The invention discloses a boil-off gas treatment system and method for a ship. The system for treating boil-off gas of a ship according to the present invention comprises: a first compressor for receiving and compressing boil-off gas generated from liquefied gas stored in a storage tank of a ship; a second compressor receiving and compressing the boil-off gas from the storage tank; a heat exchanger in which the boil-off gas compressed in the first compressor or the second compressor is cooled; and a refrigerant circulation line through which the refrigerant supplied to the heat exchanger circulates, in which the first compressor is a multi-stage compressor that compresses the boil-off gas to a fuel supply pressure of the ship propulsion engine by the plurality of compressors, and the second compressor is a multi-stage compressor that compresses the boil-off gas to a fuel supply pressure of the ship propulsion engine by the plurality of compressors. The second compressor compresses the boil-off gas to a fuel supply pressure of a power generation engine supplied with fuel at a pressure lower than a pressure of the propulsion engine, and the boil-off gas compressed by some stages of the first compressor may be supplied to the heat exchanger for cooling or to the power generation engine.

    本发明公开一种船只的蒸发气体处理系统和方法。本发明的用于处理船只的蒸发气体的系统包括:第一压缩机,接收且压缩由存储于船只的存储罐中的液化气体产生的蒸发气体;第二压缩机,接收且压缩来自存储罐的蒸发气体;热交换器,在第一压缩机或第二压缩机中压缩的蒸发气体在所述热交换器中冷却;以及制冷剂循环管线,供应到热交换器的制冷剂通过所述制冷剂循环管线循环,其中第一压缩机为多级压缩机,其通过多个压缩机将蒸发气体压缩到船上推进发动机的燃料供应压力,第二压缩机将蒸发气体压缩到在比推进发动机的压力低的压力下供应有燃料的发电发动机的燃料供应压力,且通过第一压缩机的一些级压缩的蒸发气体可供应到热交换器以进行冷却或供应到发电发动机。
