Downcomer Tray Features Unique Geometry
The Steparc downcomer tray incorporates a highly sloped downcomer with a multichorda ] (modified arc) shaped bottom section. Fluid enters the top as a low-density frothy mixture and exits essentially as a clear liquid. This design maximizes vapor capacity while maintaining a high liquid-handling capacity. The multi-chordal bottom shape proportions the liquid evenly onto the tray deck to create a plug flow across the tray bubbling area, and its longer release length lowers the momentum of the liquid entering the tray and promotes faster vapor/liquid mixi...
