OLEFIN AND AROMATIC PRODUCTION CONFIGURATION Russian patent published in 2023 - IPC C10G45/32 C10G45/44 C10G65/12 

FIELD: oil production.

SUBSTANCE: invention relates to a process of converting whole crude oil and other high-boiling hydrocarbon streams to produce olefins and/or aromatics. The method includes separating the entire crude oil into at least a light boiling fraction, a medium boiling fraction and a high boiling residue fraction; hydrocracking the high-boiling residue fraction to form a hydrocracked effluent and separating the hydrocracked effluent to obtain a hydrocracked vacuum residue fraction and a heavy oil fraction; destructively hydrogenating the medium-boiling fraction to form a first destructively hydrogenated effluent; destructively hydrogenating the hydrocracked fraction of vacuum residues to obtain a second destructively hydrogenated effluent; mixing the first and second destructively hydrogenated effluents to form a mixture, and hydrocracking the mixture to produce a hydrotreated and hydrocracked effluent; feeding the hydrotreated and hydrocracked effluent and the low-boiling fraction to at least one of the steam cracker and the aromatics complex to convert their hydrocarbons into petrochemicals and pyrolysis oil and/or ultra low sulfur heavy fuel oil (ULSFO). The invention also concerns a system of converting whole crude oil and other high-boiling hydrocarbon streams to produce olefins and/or aromatics.

EFFECT: conversion of all crude oil, including heavier fractions of crude oil, into high-value petrochemical products.
