Abstract

184,787. Soc. l'Air Liquide, Soc. Anon. pour l'Etude et l'Exploitation des ProcÚdÚs G. Claude. Aug. 13, 1921, [Convention date]. Separating gaseous mixtures by liquefaction and solidification.-In the purification or drying of air or gases by cooling in heat-exchange apparatus, rime or solid deposit formed on the walls of the tubes is detached by temporarily reversing the direction or flow of the air or gas to be cooled so that the incoming warm air &c. meets first the parts of the tubes coated with rime &c. The detached rime falls by gravity, or is blown by the current of air &c., to a chamber at the end of the tubes, where it is melted after normal working has been resumed, and serves to cool the incoming air. The invention is applicable to the cooling of compressed air by nitrogen in air-liquefying processes, or to the separation of helium from gases by freezing out solidifiable constituents. The apparatus comprises a nest of tapered tubes A in a casing B fitted with baffles C, nitrogen or other cooling-medium being circulated around the tubes from an inlet E to an outlet F. A multiple-way inlet and outlet cock I arranged at the top of the apparatus is set in normal working so that the air &c. to be cooled enters through a passage 0, and passes through a port T, passage O2 and pipe P to the bottom of the tubes, and leaves the apparatus through a central port V and passage O3. For detaching the rime &c. the valve is set so that the gas to be cooled enters the tubes at the top by the central port and leaves at the bottom by the pipe P. The taper of the tubes facilitates the release of the rime &c., which collects on a grating R and is melted by the incoming air when the normal flow is resumed.
