in pressure regulation process.The equipments include turbo expander,turbine and so on.
