Abstract

In a first step of the method, the gas mixture to be treated is injected into a column swept by a continuous stream of carrier gas and containing a suitable selective solid adsorbent until saturation of this latter by the adsorbed constituent of the gas mixture. In a second step, small quantities of the mixture to be treated and representing a fraction of the quantity injected into the column during the first step are injected periodically so as to collect successively at the column outlet a fraction which is enriched in the non-adsorbed constituent and a fraction which is purified in the adsorbed constituent.
