Designing a crude unit heat exchanger network

Preheat train design for heavy Canadian crudes can be very challenging, requiring an approach not normally required with other crudes

Desalting heavy Canadian crudes

Effective desalting requires large desalters and attention to all variables associated with good desalter performance

Cost-effective and reliable revamps

Test run hydraulic measurements and analysis, together with equipment know-how, can help refiners identify profitable, low-cost revamp opportunities

Maximising diesel recovery from crude

The CDU/VDU process flow scheme is reviewed, including equipment design and operating fundamentals used to maximise straight-run diesel recovery

Canadian crude processing challenges

Vacuum unit design influences liquid volume yields, run length, product yield and product quality when processing bitumen crude oils

Revamping atmospheric crude heaters

Revamp of an atmospheric crude unit heater suffering from coking caused by asphaltene precipitation resulted in an increased heater run length

Identifying poor heat exchanger performance

Identifying root causes of poor crude unit debutaniser reboiler performance and low-cost solutions that help meet exchanger original design conditions
