PrintDistillation Methods
Three different distillation methods are commonly used to generate laboratory data on crude oil:
- True Boiling Point Distillation (TBP)
- ASTM Distillation (ASTM)
- Equilibrium Flash Vaporization (EFV)
The degree of separation between the distillation fractions obtained in these methods decreases significantly as one moves down the list from TBP through ASTM to EFV. Each method and the associated distillation data have different applications in the refinery practice.
