摘要： A cryogenic vessel features an inner tank containing cryogenic liquid with a head space above and a jacket surrounding the inner tank. An internal pressure builder coil is helically disposed about the inner tank, connected to the jacket and in communication with the bottom of the inner tank. An external pressure building heat exchanger is connected to the internal pressure builder coil and the head space of the inner tank. Liquid from the inner tank flows into the internal pressure builder coil and the exiting fluid is driven by a resulting pumping action to the external pressure building heat exchanger where it is vaporized and warmed. The warmed gas is directed to the head space of the inner tank to rapidly build the pressure therein. Gas may be dispensed directly from the head space of the vessel via an economizer valve. Alternatively, liquid may be withdrawn from the inner tank by a dip tube and vaporized in a vaporizer and dispensed.
