Title:
周囲空気を用いたLNGの直接及び間接併用再ガス化
Document Type and Number:
Japanese Patent JP2009530549
Kind Code:
A
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.
