The present invention relates to a treatment system of liquefied gas comprising: a boil-off gas supply line connected from a storage tank of liquefied gas to a demander; a boil-off gas compressor arranged on top of the boil-off gas supply line, and compressing the boil-off gas; a liquefied gas supply line connected from the storage tank of liquefied gas to the boil-off gas supply line; a forcing vaporizer arranged on top of the liquefied gas supply line and the boil-off gas supply line, and heating liquefied gas and boil-off gas discharged from the storage tank of liquefied gas; and a heat medium supply part to supply heat to the forcing vaporizer generating power using the cold energy of the liquefied gas and the boil-off gas. According to the present invention, the treatment system of liquefied gas can efficiently use the discarded cold energy of the liquefied gas or the boil-off gas by installing a BOG/LNG/heat medium heat exchanger or installing the BOG/heat medium heat exchanger and an LNG/heat medium heat exchanger as a forcing vaporizer between the storage tank of liquefied gas and the boil-off gas compressor. In addition, costs to operate the system can significantly be reduced as the heat medium used to heat the liquefied gas or a circulation of boil-off gas flows and generates power by generating energy during an expansion of the heat medium.

    본 발명은 액화가스 처리 시스템에 관한 것으로서, 액화가스 저장탱크로부터 수요처까지 연결된 증발가스 공급라인; 상기 증발가스 공급라인 상에 마련되며 증발가스를 압축하는 증발가스 압축기; 상기 액화가스 저장탱크로부터 상기 증발가스 공급라인까지 연결된 액화가스 공급라인; 상기 액화가스 공급라인과 상기 증발가스 공급라인 상에 마련되며, 상기 액화가스 저장탱크로부터 배출된 액화가스 및 증발가스를 가열하는 강제 기화기; 및 상기 강제 기화기에 열을 공급하며, 상기 액화가스와 상기 증발가스의 냉열을 이용하여 동력을 생성하는 열매 공급부를 포함하는 것을 특징으로 한다. 본 발명에 따른 액화가스 처리 시스템은, 액화가스 저장탱크와 증발가스 압축기 사이에 강제 기화기로서, BOG/LNG/열매 열교환기를 설치하거나, BOG/열매 열교환기와 LNG/열매 열교환기를 설치함으로써, 액화가스 또는 증발가스의 버려지는 냉열을 효율적으로 이용할 수 있고, 액화가스 또는 증발가스를 가열하기 위해 사용되는 열매가 순환 유동하도록 하되, 열매의 팽창 시 에너지가 생성되도록 하여 발전을 수행할 수 있어, 시스템 운영 비용을 현저히 감축할 수 있다.
