4. Process Drum Heuristics

5. Pressure Vessel Heuristics

6. Pressure Vessels .
Both vertical and horizontal vessels are used in practice
A reactor is simply a pressure vessel in many cases
Towers can also be considered pressure vessels -

7. Storage Tank Heuristics

8. Storage Tanks Storage is required for raw materials and products
Capacity can have a significant effect on economics of the process
Capacity is determined by production rate / raw material consumption -
