    摘要： A high pressure cryogenic fluid dispensing system features a tank containing a cryogenic liquid with a liquid side and a head space there above. A pressure building coil featuring a section of parallel heat exchangers and a section of series heat exchangers receives liquid from the tank through a pressure building regulator valve and a pair of surge check valves. The liquid flashes to gas in the section of parallel heat exchangers and the resulting gas is forced to the section of series heat exchangers where it is pressurized and warmed. The gas may be directed to a warming coil for dispensing and to the head space of the tank to rapidly pressurize it. Gas traveling to the head space flows through an vapor space withdrawal control valve. The vapor space withdrawal control valve and pressure building regulator valve may be automated via a controller that provides pressure building when the tank pressure drops below the system operating pressure.

    摘要： A system that generates high pressure cryogenic gas includes a storage tank that contains a liquid cryogen and a feed line that supplies the liquid cryogen to a pressure pod. The pressure in the pressure pod gradually increases due to ambient heat to a first predetermined level. A regulator valve opens at the first predetermined level thereby directing the liquid cryogen to a heat exchanger where it is vaporized and directed back to the pressure pod to raise the pressure therein further. Once the pressure in the pressure pod reaches a second predetermined level, a dispense valve opens. The pressurized liquid cryogen is directed through the dispense valve to a vaporizer that vaporizes the high pressure liquid cryogen to a cryogenic gas that may be dispensed and stored in a tank.

    摘要： A dispensing system allows cryogenic liquid to be dispensed from either a primary bank manifold and associated cylinders or a secondary bank manifold and associated cylinders. Each manifold includes a gas header and a liquid header. The associated cylinders communicate with the gas header through flexible lines and excess flow check valves and the liquid header through flexible lines and spring-loaded check valves. An automatic control system selects between dispensing from the primary bank manifold or the secondary bank manifold. A pressure gauge detects the pressure of the cryogenic liquid from the dispensing manifold. The pressure gauge is in communication with a controller which opens and closes the appropriate valves to begin dispensing cryogenic liquid from the originally idle manifold if the detected pressure drops below a predetermined minimum. After the manifold is switched over, the controller checks the pressure in the non-selected manifold. If pressure buildup occurs in the non-selected manifold due to residual liquid in the associated cylinders, the system is reconfigured to dispense the residual liquid.

    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.
