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; a bypass line for enabling the boil-off gas to bypass the heat exchanger and be supplied to the compressor; a second valve for controlling fluid flow and opening/closing, which is installed on a second supply line for transferring, to the compressor, the boil-off gas used as a refrigerant in the heat exchanger; and a decompressing device installed at the rear end of the heat exchanger, and decompressing the fluid cooled by the heat exchanger, wherein the compressor comprises at least one oil-lubricated cylinder, and the bypass line converges into the second supply line at the rear end of the second valve.
(FR) La présente invention concerne un système de reliquéfaction de gaz d'évaporation. Le système de reliquéfaction de gaz d'évaporation comprend : un compresseur pour comprimer un gaz d'évaporation ; un échangeur de chaleur pour soumettre le gaz d'évaporation comprimé par le compresseur à un échange de chaleur et ainsi refroidir celui-ci, en utilisant le gaz d'évaporation avant d'être comprimé par le compresseur en tant que fluide frigorigène ; une conduite de dérivation pour permettre au gaz d'évaporation de contourner l'échangeur de chaleur et d'être fourni au compresseur ; une seconde soupape pour commander l'écoulement de fluide et l'ouverture/fermeture, qui est installée sur une seconde ligne d'alimentation pour transférer, au compresseur, le gaz d'évaporation utilisé comme fluide frigorigène dans l'échangeur de chaleur ; et un dispositif de décompression installé à l'extrémité arrière de l'échangeur de chaleur et décompressant le fluide refroidi par l'échangeur de chaleur, le compresseur comprenant au moins un cylindre lubrifié à l'huile et la conduite de dérivation convergeant dans la seconde ligne d'alimentation au niveau de l'extrémité arrière de la seconde soupape.
