Abstract
In a method comprising an isobaric production phase, a co-current depressurization phase, optionally carried out in a plurality of stages, a counter-current elution phase and a counter-current repressurization phase, optionally carried out in a plurality of stages, the successive balancing phases between two adsorption columns 1, 2, 3, 4 are carried out by passage in an auxiliary column 46, 70 with flow in opposite directions of the gaseous currents corresponding to two successive balancings.
