Scavenging compounds and compositions useful in applications relating to the production, transportation, storage, and separation of crude oil and natural gas are disclosed. Also disclosed herein are methods of using the compounds and compositions as scavengers, particularly in applications relating to the production, transportation, storage, and separation of crude oil and natural gas.

Hydrogen sulfide scavengers

A composition of co-polymers, surfactants and solvents is provided for use in methods of reducing paraffin and wax deposition from crude oils in storage and transportation vessels.

Composition and method for dispersing paraffins in crude oils

Bitumen may be prepared by obtaining an inflection point value for a mixed bitumen product stream sample, and modifying the mixed bitumen product stream when the inflection point value occurs at a ratio of less than about 2 mL of added non-solvent per 1 gram of the mixed bitumen product stream sample. The inflection point value may correlate to the stability of the mixed bitumen product stream based on the amount of added non-solvent. The mixed bitumen product stream may have or include at least two bitumen feed streams.

Process for preparing blends of bitumen having known stability properties

An effective hydrogen sulfide scavenger that produces little corrosion may be prepared by reacting glyoxal with a compound having at least two primary or secondary amine groups. The subject hydrogen sulfide scavengers may be used with both the production of crude oil and natural gas, and the refining of same.

Hydrogen sulfide scavenger for use in hydrocarbons

Hydrogen sulfide evolution from asphalt or heavy fuel oil may be reduced or eliminated using an additive to act as a scavenger. Zinc, in conjunction with an additional metal selected from Fe, Mn, Co, Ni, Cr, Zr, when present in the form of nano-particles of an oxide, borate or carboxylate is an effective component is preventing or mitigating the evolution of hydrogen sulfide. The nano-particles may be used neat or as a dispersion. These metals may also be complexed and used in the form of a solution. Molybdenum, when used with one or both of Fe and Zn is also a useful in any of these forms for the same purpose.

Method for reducing hydrogen sulfide evolution from asphalt and heavy fuel oils

Corrosive amine salts in hydrocarbon streams such as desalted crude oil streams can be prevented or avoided by adding certain amine scavenging chemicals to the streams to remove the amines therefrom. Suitable amine scavengers include, but are not necessarily limited to, carboxylic anhydrides and copolymers of carboxylic anhydrides, aromatic anhydrides, isocyanates, polyisocyanates, and epoxides. The non-corrosive reaction products of the amines and/or ammonia with these scavengers are preferably oil-soluble, non-basic and thermally stable. The amine scavengers bind up and react with the amines and/or ammonia to keep them from reacting with materials such as acids (e.g. HCl) to form corrosive amine salts.

Removing amines from hydrocarbon streams

Total acid number and/or corrosiveness of a crude or refined hydrocarbon, where the total acid number and/or corrosiveness is due to the presence of acid compounds such as carboxylic acid (naphthenic acid), may be reduced by treating the hydrocarbon with a metallic overbase. The effect of this treatment may be substantially enhanced by the presence of a hydrogen transfer agent.

Method for reducing acids in crude or refined hydrocarbons

Additives may be used to lower the set up point for bitumen thereby allowing it to be transported from place to place more easily. Additives useful for lowering the set up point of bitumen include alkylphenol formaldehyde resins and oxyalkylated alkylphenol formaldehyde resins; amines and esters; solvents; and combinations thereof.

Process for improving the transfer properties of bitumen

Compounds having the formulae and general formulae: wherein each R, R, Rand Rare the same or different and may be hydrogen, an alkyl group, an aryl group, a halogen, a nitro group, an alkyl or aryl ester, and an alkyl or aryl ether;compounds having the general formula: wherein R is an alkyl, aryl or electron withdrawing group; mixtures thereof; can be used as additives for crude oil and hydrocarbons. These compounds may be used to scavenge mercaptans, sulfides, cyanides, and primary or secondary amines; either alone or in combination.

Multifunctional scavenger for hydrocarbon fluids

A process for removing a sulfur species from a stream selected from the group consisting of a hydrocarbon stream, an aqueous stream, and mixtures thereof is disclosed herein, which may include introducing a treating mixture into the stream. The treating mixture may include a compound of the general formula selected from the group consisting of: or combinations of compound (I) or compound (II). Rmay be a C-Chydrocarbyl group that is saturated, unsaturated, cyclic or branched, or may contain a heteroatom. 'A' may be an oxygen atom or a methylene group. Rmay be a C-Chydrocarbyl group that may be saturated, unsaturated, cyclic or branched, or may contain a heteroatom(s) other than C and H. The treating mixture may reduce the reactive sulfur species in the stream. The sulfur species reduced from the stream may be hydrogen sulfide, mercaptans, polysulfides, or combinations thereof.

Non-nitrogen sulfide sweeteners

Heat exchanger fouling in organic chemical production processes may be reduced using an antifoulant additive. The antifoulant additive may have one component selected from the group consisting of an alkylphosphate ester, and an alpha olefin maleic anhydride copolymer; or it may have two components selected from the group consisting of a metallic overbase, an alkylphosphate ester, and an alpha olefin maleic anhydride copolymer, wherein at least one of the two components in not an overbase. An additive having three components: a metallic overbase, an alkylphosphate ester, and an alpha olefin maleic anhydride copolymer; is also within the scope of the disclosure.

Method for reducing fouling in furnaces

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.
