QUESTION 2 2.1 Distillation column is used to distil a binary mixture with x,y,z as the more volatile mole fraction compositions and B(Bottoms),D(distillate),R(Reflux) and F(Feed) as molar flow rates. It is desired to control distillate composition y despite the disturbance in the feed flow rate F. All flow rates can be measured and manipulated except for F, which can only be measured. a) What are the input and the output variables? (4) b) Sketch the schematic diagram of the system. (5) c) Use the schematic diagram to construct the Feedforward and feedback control methods. (11) [20]
