PROCESS FOR PRODUCING PARAXYLENE COMPRISING TWO SIMUL MOBILE BED SEPARATION UNITS AND TWO ISOMERIZING UNITS, ONE OF WHICH IS GAS PHASE

摘要

The present invention describes a process for the production of high-purity paraxylene from a xylenes cut containing xylenes and ethylbenzene, a process using two simulated moving bed separation units and two isomerization units.
