PROBLEM TO BE SOLVED: To provide a liquefied gas treatment system for a vessel mounted with a storage tank to store liquefied natural gas and an engine which uses the liquefied natural gas stored in the storage tank as fuel.SOLUTION: A liquefied gas treatment system includes: a first stream where boil-off gas is generated from liquefied natural gas in a storage tank and discharged from the same; a second stream for a portion of the boil-off gas in the first stream which is supplied to an engine as fuel; and a third stream for the portion of the boil-off gas in the first stream which is not supplied to the engine. The first stream is divided into the second stream and the third stream after the boil-off gas in the first stream is compressed by a compressor. In the third stream, the boil-off gas is liquefied by exchanging heat with the first stream in a heat exchanger. Thus, the liquefied gas treatment system can treat the boil-off gas without using a liquefier requiring an additional coolant.SELECTED DRAWING: Figure 2

    【課題】液化天然ガスを貯蔵する貯蔵タンクと、前記貯蔵タンクに貯蔵されている液化天然ガスを燃料として使用するエンジンとを備えた船舶の液化ガス処理システムを提供する。【解決手段】前記液化ガス処理システムは、前記貯蔵タンク内で液化天然ガスから発生した後、前記貯蔵タンクから排出されるボイルオフガスの第1ストリームと、前記第1ストリームのうち燃料として前記エンジンに供給されるボイルオフガスの第2ストリームと、及び前記第1ストリームのうち前記エンジンに供給されないボイルオフガスの第3ストリームとを含む。前記第1ストリームは、圧縮装置で圧縮された後、前記第2ストリームと前記第3ストリームとに分岐される。前記第3ストリームは、熱交換器で前記第1ストリームと熱交換されて液化されることによって別途の冷媒を用いた再液化装置を使用することなくボイルオフガスを処理できる。【選択図】図2
