CRYOGENIC PROCESS FOR THE PRODUCTION OF METHANE-FREE, KRYPTON/XENON PRODUCT

摘要

PATENT 211PUS04362 The present invention relates to a process for the production of kryton and xenon by using a vapor stream containing greater than 2X oxygen to strip a liquid stream containing oxygen, krypton, methane and xenon of methane. This is accomplished by properly adjusting the liquid to vapor flows in the distillation column. The use of a suitable reflux liquid will decrease the loss of krypton and xenon in the methane laden vapor stream leaving the distillation system.
