Claim:
1. A paraffinic solvent recovery process for treating a high paraffin diluted bitumen containing bitumen and residual water, fine solids and asphaltenes, the high paraffin diluted bitumen being derived from a paraffinic froth separation operation that separates a bitumen froth into a solvent diluted tailings component and the high paraffin diluted bitumen, comprising: pre-heating the high paraffin diluted bitumen to produce a heated high paraffin diluted bitumen; supplying the heated high paraffin diluted bitumen to a paraffinic solvent flashing apparatus; separating the heated high paraffin diluted bitumen within the paraffinic solvent flashing apparatus into a flashed paraffinic solvent component and a diluted bitumen underflow component; deriving a hot dry bitumen from the diluted bitumen underflow component; wherein the pre-heating comprises indirectly transferring heat to the high paraffin diluted bitumen from the hot dry bitumen.
