Abstract:
1. An integrated hydroprocessing and fluid catalytic cracking process for the direct processing of a crude oil to produce olefinic and aromatic petrochemicals, the process comprising: a. charging the crude oil and hydrogen to a hydroprocessing zone operating under conditions effective to produce a hydroprocessed effluent having a reduced content of contaminants, an increased paraffinicity and an increased American Petroleum Institute gravity; b. separating the hydroprocessed effluent into a low boiling fraction and a high boiling fraction; c. cracking the low boiling fraction in a first downflow reactor of a fluid catalytic cracking unit in the presence of a predetermined amount of catalyst to produce cracked products and spent catalyst; d. cracking the high boiling fraction in a second downflow reactor of the fluid catalytic cracking unit in the presence of a predetermined amount of catalyst to produce cracked products and spent catalyst; e. regenerating spent catalyst from both the first and second downflow reactors in a common regeneration zone and recycling the regenerated catalyst back to the first and second downflow reactors; and f. recovering the first and second cracked product streams.
