A winterized paraffin inhibitor, which is capable of being used for preventing the deposition of paraffins in hydrocarbon streams and capable of withstanding freezing or crystallization at freezing or sub-freezing temperatures, may be formed by adding an oxyalkylated branched aliphatic compound having 12 or more carbons to a high molecular weight aliphatic polymer paraffin inhibitor, the oxyalkylated branched aliphatic compound having 12 or more carbons being produced by the oxyalkylation of the branched aliphatic compound having 12 or more carbon atoms in which the branched aliphatic compound having 12 or more carbon atoms is grafted with a polyether via a ring-opening reaction, wherein the polyether is a polymer of ethylene oxide, propylene oxide, butylene oxide, and combinations thereof.

Additives for winterization of paraffin inhibitors

An oxyalkylated branched aliphatic compound produced by oxyalkylating a branched aliphatic compound having 12 or more carbon atoms in which the branched aliphatic compound having 12 or more carbon atoms is grafted with a polyether via a crosslinking reaction, wherein the polyether is a polymer of ethylene oxide, propylene oxide, butylene oxide, and combinations thereof, may be useful as an inverting aid for increasing the dissolution rate of a latex-based drag reducing agent in a liquid hydrocarbon.

Relatively low molecular weight, branched polyethyleneimine (B-PE), a specific class of polyamine, has been shown to be effective at inhibiting the formation metal naphthenate precipitate (MNP) in systems and fluids that include an organic phase and an aqueous phase where the system or fluid further contains metal ions and tetra acid, and in particular the addition of low molecular weight, B-PE molecules prevents the formation of metal naphthenate precipitates/deposits in the fluids. Inhibition of alkali earth metal naphthenates (e.g. calcium naphthenate) and alkali metal naphthenates (e.g. sodium naphthenate) are particular non-limiting embodiments.

A cleaning agent comprising a polyacrylate terpolymer and a maleic olefin compound may be added to an aqueous system having a metal surface, such as a metal surface of a heat exchanger, in a concentration sufficient to remove fouling deposits from the metal surface in neutral or alkaline conditions. The removal of fouling deposits with the application of the cleaning agent may occur while the system is shut down or in service.

A demulsifying additive comprising a branched aliphatic compound may be introduced to a stream containing mixtures of or emulsions of oil and water in an effective amount to separate water from the oil in the stream, such as separating oil from emulsified oil-in-water and/or separating water from emulsified water-in-oil in a production fluid. The branched aliphatic compound may be grafted with a polyether via a crosslinking reaction. Alternatively, branched aliphatic compounds may be crosslinked together.

Demulsifying additive for separation of oil and water

A demulsifier composition comprises an oxyalkylated polybenzoxazine having repeating units of Formula (I): wherein Ris hydrogen, a Calkyl, a Ccycloalkyl, a Caryl, a Calkylarylene, a Carylalkyl, a Cheteroaryl, or a Cheterocycloalkyl; Ris a Calkyl, a Ccycloalkyl, a Caryl, a Calkylarylene, a Carylalkyl, a Cheteroaryl, or a Cheterocycloalkyl; Ris hydrogen or a Calkyl; each occurrence of Ris independently hydrogen or a Calkyl; and p is at least 1.

Oxyalkylated polybenzoxazine emulsion breakers

A single-phase microemulsion additive may be introduced to a stream containing mixtures of or emulsions of oil and water in an effective amount to separate oil from the water in the stream and/or separating water from the oil in the stream. The single-phase microemulsion additive is formed by combining at least one demulsifier, at least one water clarifier, at least one surfactant, and optionally at least one solvent.

A method of stabilizing asphaltenes in a petroleum hydrocarbon fluid is disclosed. The method includes contacting the petroleum hydrocarbon fluid with a polybenzoxazine comprising repeating structural units of Formula (I): wherein Ris hydrogen, a Calkyl, a Ccycloalkyl, a Caryl, a Calkylarylene, a Carylalkyl, a Cheteroaryl, or a Cheterocycloalkyl; and Ris a Calkyl, a Ccycloalkyl, a Caryl, a Calkylarylene, a Carylalkyl, a Cheteroaryl, or a Cheterocycloalkyl.

Polybenzoxazine asphaltene inhibitors

A method of stabilizing asphaltenes in a petroleum hydrocarbon fluid comprises contacting the petroleum hydrocarbon fluid with a mixed phenol aldehyde derived from an aldehyde and two or more unsubstituted or alkyl-substituted monophenols, the two or more unsubstituted or alkyl-substituted monophenols comprising a first phenol which is a Clinear or branched alkyl monophenol; and a second phenol which is unsubstituted or a Clinear or branched alkyl monophenol different from the first phenol, wherein the molar ratio of the first phenol relative to the second phenol is about 4:1 to about 1:4.
