Abstract:
Self-compatible heavy oil streams are produced from converted and/or desulfurized fractions. In a preferred embodiment, an incompatibility stream is added to the converted and/or desulfurized stream to reduce the solubility number of the stream. After using a water wash to remove incompatible material, a lighter fraction is removed from the stream to increase the solubility number.
