Abstract
A simulated moving-bed (SMB) pilot plant, characterized by two unique features, the number of ports (6 instead of 24, as in most industrial applications) and the fluid phase (vapor iather than liquid), has been built and operated. Such a plant has proven capable to achieve complete separation for a mixture of m- and p-xylene using isopropylbenzene as desorbent and KY zeolites as adsorbent. The dynamic behavior of the unit has been investigated and compared with model predictions, both in terms of approach to cyclic steady state as well as of responses to typical inputs. The role of the key design parameters on the steady-state separation performance of the unit has been analyzed cxperimentally. demonstrating the consistency with the predictions of the Equilibrium Theory.Keywords
