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than three beds, if the stream (D, E, F, R) delimiting said zone and situated upstream of said zone is injected or withdrawn at the plate Pi via the bypass line Li/i+1, then the stream delimiting said zone and situated downstream of said zone is injected/withdrawn at the plate Pj via the bypass line Lj/j+1, and if the stream delimiting said zone and situated downstream of said zone is injected or withdrawn at the plate Pi via the bypass line Li−1/i, then the stream delimiting said zone and situated upstream of said zone is injected/withdrawn at the plate Pj via the bypass line Lj−1/j.
