Disclosed is a liquefied gas regasification system to produce electricity by using a thermal medium. According to one embodiment of the present invention, the liquefied gas regasification system comprises: first and second heat exchangers to sequentially perform heat exchange between liquefied gas supplied from a storage tank and a thermal medium; a regasification line to supply the liquefied gas gasified through the first and second heat exchangers to a customer; a first circulation line to circulate a first thermal medium among the thermal media supplied from a suction drum to the suction drum through the first heat exchanger; a second circulation line branched from the first circulation line to sequentially circulate the second thermal medium among the thermal media to the suction drum through the second and first heat exchangers; a first heater disposed on the first circulation line and exchanging heat between the first thermal medium and a heat source; a first expander to expand and transfer the heat exchanged first thermal medium to the first heat exchanger; a first generator connected to the first expander to produce electricity; and a second heater disposed on the second circulation line and exchanging heat between the second thermal medium and the heat source to transfer the heat exchanged second thermal medium to the second heat exchanger.

    액화가스 재기화 시스템이 개시된다. 본 발명의 일 실시 예에 의한 액화가스 재기화 시스템은 저장탱크로부터 공급받은 액화가스와 열매체 간 순차적으로 열교환을 수행하는 제1열교환기 및 제2열교환기; 제1열교환기 및 제2열교환기를 거쳐 기화된 액화가스를 수요처로 공급하는 재기화라인; 석션드럼으로부터 공급받은 열매체 중 제1열매체를 제1열교환기를 거쳐 석션드럼으로 순환시키는 제1순환라인; 제1순환라인으로부터 분기되어, 열매체 중 제2열매체를 제2열교환기와 제1열교환기를 순차적으로 거쳐 석션드럼으로 순환시키는 제2순환라인; 제1순환라인에 마련되며, 제1열매체를 열원과 열교환하는 제1가열기; 열교환된 제1열매체를 팽창시켜 제1열교환기로 보내는 제1팽창기; 제1팽창기와 연결되어 전기를 생산하는 제1발전기; 및 제2순환라인에 마련되며, 제2열매체를 열원과 열교환하여 제2열교환기로 보내는 제2가열기;를 포함한다.
