Abstract	The aim of this work was to evaluate the role of desorbent selectivity variation on the tuning and the performance of a SMB process. For this purpose a separation regions study in the case of a four-zones non-linear transfer limited SMB was carried out. The SMB unit was modelled considering the equivalent True Moving Bed (TMB). A set of 11 desorbents with different strength was considered: 3 desorbents with constant strength and 8 desorbents with variable strength. For each system, the optimal operating conditions are determined using the separation regions approach, with plots in both (Q2, QF) and (Q4, QD) planes. Depending on the separation considered, a variable selectivity desorbent can lead to an improvement or can be detrimental to process performances. A careful choice of desorbent selectivity (either constant or variable) is then crucial to achieve maximal process performance.
