LNG receiving terminal that primarily uses compensated salt cavern storage and method of use

a technology of receiving terminal and salt cavern, which is applied in the direction of container discharging methods, water supply installation, container filling under pressure, etc., can solve the problems of lng transport ships costing more than $100,000,000 to build, stranded gas produced concurrently with crude oil is often burned at a flare, and the lng transport ship may take 12 hours or more to pump lng

Abstract

In the past, “compensated” salt caverns have operated with a compensating liquid, such as brine to displace a stored liquid, such as crude oil, when the stored liquid is needed on the surface. Virtually all of the stored liquid in a compensated salt cavern can be expelled from the salt cavern when it is filled with the compensating liquid. In the past, “uncompensated” salt caverns have been used to store gases, such as natural gas. Uncompensated caverns operate without any compensating liquid; instead they rely on pressure. Some of the stored gas (cushion gas) must always be left in an uncompensated salt cavern. This invention breaks with convention and uses a compensating liquid in a salt cavern to store gases which is a technique believed to be previously unknown. “Cushion gas” is not required because the compensating liquid displaces virtually all of the gas in the salt cavern.
