Use of Shell and Tube Heat Exchanger in Oil & Gas / Petrochemical industry

  • Crude oil refining (preheating, distillation, condensation).
  • Natural gas processing (cooling, liquefaction).

Chemical synthesis (reactor heating/cooling).

Handles high pressure & temperature.
Better for fouling & viscous fluids.
Longer lifespan in harsh environments.

 Shell and Tube Disadvantages

 Bulky & heavy (large footprint).
 Lower efficiency than PHE for low-viscosity fluids.
 Harder to clean (fixed tube sheet designs).

 Plate Heat Exchanger Advantages

 Compact & lightweight (saves space).
Higher thermal efficiency (close temp. approach).
 Easy to clean & expand (add plates for more capacity).

 Plate Heat Exchanger Disadvantages

 Not for high-P/high-T (gaskets fail).
Clogs easily with particulates.
Gasket degradation (requires periodic replacement).
