Abstract:
A compact, lightweight yet high capacity gas storage and delivery apparatus for storing cryogenic temperature mixed gas capable of gas component separation during storage and delivery of the mixed gas at a usable temperature and an unenriched state comprising:a containment vessel including pressure maintenance means for accommodating receipt at said containment vessel of mixed gas supplied at cryogenic temperature and at or above supercritical pressure so that the cryogenic temperature mixed gas remains, at the time of being received in said containment vessel, at or above supercritical pressure and thus in a single phase; an outer shell around said containment vessel providing a vacuum jacket; outlet means connected with said containment vessel for selective expulsion of the mixed gas from said containment vessel therethrough; and passive heat exchange means substantially entirely integrated within said outer shell and connected with said outlet means for receiving the expelled mixed gas at said outlet means and conducting the expelled mixed gas to a destination for use, said heat exchange means being routed for introducing heat from said outer shell to said containment vessel during conduct of the expelled mixed gas to said destination and having capacity calculated for such introduction of heat into said containment vessel to maintain the mixed gas remaining in said containment vessel in a single phase and with sufficient continued expulsion pressure based substantially solely on rate of expulsion of the mixed gas from said containment vessel through said outlet means.
