Integrated processes and systems for producing para-xylenes

An integrated process for producing para-xylenes, the process comprising:

• catalytically reforming a naphtha feed stream to form a reformate stream;
• separating the reformate stream into a C1-C7 hydrocarbon stream and a C8+ hydrocarbon stream;
• exposing the C1-C7 hydrocarbon stream to a first solvent in a solvent extraction unit to form a non-aromatic hydrocarbon stream and a C6-C7 aromatics stream;
• separating the C6-C7 aromatics stream into at least a toluene feed stream;
• separating the C8+ hydrocarbon stream into a C9+ hydrocarbon stream and a xylene stream comprising ortho-xylene, meta-xylene, and para-xylene;
• separating the xylene stream in a p-xylene separation unit to form the para-xylene stream and a xylene isomer stream comprising ortho-xylene and meta-xylene;
• isomerizing the xylene isomer stream with a isomerization catalyst to produce a para-xylene rich stream;
• and
• upgrading the toluene feed stream and the C9+ hydrocarbon stream in a hybrid dealkylation/transalkylation unit with a hydrogen stream and a hybrid transalkylation/dealkylation catalyst to produce a product stream comprising para-xylenes, wherein a ratio by weight of the toluene feed stream to the C9+ hydrocarbon stream is from 0.3 to 3.
