Abstract:
(EN) A boil-off gas reliquefaction system is disclosed. The boil-off gas reliquefaction system comprises: a compressor for compressing boil-off gas; a heat exchanger for subjecting the boil-off gas compressed by the compressor to heat exchange, and thus cooling same, by using the boil-off gas before being compressed by the compressor as a refrigerant; and a decompressing device installed at the rear end of the heat exchanger, and decompressing the fluid cooled by the heat exchanger. The boil-off gas reliquefaction system comprises at least one among: a first temperature sensor installed at the front end of a low-temperature flow path of the heat exchanger, and a fourth temperature sensor installed at the rear end of a high-temperature flow path of the heat exchanger; a second temperature sensor installed at the rear end of the low-temperature flow path of the heat exchanger, and a third temperature sensor installed at the front end of the high-temperature flow path of the heat exchanger; and a first pressure sensor installed at the front end of the high-temperature flow path of the heat exchanger, and a second pressure sensor installed at the rear end of the high-temperature flow path of the heat exchanger. The compressor comprises at least one oil-lubricated cylinder.
(FR) La présente invention concerne un système de reliquéfaction de gaz d'évaporation. Le système de reliquéfaction de gaz d'évaporation comporte: un compresseur pour la compression de gaz d'évaporation; un échangeur de chaleur pour le traitement du gaz d'évaporation comprimé par le compresseur par échange de chaleur, et donc son refroidissement, en utilisant le gaz d'évaporation avant sa compression par le compresseur en tant que réfrigérant; et un dispositif de décompression installé à l'extrémité arrière de l'échangeur de chaleur, et effectuant une décompression du fluide refroidi par l'échangeur de chaleur. Le système de reliquéfaction de gaz d'évaporation comporte au moins un parmi: un premier capteur de température installé à l'extrémité avant d'un trajet d'écoulement à basse température de l'échangeur de chaleur, et un quatrième capteur de température installé à l'extrémité arrière d'un trajet d'écoulement à haute température de l'échangeur de chaleur; un deuxième capteur de température installé à l'extrémité arrière du trajet d'écoulement à basse température de l'échangeur de chaleur, et un troisième capteur de température installé à l'extrémité avant du trajet d'écoulement à haute température de l'échangeur de chaleur; et un premier capteur de pression installé à l'extrémité avant du trajet d'écoulement à haute température de l'échangeur de chaleur, et un second capteur de pression installé à l'extrémité arrière du trajet d'écoulement à haute température de l'échangeur de chaleur. Le compresseur comporte au moins un cylindre lubrifié à l'huile.
