Abstract:
(EN) A boil-off gas re-liquefying system for an LNG ship is disclosed. The boil-off gas re-liquefying system for an LNG ship comprises: a heat exchanger for heat exchanging a high-temperature fluid, which is a boil-off gas compressed by means of a compressor, with a low-temperature fluid, which is a boil-off gas before compression, and cooling same; and an expansion means for expanding a fluid which has been cooled by means of the heat exchanger. The heat exchanger comprises: a core having a plurality of blocks in which the heat exchange between the high-temperature fluid and the low-temperature fluid occurs; and a fluid dispersing means for dispersing a fluid which flows into the core and a fluid which is discharged from the core. The core comprises a plurality of blocks. The fluid dispersing means is coupled to the heat exchanger so as to enable heat expansion relief.
(FR) Système de reliquéfaction de gaz d'évaporation pour un navire de GNL. Le système de reliquéfaction de gaz d'évaporation pour un navire de GNL comprend : un échangeur de chaleur pour effectuer un échange de chaleur entre un fluide à haute température, qui est un gaz d'évaporation comprimé au moyen d'un compresseur, et un fluide à basse température, qui est un gaz d'évaporation avant compression, et refroidir celui-ci ; et un moyen d'expansion pour dilater un fluide qui a été refroidi au moyen de l'échangeur de chaleur. L'échangeur de chaleur comprend : un noyau ayant une pluralité de blocs dans lesquels se produit l'échange de chaleur entre le fluide à haute température et le fluide à basse température ; et un moyen de dispersion de fluide pour disperser un fluide qui s'écoule dans le noyau et un fluide qui est évacué du noyau. Le noyau comprend une pluralité de blocs. Le moyen de dispersion de fluide est accouplé à l'échangeur de chaleur de façon à permettre une libération de la dilatation thermique.
(KO) LNG 선의 증발가스 재액화 시스템이 개시된다. 상기 LNG 선의 증발가스 재액화 시스템은, 압축기에 의해 압축된 증발가스인 고온유체를 압축 전 증발가스인 저온유체와 열교환시켜 냉각시키는 열교환기; 및 상기 열교환기에 의해 냉각된 유체를 팽창시키는 팽창수단;을 포함하고, 상기 열교환기는, 상기 고온유체와 상기 저온유체의 열교환이 발생하는 다수개의 블럭을 포함하는 코어; 및 상기 코어로 유입되는 유체 또는 상기 코어로부터 배출되는 유체를 분산시키는 유체 분산 수단;을 포함하고, 상기 코어는 다수개의 블럭을 포함하며, 상기 유체 분산 수단은 열신축 해소가 가능하도록 상기 열교환기와 결합된다.
