What determines the flexibility of a tray?
Several items affect the flexibility of trays. Among them and their effects are the following: a) Liquid rate. The higher the liquid rate, the greater the leakage rate that can be accepted. However, the percent leakage that can be tolerated remains the same. b) Pressure drop. A high pressure drop gives a higher unit reference. c) Number of flow paths. The fewer the number of flow paths to keep active, the greater the flexibility. d) Tray spacing. Large tray spacings permit designing with higher pressure drop and higher unit reference. e) Foaming. Non-foaming systems can be designed to operate at higher pressure drop and unit reference than foaming systems.
