ABSTRACT:
A method for separating emulsified oil from water in petroleum production is disclosed. Low molecular weight polymers of dimethylaminoethyl acrylate methyl chloride and benzyl chloride quaternary salt have good activity as reverse emulsion breakers for freeing oil tied up as a oil-in-water emulsion. The polymer reverse emulsion breakers are preferably prepared and used as aqueous solutions to obviate the need for inversion techniques and the use of hydrocarbon compatibilizers and surfactants as required for a latex polymer.
