Integrated process for production of chemical from crude oil using slurry hydrocracking

An integrated system for converting crude oil to high value petrochemicals products, comprising:

• i. an atmospheric vacuum unit (AVU) comprising an atmospheric distillation column and a vacuum distillation column to fractionate crude oil into straight run fractions comprising, a straight run naphtha (SRN) having boiling range of C5-200° C., a middle distillate stream having boiling range of 200 to 370° C., a vacuum gas oil (VGO) with boiling range of 370 to 560° C. and a vacuum residue (VR) having boiling range above 560° C.;
• ii. a Residue Hydrocracking section comprising a slurry hydrocracking reactor and a gas-oil reactor to receive and process the vacuum residue to produce a stream comprising fuel gas in the range of C1 and C2), liquefied petroleum gas (LPG) in the range of C3 and C4, total naphtha having boiling point in the range of C5 to 200° C., middle distillate having boiling point in the range of 200 to 370° ° C. and unconverted Pitch having boiling point above 560° C. by slurry hydrocracking, wherein,
• a naphtha cracker unit operable to routing the total naphtha for production of olefins;
• a selective mild hydrocracking unit operable to routing the middle distillate stream;
• and
• the gas-oil reactor of the Residue Hydrocracking section operable to partly routing the VGO,
• iii. a selective mild hydrocracking unit to receive the middle distillate stream from the atmospheric distillation unit and process the said stream to produce a stream comprising fuel gas, LPG, light naphtha having boiling range between C5-100° C., heavy naphtha having boiling range between 100 to 200° ° C. and diesel stream having boiling point above 200° ° C., wherein, the light naphtha is routed towards a naphtha cracker unit;
• iv. an aromatic complex comprising reformer, transalkylation unit, isomer unit, p-xylene extraction unit and aromatic extraction unit, wherein the aromatic complex receives heavy naphtha and process said heavy naphtha to produce hydrogen gas, off gas, LPG, non-aromatic raffinate, benzene, p-xylene and heavy aromatics;
• v. a naphtha cracker unit to receive SRN and process said SRN to produce a stream comprising ethylene rich fuel gas stream, C3 and C4 olefin rich mixed stream, monoaromatic rich pyrolysis gasoline stream and pyrolysis fuel oil stream, wherein,
• the aromatic complex operable to routing the monoaromatic rich pyrolysis gasoline stream to produce benzene and p-xylene;
• Residue Hydrocracking section operable to routing the pyrolysis fuel oil stream to crack further.
• vi. a C2-splitter unit to receive the ethylene rich fuel gas stream and process the said stream to produce ethylene and fuel gas;
• and
• vii. a propylene recovery unit to receive the C3 and C4 olefin rich mixed stream and process the said stream to produce propylene, 1-butene, butadiene and LPG.
