PROBLEM TO BE SOLVED: To provide an LNG vaporization system in which power consumption of a seawater pump occupying the half or more of the vaporizer power is reduced and a total quantity of consumed energy is also reduced, by using an expander. SOLUTION: This LNG vaporization system is provided with the vaporizer 2 vaporizing the liquefied natural gas using fluid and a pump 4 for delivering the fluid, vaporizes the liquefied natural gas 71, and provides delivery natural gas 78. This system is provided with the expander 3 taking out the power for rotating the pump 4 using a pressure difference of incoming and outgoing gas 76 and 77. The natural gas 76 vaporized by the vaporizer 2 has higher pressure than that of the delivered natural gas 78. COPYRIGHT: (C)2003,JPO
