The present invention relates to a system for treating evaporation gas in a marine structure, capable of efficiently using evaporation gas by using most of the evaporation gas as fuel of a high-pressure natural gas spray engine of a vessel after compressing the evaporation gas discharged from a storage tank and by liquefying and returning the remaining part of the evaporation gas to the storage tank by the cold and heat of the evaporation gas newly discharged from the storage tank. According to the present invention, the system for treating evaporation gas in a marine structure comprises: the storage tank storing liquefied natural gas; and the high-pressure natural gas spray engine using the evaporation gas discharged from the storage tank as fuel. The system for treating evaporation gas in a marine structure also includes: a compressor receiving and compressing the evaporation gas generated in the storage tank; the high-pressure natural gas spray engine receiving and using the evaporation gas compressed by the compressor as fuel; a heat exchanger for cooling the portion of the evaporation gas which is not supplied to the high-pressure natural gas spray engine; and an expander generating energy while expanding the evaporation gas cooled by the heat exchanger.

    본 발명은 저장탱크에서 배출된 증발가스를 가압한 후 대부분은 선박의 고압 천연가스 분사 엔진의 연료로 사용하고 나머지 일부는 저장탱크로부터 새롭게 배출되는 증발가스의 냉열로 액화시켜 저장탱크로 복귀시킴으로써, 증발가스를 효율적으로 사용할 수 있도록 하는 해양 구조물의 증발가스 처리 시스템에 관한 것이다. 본 발명에 따르면, 액화천연가스를 저장하고 있는 저장탱크와, 상기 저장탱크에서 배출되는 증발가스를 연료로서 사용하는 고압 천연가스 분사 엔진을 갖춘 해양 구조물의 증발가스 처리 시스템으로서, 상기 저장탱크 내에서 발생한 증발가스를 공급받아 압축하는 압축기와; 상기 압축기에서 압축된 증발가스를 연료로서 공급받아 사용하는 상기 고압 천연가스 분사 엔진과; 상기 증발가스 중 상기 고압 천연가스 분사 엔진에 공급되지 않은 일부의 증발가스를 냉각시키기 위한 열교환기와; 상기 열교환기에서 냉각된 증발가스를 팽창시키면서 에너지를 생성하는 팽창기; 를 포함하는 것을 특징으로 하는 해양 구조물의 증발가스 처리 시스템이 제공된다.
