Title:
PROCESS FOR UNLOADING PRESSURIZED LNG FROM CONTAINERS
Document Type and Number:
WIPO Patent Application WO2000036332
Kind Code:
A3
Abstract:
A process is disclosed for unloading a plurality of containers (1, 2) having pressurized liquefied gas contained therein. A pressurized displacement gas (10) is fed to a first container or group of containers to discharge the liquefied gas therefrom. The displacement gas is then withdrawn from the first containers or group and is separated into a first vapor stream and a second vapor stream. The first vapor stream is heated (52) and passed to the first container or group. The second vapor stream is fed to a second container or group to discharge liquefied gas therefrom. Communication between the first container or group and the second container or group is severed and the foregoing steps are repeated for all of the containers in succession, with only the last container or group emptied of liquid remaining at the pressure of the displacement gas, and all of the containers at the end of the process except the last container or group being filled with a lower pressure vapor.
