    Abstract: The invention relates to a method for purifying a mixture to be separated, in a multicolumn chromatography system, the method comprising successively and cyclically:



    a step of collecting a raffinate, a step of injecting the mixture to be separated, a step of collecting an extract and an eluent injection step, at an operating temperature;
    wherein the mixture to be separated has a viscosity at 20° C. greater than or equal to 3 mPa·s; and wherein the dry matter mass concentration of the mixture to be separated is equal, within 5%, to a threshold concentration, said threshold concentration is such that:
    the viscosity of the mixture to be treated at a dry matter mass concentration equal to the threshold concentration and at the operating temperature, is equal to twice the viscosity of the mixture to be treated, at a dry matter mass concentration equal to 85% of the threshold concentration and at the operating temperature.

    Abstract: Methods and systems for separating para-xylene are disclosed. In one exemplary embodiment, a method for separating para-xylene includes the steps of providing a feed stream including para-xylene and other C8 aromatic hydrocarbons to a first adsorbent bed within a radial flow simulated moving bed chamber and providing a desorbent stream to a second bed within the radial flow simulated moving bed chamber. The method further includes circulating the feed stream and the desorbent stream radially within the radial flow simulated moving bed chamber to third and fourth beds within the radial flow simulated moving bed chamber. Still further, the method includes withdrawing an extract stream including the para-xylene from the third bed and withdrawing a raffinate stream including the other C8 aromatic hydrocarbons from the fourth bed.
