Acrolein is a useful additive for treating hydrocarbon fluids, such as crude oil, for multiple purposes including, but not necessarily limited to, reducing or preventing microbial activity, scavenging hydrogen sulfide (H2S), and/or at least partially dissolving iron sulfide (FeS). Acrolein can be stabilized against decomposition by mixing or combining it with at least one alkyl carbonate, which can also raise the flash point of the stabilized acrolein composition.

The disclosure relates to the use of ionic liquids as paraffin inhibitors, pour point depressant or cold flow improvers in the production, treatment and refining of hydrocarbon fluids.

Shelf-stabilized HS scavengers and methods for preparing such shelf-stabilized HS scavengers. In one aspect, a stabilized hydrogen sulfide scavenger configured for storage at an elevated temperature includes a base scavenger, free formaldehyde, and a stabilizing alcohol. In another aspect, a method of preparing the stabilized hydrogen sulfide scavenger includes the steps of providing a quantity of base scavenger; providing a quantity of free formaldehyde; and adding a quantity of stabilizing alcohol, wherein the quantity of stabilizing alcohol is determined as a function of the provided quantity of free formaldehyde. In yet another aspect, the stabilized scavenger includes about 25 wt. % base scavenger, wherein the base scavenger is an amine-aldehyde condensate; about 15 wt. % free formaldehyde; and between about 10 wt. % and about 25 wt. % stabilizing alcohol.

Stabilizing scavenger formulations in the presence of excess formaldehyde for storage at elevated temperatures

A scale inhibitor squeeze treatment is enhanced by injecting a pre-flush solution into a wellbore, where the pre-flush solution includes at least one organic carbonate solvent, such as a dialkyl carbonate and/or a cyclic carbonate. The use of an organic carbonate solvent can help prevent the pre-flush solution emulsion formation, help avoid water-blocking, and enhance scale inhibitor adsorption. The use of an organic carbonate solvent also permits the pre-flush solution to be free of water, in one non-limiting embodiment.

Carbonate-based solvents for scale-squeeze enhancement

A method for direct synthesis of cyclic carbonates is achieved by reacting at least one epoxide with carbon dioxide in the presence of a choline catalyst, such as choline chloride, under mild conditions such as a temperature between about 25° C. to 150° C. and a pressure of from about atmospheric to 75 psi (0.52 MPa), in a cyclic carbonate solvent. The choline catalyst may be the only catalyst used, and a co-catalyst or hydrogen bond donor is not necessary. The concentration of choline catalyst in the solvent ranges from about 0.5 mol % to about 10 mol %, based on the epoxide.

Direct synthesis of cyclic carbonates using choline chloride as catalyst under mild conditions

It has been discovered that solid contaminants in a mixture of a hydrocarbon phase and an aqueous phase may be retained in the hydrocarbon phase by introducing to the mixture an effective amount of an oil-wetting additive to retain at least a portion of the solid contaminants in the hydrocarbon phase as contrasted with an aqueous phase. The oil-wetting additive can be a surface-active additive including, but is not necessarily limited to, drilling fluid additives, surfactants, antifoulants, nanoparticles and combinations thereof.

Oil-wetting chemicals for solids retention

Catalyst fines can be removed from heavy oils, such as marine fuel oils, by introducing an additive in an effective amount to at least partially remove the catalyst fines, where the additive is an oxyalkylated acid-catalyzed alkylphenol formaldehyde resin and/or a Mannich condensate base resin copolymer.

Removing catalyst fines from heavy oils

Dispersants including at least one organic carbonate can keep deposits dispersed within hydrocarbons, where the solids are asphaltenes and derivatives from triazine-based HS scavengers.

Formulations for dispersal of byproducts of oil field scavenger slurries and asphaltene deposits

A combination of at least one basic compound, such as potassium hydroxide, together with at least one aldehyde donor can synergistically scavenge mercaptans from organic fluids, such as hydrocarbons, where 'synergistically effective' is defined as the amount of mercaptans scavenged is greater as compared with a combination where either the basic compound or the reaction product is absent, used in the same total amount.

Synergistic effects among mercaptan scavengers

It has been discovered that contaminants such as metals and/or amines can be transferred from a hydrocarbon phase to a water phase in an emulsion breaking process by using a composition that contains water-soluble C5-C12 polyhydroxy carboxylic acids, ammonium salts thereof, alkali metal salts thereof, and mixtures of all of these. The composition may also optionally include a mineral acid to reduce the pH of the desalter wash water. The method permits transfer of metals and/or amines into the aqueous phase with little or no hydrocarbon phase undercarry into the aqueous phase. Resolving the emulsion into the hydrocarbon phase and the aqueous phase occurs in a refinery desalting process using electrostatic coalescence. The composition is particularly useful in treating crude oil emulsions, and in removing calcium and other metals therefrom. The polyhydroxy carboxylic acid additionally inhibits metal corrosion of metal pipe or other equipment used in a crude unit.

Compositions and methods of removing contaminants in refinery desalting

A regeneration solvent comprised of one or more ethylene amines may contact an adsorbent bed that has been used to remove sulfur compounds from a hydrocarbon stream to extract adsorbed sulfur compounds from the adsorbent material in the bed to regenerate it. The one or more ethyleneamines may have structure (I), (II), or (III): where R, R, Rand Rare, to the extent chemically possible, independently H, C-Clinear or branched alkyl, amido (RRNC&#x2550;O), or hydroxyalkyl, where each R in the amido group is independently H or Calkyl, where Rand Rare alkylene of from 1 to 4 carbon atoms, where x ranges from 0 to 3, y ranges from 1 to 6. The regenerated adsorbent bed may be reused, either alone or in combination with a liquid-liquid extraction column, to remove sulfur compounds from a hydrocarbon stream.

Ethyleneamines for regenerating adsorbent beds for sulfur compound removal

Ionic liquid containing compositions may be used in the production, recovery and refining of oil and gas. In addition, they may be used to treat cooling water and/or to inhibit and/or prevent corrosion of metals.

Methods of using ionic liquids as corrosion inhibitors

Metals, such as mercury, may be removed from aqueous, hydrocarbon, or mixed oilfield or refinery fluids by: applying a sulfur compound having the general formula HS&#x2014;X, where X is a heteroatom substituted alkyl, cycloalkyl, aryl, and/or alkylaryl group either alone or in combination with or as a blend with at least one demulsifier, a buffering agent, a pour point depressant, and/or a water clarifier to chelate the at least one metal and form a chelate complex of the sulfur compound with the at least one metal and then separating the chelate complex from the fluid.

Metal removal from fluids

A solvent comprised of (1) a caustic and an alcohol, (2) a caustic and a quaternary ammonium hydroxide, or (3) a caustic, an alcohol, and a quaternary ammonium hydroxide may contact an adsorbent bed that has been used to remove sulfur compounds from a hydrocarbon stream to extract adsorbed sulfur compounds from the adsorbent material in the bed to regenerate it. The regenerated adsorbent bed may be reused, either alone or in combination with a liquid-liquid extraction column, to remove sulfur compounds from a hydrocarbon stream.

Regenerated adsorbent beds for sulfur compound removal

Metals, such as mercury, may be removed from glycol fluids by applying a sulfur compound having the general formula HS&#x2014;X, wherein X is a heteroatom-substituted alkyl, cycloalkyl, aryl, and/or alkylaryl group either alone or in combination with or as a blend with at least one antifoam additive, at least one demulsifier and/or a buffering agent, to chelate the at least one metal and form a chelate complex of the sulfur compound with the at least one metal and then separating the chelate complex from the fluid.
