ABSTRACT:
A process for recovering bitumen from oil-in-water (o/w) emulsions is disclosed wherein water soluble demulsifiers are used. These demulsifiers are branched water-soluble quaternary ammonium-containing polymers. To resolve the bituminous petroleum emulsions, the process is carried out between 25.degree. and 160.degree. C. wherein the demulsifier of the invention is contacted with the bituminous emulsion.
