ABSTRACT:
Tar sand is upgraded to produce a hydrocarbon having a low concentration of water and solids by contacting a bitumen/diluent mix with an alkoxyalkylphenol alkoxylate surfactant prior to separation of a recoverable hydrocarbon phase. The separation of the bitumen/diluent mix into a recoverable hydrocarbon phase and a water/solid phase results in a recoverable hydrocarbon phase that meets the concentration of water and solids desired by tar sand processors. A further refinement of the method involves contacting the bitumen/diluent mix with an anionic and cationic flocculant following the surfactant for further improvement in separation.
