A1. In the figure shown, what streams are represented by point A? By point B? How would you determine the temperature of stage 2? How about the temperature in the reboiler? If feed composition is as shown, how can the liquid composition on the optimum feed stage be so much less than z?
A2. For this McCabe-Thiele diagram answer the following questions.
a. (1) The actual feed tray is?
(2) The mole fraction MVC in the feed is?
(3) The vapor composition on the feed tray is?
(4) The liquid composition on the feed tray is?
b. Is the feed a superheated vapor feed, saturated vapor feed, two-phase feed, saturated liquid feed, or ...
