Abstract
The disclosure relates to improved bitumen recovery processes and systems. In particular, the disclosure teaches processes and systems for recovering heavy crude oil while avoiding fouling of equipment by recycling at least a portion of a product bitumen from a solvent recovery unit for mixing with an overhead bitumen stream that may be a diluted bitumen stream containing solvent and bitumen. The overhead bitumen stream is a near-incompatible stream and the stream of mixed overhead bitumen stream and the treated bitumen stream is a compatible stream that will not foul equipment upon heating.
