PURPOSE:To rduce the amount of the liquefied gas to be processed outside a tank by directly contacting and mixing a portion of the evaporated gas generated during the acceptance into the tank with the low temperature liquefied gas accepted so as to re-liquefy it by means of coldness. CONSTITUTION:An ejector 3 is provided in the evaporated gas layer 5 at the upper section in the acceptance tank 1 of the low temperature liquefied gas and a gas suction quantity regulator 4 is fitted to the ejector 3, and the regulator 4 is constituted so that it can be controlled from outside the tank, then the tip 2' of an acceptance pipe 2 is connected to the ejector 3. When the low temperature gas is fed through the acceptance pipe 2, the evaporated gas is sucked into the ejector 3 from the gas layer 5, and the low temperature liquefied gas and the evaporated gas get into a direct contact and are mixed with each other in a mixing pipe 6, thereby the evaporated gas is re-liquefied by means of coldness of the low temperature liquefied gas. |
