Abstract: front page image
(EN) The present invention relates to an apparatus and a method for reliquefaction of boil-off gas generated in a liquefied gas storage tank applied to a vessel. The apparatus for reliquefaction of boil-off gas for a vessel, according to the present invention, which is a reliquefaction apparatus for reliquefying boil-off gas generated in a liquefied gas storage tank installed on a vessel, comprises: a compression unit for compressing the boil-off gas discharged from the storage tank; and a heat exchanger for heat-exchanging the compressed boil-off gas compressed by the compression unit with the boil-off gas discharged from the storage tank, wherein the apparatus for reliquefaction of boil-off gas for a vessel further comprises: a first expansion means for dividing the boil-off gas passing through the heat exchanger into at least two flows including a first flow and a second flow, and expanding the divided first flow; a first intercooler for cooling the second flow remaining after the division of the first flow by using the first flow expanded by the expansion means as a refrigerant; and a receiver for receiving a second flow having passed through the first intercooler, in which a downstream pressure of the compression unit is controlled by a flow discharged from the receiver.
(FR) La présente invention concerne un appareil et un procédé de reliquéfaction de gaz d'évaporation généré dans un réservoir de stockage de gaz liquéfié appliqué à un récipient. L'appareil de reliquéfaction de gaz d'évaporation pour un récipient, selon la présente invention, qui est un appareil de reliquéfaction pour reliquéfaction du gaz d'évaporation généré dans un réservoir de stockage de gaz liquéfié installé sur un récipient, comprend : une unité de compression pour comprimer le gaz d'évaporation évacué du réservoir de stockage ; et un échangeur de chaleur pour échanger de la chaleur entre le gaz d'évaporation comprimé, comprimé par l'unité de compression et le gaz d'évaporation évacué du réservoir de stockage, l'appareil de reliquéfaction de gaz d'évaporation pour un récipient comprenant en outre : un premier moyen d'expansion pour diviser le gaz d'évaporation passant à travers l'échangeur de chaleur en au moins deux flux comprenant un premier flux et un second flux et étendre le premier flux divisé ; un premier refroidisseur intermédiaire pour refroidir le second flux restant après la division du premier flux en utilisant le premier flux expansé par le moyen d'expansion en tant que fluide frigorigène ; et un récepteur pour recevoir un second flux ayant traversé le premier refroidisseur intermédiaire, dans lequel une pression aval de l'unité de compression est régulée par un flux évacué du récepteur.
(KO) 본 발명은 선박에 적용되는 액화가스 저장탱크에서 발생하는 증발가스의 재액화 장치 및 방법에 관한 것이다. 본 발명에 따른 선박용 증발가스 재액화 장치는,선박에 설치된 액화가스 저장탱크에서 발생하는 증발가스를 재액화하기 위한 재액화 장치에 있어서, 상기 저장탱크로부터 배출되는 증발가스를 압축하는 압축부; 및 상기 압축부에 의해 압축된 압축 증발가스와 상기 저장탱크로부터 배출되는 증발가스를 열교환시키는 열교환기;를 포함하며, 상기 열교환기를 통과한 증발가스를 제1 흐름 및 제2 흐름을 포함하는 적어도 두 개의 흐름으로 분기시키고, 상기 분기된 제1 흐름을 팽창시키는 제1 팽창수단; 상기 팽창수단에 의해 팽창된 제1 흐름을 냉매로 하여 상기 제1 흐름이 분기되고 남은 제2 흐름을 냉각시키는 제1 중간 냉각기; 및 상기 제1 중간 냉각기를 통과한 제2 흐름을 수용하는 리시버;를 더 포함하고, 상기 리시버로부터 배출되는 흐름에 의해 상기 압축부 후단 압력이 제어되는 것을 특징으로 한다.
