Abstract

PURPOSE: To recover high-purity Ar gas in high recovery, by carrying out the adsorption and desorption of N2 gas from Ar gas containing N2 using zeolite as the adsorbent under specific condition.
CONSTITUTION: Ar gas containing N2 is introduced into the adsorption column packed with zeolite, and N2 is selectively adsorbed at -70W0°C. The flow of the Ar gas is stopped just before the N2-adsorbed zone reaches the outlet of the adsorption column. The column is heated and the gas existing in the column is expelled from the column. Thereafter, the desorption of N2 is carried out under reduced pressure at -50W+20°C to regenerate the zeolite.
