Abstract

432,644. Obtaining krypton and xenon. SOC. L'AIR LIQUIDE, SOC. ANON. POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES G. CLAUDE, 75, Quai d'Orsay, Paris. Jan. 31, 1934, No. 3267. Convention date, Feb. 9, 1933. [Class 8 (ii)] Krypton and xenon are obtained from atmospheric air by rectifying air cooled to near its liquefaction point by washing liquid in amount sufficient to condense practically all the krypton and xenon, but less than sufficient to condense the maximum amount of oxygen ; the washing liquid may be about 10 per cent of the air treated. Air passed alternately through regenerators A<1>, A<2> and expanded in a turbine B is delivered at the bottom of a rectifier C. A part of the vapour evolved at the top of the column passes through exchangers G, F to a compressor E and back through the exchanger F. Part of this vapour is expanded in a motor H and delivered to the heating coil I of the rectifying column and thence to the top as washing liquid. Part of the remainder is liquefied in passing through the exchanger G and forms further washing liquid. The remainder passes to the heating coil of a column K which receives and partly vaporizes the residual liquid in the rectifier. The residual liquid in the column K is drawn off rich in krypton &c., which are extracted therefrom. The vapours may return to the rectifier C or a part may be drawn off as oxygen.
