摘要
PURPOSE: To reduce the construction and operation cost for liquefying facility by liquefying natural gas in a liquefying terminal on the sea at such a degree of pressure not more than the pressure that the power for liquefaction can be reduced, transporting the liquefied natural gas to a terminal on the earth by a transportation ship, and storing it in a tank at atmospheric pressure. ;CONSTITUTION: In a natural gas liquefied terminal 51 on the sea for small scale gas field, natural gas is liquefied at such a degree of pressure not more than the pressure that the power for liquefaction can be reduced by the operation of a compression refrigerating machine 64, i.e., at a pressure not more than 10kg/cm2. The liquefied natural gas is stored in a tank 55 on a transportation ship 54 by a loading arm 53 after it is once stored in a tank 52. Then, after the liquefied natural gas is moved to a receiving terminal 56 on the earth by the transportation ship 54, it is further cooled utilizing the cold of liquefied natural gas stored in a liquid air tank 100 in a liquid air generating facility 89 to store it in the tank 57 at atmospheric pressure. The liquefied natural gas in the tank 57 is removed as natural gas from a pipe 58 through an expansion turbine.;COPYRIGHT: (C)1994,JPO&Japio
