Blending & Product Tanks
The last step: streams from the process units are mixed with additives into finished gasoline, diesel, jet fuel and other products, then stored for shipping.
What it does
Each product is blended to meet its specification, for example octane and vapor pressure for gasoline. Blending can be done in line through a manifold or in batches in tanks.
Basics
| Methods | In line or batch in tanks |
| Gasoline specs | Octane, vapor pressure, sulfur |
| Ships by | Pipeline, rail, truck or marine |
Common failures
- Off specification batch that must be reblended before it can ship
Troubleshooting
- Symptom
- Blend misses octane or vapor pressure
- Likely cause
- Component qualities differ from the recipe
- What to check
- Recheck component analyses and update the blend ratios
