SELF-CONTAINED SMALL-SIZED STATION FOR RECOVERY OF XENON FROM WASTE GAS- NARCOTIC MIXTURES Russian patent published in 2002 - IPC

FIELD: production of pure (98.0-99.0+ACU-) inert gases, in particular, of expensive and difficulty available xenon from waste gas-narcotic mixtures of narcosis apparatuses with minimized loss of it. SUBSTANCE: the station has a desorber with a heat-insulated body and 2-10 internal removable cartridges filled with sorbent and connected through cryopumps, made circulating with two or more cylinders suspended from dynamometers and placed in a heat-insulated cooling chamber. The station is provided with a source of gas-carrier installed before the desorber, apparatus for absorption of CO₂ and apparatus for extraction of H₂O, positioned after the desorber, as well as with a vacuum-station positioned after the cryopump. EFFECT: enhanced capacity, production of xenon of a high degree of purity, reduced power consumption and improved control of the desorption process, simplified and reduced cost of transportation of recovered xenon, three is no need in complex equipment, enhanced efficiency of the cryopump and service life of the cartridges. 2 cl, 1 dwg
