ABSTRACT:
Disclosed is an apparatus for storing and delivering a liquid cryogen. The apparatus is a dewar having a rotating liquid cryogen intake, a rotating gas supply vent, and a rotating capacitance gauge. Also disclosed is a system and a process employing the system for liquefying a gas to produce a liquid cryogen in the dewar wherein the gas is subcritically cooled and then condensed in the pressure vessel of the dewar.
