Advantages of Tray Dividing-Wall Columns

• The price of tray dividing-wall columns is much
  lower than usual DWC-columns
  (packing columns)
• Mass transfer efficiency by cyclic distillation
• Reduction of the residence time of liquid in the
  column
• The uniform arrangement of liquid on the tray
• The separation efficiency doesnt depend on the
  column diameter
• Any geometric configuration of the trays
• Placement packing between trays
• Better process control
• Simpler column design
• Faster and simpler installation/revamping
