Title:
FUEL GAS SUPPLY SYSTEM, VESSEL, AND FUEL GAS SUPPLY METHOD
Document Type and Number:
Japanese Patent JP2019055732
Kind Code:
A
Abstract:
To stably supply boil-off gas to an engine even when supplying the boil-off gas by compression to an engine including use conditions such as having composition ratio of the boil-off gas varied by use of a liquefier for the boil-off gas.SOLUTION: A fuel gas supply system for supplying fuel gas to an engine comprises: a tank for retaining liquefied gas; a pressurizing mechanism for compressing and feeding out the boil-off gas vaporized from the liquefied gas for supplying the same to the engine; and a liquefier for liquefying one portion of the fed out boil-off gas and recovering the same to the tank. The liquefier includes: a liquid recovery control valve for controlling the amount of the liquefied gas flowing through a liquid recovery piping for recovering the liquefied gas liquefied by the liquifier to the tank; and a gas-liquid recovery control valve for controlling the amount of the gas-liquid mixed fluid flowing through a gas-liquid recovery piping for returning the gas-liquid mixed fluid generated by liquefying of the boil-off gas into a liquid phase of the liquefied gas in the tank.SELECTED DRAWING: Figure 1
