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of a feedstock (F), in which when a fluid/effluent (feedstock F, desorbent D, extract E, raffinate R) is injected/withdrawn into/from a chosen plate (Pi) using an external bypass line (Li−1/i, Li/i+1) connected to said chosen plate (Pi), the flow rate within the said external bypass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(Li−1/i, Li/i+1) is controlled in such a way that: a major proportion of the fluid/effluent (F, D, E, R) is injected/withdrawn into/from the chosen plate (Pi); and a minor proportion of the fluid/effluent (F, D, E, R) is injected/withdrawn into/from the adjacent plate (Pi−1, Pi+1) connected to the said external bypass line (Li−1/i, Li/i+1).
