Abstract

Demulsifiers containing an anionic surfactant selected from alkylsulfosuccinates, alkylsufonates, alkylphosphonic acids, and their salts; a nonionic surfactant selected from ethylene oxide/propylene oxide copolymers, ethoxylated fatty acids of polyethylene glycol, terpene alkoxylates, and modified alkanolamides; or a combination of an anionic and a nonionic surfactant, and methods of use thereof in breaking emulsions.
