Title:
METHOD FOR DISCHARGING LIQUID REMAINING IN LIQUEFIED GAS TANK
Document Type and Number:
WIPO Patent Application WO/2015/159790
Kind Code:
A1
Abstract:
In the present invention, water is injected into a liquefied gas tank (1) from the upper part of the tank (water injection step); accumulated liquid remaining in the liquefied gas tank (1) is gasified by the heat of the water injected in the water injection step, and is discharged from the upper part of the liquefied gas tank (1) (remaining liquid gasification/discharge step); water continues to be injected into the liquefied gas tank (1) even after all of the accumulated liquid is gasified in the remaining liquid gasification/discharge step, and the temperature inside the liquefied gas tank (1) is returned to normal temperature while the ice (which is formed when the water solidifies due to the cold heat appropriated from the accumulated liquid in the remaining liquid gasification/discharge step) melts (heat-up step); and inert gas is supplied to the interior of the liquefied gas tank (1) while water is discharged from the bottom of the liquefied gas tank (1), the interior of which has been returned to normal temperature in the heat-up step (water discharge step).
