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.
Claims18
An emulsion, comprising water, an oil, and a composition, wherein the composition comprises an effective amount of a demulsifier, the demulsifier comprising a modified hydroxy-succinimide copolymer, wherein the modified hydroxy-succinimide copolymer comprises a structure selected from formula 1 or formula 2:
- wherein R is a C8 to C36 alkyl group, X is linking group, each m is independently selected from 1 to 50, and n is selected from 5 to 200.
A method of resolving an emulsion, comprising:
- providing an emulsion including water and an oil,
- adding a composition to the water, the oil, and/or the emulsion,
- wherein the composition comprises an effective amount of a demulsifier, the demulsifier comprising a modified hydroxy-succinimide copolymer, and
- separating the water from the oil,
- wherein the modified hydroxy-succinimide copolymer comprises a structure selected from formula 1 or formula 2:
- wherein R is a C8 to C36 alkyl group, X is linking group, each m is independently selected from 1 to 50, and n is selected from 5 to 200.
