Abstract:
A flexible natural gas storage facility comprising:at least one man-made salt cavern; a pipeline source of a first fluid; at least one high pressure compressor to compress the first fluid; at lease one heat exchanger to cool the first fluid from the compressor to a temperature that is compatible with the salt cavern, before the first fluid is placed in the salt cavern for storage; a source of a second fluid; at least one high pressure cryogenic pump to raise the pressure of the second fluid to dense phase; at least one Bishop Process heat exchanger to heat the second fluid to a temperature that is compatible with the salt cavern, before the second fluid is placed in the salt cavern for storage; and at least one high pressure vaporizer to heat the second fluid from the high pressure LNG pump to a temperature that is compatible with the salt cavern, before the second fluid is placed in the salt cavern for storage.
