<p>Disclosed is a process for the upgrading of heavy oils and bitumens, where the total feed to the process can include heavy oil or bitumen, water, and diluent. The process can include the steps of solvent deasphalting the total feed to recover an asphaltene fraction, a deasphalted oil fraction essentially free of asphaltenes, a water fraction, and a solvent fraction. The process allows removal of salts from the heavy oils and bitumens either into the aqueous products or with the asphaltene product.</p> |
