Abstract: The isentropic boosting technology is adopted to develop a pressure energy recovery device, which can transfer the excess pressure energy of the high-pressure gas source to the low-pressure gas for pressurization so that the high and low pressure gas sources can simultaneously meet the pressure of the gas pipeline network for exporting. There is almost no conversion of mechanical energy and internal energy of gas in the operation process, which is close to the isentropic process and the use of the pressure energy of high-pressure gas is maximized.
