The present invention relates to a system and a method for producing plain water of an FLNG, which are to produce plain water using temperature difference of seawater supplied to an FLNG in the FLNG. According to the present invention, the method for producing plain water of an FLNG includes: a step of evaporating a liquid working fluid of the FLNG by exchanging heat of the surface layer water and the working fluid; a step of generating electric energy using the evaporated working fluid; a step of liquefying the working fluid generating the electric energy; a step of evaporating the surface layer water in which the working fluid is evaporated; and a step of producing the plain water by liquefying the evaporated surface layer water. The produced plain water is supplied to a plain water demanding place of the FLNG, and a least a part of the produced plain water is supplied to the plain water demanding placed on the ground.
본 발명은 FLNG에서 FLNG로 공급되는 해수의 온도 차를 이용하여 담수를 생산하는 FLNG의 담수 생산시스템 및 그 방법에 관한 것이다. 본 발명에 따르면, FLNG의 액체 상태의 작동유체를 표층수와 열교환시켜 기화시키는 단계; 상기 기화된 작동유체로 전기 에너지를 생산하는 단계; 상기 전기 에너지를 생산한 작동유체를 액화시키는 단계; 상기 작동유체를 기화시킨 표층수를 증발시키는 단계; 및 상기 기화된 표층수를 액화시켜 담수를 생산하는 단계;를 포함하고, 상기 생산된 담수는 FLNG의 담수 수요처로 공급하고, 상기 생산된 담수의 적어도 일부는 육상의 담수 수요처로 공급하는 FLNG의 담수 생산방법이 제공된다.
