ARGON PURIFICATION USING TEMPERATURE SWING ADSORPTION: LIQUID ARGON PASSED THROUGH ADSORPTION BED AT TEMPERATURE BETWEEN THE BUBBLE POINT AND DEW POINT

摘要

High purity argon is produced by subjecting a two-phase liquid-vapour mixture containing up to 3 volume % of nitrogen and/or up to 5 volume % oxygen to cryogenic temperature swing adsorption in an adsorption bed containing one or more adsorbents selective for nitrogen and/or oxygen at a temperature between the bubble point and the dew point of the two-phase mixture.
