摘要： Oil-in-water emulsions are reprocessed in a particularly effective manner by a process in whicha) an oil-in-water emulsion is first subjected with the aid of a chemical emulsion breaker to a first breaking andb) the resulting water phase is fed to a micro-, nano- and/or ultrafiltration or a reverse osmosis,which is characterised in thatc) the oil phase from stage a) is combined with the oil phase from stage b) andd) the oil phases thus combined are subjected with the aid of organic emulsion breakers to a second breaking.

摘要： 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.
