Claim Text:
1. An integrated hydrotreating, solvent deasphalting and steam pyrolysis process for the direct processing of a crude oil to produce olefinic and aromatic petrochemicals, the process comprising: a. charging the crude oil to a hydroprocessing zone operating 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. charging the hydroprocessed effluent to a solvent deasphalting zone with an effective amount of solvent to produce a deasphalted and demetalized oil stream and a bottom asphalt phase; c. thermally cracking the deasphalted and demetalized oil stream in the presence of steam in a steam pyrolysis zone to produce a mixed product stream, wherein the vapor phase is passed to a pyrolysis section of the steam pyrolysis zone; and the liquid phase is discharged; d. separating the thermally cracked mixed product stream; e. purifying hydrogen recovered in step (d) and recycling it to step (a); f. recovering olefins and aromatics from the separated mixed product stream; and g. recovering pyrolysis fuel oil from the separated mixed product stream.
