    Abstract: A process and apparatus for regasification of LNG to form natural gas using ambient air as the primary source of heat are described. LNG is directed to flow through an ambient air vaporizer to form a natural gas stream through direct heat exchange between the LNG and ambient air. The temperature of the natural gas stream is adjusted to suit a predetermined delivery temperature in a trim heater exchanging heat with a circulating intermediate fluid. The intermediate fluid is directed to flow through an ambient air heater such that the intermediate fluid exchanges heat with ambient air. Heat transfer between the ambient air and the LNG is assisted using one or more force draft fans to direct the flow of ambient air over the ambient air heater and the ambient air vaporizer in turn to dry the ambient air before it arrives at the ambient air vaporizer.

    Abstract translation: 描述了使用环境空气作为主要热源的LNG再气化以形成天然气的方法和装置。 LNG被引导流过环境空气蒸发器以通过LNG和环境空气之间的直接热交换形成天然气流。 调节天然气流的温度以适应与循环中间流体交换热量的修整加热器中的预定输送温度。 中间流体被引导流过环境空气加热器,使得中间流体与环境空气交换热量。 环境空气和LNG之间的热传递通过使用一个或多个强制通风风扇来辅助,以引导环境空气流过环境空气加热器和环境空气蒸发器,从而在环境空气到达环境空气蒸发器之前干燥环境空气 。
