5. Discussion
- Sensitivity Analysis: Increasing reflux ratio from 1.5 to 2.0 improved kerosene/diesel separation (5% reduction in 95% point overlap) but increased reboiler duty by 18%.
- Limitations: HYSYS assumes theoretical stages; actual tray efficiency (~65%) should be applied for design.
- Potential improvements: Add steam stripping to reduce residue volatility.
- Reflux ratio: 12 to 20 (typical for C4 splits).
- Number of stages: 80 to 120.
- Feed stage: Middle (Stage 50).
