９号公輻に開示されている。There are two ways to ship low-temperature liquefied gas in storage tank equipment: one is to heat it with a heating device and ship it as a liquid close to room temperature, and the other is to evaporate it with a vaporizer and ship it as a gas close to room temperature. In JP-A-59-1836, the cold energy generated in the former case is stored and used for the cold energy required when re-liquefying the gas generated in the low-temperature liquefied gas storage tank.
It is disclosed in Publication No. 9.
