Processes and systems are disclosed for improving the yield from reforming processes. Aromatic complex bottoms, or a heavy fraction thereof, are subjected hydrogenation to produce additional gasoline and higher-quality aromatic compounds.

Systems and methods include an aromatics complex (ARC), the ARC in fluid communication with a naphtha reforming unit (NREF) and operable to receive a reformate stream produced by the NREF, and the ARC further operable to separate the reformate stream into a gasoline pool stream, an aromatics stream, and an aromatic bottoms stream; and a hydrodearylation unit operable to receive heavy, non-condensed, alkyl-bridged, multi-aromatic compounds from the aromatic bottoms stream, the hydrodearylation unit further operable to hydrogenate and hydrocrack the heavy, non-condensed, alkyl-bridged, multi-aromatic compounds to produce a stream suitable for recycle to the NREF or the reformate stream, where the hydrodearylation unit is further operable to receive hydrogen produced in the NREF.

A naphtha hydrotreating process involves the use of a sulfur guard bed (SGB) with a controlled bypass which allows for control of the sulfur in the feed to a downstream processing unit. The SGB is installed on the light ends stripper bottoms stream in a naphtha hydrotreating unit.

A process for separating and upgrading a hydrocarbon feed includes passing the hydrocarbon feed to a distillation unit to separate it into at least a naphtha stream and a residue, passing the naphtha stream to a NHT that hydrotreats the naphtha stream to produce a hydrotreated naphtha, passing the hydrotreated naphtha to an NREF that reforms the hydrotreated naphtha to produce a reformate, passing the reformate to an ARC that processes the reformate to produce at least one aromatic product effluent and an aromatic bottoms stream, and passing at least a portion of the aromatic bottoms stream comprising C9+ aromatic compounds to a steam cracking unit. The steam cracking unit may further upgrade the aromatic bottoms stream, which may increase the yields of greater value chemical intermediates and fuel blending components from the process. Systems for conducting the process are also described.
