Abstract
A system includes a hydroprocessing zone configured to remove impurities from crude oil; a first separation unit configured to separate a liquid output from the hydroprocessing zone into a light fraction and a heavy fraction; an aromatic extraction subsystem configured to extract aromatic petrochemicals from the light fraction; and a pyrolysis section configured to crack the heavy fraction into multiple olefinic products.
