Title (EN) SYSTEM AND METHOD FOR TREATING BOIL-OFF GAS IN SHIP
(FR) SYSTÈME ET PROCÉDÉ POUR TRAITER UN GAZ D'ÉVAPORATION DANS UN NAVIRE
(KO) 선박의 증발가스 처리 시스템 및 방법
Abstract: front page image
(EN)Disclosed are a system and method for treating boil-off gas in a ship, which use a portion of gas, which has been discharged from a storage tank and compressed, as fuel for a ship's engine and liquefy the remainder by using the coldness of boil-off gas that is freshly discharged from the storage tank so as to return the remainder to the storage tank, thereby allowing boil-off gas to be efficiently used. The system for treating boil-off gas in a ship according to the present invention comprises: compressing means for receiving and compressing boil-off gas discharged from the storage tank; an intermediate pressure gas engine for receiving at least a portion of boil-off gas from the boil-off gas compressed by the compressing means as fuel; heat exchange means for performing heat exchange on the remaining boil-off gas that has not been supplied as fuel to the intermediate pressure gas engine and boil-off gas that has been discharged from the storage tank and has not been compressed; and expansion means for reducing the pressure of the remaining boil-off gas cooled by the heat exchange means.
(FR)L'invention concerne système et un procédé pour traiter un gaz d'évaporation dans un navire, qui utilisent une partie de gaz, qui a été déchargé d'un réservoir de stockage et comprimé, comme combustible pour un moteur d'un navire et liquéfient le reste à l'aide de la froideur du gaz d'évaporation qui est déchargé fraîchement du réservoir de stockage de façon à renvoyer le reste au réservoir de stockage, permettant ainsi au gaz d'évaporation d'être utilisé efficacement. Le système pour traiter un gaz d'évaporation dans un navire selon la présente invention comprend : un moyen de compression pour recevoir et comprimer un gaz d'évaporation déchargé du réservoir de stockage ; un moteur à gaz de pression intermédiaire pour recevoir au moins une partie du gaz d'évaporation, provenant du gaz d'évaporation comprimé par le moyen de compression, comme combustible ; un moyen d'échange de chaleur pour réaliser un échange de chaleur sur le gaz d'évaporation restant qui n'a pas été fourni comme combustible au moteur à gaz de pression intermédiaire, et le gaz d'évaporation qui a été déchargé du réservoir de stockage et n'a pas été comprimé ; et un moyen de dilatation pour réduire la pression du gaz d'évaporation restant refroidi par le moyen d'échange de chaleur.
(KO)저장탱크에서 배출된 증발가스를 가압한 후 일부는 선박 엔진의 연료로 사용하고 나머지는 저장탱크로부터 새롭게 배출되는 증발가스의 냉열로 액화시켜 저장탱크로 복귀시킴으로써, 증발가스를 효율적으로 사용할 수 있도록 하는 선박의 증발가스 처리 시스템 및 방법이 개시된다. 본 발명에 따른 선박의 증발가스 처리 시스템은, 상기 저장탱크로부터 배출된 증발가스를 공급받아 압축하는 압축수단과; 상기 압축수단에서 압축된 증발가스 중 적어도 일부의 증발가스를 연료로서 공급받는 중압 가스 엔진과; 상기 중압 가스 엔진에 연료로서 공급되지 않은 나머지 증발가스를 상기 저장탱크에서 배출된 후 압축되기 전의 증발가스와 열교환하는 열교환수단과; 상기 열교환수단에서 냉각된 상기 나머지 증발가스의 압력을 감소시키는 팽창수단; 을 포함한다.
