PURPOSE: A high pressure maintaining system for a pressurized LNG storage tank is provided to stably load and unload by preventing freeze of carbon dioxide due to decreased pressure and temperature while loading and unloading pressurized LNG gas. CONSTITUTION: A high pressure maintaining system for a pressurized LNG storage tank comprises a loading/unloading line(410), a pressure supplementary line(420), and an evaporator(430). The loading/unloading line is connected to a storage tank of a demanding location from a storage container to enable to load and unload pressurized liquefied natural gas. The pressure supplementary line is branched from the loading/unloading line and is connected to the storage container. The evaporator is installed in the pressure supplementary line and evaporates the pressurized liquefied natural gas. |
