Abstract: The disclosure describes refinery processes and process units for suppressing the precipitation and deposition of heavy polynuclear aromatic (HPNA) compounds in a process unit of a refinery, by combining the effluent from a hydrocracking unit with an aromatic solvent stream. Certain costly HPNA treatment processes can be eliminated, downtime can be reduced, and overall distillate yield can be increased by suppressing HPNA precipitation. The aromatic bottoms—which are suitable solvents for this purpose—of an aromatic recovery complex can be used in certain embodiments to dissolve HPNAs and suppress HPNA precipitation.

Abstract: 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.
