4.6 Profiles for Binary Distillation

Figure 4-13 essentially shows the complete solution of Example 4-3; however, it is useful to plot compositions, temperatures, and flow rates leaving each stage (these are known as profiles). From Figure 4-13 we can easily find the ethanol mole fractions in the liquid and vapor leaving each stage. Then xW = 1 − xE and yW = 1 − yE. The temperature of each stage can be found from equilibrium data (Figure 2-3) because the stages are equilibrium stages. Since we assumed CMO, the flow rates of liquid and vapor will be constant in the enriching and stripping sections, and we can determine the changes in the flow rates at the feed stage from the calculated value of q.

The profiles are shown in Figure 4-14. As expected, ...
