Demulsification of bitumen emulsions
Patent
·
OSTI ID:5514852
A process for recovering bitumen from oil-in-water (O/W) emulsions is disclosed wherein water-soluble demulsifiers are used. These demulsifiers are salts of polymers and/or co-polymers of specific cationic monomers. 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.
