PURPOSE: A liquefied gas storage tank is provided to easily discharge an inert gas from the storage tank by installing a tank structural member with an LPG(Liquefied Petroleum Gas) vapor gas suction pipe. CONSTITUTION: A liquefied gas storage tank(10) comprises an upper plate(20) for a tank and an LPG vapor gas suction pipe(40). The suction end(40') of the LPG gas suction pipe is connected to a tank dome(22) formed on the tank upper plate of the storage tank. When the height of the LPG vapor gas rises, an inert gas is filled in advance and discharged by the LPG through the vapor gas suction pipe. |
