liquefied natural gas storage and carriers and surplus gas generation suppression method of liquefied natural gas storage and carriers

摘要

PROBLEM TO BE SOLVED: To provide a liquefied natural gas storage/transport ship that reduces the amount of natural gas generated when liquefied natural gas (LNG) is loaded into a liquefied natural gas ship on-board storage tank and which minimizes the amount of excess gas generated due to LNG loading.;SOLUTION: The liquefied natural gas storage/transport ship is provided with a liquefied natural gas ship on-board storage tank 2 which stores the liquefied natural gas in an supercooled state, wherein a top liquefied natural gas introduction system 20 is provided to allow loading of the liquefied natural gas to be loaded by introduction into the tank from near the top of the tank, and also, when the liquefied natural gas is loaded into the liquefied natural gas ship on-board storage tank 2, the tank pressure is raised, increasing the boiling point so that the loaded liquefied natural gas assumes a supercooled state.;COPYRIGHT: (C)2012,JPO&INPIT
