Abstract
The present invention relates to a process for producing high purity xenon safely at a high yield from liquid oxygen in a main condenser of an air separating unit. The present invention involves a process for concentrating and recovering xenon by gasifying and introducing liquid oxygen led out from the main condenser in the air separating unit into an adsorption column field with an adsorbent which adsorbs xenon for adsorption and desorption, and a process for rectifying and recovering xenon by introducing concentrated xenon gas into a solid-gas separating column, which is cooled to a temperature at which xenon is solidified but components other than xenon such as oxygen and krypton in the concentrated xenon gas are not solidified to, catch xenon by condensation, then heating the solid-gas separating column after evacuating gas components remained therein.
