Title (EN) BOIL-OFF GAS RE-LIQUEFYING METHOD FOR LNG SHIP

Abstract:
(EN) A boil-off gas re-liquefying method for an LNG ship is disclosed. The boil-off gas re-liquefying method for an LNG ship comprises the steps of: (1) compressing a boil-off gas; (2) cooling the boil-off gas, which has been compressed in step (1), by subjecting same to heat exchange by means of a heat exchanger having a boil-off gas as a refrigerant; (3) expanding a fluid which has been cooled in step (2); and (4) stably maintaining re-liquefaction performance even if the flow rate of the boil-off gas to be re-liquefied being supplied to the heat exchanger after being compressed in step (1) varies.
(FR) L'invention concerne un procédé de reliquéfaction de gaz d'évaporation pour un navire transportant du GNL. Le procédé de reliquéfaction de gaz d'évaporation pour un navire transportant du GNL comprend les étapes consistant à : (1) comprimer un gaz d'évaporation; (2) refroidir le gaz d'évaporation, qui a été comprimé à l'étape (1), en le soumettant à un échange de chaleur au moyen d'un échangeur de chaleur ayant un gaz d'évaporation en tant que réfrigérant; (3) détendre un fluide qui a été refroidi à l'étape (2); et (4) maintenir stables des performances de reliquéfaction même si le débit du gaz d'évaporation à reliquéfier qui est fourni à l'échangeur de chaleur après avoir été comprimé à l'étape (1) varie.
(KO) LNG 선의 증발가스 재액화 방법이 개시된다. 상기 LNG 선의 증발가스 재액화 방법은, 1) 증발가스를 압축시키는 단계; 2) 증발가스를 냉매로 상기 1)단계에서 압축된 증발가스를 열교환기에 의해 열교환시켜 냉각시키는 단계; 3) 상기 2)단계에서 냉각된 유체를 팽창시키는 단계; 및 4) 상기 1)단계에서 압축된 후 상기 열교환기로 공급되는 재액화 대상 증발가스의 유량이 변동되어도 재액화 성능을 안정적으로 유지하는 단계;를 포함한다.
