Distillation efficiency McCabe-Thiele diagram

Composition and temperature profiles are shown in Figures 14.13 and 14.14. In this example we see that the vapor and liquid temperatures are rather different. This result is quite typical of absorption columns indeed, it is possible for temperature differences to be over the order of 20 K. The McCabe-Thiele diagram is shown in Figure 14.15 and the component efficiencies in Figure 14.16. The efficiencies tend to be lower than in the distillation operations considered above.
