PUMPING OF LIQUIFIED GAS

Method and apparatus for supplying from a vessel to a pump liquified gas with subcooling so as to avoid cavitation during pumping. A supply conduit supplies liquified gas from the vessel bottom to a pump sump which envelops the flowpath elements of a pump and the pump suction. A return conduit returns vapor and excess liquified gas from the sump to the bottom of the vessel. Heating means, preferably heat leak into the return conduit, reduces the density of the fluid in the return conduit thereby increasing the rate of liquified gas flow in the supply conduit and reducing its temperature rise enroute to the pump. Further subcooling is secured by locating the intake to the supply conduit remote from a wall of the vessel in a cooler strata of liquid, and the discharge of the return conduit proximate to a wall of the vessel in a warmer strata in the vessel. The low flow friction losses in the supply and return conduits enhance the circulation rate of liquified gas in the conduits, and the short ...

Cryogenic storage vessel

A vessel for storing and transporting cryogenic fluids such as liquid helium. The vessel comprises a plurality of elongated containers supported one within another in coaxial circumjacent relation in a manner minimizing heat transmission therebetween, and it further comprises a cooling system forming a temperature barrier that restricts inward migration of heat from the outer to the inner container. Respecting the support system, the inner fluid-receiving container is supported by an encapsulating intermediate heat shield container which in turn is supported by an outer jacket surrounding and enclosing the intermediate heat shield. The support means effecting such interrelationship includes both transverse support structure constraining the containers relative to each other against transverse or radial displacements and longitudinal support structure interconnecting the containers one with another and constraining the same against relative longitudinal displacements at least at one end of the vessel. The transverse support structure constitutes a plurality of structurally independent supports as respects the interconnection of the inner container with the intermediate heat shield and interconnection of the heat shield with the outer jacket; and all of the support structures define restricted thermal flow paths through which heat migration from the outer container to the inner container is sharply limited. Respecting the cooling system, two flow-separated cooling coils surround the heat shield container, one of which carries a coolant such as liquid nitrogen and the other of which connects both with the inner fluid-receiving container and with a delivery system through which fluid is withdrawn from the inner container.

Cryogenic tank assembly with a pump drive unit disposed within fluid storage vessel

The pump assembly includes a pump, a pump drive unit, and a drive shaft operatively connecting the pump to the pump drive unit. The pump is configured to receive a quantity of the fluid from the cryogen space and deliver it therefrom at a delivery pressure higher than the storage pressure. The pump drive unit is at least partially disposed within the sleeve of the vessel.

Cryogenic storage tank with built-in pump

A cryogenic storage tank with a built-in pump for pumping cryogen directly from the primary storage container consistent with low boil-off losses of cryogen has an outer vessel, an inner vessel and an evacuated insulation space therebetween. A pump mounting tube assembly extends into the interior of the inner vessel and includes an inner pump mounting tube and an outer pump mounting tube joined at their lower rims to define an insulating jacket between the two tubes. The inner pump mounting tube is affixed at its upper end to the outer vessel while the outer pump mounting tube is affixed at its upper end to the inner vessel. The inner pump mounting tube defines a relatively long heat path into the cryogenic container and is itself insulated from the liquid cryogen by a pocket of trapped gas formed within the inner pump mounting tube by heated cryogen. A pump may be introduced through the inner pump mounting tube and is also insulated against contact with liquid cryogen by the trapped gas such that only the lowermost end of the pump is immersed in cryogen thereby minimizing heat leakage into the tank.

Pressure building device for a cryogenic tank

A device for pressurizing a tank containing a supply of cryogenic liquid features a tubular enclosure disposed within the cryogenic liquid. The tubular enclosure features an opening in its bottom and is in communication with a pressure builder coil external to the tank. The vapor side of the pressure builder coil is in communication with the head space of the tank. An electric heater element is disposed in the bottom of the tubular enclosure. An insulating tube may optionally be disposed about the tubular enclosure. In addition, a ball may optionally be positioned adjacent the opening in the tubular enclosure so that a check valve is formed. The device fits through the tops of existing cryogenic tanks.

Storage tank for a cryogenic fluid with a partitioned cryogen space

A cryogenic storage tank comprises a partition that divides a cryogen space into a main storage space and an auxiliary space. A valve disposed inside the cryogen space is associated with a first fluid passage through the partition. The valve comprises a valve member that is actuatable by fluid forces within the cryogen space. A second fluid passage through the partition comprises a restricted flow area that is dimensioned to have a cross-sectional flow area that is smaller than that of a fill conduit such that there is a detectable increase in back-pressure when the main storage space is filled with liquefied gas. A preferred method comprises establishing a vapor-filled ullage space when the main storage space is being vented and re-filled with cryogenic fluid, by draining liquefied gas from the auxiliary space through the first fluid passage under the influence of a vapor pressure differential permitted by the partition. If the vapor pressure differential reverses during re-filling, the valve can close to preserve the vapor-filled ullage volume. Re-filling is stopped when an increase in back pressure is detected during re-filling.
