Process and system for conversion of crude oil to petrochemicals and fuel products integrating steam cracking and fluid catalytic cracking

An integrated process for producing petrochemicals and fuel products from a crude oil feed comprising:

• separating from the crude oil feed in an atmospheric distillation unit (ADU) at least a first ADU fraction comprising straight run naphtha;
• a second ADU fraction comprising at least a portion of middle distillates from the crude oil feed, and a third ADU fraction comprising atmospheric residue;
• separating from the third ADU fraction in a vacuum distillation unit (VDU) a first VDU fraction comprising vacuum gas oil;
• processing in a distillate hydroprocessing (DHP) zone at least a portion of the second ADU fraction to produce at least a first DHP fraction and a second DHP fraction, wherein the first DHP fraction comprises naphtha and the second DHP fraction is used for diesel fuel production;
• processing in a fluid catalytic cracking (FCC) zone the first VDU fraction to produce at least a first FCC fraction corresponding to light olefins that are recovered as petrochemicals, a second FCC fraction corresponding to FCC naphtha and a third FCC fraction corresponding to cycle oil;
• processing in a mixed feed steam cracking (MFSC) zone the first ADU fraction and an aromatics extraction zone raffinate, under conditions effective to recover at least a mixed product stream comprising H2, methane, ethane, ethylene, mixed C3s and mixed C4s;
• pyrolysis gas;
• and a pyrolysis oil;
• recovering, from the mixed product stream, H2, methane, ethane, non-olefinic C3s and C4, and petrochemcials ethylene, propylene and butylenes,
• hydroprocessing pyrolysis gas from the MFSC zone in a naphtha hydroprocessing zone, and recovering hydrotreated pyrolysis gas;
• and
• separating aromatics from hydrotreated pyrolysis gas in an aromatics extraction zone for recovery of petrochemical aromatic products, and aromatics extraction zone raffinate, wherein the raffinate derived from aromatics extraction is all or a portion of the aromatics extraction zone raffinate.
