Document Type and Number:
WIPO Patent Application WO/2021/015399
Kind Code:
A1
Abstract:
Disclosed is a fuel gas management system for a ship. A fuel gas management system for a ship according to the present embodiment includes: a storage tank for receiving liquefied gas and boil-off gas generated therefrom; a re-liquefaction line for re-liquefying the boil-off gas and resupplying the same to the storage tank; a refrigerant circulation line providing cold heat through a refrigerant; and a first heat exchanger and a second heat exchanger provided between the re-liquefaction line and the refrigerant circulation line. The re-liquefaction line includes: a first heat exchange unit for re-liquefying heavy hydrocarbons contained in the boil-off gas by performing, in the first heat exchanger, a primary heat exchange and cooling of the boil-off gas discharged from the storage tank; a gas-liquid separator for separating re-liquefied components and non-liquefied components generated as a result of passing through the first heat exchange unit; and a second heat exchange unit for supercooling and re-liquefying the non-liquefied components, separated in the gas-liquid separator, by performing a secondary heat exchange in the second heat exchanger. The re-liquification line can be provided to re-supply the storage tank with boil-off gas that has supercooled and re-liquefied by passing through the second heat exchange unit.
