A method to convert asphaltenes to partially oxidized asphaltenes comprising the steps of treating the reactor feed in a tubular reactor to produce a reactor effluent, introducing the reactor effluent to a disengagement zone of a vessel reactor, introducing an oxidizing agent stream to the asphaltene collection zone of the vessel reactor, reacting the asphaltenes in the asphaltene-rich fraction with oxygen from the oxidizing agent, withdrawing a bottom reactor effluent from the asphaltene collection zone, reducing a temperature of the bottom reactor effluent to produce a cooled bottom effluent, reducing a pressure of the cooled bottom effluent in a pressure regulator unit to produce a centrifuge feed, separating the centrifuge feed in a centrifuge to produce a centrate, mixing the centrate and the upper upgraded stream in a product mixer to produce a mixed upgraded stream, and separating the mixed upgraded stream in a three-phase separator.

Reactive deasphalting process

A process to produce a light hydrocarbon fraction from a heavy residue feed, the process comprising the steps of operating the first supercritical reactor such that the heavy residue feed and the supercritical water stream undergo conversion reactions to produce a reactor effluent, introducing the reactor effluent to a top inlet in a top portion of a second supercritical reactor, introducing a supercritical water stream to a bottom inlet in a bottom portion of the second supercritical reactor, operating the second supercritical reactor such that the bottom of the barrel fraction is configured to settle in the bottom portion of the second supercritical reactor, withdrawing an upgraded product stream from a top outlet in the top portion of the second supercritical reactor, and withdrawing a heavy product stream from a bottom outlet in the bottom portion of the second supercritical reactor.

Supercritical water process to produce bottom free hydrocarbons

A method for upgrading a petroleum feedstock using a supercritical water petroleum upgrading system includes introducing the petroleum feedstock, water and an auxiliary feedstock. The method includes operating the system to combine the petroleum feedstock and the water to form a mixed petroleum feedstock and introducing separately and simultaneously into a lower portion of an upflowing supercritical water reactor. The auxiliary feedstock is introduced such that a portion of a fluid contained within the upflowing reactor located proximate to the bottom does not lack fluid momentum. An embodiment of the method includes operating the supercritical water petroleum upgrading system such that the upflowing reactor product fluid is introduced into an upper portion of a downflowing supercritical water reactor. The supercritical water petroleum upgrading system includes the upflowing supercritical water reactor and optionally a downflowing supercritical water reactor.

Production of upgraded petroleum by supercritical water

This present invention generally relates to a process for upgrading and desulfurizing crude oil using supercritical water. In general, the invention provides a process for removal of contaminants from a crude oil stream by mixing the crude oil stream with supercritical water and then filtering out the precipitated solid compounds that result from mixing the crude oil stream with supercritical water.

Process to upgrade and desulfurize crude oil by supercritical water

A sequential mixer for mixing a heated hydrocarbon stream and a supercritical fluid to produce an intimately mixed stream upstream of a supercritical reactor. The sequential mixer comprising a body having a body length and a body diameter; a hydrocarbon inlet physically connected to the body, having an inlet diameter, the heated hydrocarbon stream is introduced through the hydrocarbon inlet; a mixed stream outlet physically connected to the body and fluidly connected to the supercritical reactor, having an outlet diameter; a traversing axis extending through the center of the body from the hydrocarbon inlet to the mixed stream outlet; and a plurality of fluid ports physically connected to the body, the plurality of fluid ports are arranged in a port alignment arrayed along the traversing axis, each fluid port has a port diameter and a port angle, the supercritical fluid is injected through the plurality of fluid ports.
