C1. For Example 4-4 (open steam), show that the x intercept (y = 0) is at x = xB.
C2. Derive the bottom operating line for a column with a total reboiler. Show that this is the same result as is obtained with a partial reboiler.
C4. For a side stream below the feed:
a. Draw a sketch corresponding to Figure 4-22A.
b. Derive the operating equation and y = x intercept.
c. Sketch the McCabe-Thiele diagram.
C5. Derive the operating equations for the two middle operating sections when an intermediate reboiler is used (see Figures 4-23A and 4-23B). Show that the operating line with slope of L′/V′ goes through the point y = x = xB.
C6. Show that the total amount of cooling needed is the same for a column ...
