Title
(EN) PROCESSES AND SYSTEMS FOR PRODUCING ONE OR MORE OF BENZENE, TOLUENE, OR MIXED XYLENES
(FR) PROCÉDÉS ET SYSTÈMES DE PRODUCTION D'UN OU DE PLUSIEURS COMPOSÉS PARMI LE BENZÈNE, LE TOLUÈNE OU DES XYLÈNES MIXTES
Abstract
(EN) A process for producing one or more of benzene, toluene, or mixed xylenes may include combining one or more aromatic feed chemicals, one or more aromatic-based polymers, hydrodearylation catalyst, and hydrogen in a hydrodearylation unit to form a chemical product. The process may also include passing the chemical product out of the hydrodearylation unit, where the chemical product comprises one or more of benzene, toluene, and mixed xylenes. Additionally, a system for producing one or more of benzene, toluene, or mixed xylenes may include a mixing unit and a hydrodearylation unit. An aromatic feed stream and an aromatic-based polymer stream may be in fluid communication with a mixing unit. A mixing unit effluent stream may be in fluid communication between the mixing unit and the hydrodearylation unit. A chemical product stream may be in fluid communication with the hydrodearylation unit.
(FR) L'invention concerne un procédé de production d'un ou de plusieurs composés parmi le benzène, le toluène et des xylènes mixtes pouvant comprendre la combinaison d'un ou de plusieurs produits chimiques aromatiques alimentés, d'un ou plusieurs polymères à base aromatique, d'un catalyseur d'hydrodésarylation et d'hydrogène dans une unité d'hydrodésarylation pour former un produit chimique. Le procédé peut également comprendre le passage du produit chimique hors de l'unité d'hydrodésarylation, le produit chimique comprenant un ou plusieurs composés parmi le benzène, le toluène et des xylènes mixtes. De plus, un système de production d'un ou plusieurs composés parmi le benzène, le toluène et des xylènes mixtes peut comprendre une unité de mélange et une unité d'hydrodésarylation. Un flux aromatique alimenté et un flux de polymère à base aromatique peuvent être en communication fluidique avec une unité de mélange. Un flux d'effluent de l'unité de mélange peut être en communication fluidique entre l'unité de mélange et l'unité d'hydrodésarylation. Un flux de produit chimique peut être en communication fluidique avec l'unité d'hydrodésarylation.
