The present invention relates to an evaporation gas processing system for a marine structure capable of effectively using an evaporation gas by using most of the evaporation gas discharged from a storing tank as fuel for a natural gas injecting engine of a vessel after pressing, partly liquefying the remaining evaporation gas using cold heat of evaporation gas newly discharged from the storing tank, and returning the liquefied evaporation gas to the storing tank. The evaporation gas processing system for a marine structure includes the storing tank receiving LPG and a high-pressure natural gas injecting engine using the evaporation gas discharged from the storing tank. According to the present invention, the evaporation gas processing system for a marine structure including a compressor receiving the evaporation gas generated inside the storing tank and compressing the received air; the high-pressure natural gas injecting engine receiving and using the evaporation gas compressed by the compressor as fuel; a heat exchanger to cool some of the evaporation gas not supplied to the high-pressure natural gas injection engine; and an expanding device generating energy while expanding the evaporation gas cooled by the heat exchanger is provided.

    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.
