A method and apparatus for upgrading a hydrocarbon feedstock is provided. The method includes: supplying the hydrocarbon feedstock to an oxidation reactor, where the hydrocarbon feedstock is oxidized in the presence of a catalyst under conditions sufficient to selectively oxidize sulfur compounds present in the hydrocarbon feedstock; separating the hydrocarbons and the oxidized sulfur compounds by solvent extraction; collecting a residue stream that includes oxidized sulfur compounds; supplying a residue stream that includes oxidized sulfur compounds; supplying the residue stream to a gasifier to produce a syngas stream and a hydrogen sulfide stream; supplying the extracted hydrocarbon stream to a stripper to produce a stripped oil stream, which is then supplied to an adsorption column, such that the adsorption column can produce a high purity hydrocarbon product stream, a second residue stream, and a spent adsorbent stream, the spent adsorbent stream containing another portion of the oxidized compounds; and supplying the spent adsorbent stream to the gasifier to produce additional syngas for the syngas stream, thereby disposing of the adsorbent.


Embodiments provide a method and apparatus for recovering components from a hydrocarbon feedstock. According to at least one embodiment, the method includes supplying a hydrocarbon feedstock to an oxidation reactor, wherein the hydrocarbon feedstock is oxidized in the presence of a catalyst under conditions sufficient to selectively oxidize sulfur compounds and nitrogen compounds present in the hydrocarbon feedstock, separating the hydrocarbons, the oxidized sulfur compounds, and the oxidized nitrogen compounds by solvent extraction, collecting a residue stream that includes the oxidized sulfur compounds and the oxidized nitrogen compound, supplying the residue stream to a fluid catalytic cracking unit, and recycling liquid products produced by the fluid catalytic cracking unit to the oxidation reactor to selectively oxidize sulfur compounds in the liquid products, the portion of the liquids products including at least one of light cycle oils and heavy cycle oils.

A sparingly soluble sulfonate-metal salt particle includes the metal ion salt of an alkyl aryl sulfonate, the metal ion salt of a petroleum sulfonate and a hydrophobically modified hydrophilic polymer, and has an average particle size diameter in a range of from about 50 nm to about 450 nm and is sparingly soluble in water at room temperature. A method of producing a sparingly soluble sulfonate-metal salt particle includes the steps of introducing an aqueous solution containing a metal ion salt into a reactor, introducing an aqueous solution containing a sulfonate surfactant and a polymer into the reactor, and operating the reactor such that the sparingly soluble sulfonate-metal salt particle forms from the interaction of the metal ion from the salt, the sulfonate surfactant and the polymer.

The present application provides for an acid precursor capsule that includes an acid precursor that is a non-aqueous ester and a polymerized shell that encapsulates the acid precursor. In some embodiments, the acid precursor converts into an associated acid during a hydrolysis period while in contact with water at an elevated temperature. In further embodiments, the associated acid is soluble in water and forms an aqueous acid solution with water. In certain embodiments, the polymerized shell contains the acid precursor and prevents interaction between the acid precursor and water at the elevated temperature until the polymerized shell dissolves in the water during a dissolution period. An acid precursor capsule suspension can include the acid precursor capsule and a suspension fluid. In some embodiments, a method of treatment using acid precursor capsules is provided that includes the step of introducing an acid precursor capsule suspension into a well bore such that the acid precursor capsules contact water at an elevated temperature.

Embodiments of processes for producing propylene utilize a dual catalyst system comprising a mesoporous silica catalyst impregnated with metal oxide and a mordenite framework inverted (MFI) structured silica catalyst downstream of the mesoporous silica catalyst, where the mesoporous silica catalyst includes a pore size distribution of at least 2.5 nm to 40 nm and a total pore volume of at least 0.600 cm^(3)/g, and the MFI structured silica catalyst has a total acidity of 0.001 mmol/g to 0.1 mmol/g. The propylene is produced from the butene stream via metathesis by contacting the mesoporous silica catalyst and subsequent cracking by contacting the MFI structured silica catalyst.


A demulsification process for extracting surface active biochemical products from crude oil and its fractions when they are used as feedstock during biochemical productions utilizes subcritical/supercritical C02 as a proton pump. The process also includes a pH tuning step, thereby inducing demulsification and precipitation of biochemical products into the aqueous phase, but avoiding asphaltene precipitation by apriori addition of resinous solvents derived from crude oil or bioresources. The biochemical products are then extracted from the aqueous phase via temperature change or some other technique.


An enrichment apparatus and process for enriching a hydrogen sulfide concentration in an acid gas stream (10) to create a hydrogen sulfide rich stream for feed to a Claus. The enrichment apparatus comprises a hydrocarbon selective separation unit (102) operable to separate the acid gas stream into a hydrocarbon rich stream (14) and a purified acid gas stream (12), wherein the acid gas stream comprises hydrogen sulfide, carbon dioxide, and hydrocarbons, a hydrogen sulfide selective separation unit (106) operable to separate the purified acid gas stream (12) to create the hydrogen sulfide rich stream (18) and a hydrogen sulfide lean stream (16), the hydrogen sulfide rich stream (18) having a concentration of hydrogen sulfide, and the Claus unit (200) operable to recover sulfur (80) from the hydrogen sulfide rich stream (18).

A well completion system (10) includes tubing (16), and packers (19) that seal the annulus (24) of the well outside the tubing (16). The packers (19) are spaced to define voids in the annulus (24) that are substantially free from hydrostatic pressure. Also included are hollow sleeve valves (18) having upper and lower sealing elements (28, 30), and that have closed and open positions. Each sleeve valve (18) is positioned within the tubing (16) at a depth corresponding to a void in the annulus (24). Ports (26) extend through the sleeve valve (18) and tubing (16), so that when the sleeve valve (18) is closed, the port is closed, and when the sleeve valve (18) is open, the port is open.
