SYSTEM FOR KEEPING HIGH-PRESSURE OF STORAGE CONTAINER FOR PRESSURIZED LIQUEFIED NATURAL GAS

摘要

PURPOSE: A system for maintaining the high pressure of a compressed LNG storage tank is provided to secure the stabilization of an unloading work by preventing the blockage of a nozzle and a pipe. CONSTITUTION: A system for maintaining the high pressure of a compressed LNG storage tank comprises an unloading line(410) and a pressure supplementary line(420). The unloading line is connected from the storage tank to a storage tank of a consumption site to unload compressed LNG. The pressure supplementary line is branched from the unloading line and supplies the compressed LNG to the storage tank by vaporizing some of the compressed LNG with a vaporizer.
