Abstract
A imidazoline concentrate, uses of the concentrate, and methods of increasing a storage stability of solutions containing the concentrate are disclosed. The concentrate may include a reaction product of a fatty acid, an alkylene polyamine, a hydrocarbyl succinic acid or anhydride, and an alkoxylated alkylphenol component. The concentrate may contain from about 2 to about 50 wt. % of the alkyphenol component.
Claims20
A concentrate for use in providing an additive solution suitable for a pipeline fluid, a refinery fluid, an oil and gas well drilling fluid, or a petroleum product consisting essentially of
- a) a reaction product of an imidazoline, and a hydrocarbyl succinic acid or anhydride;
- b) an alkoxylated alkylphenol component;
- and,
- c) optionally, one or more of a dimer acid, a phosphate, and a polyether,
- wherein the concentrate contains from about 2 to about 50 wt. % of the alkyphenol component and the concentrate remains stable and substantially clear down to about −45° C. in the presence of alcohol, water in an amount ranging from about 5 to about 40 percent by weight based on the total weight of the concentrate, friction reducers, and other components.
A method of increasing a storage stability of a concentrate for use in providing an additive solution suitable for a pipeline fluid, a refinery fluid, an oil and gas well drilling fluid, or a petroleum product consisting essentially of blending (a) a reaction product of imidazoline and a hydrocarbyl succinic acid or anhydride with (b) from about 2 to about 50 wt. % of an alkoxylated alkylphenol component;
- and (c) optionally, one or more of a dimer acid, a phosphate, and a polyether, wherein the concentrate remains stable and substantially clear down to about −45° C. in the presence of alcohol, water in an amount ranging from about 5 to about 40 percent by weight based on the total weight of the concentrate, friction reducers, and other components.
