Abstract
Disclosed herein are methods and systems for storing and withdrawing a light gas such as helium or hydrogen in an underground formation. The method includes pumping a cryogenic liquid stream to produce a pumped liquid stream, and vaporizing the pumped liquid stream to produce a first-high pressure gas steam. The method further includes feeding the first high-pressure gas stream to a gas storage cavern.
Claims20
A method comprising:
- pumping a cryogenic liquid stream to produce a pumped liquid stream;
- vaporizing the pumped liquid stream to produce a first high-pressure gas stream;
- and
- feeding the first high-pressure gas stream to a gas storage cavern.
1 more element
A method comprising:
- removing a withdrawal gas stream from a gas storage cavern;
- cooling the withdrawal gas stream to produce a condensate stream and an overhead stream;
- and
- returning the condensate stream to the gas storage cavern.
1 more element
A system for storing a cryogenic liquid comprising:
- a cryogenic pump in fluid flow communication with a cryogenic liquid source, wherein the cryogenic pump is configured to pump a cryogenic liquid stream and produce a pumped liquid stream;
- a high-pressure vaporizer in fluid flow communication with the cryogenic pump, wherein the high-pressure vaporizer is configured to vaporize the pumped liquid stream and produce a high-pressure gas stream;
- and
- a gas storage cavern in fluid flow communication with the high-pressure vaporizer, wherein the gas storage cavern is configured to accept the high-pressure gas stream.
