ABSTRACT:
The process according to the invention for the separation of oil-in-water emulsions by treatment of the emulsions with organic ionic demulsifiers and/or inorganic demulsifiers comprises carrying out the separation in two steps by first adding an organic cationic demulsifier to the o/w emulsions, and then adding an inorganic demulsifier, separating the oil phase from the resulting two-phase system and then treating the aqueous phase first with an inorganic demulsifier and then with an organic anionic demulsifier.
