Abstract: The present disclosure relates to methods and compositions for reducing fouling by natural and synthetic foulants that tend to precipitate during hydrocarbon collecting, processing, transporting, and storing. The method includes applying a composition to a hydrocarbon containing the foulant. The composition includes an effective amount of a reaction product of an α-olefin/maleic anhydride copolymer and an amino-hydroxy compound. The foulants may include wax and asphaltenes, for example.

Abstract: A composition is provided that includes about 1 weight % to about 49 weight % of a copolymer including ethylene and vinyl acetate; about 1 weight % to about 49 weight % of an acrylate-containing copolymer; and about 2 weight % to about 98 weight % of a solvent. The composition can be used to decrease the pour point of a hydrocarbon, such as crude oil.

Abstract: The present disclosure relates to demulsifier compositions and methods of resolving emulsions using the compositions. The demulsifiers include modified hydroxy-succinimide copolymers. For example, the demulsifiers may include ethoxylated or propoxylated hydroxy-succinimide copolymers. The demulsifier compositions are useful for resolving oil-in-water, water-in-oil, and complex emulsions of water and oil.
