Abstract (en)
[origin: WO9427702A1] Described is a method of removing water from industrial waste oil in the form of an oil-in-water emulsion containing at least 15 % by wt. of oil using de-emulsifying agents selected from the group comprising polymers of ethylene oxide and/or 1,2-propylene oxide and obtained by the ethoxylation and/or propoxylation of alcohols or amines having up to 10 carbon atoms in the molecule.
