SUPERFRAC® XT trays
Koch-Glitsch has successfully designed large diameter columns that use multi-pass design techniques in 6-pass or 8-pass configurations.
 
 SUPERFRAC® XT tray
 
  • Diameters from 13 ft [3962 mm]
  • Difficult or high purity separations
  • Maximum tray efficiency and capacity 
  • Multiple downcomer designs

 

In larger diameter columns, typical multi-pass designs are limited to four passes. However, for applications that require more than four passes, the proprietary multi-pass downcomer design can be used to reduce weir loading and improve the capacity of the column.
 
Large diameter columns can use these multi-pass design techniques in 6-pass or 8-pass configurations. Modest capacity increases with these trays are possible in comparison to the best designed 4-pass SUPERFRAC® trays.
 
The downcomer configuration for a multi-pass design typically is the multi-chordal design; however, almost any other configuration can be used.
