A ship boil-off gas reliquefaction system is disclosed. A boil-off gas reliquefaction system according to the present invention may comprise: a compression unit that compresses boil-off gas in multiple stages, including a first compressor that receives and compresses the boil-off gas generated from liquefied gas in a cargo tank provided on a ship, and a second compressor that compresses the boil-off gas generated from liquefied gas in a cargo tank provided on the ship; a second compressor for further compressing the boil-off gas compressed in the first compressor; an intercooler receiving and cooling the boil-off gas compressed in the first compressor and then supplying the boil-off gas to the second compressor; a condenser that cools the boil-off gas compressed by the compression unit; a reliquefied gas recovery line that transfers the reliquefied gas cooled and condensed in the condenser to a cargo tank after cold and heat recovery by the intercooler; and a first temperature control line that shunts the liquefied gas from the reliquefied gas recovery line and ejects the liquefied gas onto the top of the intercooler.
公开一种船舶蒸发气体再液化系统。根据本发明的蒸发气体再液化系统可包括:压缩部,以多级对蒸发气体进行压缩,包括第一压缩机及第二压缩机,第一压缩机接收并压缩由设置在船舶上的货舱罐中的经液化气体产生的蒸发气体,第二压缩机对在第一压缩机中压缩的蒸发气体进行进一步压缩;中间冷却器,接收并冷却在第一压缩机中压缩的蒸发气体且然后将蒸发气体供应到第二压缩机;冷凝器,将通过压缩部压缩的蒸发气体冷却;经再液化气体回收管线,在通过中间冷却器进行冷热量回收之后将在冷凝器中已冷却及冷凝的经液化气体转移到货舱罐;及第一温度控制管线,从经再液化气体回收管线分流出经液化气体并将经液化气体喷出到中间冷却器的顶部上。
