Abstract

500,544. Separating gases by liquefaction, LEVIN, I. H. July 7, 1937, No. 18866. [Class 8 (ii)] Air is compressed by a pump 2, passed through driers 3, and divided with two streams; one of these passes without further compression successively through heat exchangers 6, 22 and is delivered to the lower column 15 of a rectifier ; the other part is further compressed in a compressor 7, freed from oil in a vessel 8 containing activated alumina, and divided into two streams, one of which is cooled by an external refrigerating circuit 11 and expanded in an engine 14 before passing into the rectifying column, while the other is cooled in an exchanger 25 by a part of the separated gaseous nitrogen and oxygen before entering the column. Part of these gases escaping through branches 27, 20 also cools the exchangers 6, 22 and is warmed to room temperature thereby.
