    Abstract: The invention relates to refining and separating a krypton-xenon concentrate. The inventive method consists in dividing said krypton-xenon concentrate into krypton and xenon fractions in a pre-separation column, in addition removing semi-volatile impurities from each fraction, obtaining production krypton and xenon from said refined fractions in krypton and xenon columns and in addition extracting krypton from stripping gas of the krypton column by the rectification thereof. Reflux is formed in condensers-evaporators of the rectification columns in such a way that the formation of a solid phase is excluded . The operation of the rectification columns is initiated by supplying krypton to a contacting space. The inventive device for carrying out said method is also disclosed. Said invention makes it possible to increase the economical efficiency of the production of pure krypton and xenon by means of the maximum extraction thereof from an initial mixture.

    Abstract: A method and backup system for backing up a supply oxygen in an air separation plant in which during normal operation, a stream of oxygen-rich liquid is pumped through a main flow path, extending from a surge tank to a heat exchanger, to deliver an oxygen product. The surge tank receives the oxygen-rich liquid from a bottom region of the lower pressure column of the plant. Additionally, during normal operations, a stream of the oxygen-rich liquid is also introduced to a reserve storage tank through a backup flow path. During a transient operation, where the air separation plant has ceased operation, the surge tank is isolated and liquid is pumped from the surge tank through an auxiliary flow path to an auxiliary vaporizer to continue the supply of the oxygen product and the surge tank is replenished with oxygen-rich liquid previously stored in the reserve storage tank.

    Abstract: A condenser reboiler system located within a bottom region of a low pressure column of a double column arrangement that is used in an air separation system to separate air. The condenser reboiler system incorporates first and second heat exchangers of the down-flow type that are situated in a side-by-side relationship and with the first heat exchanger being shorter than the second heat exchanger so that the first heat exchanger will remain functional after a shut-down of the air separation system when the second heat exchanger (s) are not capable of operating due to liquid dumping into a sump region of the low pressure column. The side-by-side relationship allows the column to be fabricated without excessive height.
