Process and system for conversion of crude oil to petrochemicals and fuel products integrating delayed coking of vacuum residue

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), at least
• a first VDU fraction comprising vacuum gas oil, and
• a second VDU fraction comprising vacuum residue;
• coking at least a portion of the vacuum residue to a delayed coking zone and recovering a coker naphtha stream, a coker gas oil stream and petroleum coke;
• hydroprocessing in a distillate hydroprocessing (DHP) zone middle distillates from the second ADU fraction and recovering 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;
• hydroprocessing in a gas oil hydroprocessing (GOHP) zone vacuum gas oil from the first VDU fraction and coker gas oil from the coking step, and recovering a first GOHP fraction containing components boiling at or below an atmospheric residue end boiling point and including LPG, naphtha and middle distillate range components, and a second GOHP fraction containing heavy oil, which is hydrotreated gas oil or unconverted oil in the vacuum gas oil range;
• steam cracking, in a mixed feed steam cracking (MFSC) zone, naphtha from the first ADU fraction and raffinate derived from an aromatics extraction zone, and, in a gas oil steam cracking (GOSC) zone, heavy oil, wherein steam cracking operates under conditions effective to recover at least a mixed product stream H2, methane, ethane, ethylene, mixed C3s and mixed C4s;
• pyrolysis gas;
• and pyrolysis oil;
• recovering, from the mixed product stream, H2, methane, non-olefinic C2-C4s, and petrochemicals ethylene, propylene and butylenes,
• hydroprocessing pyrolysis gas from steam cracking 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.
