Claim Text:
1. An integrated slurry hydroprocessing and steam pyrolysis process for production of olefinic and aromatic petrochemicals from crude oil, the process comprising: a. treating the crude oil and residuals or bottoms derived from slurry residue, and optionally, one or more of a heated stream within the steam pyrolysis zone or a mixed product stream, in a slurry hydroprocessing zone in the presence of hydrogen under conditions effective to produce an effluent having an increased hydrogen content; b. separating the effluent from step (a) into a vapor phase and a liquid phase in a flash vessel having at its inlet a vapor-liquid separation device including c. thermally cracking the effluent in the presence of steam in a steam pyrolysis zone under conditions effective to produce the mixed product stream; d. separating the mixed product stream; e. purifying hydrogen recovered in step (d) and recycling it to step (a); and f. recovering olefins and aromatics from the separated mixed product stream.
