Abstract:
The present invention relates to a process for upgrading refinery heavy residues to petrochemicals, comprising the following steps of: (a) separating a hydrocarbon feedstock in a distillation unit into a to overhead stream and a bottom stream (b) feeding said bottom stream to a hydrocracking reaction area (c) separating reaction products, which are generated from said reaction area of step (b) into a stream rich in mono-aromatics and in a stream rich in poly-aromatics (d) feeding said stream rich in mono-aromatics to a gasoline hydrocracker (GHC) unit, (e) feeding said stream rich in poly-aromatics to a ring opening reaction area.

Claim (Index 39):
An integrated process for producing petrochemicals and fuel products from a crude oil feed comprising:\n 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; 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 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, 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; 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; processing heavy oil in the vacuum gas oil range from the GOHP zone in a base oils production center, including catalytic dewaxing and hydrofinishing operations, and recovering base oils.
