Abstract

797,647. Cold separation of gas mixtures. NAAMLOOZE VENNOOTSCHAP PHILIPS, GLOEILAMPENFABRIEKEN. Nov. 2, 1956 [Nov. 5, 1955], No. 33521/56. Class 8(2). Separation of readily condensible constituents, e.g., water vapour and carbon dioxide from a gas mixture, e.g., air is effected in a heat exchanger duct having an inlet 5, pure gas outlet 6 and a plurality of baffles, e.g., pins 2 projecting from a common supporting plate 1 in thermal contact with a source of cold 7 ; the mean temperature difference between adjacent pins or adjacent groups of pins in the direction of gas flow being not more than 20‹C. and the thermal resistance of the pins being such that their free ends 10 one at least 5‹C. warmer than the ends 11 secured to the plate 1. In a modification water ice collects on pins in a slightly inclined portion of the duct whereas carbon dioxide ice collects on pins in a vertical position. In a further modification the baffles comprise slotted plates projecting upwardly from the support plate the underside of which bounds a duct traversed by cold gaseous nitrogen from an air rectification column.
