resumo “método para separar uma emulsão de óleo em água” incorporações da presente divulgação incluem um método para separar a emulsão de óleo em água formada durante a produção de petróleo bruto numa fase aquosa e numa fase óleo que inclui adicionar 1 parte por milhão (ppm) a 10000 ppm de um copolímero catiônico a base de n-vinil-pirrolidona na emulsão de óleo em água, com base no volume total da emulsão de óleo em água, para formar uma fase aquosa e uma fase óleo, e separar a fase aquosa da fase óleo. 1/1 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.
