Abstract: front page image
(EN)Disclosed is a re-liquefying device using a boil-off gas as a cooling fluid so as to re-liquefy the boil-off gas generated from a liquefied gas storage tank provided in a ship. A boil-off gas re-liquefying device for a ship comprises: a plurality of compressors for compressing, in multiple stages, a boil-off gas discharged from a storage tank; a heat exchanger for heat exchanging the boil-off gas, which has been compressed in multiple stages by means of the plurality of compressors, and the boil-off gas discharged from the storage tank; a first expanding means for expanding a part of the boil-off gas that has been compressed by means of the plurality of compressors and then has passed through the heat exchanger; a first intermediate cooler for lowering the temperature of the other part of the boil-off gas that has been compressed by means of the plurality of compressors and then has passed through the heat exchanger; a second expanding means for expanding a part of the boil-off gas that has passed through the first intermediate cooler; a second intermediate cooler for lowering the temperature of the other part of the boil-off gas that has passed through the first intermediate cooler; and a third expanding means for expanding the boil-off gas that has passed through the second intermediate cooler, wherein the boil-off gas that has been expanded by means of the first expanding means is used as a refrigerant in the first intermediate cooler, and the boil-off gas that has been expanded by means of the second expanding means is used as a refrigerant in the second intermediate cooler.
(FR)L'invention concerne un dispositif de reliquéfaction utilisant un gaz d'évaporation comme fluide de refroidissement de façon à reliquéfier le gaz d'évaporation généré à partir d'un réservoir de stockage de gaz liquéfié situé dans un navire. Un dispositif de reliquéfaction de gaz d'évaporation servant à un navire comprend : une pluralité de compresseurs servant à comprimer, dans de multiples étages, un gaz d'évaporation évacué d'un réservoir de stockage ; un échangeur de chaleur servant à l'échange de chaleur du gaz d'évaporation, qui a été comprimé dans de multiples étages au moyen de la pluralité de compresseurs, et du gaz d'évaporation évacué du réservoir de stockage ; un premier moyen de dilatation servant à dilater une partie du gaz d'évaporation qui a été comprimé au moyen de la pluralité de compresseurs et est passé à travers l'échangeur de chaleur ; un premier refroidisseur intermédiaire servant à abaisser la température de l'autre partie du gaz d'évaporation qui a été comprimé au moyen de la pluralité de compresseurs et est passé à travers l'échangeur de chaleur ; un deuxième moyen de dilatation servant à dilater une partie du gaz d'évaporation qui est passé à travers le premier refroidisseur intermédiaire ; un second refroidisseur intermédiaire servant à abaisser la température de l'autre partie du gaz d'évaporation qui est passé à travers le premier refroidisseur intermédiaire ; et un troisième moyen de dilatation servant à dilater le gaz d'évaporation qui est passé à travers le second refroidisseur intermédiaire, le gaz d'évaporation qui a été dilaté à l'aide du premier moyen de dilatation étant utilisé comme réfrigérant dans le premier refroidisseur intermédiaire, et le gaz d'évaporation qui a été dilaté à l'aide du deuxième moyen de dilatation étant utilisé comme réfrigérant dans le second refroidisseur intermédiaire.
(KO)선박에 설치된 액화가스 저장탱크에서 발생하는 증발가스를 재액화하기 위하여 증발가스를 냉각 유체로 사용하는 재액화 장치가 개시된다. 상기 선박용 증발가스 재액화 장치는, 상기 저장탱크로부터 배출되는 증발가스를 다단계로 압축시키는 다수개의 압축기; 상기 다수개의 압축기에 의해 다단계로 압축된 증발가스와 상기 저장탱크로부터 배출되는 증발가스를 열교환시키는 열교환기; 상기 다수개의 압축기에 의해 압축된 후 상기 열교환기를 통과한 증발가스의 일부를 팽창시키는 제 1 팽창수단; 상기 다수개의 압축기에 의해 압축된 후 열교환기를 통과한 증발가스의 다른 일부의 온도를 낮추는 상기 제 1 중간냉각기; 상기 제 1 중간냉각기를 통과한 증발가스의 일부를 팽창시키는 제 2 팽창수단; 상기 제 1 중간냉각기를 통과한 증발가스의 다른 일부의 온도를 낮추는 제 2 중간냉각기; 및 상기 제 2 중간냉각기를 통과한 증발가스를 팽창시키는 제 3 팽창수단;을 포함하고, 상기 제 1 팽창수단에 의해 팽창된 증발가스는 상기 제 1 중간냉각기에서 냉매로 사용되고, 상기 제 2 팽창수단에 의해 팽창된 증발가스는 상기 제 2 중간냉각기에서 냉매로 사용된다.
