The industrial separation of p-xylene was considered by means of a standard SMB (Simulated Moving Bed) system as well as the Varicol mode of operation. Both modes of operation were simulated accounting for adsorbent capacity decline using the TMB (True Moving Bed) approach in the case of standard SM...
