摘要： The invention relates to a method and a device for separating a gas component in a gas mixture by freezing. The gas component to be separated has the lowest vapor pressure when compared with the other gas components in the gas mixture. A working temperature is chosen at which the gas components to be separated freeze out almost completely. The partial pressure of the other gas components at working temperature is kept lower than the vapor temperature of the other gas components at working temperature. Once the components to be separated have been frozen out, the other gases are evacuated. The device comprises at least two cooling tanks. Means are provided to alternately feed the gas mixture to the cooling tanks so that a predetermined partial pressure arises in each tank.

摘要： An apparatus (2, 20, 200) for separating CO2 from a mixture of gases includes CO2 and a second gas, the apparatus (2, 20, 200) includes an active heat exchanger (216) and a regenerating heat exchanger (221). The active heat exchanger (216) includes a heat exchange surface in contact with the mixture of gases. The mixture of gases is present in the active heat exchanger (216) at a predetermined pressure which is chosen such that CO2 freezes on the heat exchange surface when the surface is cooled by a refrigerant having a temperature below that at which CO2 freezes at the predetermined pressure. The regenerating heat exchanger (221) includes a heat exchange surface in contact with the refrigerant and also in contact with a layer of frozen CO2. The refrigerant enters the regenerating heat exchanger (221) at a temperature above that at which the CO2 in the frozen layer of CO2 sublimates. The sublimation of the solid CO2 cools the refrigerant prior to the refrigerant being expanded through an expansion valve (215), which reduces the temperature of the refrigerant to a point below the freezing point of CO2 at the predetermined pressure. The refrigerant is re-compressed by a compressor (60, 160, 218) after leaving the active heat exchanger (216). In the preferred embodiment of the present invention, the gaseous CO2 released by the regenerating heat exchanger (221) is used to precool the incoming gas mixture. A second precooling heat exchanger (167) precools the compressed refrigerant by providing thermal contact with the refrigerant leaving the active heat exchanger (216).

摘要： 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.

摘要： A method of producing solid carbon dioxide comprises the steps of providing a supply of refrigerant (1) which is arranged to flow along a path at least part of which is adjacent to a die (4) so that the refrigerant is in thermal contact with the die (4), providing a supply of liquid carbon dioxide (9) to an inlet at one end of the die (4) and allowing the carbon dioxide to flow into the die (4), and, extruding solid carbon dioxide (16) from an outlet (12) at the other end of the die (4) under the pressure exerted by liquid carbon dioxide at the die inlet. In a preferred embodiment, solid carbon dioxide is formed by directly refrigerating liquid carbon dioxide using liquid nitrogen as refrigerant.

摘要： A method and apparatus for the accumulation of hyperpolarized 129 Xe is described. A gas mixture comprising 129 Xe is flowed through a heat exchanger tube from the first end to the second end. Concurrently, the outer surface of the heat exchanger tube is controllably refrigerated, beginning with the second end, to a temperature low enough to freeze the 129 Xe on the inner surface of the heat exchanger tube.

摘要： Condensable vapors such as carbon dioxide are separated from light gases in a process stream. The systems and methods employ a particle bed cooled by an in-bed heat exchanger to desublimate the condensable vapors from the process stream. The condensable vapors are condensed on the bed particles while the light gases from the process stream, which are not condensed, form a separated light-gas stream. The separated light-gas stream can be used in a recuperative heat exchanger to cool the process stream.
