ABSTRACT:
A process for upgrading a heavy hydrocarbon includes the steps of obtaining a heavy hydrocarbon; contacting the heavy hydrocarbon with a solvent at upgrading conditions so as to produce a first product comprising a mixture of upgraded hydrocarbon and solvent and a second product comprising asphaltene waste, water and solvent; and feeding the first product to a separator to separate the upgraded hydrocarbon from the solvent. A system is also provided.
