Patent ID: 8826673

Claim:
An LNG regasification system, comprising: an LNG source configured to provide LNG to first and second ambient air vaporizers, wherein the first and second ambient air vaporizers are configured to provide vaporized LNG; a heater fluidly coupled to the first and second ambient air vaporizers, wherein the heater is configured to receive and heat a portion of the vaporized LNG to a temperature at or above ambient temperature to thereby form a heated vaporized LNG; wherein first and second ambient air vaporizers are further thermally coupled to respective first and second defrosting conduits that are configured receive at least a portion of the heated vaporized LNG to thereby allow defrosting of the first and second ambient air vaporizers and to thereby form chilled vaporized LNG; first and second recycle conduits fluidly coupled to the first and second defrosting conduits and configured to feed at least a portion of the chilled vaporized LNG to a conduit transporting the vaporized LNG and a conduit transporting the LNG; and a third recycle conduit fluidly coupled to the defrosting conduits and configured to allow a combination of another portion of the chilled vaporized LNG with the heated vaporized LNG.
