Title:
LIQUEFIED GAS FUEL SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/149860
Kind Code:
A1
Abstract:
Disclosed is a system for supplying liquefied gas fuel to a ship, a land transportation means, or a plant by using, as fuel, liquefied gas such as natural gas, natural petroleum gas, hydrogen, and ammonia. A liquefied gas fuel supply system according to the present embodiment comprises: a liquefied gas storage tank module for accommodating liquefied gas and boil-off gas generated therefrom; a fuel supply module for supplying the liquefied gas as fuel; and a boil-off gas treatment module in which a portion of the boil-off gas is re-liquefied so as to be collected in a storage tank, and in which a portion is supplied to a gas-requiring place. The boil-off gas treatment module has an ejector for treating the boil-off gas of the storage tank so that the motive side thereof uses supercooled liquefied gas having passed through a boosting pump path, and the suction part thereof is formed as a boil-off gas supply line of the storage tank. The liquefied gas fuel supply system allows a fluid having passed through the ejector to form a gas-liquid mixed fluid as the supercooled liquefied gas supplied to the motive side and the low-temperature boil-off gas are mixed, has a gas-liquid separator for separating the fluid into a gaseous state and a liquid state, so that the liquid liquefied gas is collected in the storage tank and the gaseous gas is supplied to a generator engine, and receives fuel gas from the fuel supply module to meet a fuel supply amount required by the generator engine.
