Shell ConSep Tray

The latest developments in tray technology go beyond the system limits of normal trays. The Shell ConSep tray offers up to 80% higher capacity than conventional trays, and up to 40% higher capacity than any other high performance trays, while maintaining high mass transfer efficiency.


Shell ConSep™ trays utilize the principle of de-entrainment by centrifugal force to exceed the gravitational limitation of jet flood.

Key characteristics 

  • The ConSep™ tray combines the large bubbling area and liquid handling capacity of the contacting Shell HiFi trays (see right side of picture) and a centrifugal separator (see left side of picture) in a single stage: Con(tact) and Sep(arator) 
  • Ideal for increasing existing plant capacity (revamps):
    • Suitable mainly for 1-to-1 revamping of towers equipped with high performance trays
    • Does not require any welding to the tower wall
    • Provides up to 40% more capacity than any high performance tray 
  • Experience with refinery and natural-gas liquids applications 
  • Proven technology and excellent reliability based on:
    • Actual operating experience
    • Extensive research and development
    • Fractionation Research Inc (FRI) proven
