Abstract
An integrated process for conversion of a hydrocarbon stream comprising at least 60% by weight C5-C6 normal paraffins and iso-paraffins to enhanced value aromatics. The process includes passing the hydrocarbon stream through the first reactor, the first reactor being an aromatization reactor with an aromatization catalyst disposed therein to generate an aromatization product stream. The process further includes passing the aromatization product stream through a separator configured to remove C1-C4 gases to generate an aromatic rich stream. The process finally includes passing the aromatic rich stream combined with a reformate effluent fraction from a catalytic reforming unit to an aromatic recovery complex to separate the aromatic rich stream into a benzene fraction, a toluene fraction, a para-xylene fraction, an aromatic bottoms fraction comprising C9+ aromatic hydrocarbons, and a non-aromatics fraction. An associated system for performing the process is also provided.
