An integrated process for producing para-xylenes may include catalytically reforming a naphtha feed stream; separating the reformate stream into a C-Chydrocarbon stream and a Chydrocarbon stream; exposing the C-Chydrocarbon stream to a first solvent in a solvent extraction unit to form a non-aromatic hydrocarbon stream and an aromatics stream; upgrading the aromatics stream to form a toluene-rich transalkylation feed stream; separating the Chydrocarbon stream into a Chydrocarbon stream, a para-xylene stream and a xylene isomer stream; dealkylating the Chydrocarbon stream; separating the dealkylation product stream into an additional xylene stream and a tri-methyl benzene rich stream; and upgrading the toluene-rich transalkylation feed stream and the tri-methyl benzene rich stream with a hydrogen stream to produce an alkyl-benzene stream and additional xylene stream, wherein a ratio by weight of the toluene-rich transalkylation feed stream to the tri-methylbenzene rich stream is from 0.3 to 3.
