Abstract
A method and apparatus for unloading natural gas (NG), including gasifying liquid and/or compressed NG using the latent heat of water and propane, and/or storing liquid or compressed NG gas in a storage cavern system that utilizes a buffer layer to prevent hydrating the NG gas, the storage cavern system being configured such that the NG may be forced out of a first storage chamber by increasing the amount of brine in a second chamber to displace a buffer fluid located therein such that the displace buffer fluid enters the first storage chamber and displaces the NG, as well as the processes for compressing, chilling and/or liquefying quantities of LNG and transporting those volumes to markets for redelivery.
