ABSTRACT:
A process for recovering bitumen from oil-in-water (O/W) emulsions is disclosed wherein water soluble demulsifiers are used. These demulsifiers are cationic polymers of equal to or greater than about 2,000 molecular weight obtained by the reaction of polyalkoxydiamines with epihalohydrins. 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.
