Abstract

468,872. Obtaining krypton and nitrogen. JACKSON, L. MELLERSH-. (Soc. L'Air Liquide, Soc. Anon. pour L'Etude et l'Exploitation des Precedes G. Claude) May 11,'1936, No. 13298. [Class 8 (ii)] Nitrogen and krypton are obtained simultaneously from air by liquefaction and rectification including washing with liquid nitrogen, introduced at the top of the low-pressure column by a pipe E, the liquid mixture of oxygen and nitrogen into which this nitrogen is converted in the operation is caused to wash a quantity of air greater than this liquid mixture, for the extraction of krypton. For this purpose, supplementary air is introduced by a pipe I into an enlarged part B<1> of the upper column and the excess air from which the krypton has been extracted is removed by a pipe K. In modifications, a single stage rectifier may be used, or a column comprising an enlarged base B<1> through which excess air is passed surmounted by vertical tubes in which condensation with production at the top of liquid nitrogen takes place, these tubes being cooled by the liquid mixture of nitrogen and oxygen collecting in the base.
