A method is provided for determining the solubility parameters for a process stream via the joint use of turbidimetric detection of asphaltenes flocculation, which is used to determine and detect the onset flocculation of asphaltenes of the process stream, and a refractive index to determine the process stream solubility parameters such as the solubility blending number and insolubility number.

Method of determining the stability reserve and solubility parameters of a process stream containing asphaltenes by joint use of turbidimetric method and refractive index

Contaminants, such as volatile organic compounds and hydrogen sulfide, may be removed from a gaseous feedstream by introducing the gaseous feedstream into a treatment chamber containing a liquid medium comprising a hydrogen sulfide or mercaptan scavenger or a blend comprising (i) an absorbent and (ii) a glycol ether and/or C-Calcohol, wherein the glycol ether and/or alcohol enhances the solubility of the contaminant in the absorbent.

Water-soluble polymers may be added to an aqueous system to inhibit or decrease scale deposition within the aqueous system. In a non-limiting embodiment, the water-soluble polymer(s) may be or include polymaleates, polyacrylates, copolymers thereof, and combinations thereof. The treated aqueous system may include a decreased amount of scale deposition as compared to an otherwise identical aqueous system absent the water-soluble polymer(s).

Methods of decreasing scale in aqueous systems

Biological source oils, including, but not limited to, algae oil, stabilize the presence of asphaltenes in petroleum feedstocks, such as crude oil, to help avoid or prevent fouling and/or corrosion in the production, transferring and processing of the petroleum feedstocks. Chemical additives such as phenol-based resins, and reaction products or combinations of long chain alpha-olefins and/or small chain aldehydes and/or long chain alkyl phenate sulfides and/or metal oxide-based colloidal hydrocarbon-based nanodispersions, may also stabilize the presence of asphaltenes in petroleum feedstocks. By 'stabilizing' is meant keeping the asphaltenes in solution in the petroleum feedstocks.

A method for producing carbon nanotubes and/or fibers, such as carbon nanotubes, involves sparging a gas (such as carbon dioxide) through a liquid hydrocarbon (such as crude oil) in the presence of an effective amount of metal oxide particles (such as MgO, AlO, CeO, and/or SiOnanoparticles having a size in the range from about 2 nm to about 10 microns, and which may have a bimodal particle size distribution) at a temperature in a range of between about 70 to about 350&#xb0; C. to produce carbon nanotubes and fibers having a size range of from about 50 nm to about 20 microns.

Method of manufacturing carbon nanotubes and fibers using catalytic metal oxide nanoparticles

A composition useful for scavenging hydrogen sulfide by admixing metal carboxylates which have high viscosity due to polymerization and a viscosity improver selected from the group consisting of glycol ethers having from about 4 to about 10 carbons and alkyl alcohols having from about 1 to about 4 carbons.

Low viscosity metal-based hydrogen sulfide scavengers

The stability of an oil-based fluid crude oil fluid may be determined by measuring a first RI value of the crude oil that does not comprise a solvent where the first RI value is used to determine a first solubility parameter therefrom. A second RI value may be taken from the crude oil at a point of asphaltene flocculation during a turbidimetric flocculation titration. The second RI value may be used to determine a second solubility parameter. A process for refining the crude oil may be controlled by maintaining the process or implementing a change to the process based on a ratio of the first solubility parameter to the second solubility parameter.

Methods of determining crude oil stability

Biological source oils, including, but not limited to, algae oil, stabilize the presence of asphaltenes in petroleum feedstocks, such as crude oil, to help avoid or prevent problematic issues caused by the asphaltenes, such as sludges, plugging, deposits, fouling and/or corrosion in the production, transferring and processing of the petroleum feedstocks. Chemical additives such as phenol-based resins, and reaction products or combinations of long chain alpha-olefins and/or small chain aldehydes and/or long chain alkyl phenate sulfides and/or metal oxide-based colloidal hydrocarbon-based nanodispersions, may also stabilize the presence of asphaltenes in petroleum feedstocks.

A process for refining crude oil can be controlled to mitigate fouling by deploying a refractive index probe at a location suitable for making a crude oil stability determination, wherein the crude oil stability determination is relevant to controlling the refining process; making a measurement of crude oil stability; and then controlling the process for refining crude oil by maintaining the process or implementing a change to the process, based upon the determination of crude oil stability. This concept can also be applied to transporting, blending, and storing crude oil.

Process for predicting the stability of crude oil and employing same in transporting and/or refining the crude oil

A method for detecting the formation of at least one phase in a mixture, particularly a hydrocarbon mixture. The method may include using a probe to expose a portion of the mixture to electromagnetic radiation to determine the value of a parameter of interest indicative of the formation of a phase. The method may also include using the value of the parameter of interest with a correlation between a known property of the mixture and the value of a parameter of interest to detect the formation of a phase.

Optical method for determining fouling of crude and heavy fuels

Solid organic acids may be introduced into hydrocarbon solvents to form dispersions; the dispersions in turn may be introduced into crude oil. A wash water may be added to the crude oil to create an emulsion. The organic acids may transfer metals and/or amines from a hydrocarbon phase into an aqueous phase in an electrostatic desalter which resolves the emulsion into the two phases. Suitable solid organic acids include, but are not necessarily limited to, C2-C4 alpha hydroxyacids, such as, but not necessarily limited to, glycolic acid, malic acid, maleic acid, malonic acid, succinic acid and even sulfamic acid, chloroacetic acid, thiomalic acid, including esters of, polymers of, amine salts of, alkali metal salts of, and/or ammonium salts of all of these acids.

Method of injecting solid organic acids into crude oil

The hydrolytic stability of magnesium overbased products is significantly improved by the addition or inclusion of a mixture or reaction product of an alkylphenol resin with a mixture of an alkenyl succinic anhydride and the acid thereof, and an alkyl amine. These magnesium overbased products are useful additives to fuel oils to improve their corrosion-causing tendencies. In one non-limiting embodiment, the alkylphenol resin is nonylphenol resin and the succinic anhydride is a partially hydrolyzed succinic anhydride having from 14 to 26 carbon atoms, along with the acid thereof. The mixtures and reaction products also serve as asphaltene inhibitors in the fuel oils.
