A para-xylene recovery process including adsorption apparatus containing a para-selective adsorbent to separate para-xylene and ethylbenzene from a C8 aromatic hydrocarbon stream, said process operated isothermally in the vapor phase at elevated temperatures and pressures, and continuously controlled in real-time by analysis of an effluent stream using NIR spectroscopy.
L'invention concerne un procédé de récupération de para-xylène utilisant un dispositif d'adsorption contenant un adsorbant para-sélectif en vue de séparer le para-xylène et l'éthylbenzène à partir d'un flux d'hydrocarbures aromatiques C¿8?, ledit procédé étant réalisé de manière isothermique dans une phase vapeur à des températures et pressions élevées, et régulé de manière continue en temps réel par analyse d'un flux d'effluents au moyen d'une spectroscopie NIR.
