Title:
ASSEMBLY FOR SEPARATING GAS MIXTURES IN FRACTIONATING COLUMNS
Document Type and Number:
WIPO Patent Application WO/2013/141761
Kind Code:
A3
Abstract:
The invention relates to inert gas production processes and can be used for obtaining a xenon concentrate from a stream of xenon-containing oxygen. According to this method, an initial gas mixture is pre-cooled and fed into a xenon adsorber, from which a xenon concentrate is subsequently recovered, wherein before the mixture is fed into the adsorber, radon is removed therefrom by means of being fed into a cooled sorbent in a radon adsorber, oxygen is periodically substituted in the xenon adsorber by an inert medium by means of ceasing the supply of gas mixture and feeding a substitution gas into the xenon adsorber until a residual oxygen concentration that does not exceed an established threshold is obtained at the outlet of the xenon adsorber, and the concentrate is recovered from the xenon adsorber by means of creating a temperature gradient in the sorbent of the xenon adsorber, from the inlet of the adsorber to the outlet thereof, until a xenon desorption wave is produced at the outlet, whereupon the xenon fraction is withdrawn. The corresponding assembly comprises a xenon adsorber, a heat exchanger, a filling ramp, a radon adsorber, an electric heater, a diaphragm compressor, an ejector, a flow meter, valves and pipelines.
