A method for producing alkene gases from a cracked product effluent, the method comprising the steps of introducing the cracked product effluent to a fractionator unit, separating the cracked product effluent in the fractionator to produce a cracked light stream and a cracked residue stream, wherein the cracked light stream comprises the alkene gases selected from the group consisting of ethylene, propylene, butylene, and combinations of the same, mixing the cracked residue stream and the heavy feed in the heavy mixer to produce a combined supercritical process feed, and upgrading the combined supercritical process feed in the supercritical water process to produce a supercritical water process (SWP)-treated light product and a SWP-treated heavy product, wherein the SWP-treated heavy product comprises reduced amounts of olefins and asphaltenes relative to the cracked residue stream such that the SWP-treated heavy product exhibits increased stability relative to the cracked residue stream.

Upgrading of heavy oil for steam cracking process

Embodiments of a process for producing high grade coke from crude oil residue include at least partially separating, in a solvent extraction unit, the crude oil residue into a deasphalted oil (DAO)-containing stream and an asphaltene containing-stream, producing a pressurized, heated DAO-containing stream, where the pressurized, heated DAO-containing stream, mixing a supercritical water stream with the pressurized, heated DAO-containing stream to create a combined feed stream, introducing the combined feed stream to an upgrading reactor system operating at supercritical temperature and pressure to yield one or more upgrading reactor output streams comprising upgraded product and a slurry mixture, where the slurry mixture comprises sulfur and one or more additional metals. The process also may include calcining the slurry mixture at a temperature of from 700&#xb0; C. to 1900&#xb0; C. to produce a product stream comprising the high grade coke.
