Abstract: Method for the simulated moving bed (SMB) separation of a feedstock (F), in which: at least one zone (1, 2, 3, 4) contains fewer than three beds, if the stream (D, E, F, R) delimiting said zone and situated upstream of said zone is injected or withdrawn at the plate Pi via the bypass line Li/i+1, then the stream delimiting said zone and situated downstream of said zone is injected/withdrawn at the plate Pj via the bypass line Lj/j+1, and if the stream delimiting said zone and situated downstream of said zone is injected or withdrawn at the plate Pi via the bypass line Li−1/i, then the stream delimiting said zone and situated upstream of said zone is injected/withdrawn at the plate Pj via the bypass line Lj−1/j.

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.

Abstract: Method for the simulated moving bed separation of a feedstock (F), in which when a fluid/effluent (feedstock F, desorbent D, extract E, raffinate R) is injected/withdrawn into/from a chosen plate (Pi) using an external bypass line (Li−1/i, Li+1/i) connected to said chosen plate (Pi), the flow rate within the said external bypass line (Li−1/i, Li+1/i) is controlled in such a way that: a major proportion of the fluid/effluent (F, D, E, R) is injected/withdrawn into/from the chosen plate (Pi); and a minor proportion of the fluid/effluent (F, D, E, R) is injected/withdrawn into/from the adjacent plate (Pi−1, Pi+1) connected to the said external bypass line (Li−1/i, Li+1/i).
