ABSTRACT:
Liquefied natural gas is regasified to form natural gas, including circulation of an intermediate fluid between a vaporizer and an ambient air heater, where the intermediate fluid is warmed by exchanging heat with the ambient air as the intermediate fluid passes through the ambient air heater, and the intermediate fluid is cooled by exchanging heat with LNG as the intermediate fluid passes through the vaporizer. The ambient air heater is subjected to a defrosting cycle by intermittently regulating the temperature of the intermediate fluid fed to the ambient air heater to a temperature greater than zero degrees Celsius using a source of supplemental heat.
