摘要： A gas stream containing condensable vapours flows through whichever of condenser 16 and 22 is on line. The condensable vapours are condensed therein. A resultant cold, vapour-free, gas stream flows through an economising heat exchanger 18 and is warmed by its passage therethrough. Condensation of the vapour and warming of the cold gas stream is effected by a recirculating refrigerant stream. The refrigerant stream flows through the on-line condenser and is thereby heated. One part of the heated refrigerant stream flows through valve 50 and is employed to warm the cold gas stream in the heat exchanger 18 and is thereby recooled. Liquid cryogen is introduced into the recooled refrigerant stream by means of an ejector 58 which communicates with the on-line condenser to complete the circuit. A second part of the heated refrigerant stream may be vented through valve 52. A third part of the heated refrigerant stream may be employed to defrost the off-line condenser and downstream thereof be introduced into the recooled refrigerant stream.

摘要： A method and apparatus for cooling a heat load in which a pressure vessel (16) is provided to contain a cryogen as a saturated liquid (18) and saturated vapour (20) separated by liquid-vapour interface (22). The pressure vessel (16) has an inlet (24) adapted to receive a subcooled liquid cryogen and thereby convert it to a saturated liquid (18) through contact with the saturated vapour (20). A heated overflow tube (26) projects into the pressure vessel (16) and is level, at one end, with the liquid-vapour interface (22) so that any increase in the saturated liquid overflows into overflow tube (26) and is vaporised to form the saturated vapour (20). The heat transfer and the re-introduction of the vaporised liquid can be effected through forced circulation provided by an ejector (32 or 34). Preferably the pressure vessel (16) is provided with two outlets (28,30) for discharging the saturated cryogen as saturated liquid or vapour. One or more ejectors (32 or 34) having high pressure inlet(s) (42 or 46) in communication with the two outlets (28,30) of the pressure vessel (16) are provided for drawing the heat transfer fluid, after having cooled the heat load, into a heat transfer relationship with the overflowed saturated liquid and then into mixture(s) with the saturated liquid or saturated vapour, or both and for discharging the same out of a high pressure outlet of the ejector to the heat load.

摘要： A cryogen delivery apparatus 1 for delivering cryogen in a saturated state includes a vessel 10 which contains the cryogen in liquid and vapour phases. The vessel 10 has a headspace region 12 and a heat exchanger 22 located within the headspace region 12 for indirectly exchanging heat between the vapour located within the headspace region and a liquid stream composed of the liquid phase of the cryogen. If the cryogen is introduced into the vessel 10 as a subcooled liquid through an inlet 46, the subcooled liquid flows through a withdrawal tube 38 to the heat exchanger 22 and is warmed by passage therethrough and thereby converted into a saturated liquid. The saturated liquid is discharged from a liquid outlet 40 connected to the heat exchanger 22. In the event the liquid enters the vessel as two-phase flow, the vessel 10 acts as a phase separator. A branched supply line 44 is provided having a liquid inlet branch 46 connected to the bottom liquid inlet 46 of the vessel 10 so that a supply stream composed of the cryogen flows into the vessel 10. A vapour inlet branch 48 of the supply line 44 is connected to an inlet 20 to the headspace 12. A heating element 50 is provided to heat the vapour inlet branch 48 so that liquid cryogen is vaporised to replenish vapour within the headspace that is depleted through condensation on the external surfaces of the heat exchanger 22 or discharge from a vapour discharge outlet 18 of the vessel 10.

摘要： In order to store and dispense a liquid mixture containing oxygen so that the liquid will not contain any more than a predetermined concentration of the oxygen at a predetermined pressure, the mixture is introduced into a container at a specified initial concentration. A calculated volume of the saturated state of the liquid having the initial concentration is computed such that, when expanded into the total volume of the container, the resulting liquid would have the maximum enrichment. The liquid is dispensed from a bottom region of the container and dispensing is prevented when the liquid remaining within the container could possibly have the maximum enrichment computed at a particular dispensing pressure. Pressure relief methods are employed to avoid the venting of head space vapour.

摘要： An apparatus 1 for storing a multi-component cryogenic liquid such as 'liquid air' includes a storage tank 10. Headspace vapour 14 flows to an external condensation tank 26 and is condensed therein through indirect heat exchange with liquid being vented from the storage tank 10. The resulting condensate can then be re-introduced into the storage tank through a pressure building circuit 30 applied to the external condensation tank 26. In such manner, the pressure within the storage tank 10 is regulated and the composition of the liquid stored within the storage tank is held constant with some degree of consistency. The use of an external condensation tank allows prior art cryogenic storage tanks and dewars to be retrofitted to store a multi-component cryogenic liquid.
