Processes for producing petrochemical products from crude oil

A process for producing petrochemical products from crude oil, the process comprising:

• separating the crude oil into at least a lesser boiling point fraction and a greater boiling point fraction, wherein at least 90 wt. % of the crude oil is present in the combination of the greater boiling point fraction and the lesser boiling point fraction;
• hydroprocessing the lesser boiling point fraction to form a first hydroprocessed effluent, wherein the hydroprocessing of the lesser boiling point fraction occurs at a first pressure;
• hydroprocessing the greater boiling point fraction to form a second hydroprocessed effluent, wherein the hydroprocessing of the greater boiling point fraction occurs at a second pressure, and wherein the second pressure is at least 25 bar greater than the first pressure;
• and
• passing the at least a portion of the first hydroprocessed effluent to a first FCC unit and cracking at least a portion of the first hydroprocessed effluent in the first FCC unit;
• passing at least a portion of the second hydroprocessed effluent to a second FCC unit and cracking at least a portion of the second hydroprocessed effluent in the second FCC unit.

• and
• passing at least a portion of the first hydroprocessed effluent and at least a portion of the second hydroprocessed effluent to a separation unit to form a light fraction, a middle fraction, and a heavy fraction;
• passing the light fraction to a first FCC unit and cracking the second hydroprocessed effluent in the first FCC unit;
• and
• passing the heavy fraction to a second FCC unit and cracking the second hydroprocessed effluent in the second FCC unit.
