ABSTRACT:
Process for purifying an inert fluid, in particular argon or helium, with respect to at least one of its impurities nitrogen (N.sub.2), oxygen (O.sub.2), carbon dioxide (CO.sub.2), carbon monoxide (CO) and hydrocarbons, in which at least some of the impurities are removed using a first adsorbent of the X zeolite type having a silica to aluminum ratio less than or equal to 1.15, and a purified inert fluid containing at most 10 ppb, preferably at most 1 ppb of impurities is recovered.
