Abstract
An integrated slurry hydroprocessing and steam pyrolosyis process for the production of olefins and aromatic petrochemicals from a crude oil feedstock is provided. Crude oil, a steam pyrolysis residual liquid fraction and slurry reside are combined and treated in a hydroprocessing zone in the presence of hydrogen under conditions effective to produce an effluent having an increased hydrogen content. The effluent is thermally cracked with steam under conditions effective to produce a mixed product stream and steam pyrolysis residual liquid fraction. The mixed product stream is separated and olefins and aromatics are recovered and hydrogen is purified and recycled.
