摘要: Air is separated in a cryogenic distillation system operating a dual reboiler/condenser cycle. Refrigeration for the system is usually provided by expanding a process stream. In the present invention, refrigeration is provided by introducing from an external source at least one refrigerant.

摘要: A storage vessel comprises a condenser for condensing boil-off vapor by direct heat exchange with cryogenic liquid feed to the vessel. The condenser comprises a packed arrangement of vapor-liquid contact packing that comprises a top end portion and a bottom end portion. At least said top end portion is open to the vapor space to allow entry of boil-off vapor into the arrangement. The bottom end portion is in fluid flow communication with the lower portion of the storage vessel. One advantage of the invention is that the condenser is open to the vapor space of the storage vessel thereby allowing boil-off vapor to be drawn into the condenser by the condensation action of the vapor.
