Abstract: front page image
(EN) Disclosed is a ship having a liquefied gas storage tank. The ship comprises: a multi-stage compressor for compressing a boil-off gas discharged from a storage tank and comprising a plurality of compression cylinders; a second heat exchanger for heat exchanging a fluid, which has been compressed by means of the multi-stage compressor, and thus cooling same; a first decompressing device for expanding a flow (hereafter referred to as "flow a1") partially branched from the flow (hereafter referred to as "flow a") that has been cooled by means of the second heat exchanger; a third heat exchanger for heat exchanging, by means of "flow a1" which has been expanded by means of the first decompressing device as a refrigerant, the remaining flow (hereafter referred to as "flow a2") of "flow a" after excluding "flow a1" that has been branched and thus cooling same; and a second decompressing device for expanding "flow a2" which has been cooled by means of the third heat exchanger, wherein the second heat exchanger cools the fluid, which has been compressed by means of the multi-stage compressor, by means of "flow a2", as a refrigerant, which has been expanded by means of the second decompressing device.
(FR) La présente invention concerne un navire comportant un réservoir de stockage de gaz liquéfié. Le navire comporte: un compresseur à étages multiples pour comprimer un gaz d'évaporation évacué à partir d'un réservoir de stockage et comprenant une pluralité de cylindres de compression; un deuxième échangeur de chaleur pour l'échange de chaleur d'un fluide, qui a été comprimé au moyen du compresseur à étages multiples, et donc son refroidissement; un premier dispositif de décompression pour la détente d'un flux (désigné ci-après "flux a1") partiellement ramifié à partir du flux (désigné ci-après "flux a") qui a été refroidi au moyen du deuxième échangeur de chaleur; un troisième échangeur de chaleur pour l'échange de chaleur, au moyen du "flux a1" qui a été détendu au moyen du premier dispositif de décompression sous forme d'un réfrigérant, du flux restant (désigné ci-après "flux a2") du "flux a" après l'exclusion du "flux a1" qui a été ramifié et donc son refroidissement; et un second dispositif de décompression pour la détente d'un "flux a2" qui a été refroidi au moyen du troisième échangeur de chaleur, le deuxième échangeur de chaleur refroidissant le fluide, qui a été comprimé au moyen du compresseur à étages multiples, au moyen du " flux a2 ", sous forme d'un réfrigérant, qui a été détendu au moyen du second dispositif de décompression.
(KO) 액화가스 저장탱크가 탑재된 선박이 개시된다. 상기 선박은, 상기 저장탱크로부터 배출된 증발가스를 압축시키며, 다수개의 압축실린더를 포함하는 다단압축기; 상기 다단압축기에 의해 압축된 유체를 열교환시켜 냉각시키는 제2 열교환기; 상기 제2 열교환기에 의해 냉각된 유체(이하, 'a 흐름'이라고 함.)가 일부 분기된 흐름(이하, 'a1 흐름'이라고 함.)을 팽창시키는 제1 감압장치; 상기 제1 감압장치에 의해 팽창된 상기 'a1 흐름'을 냉매로, 상기 'a 흐름' 중 분기된 'a1 흐름'을 제외한 나머지 유체(이하, 'a2 흐름'이라고 함.)를 열교환시켜 냉각시키는 제3 열교환기; 및 상기 제3 열교환기에 의해 냉각된 상기 'a2 흐름'을 팽창시키는 제2 감압장치;를 포함하고, 상기 제2 열교환기는, 상기 제2 감압장치에 의해 팽창된 상기 'a2 흐름'을 냉매로 하여, 상기 다단압축기에 의해 압축된 유체를 냉각시킨다.
