    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： Dans un procédé de séparation d'air dans une installation comprenant au moins deux colonnes (1,3), une partie de l'air (100) à une pression intermédiaire se refroidit dans au moins un passage d'un système d'échange thermique qui est régénéré (sont régénérés) par un gaz de l'installation (17,21) qui peut contenir au moins 50 % d'oxygène.
    Le reste de l'air à la moyenne pression (200) est soit épuré en dehors de système d'échange thermique soit envoyé dans un passage qui est épuré de la même manière.

    摘要： An apparatus and method for recovering one or more components from the vapor feed in which the component is recovered from the vapor feed at a lower pressure within a lower pressure cold trap. Thereafter, a higher pressure cold trap is connected to the lower pressure cold trap and the component revaporizes in the lower pressure cold trap and resolidifies in the higher pressure cold trap. The higher pressure cold trap is then isolated and the component is allowed to thaw to build up a vapor pressure such that the component can be delivered for recovery at a high pressure. Two or more components having higher and lower boiling points can be recovered by low pressure cold traps set in series. Low pressure cold traps can be provided to operate in an out of phase relationship so that components are frozen on one set of lower pressure cold traps while being vaporized from the other set of cold traps. In the case of two component recovery, two high pressure cold traps are provided to allow two components to vaporize and thus develop a sufficient vapor pressure to be delivered at the requisite delivery pressure.
