New units for processing heavy crudes should not be designed using conventional practices or run length will be short, and product yields and quality poor. Opportunity crudes cost less than other crudes because they ...

Real retrofit examples demonstrate how crude units can be successfully optimised with crude slates currently being processed. Process design strategies are discussed in detail and highlight how retrofit targets are achieved.
When simulating or designing an unconventional heavy oil/bitumen vacuum crude unit, the sharing of operating data on cracked gas make, stripping section performance and indirect entrainment can help ensure designers make the right design choices.
Vacuun unit design influences liquid volume yields, run length, product yield and product quality when processing bitumen crude oils. These crudes require special design considerations to maintain a reasonable run length without significant economic loss.
Vacuum unit design can influence cacuum gas yield, product quality and run length. A wet vacuum unit with residue stripping achieves the highest cutpoint and produces the lowest metals content.
A process review, including the improvement of atmospheric and vacuum distillation columns, for the reformulation of the diesel pool.
