| Bubble cap tray is featured with high flexibility and capacity. its best to used for low liquid load and high turn down ratio. |
|
Valve tray is featured with:
1. High capacity, 20~40% over bubble cap try due to vapor blows horizontal and reduce the entrainment, also valve tray gives higher open rate.
2. Higher operation flexibility compared with bubble cap tray.
3. Higher separation efficiency as no barrier on the tray deck, thus little liquid gradient and vapor spread evenly.
4. Lower pressure drop. The vapor tunnel is much simple than bubble cap.
5. Simple design in structure and easy for fabrication.
