GAS CHARGING SYSTEM WITH A RESIDUAL GAS RECOVERY DEVICE, AND A RESIDUAL GAS RECOVERY METHOD

摘要

PURPOSE: A gas charging system with a residual gas recovery device, and a residual gas recovery method are provided to reduce distribution costs and optimize charging efficiency by controlling residue gas remaining in a tube trailer.;CONSTITUTION: A gas charging system with a residual gas recovery device comprises a feeding tank(130), an oil tank(140), an oil guide tube(170), an oil collection pipe(180), a pressure sensor(133) and an oil position detecting sensor. The feeding tank is connected to the feeding tank branched from a gas service pipe. The oil for the residue gas compression stores in the oil tank. The oil guide tube is connected between the oil tank and the feeding tank. The oil collection pipe is connected between the feeding tank and the oil tank. The pressure sensor measures the pressure of residue gas charged in the feeding tank. The oil position detecting sensor measures the amount of oil of the feeding tank.;COPYRIGHT KIPO 2011
