N-vinylpyrrolidone-based cationic copolymer for separating an oil-in-water emulsion

Embodiments of the present disclosure include a method of separating an oil-in-water emulsion formed during crude oil production into a water phase and an oil phase that includes adding 1 part-per-million (ppm) to 10000 ppm of an N-vinylpyrrolidone based cationic copolymer to the oil-in-water emulsi...

Summary:Embodiments of the present disclosure include a method of separating an oil-in-water emulsion formed during crude oil production into a water phase and an oil phase that includes adding 1 part-per-million (ppm) to 10000 ppm of an N-vinylpyrrolidone based cationic copolymer to the oil-in-water emulsion, based on the total volume of the oil-in-water emulsion, to form a water phase and an oil phase, and separating the water phase from the oil phase.
