  • Patent number: 10767923
    Abstract: Device and method for purifying a gas mixture to produce a concentrated gas, notably neon, starting from a mixture comprising neon, said device including, in a cold box housing a cryogenic purification circuit comprising, in series, at least one unit for purifying the mixture by cryogenic adsorption at a temperature between 65K and 100K and notably 65K, then a unit for cooling the mixture to a temperature between 25 and 65 K and then a unit for cryogenic distillation of the mixture to produce the concentrated liquid at the outlet of the cryogenic distillation unit, characterized in that the unit for cooling the mixture to a temperature between 25 and 65 K comprises at least one cryocooler that extracts thermal power from the mixture via a heat exchanger.

  • Publication number: 20150362128
    Abstract: Device for supplying fluid comprising a source tank for storing gaseous fuel at a cryogenic temperature in the form of a liquid-gas mixture, a cryogenic pump, the pump comprising a suction inlet connected to the lower part of the tank via a suction line, a high-pressure first outlet intended to supply high-pressure fluid to a user and a degassing second outlet connected to the upper part of the tank via a return pipe, the device being characterized in that it comprises a cryogenic buffer storage volume, a first pipe connecting the lower part of the buffer storage volume to the tank and a second pipe connecting the upper part of the tank to the buffer storage volume, and in that the device comprises a liquefaction member for liquefying the gas in the buffer storage volume.
