Abstract:
A system comprising:(a) pressurized liquefied natural gas at a pressure of about 1035 kPa (150 psia) to about 7590 kPa (1100 psia) and at a temperature of about âˆ’123Â° C. (âˆ’190Â° F.) to about âˆ’62Â° C. (âˆ’80Â° F.) stored in one or more PLNG Containers having adequate strength and toughness to contain said pressurized liquefied natural gas at said pressure and temperature conditions; (b) one or more LNG Containers suitable for storing liquefied natural gas at substantially atmospheric pressure and at a temperature of about âˆ’162Â° C. (âˆ’260Â° F.); (c) means for removing and reducing the pressure of at least a portion of said pressurized liquefied natural gas from said one or more PLNG Containers, which removed pressurized liquefied natural gas comprises a substantially gaseous portion and a substantially liquid portion; (d) separation equipment suitable for separating said substantially gaseous portion and said substantially liquid portion; (e) pressurization equipment suitable for pressurizing said substantially gaseous portion to a desired pressure; (f) gas delivery equipment suitable for delivering said pressurized substantially gaseous portion to a gaseous portion destination; (g) depressurization equipment suitable for reducing the pressure of said substantially liquid portion to substantially atmospheric pressure in one or more steps; and (h) liquid delivery equipment suitable for delivering said substantially atmospheric pressure liquid portion to said one or more LNG Containers.
