10.2 Tray Efficiencies

Tray efficiencies were introduced in Chapter 4. In this section they will be discussed in more detail, and simple methods for estimating the value of the efficiency will be explored. The effect of mass transfer rates on the stage efficiency is discussed in Chapter 16.

The overall efficiency, EO, is

(10-1)

The determination of the number of equilibrium stages required for the given separation should not include a partial reboiler or a partial condenser. The overall efficiency is extremely easy to measure and use; thus, it is the most commonly used efficiency value in the plant. However, it is difficult to relate overall ...
