CONFIGURATION FOR OLEFINS PRODUCTION Russian patent published in 2023 - IPC C10G53/06 C10G67/16 

FIELD: petrochemical products.

SUBSTANCE: invention relates to a process for converting total crude oil and other heavy hydrocarbon streams to produce olefins and aromatics, and the process includes: separating the total crude oil into at least a light boiling fraction, a medium boiling fraction and a high boiling residue fraction; separating the high-boiling fraction in the solvent deasphalting unit to obtain a deasphalted oil fraction and a pitch fraction; destructive hydrogenation of the medium-boiling fraction and the deasphalted oil fraction to produce a hydrotreated effluent; feeding the hydrotreated effluent and the low-boiling fraction to a steam cracker to convert the hydrocarbons therein into one or more light olefins and pyrolysis oil. The invention also relates to a system for converting whole crude oil and other heavy streams into olefins and a system for converting crude oil into chemicals.

EFFECT: effective conversion of vacuum residues, while minimizing the conversion of petrochemical products and maintaining a lower tendency to coke in a steam cracker.
