Regasification of LNG using dehumidified air

A process for regasification of LNG to form natural gas using ambient air as a primary source of heat, said process comprising:

• (a) directing LNG to flow through an ambient air vaporizer to form a natural gas stream through heat exchange between the LNG and ambient air;
• (b) adjusting the temperature of the natural gas stream to a predetermined delivery temperature in a trim heater by exchanging heat with a circulating intermediate fluid, wherein the trim heater is separate from the ambient air vaporizer such that the natural gas stream exits the ambient air vaporizer prior to entering and being treated in the trim heater;
• (c) directing the intermediate fluid to flow through an ambient air heater such that the intermediate fluid exchanges heat with ambient air;
• and,
• (d) assisting heat transfer using one or more force draft fans to direct the flow of ambient air over the ambient air heater and the ambient air vaporizer, the ambient air heater being arranged in closer proximity to the forced draft fans than the ambient air vaporizer such that the air is directed to flow across the ambient air heater to cool and dry the air before the air arrives at the ambient air vaporizer.
