Abstract

A device and process for injecting a diverted fluid into a simulated moving bed comprises a vessel containing beds of adsorbant Ai separated by plates Pi for distributing and extracting fluids, each plate comprising at least one pannel, each pannel comprising a single chamber Ci for distributing, mixing and/or extracting fluid, and a bypass circuit placing a plate in communication with a bypass line (Li, j). The device also comprises means (14, Voi,j, 20) for bringing at least one chamber (Ci) into communication with at least one bypass line (Li, j); one end of the bypass line is connected with said chamber Ci of a pannel of plate Pi and the other end communicates with a region (Ri+1) of a pannel of the distributor plate Pi+1, said region being distinct from the distribution chamber Ci+1.Application to separating n-paraffins containing 10 to 13 carbon atoms from sweetened kerosene type feeds.
