Title:
BOIL-OFF GAS RELIQUEFACTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/043184
Kind Code:
A1
Abstract:
The present invention is provided with: a first heat exchanger EX9 for cooling a boil-off gas BOG flowing through a bleed channel L2 by performing heat exchange with a boil-off gas BOG flowing from a storage tank 10 to a boil-off gas compressor 20; a second heat exchanger EX10 for cooling, in the bleed channel L2, the boil-off gas BOG which has passed through the first heat exchanger EX9 by using a refrigerant N2 flowing through a refrigeration cycle circuit C; and a pressure-setting means 60a for setting the bleed pressure of the boil-off gas BOG bled to the bleed channel L2 to a pressure that is less than the engine supply pressure but is equal to or greater than the liquefaction pressure at which the boil-off gas BOG flowing through the bleed channel L2 is liquefied in the first heat exchanger EX9.
