Abstract (en)
[origin: WO9427701A1] Described is a method of removing water from waste oil consisting of either an oil-in-water or a water-in-oil emulsion using compounds selected from (A) the group comprising alkoxylation products of fatty alcohols and corresponding amines with 8 to 22 C-atoms and/or (B) the group comprising aliphatic monoalkylsulphates and monoalkylsulphonates with 8 to 22 C-atoms and subsequently separating the two phases.
