Abstract:
The present invention describes a novel configuration for simulated counter-current para-xylene production units, constituted by two adsorbers, characterized in that the volume occupied by the solid adsorbent is reduced by at least 8% compared with the volume of solid adsorbent contained in the adsorbers of a prior art unit. This novel configuration can be used to minimize the quantity of solid adsorbent necessary to produce a given quantity of para-xylene.
