Abstract

746,436. Cold separation of gas mixtures. NAAMLOOZE VENNOOTSCHAP PHILLIP'S GLOEILAMPENFABRIEKEN. April 15, 1954 [April 22, 1953], No. 11161/54. Class 8(2). In the separation of one or more condensible components of a gas mixture e.g., the water and carbon dioxide content of air by cooling in a heat exchanger the latter comprises a plurality of fins or vanes 16, Fig. 1, projecting laterally from a carrier 15 connected at one end 14 to a thermal sink e.g., a known gas refrigerator, the mean temperature of the vane or vanes on which deposition of a component begins being maintained at not more than 20‹C. below the highest temperature at which deposition can occur and also the temperature difference between successive vanes in the direction of gas flow being not greater than 20‹C. In operation air enters an aperture 23 of an insulating screen 22 and traverses staggered apertures 17 of a group 18 of vanes 16 which serve to freeze the water vapour content. Dry air at 60‹C. then traverses a second group 19 of vanes where it is cooled to about -140‹C. without further deposition and finally traverses a group 20 of vanes where carbon dioxide ice is deposited at a temperature of between -140 and -180‹C. The wall thickness and hence the thermal conductance of the carrier 15 varies from zone to zone. The so purified air is liquefied by contact with the base 14 and is discharged through duct 21. In a modification an ice depositing set of apertured vanes 35, Fig. 2, carried by tubes 33, 42 surround non- depositing vanes 37 and carbon-dioxide depositing vanes 35 carried by tubes 32, 31, 39. The tube 33 is insulated from tube 39 but is thermally connected to tube 33 by an apertured disc 34. Air enters through a duct 44, melted ice and liquid air leave through ducts 51, 48 respectively.
