Question 3 A distillation column is to be designed to separate the binary mictures A and B) for System ill using equilibrium curve diagram as shown in Figure 3. Using McCabe-Thiele graphical construction answer the following questions for System II a) Calculate the minimum reflux ratio (R) to effect the separation, b) Calculate reflux ratio (R) if R: 15x Rain c) Determine the number of equilibrium stages for reflux ratio (R) in part b) d) Determine the feed location for reflux ratio (R) in part b) ) Determine the number of equilibrium stages required at total reflux ) Calculate the molar flow rates (in kmol/h) of distillate and bottoms Data: Equilibrium curve diagram for System II is given in Figure 3. For system Ill (Figure 3), the following additional information is given Feed = 5000 kmolh; Feed is an equimolar mixture of liquid and vapour The composition of component A in Feed - 40% . The composition of component Ain Distillate = 80% minimum The composition of component A in Bottoms - maximum Please Note: All percentages given are in a mole basis. Page 7 of
