2. Modeling a distillation stage (tray)
2.1 Real-stage modeling and Murphree efficiency
Calculating the efficiency of a tray column, whether for distillation or gas-liquid exchange, is based on the same principles. As an example, we will treat the problem using distillation notations. In particular, mole fractions (or mass fractions) are related to the most volatile component (denoted A), and the quantities associated with the output streams of a stage are denoted by the stage index.
