Abstract
This is a unique way of upgrading an existing refinery to process heavy bitumen. The upgrade utilizes a diluent recovery unit (DRU) in front of a Resid Hydrocracker. The diluent is light enough that the DRU does not require significant metallurgy upgrades. The corrosive, heavier material is neutralized in the Resid Hydrocracker eliminating need for metallurgical upgrades in downstream units.
