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.
