Demulsification of bitumen emulsions using branched water soluble quaternary ammonium-containing polymers
Patent
·
OSTI ID:5876948
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/sup 0/ and 160/sup 0/ C wherein the demulsifier of the invention is contacted with the bituminous emulsion.
