PURPOSE:To hold the space in a liquefied gas tank at a predetermined pressure by spraying liquefied gas into a liquefied gas tank through a spray nozzle so as to condense the gas in the liquefied gas tank. CONSTITUTION:When liquefied gas is received into a liquefied gas tank 2, the liquefied gas is fed by a pump to the liquefied gas tank 2 side from a liquefied gas storage tank through a pipeline 3 and is sprayed into the liquefied gas tank 2 through a spray nozzle 4. Part of the gas gathered in the liquefied gas tank 2 is condensed, re-liquefied, and returned to the liquid surface, thereby the space in the liquefied gas tank 2 is held approximately at a predetermined pressure. Accordingly, no special line is required to be provided for the gas return. |
