Zusammenfassung: | PURPOSE:To retrieve remaining gas in the tank of the tank-lorry effectively by a method wherein the discharging port of the tank for the tank-lorry, which finished the supply of liquefied gas into a reserving tank, is connected to a low pressure gas holder to transfer and retrieve the remaining gas in the tank into a low pressure gas holder. CONSTITUTION:After the inflow of liquefied gas from the tank-lorry to a reserving tank is finished and the pressures of the both are balanced, the tank of the tank-lorry is connected to the low pressure gas holder installed near the tank- lorry and the remaining gas is retrieved under utilizing the internal pressure of the tank for the tank-lorry. The pressure in the low pressure gas holder is about 0.03kg/cm , therefore, a considerable amount of gas may be retrieved even though a remaining gas pressure in the tank of the tank-lorry is 3kg/cm . |
