Claim Text:
1. An integrated hydroprocessing, steam pyrolysis and slurry hydroprocessing process for direct conversion of crude oil to produce olefinic and aromatic petrochemicals, the process comprising: a. hydroprocessing the crude oil in the presence of hydrogen under conditions effective to produce a hydroprocessed effluent having a reduced content of contaminants, an increased paraffinicity, reduced Bureau of Mines Correlation Index, and an increased American Petroleum Institute gravity; b. thermally cracking hydroprocessed effluent and a slurry process product in the presence of steam in a steam pyrolysis zone under conditions effective to produce a mixed product stream; c. processing residuals or bottoms derived from one or more of the hydroprocessed effluent, a heated stream within the steam pyrolysis zone, or the mixed product stream, in a slurry hydroprocessing zone to produce the slurry process product; d. separating the mixed product stream; e. purifying hydrogen recovered in step (d) and recycling it to the step of hydroprocessing; and f. recovering olefins and aromatics from at least a portion of the separated mixed product stream.
