Abstract
Methods for transporting bitumen extraction product include providing bitumen-laden aromatic solvent, providing bitumen-laden paraffinic solvent, and blending the two materials. The resulting mixture can be transported through existing pipeline infrastructure and can use existing separation processing equipment, and thereby avoids the need for separate infrastructure for each composition. Combining the two compositions can also avoid undesirable asphaltene precipitation.
