Abstract:
PROBLEM TO BE SOLVED: To provide a gas reliquefaction method with high liquefaction efficiency, for obtaining a large amount of a liquid flow by a lightweight and inexpensive device composition, and for realizing isenthalpic expansion. SOLUTION: A gas flow from a storage container is compressed after heating by heat exchange, and it is expanded and re-liquefied after cooling. Only a partial flow 4 which is one part of a whole gas flow amount 1 and 2 from the storage container is sent to processes after compression V. A partial flow 3 not sent to the processes after compression of the whole gas flow amount 1 and 2 from the storage container is sent to an energy conversion process by a fuel cell or a Stirling engine, a direct vapor generation process, and a vapor process or a gas turbine process, or it is stored.
