  • Patent number: 9261295
    Abstract: Embodiments of the disclosed invention relate to providing cooling to instruments or other components. More particularly, hydrogen from a store is provided to pre-cool helium contained within a closed loop refrigeration circuit. Helium pre-cooled by the hydrogen, for example after expansion of the hydrogen in an expansion valve, is itself passed through an expansion valve, and applied to a heat load. The helium can be circulated through the refrigeration circuit using a compressor. The hydrogen used for pre-cooling the helium can be from a store of hydrogen that also provides fuel to a hydrogen consumer, for example for propulsion of a vehicle carrying the cooling system or for the production of electrical power. A hydrogen consumer can also be provided with hydrogen that has first been used to pre-cool the helium refrigeration circuit.

  • Patent number: 7841190
    Abstract: Methods and devices for the management of cryogenic agents within analytical systems using freeze thaw valving having an expansion chamber that limits the flow of the cryogenic agent. The expansion chamber is fitted with an expansion nozzle through which a cryogen flows and a porous frit that allows the cryogen to be exhausted. The porous frit initially allows a rapid flow of cryogen into the expansion chamber. This rapid flow lowers the temperature of the expansion chamber causing fluid contents within a freeze thaw segment to freeze. As the cryogen expands into the expansion chamber and turns into a solid, the porous frit is occluded causing the rapid flow to be restricted. The restriction of the cryogen flow by the occlusion of the porous frit allows the freeze thaw valve to use significantly less cryogen. Sublimation of the cryogen trapped within the porous frit provides sufficient cooling to maintain the valve in its closed position.

  • Patent number: 7013673
    Abstract: Processes and apparatus are disclosed for separating and purifying aqueous solutions such as seawater by causing a substantially impermeable mat of gas hydrate to form on a porous restraint. Once the mat of gas hydrate has formed on the porous restraint, the portion of the mat of gas hydrate adjacent to the restraint is caused to dissociate and flow through the restraint, e.g., by lowering the pressure in a collection region on the opposite side of the restraint. The purified or desalinated water may then be recovered from the collection region. The process may be used for marine desalination as well as for drying wet gas and hydrocarbon solutions. If conditions in the solution are not conductive to forming hydrate, a heated or refrigerated porous restraint may be used to create hydrate-forming conditions near the restraint, thereby causing gas hydrates to form directly on the surface of the restraint.

  • Patent number: 6079213
    Abstract: Methods of collecting, thawing, and extending the useful polarized life of frozen polarized gases include heating a portion of the flow path and/or directly liquefying the frozen gas during thawing. A polarized noble gas product with an extended polarized life product is also included. Associated apparatus such as an accumulator and heating jacket for collecting, storing, and transporting polarized noble gases include a secondary flow channel which provides heat to a portion of the collection path during accumulation and during thawing.

  • Patent number: 6079222
    Abstract: The object of the invention is to provide a method for preparing deep-frozen liquid gas for the purpose of recovering process energy for a downstream process, with which the refrigerating capacity of the deep-frozen liquid gas can also be used in the downstream process. According to the invention, this is achieved by the fact that the refrigerating capacity of the deep-frozen liquid gas (1) is fed as a heat sink to at least one of the part-steps of the downstream process via at least one heat-exchange medium (28, 54, 79) and, if said heat-exchange medium (28, 54, 79) is not available, the deep-frozen liquid gas (1) is regasified with an additional heat-exchange medium (32).

  • Patent number: 6003332
    Abstract: A process and system for producing pellets of high density carbon dioxide or other gases utilize a chamber containing a plurality of cell-like freezing compartments within which ice is to be formed. A gas desired to be frozen into ice is introduced into the chamber while the internal pressure of the chamber is maintained at a level which is below the equilibrium triple pressure of the gas. The temperature of the freezing compartments is lowered to a temperature which is below the equilibrium vapor pressure temperature of the gas at the chamber pressure so that the gas condenses into ice within the compartments. The temperature of the freezing compartments is thereafter raised so that the ice is thereby released from and falls out of the compartments as pellets for collection.

  • Patent number: 5724831
    Abstract: For cooling food products in a container, a distributor pipe for supplying liquid carbon dioxide extends into an interior of the container and a plurality of nozzles are arranged on the distributor pipe so that liquid carbon dioxide is discharged from the nozzles in jets extending substantially parallel to a longitudinal axis of the distributor pipe and against one another to collide at the midpoint between two neighboring nozzles.

  • Patent number: 5644923
    Abstract: A system for filtering contaminants from a gas stream through atomized ultrafreezing including: a housing having an inlet mouth and an outlet mouth; a fluid temperature regulating element disposed within the inlet mouth; a venturi-type valve having a fluid speed regulator disposed downstream of the temperature regulating element; a down pipe disposed downstream of the venturi-type valve; at least one atomized water injector at the inlet of the down pipe which is capable of spraying the contaminated gas stream exiting the venturi-type valve; at least one liquid nitrogen shower element disposed in the down pipe downstream of the water injector which is capable of freezing the water, wherein water containing the contaminant is capable of solidifying into hail and precipitating; and a decanter connected to the outlet of the down pipe having a first separator for removing the hail from the gas stream, a discharge valve at the bottom of the decanter for discharging the hail from the decanter, and a second separator
