Q3: There are two feed streams A and B at their corresponding bubble points available in a plant. The streams consist of binary mixtures of methanol and water whose characteristics are given in tablel. You are given an assignment to design a distillation column, which is expected to produce a top product of 95% methanol and a bottom product of 95% water. Your supervisor fixes the reflux ratio L/D=2.0. Find the followings: X y 0 0 0.02 Table 1:Characteristics of the two streams stream Flow rate (mol/h) composition A i) Calculate D and W ii) Calculate all the flow rates in all three sections: Vn, Ln, V', L',Vm and Lm iii) From the mass and/or component balance show the intermediate operating line in terms y = mx + c, where m is the slope of the operating line and c is the intercept. Find the value of m and c iv) Determine the number of stages 0.134 0.23 0.3 B 0.04 0.06 0.08 100 0.1 100 0.2 0.3 x=0.5 0.4 x=0.5 0.5 0.6 0.7 0.8 0.9 0.95 0.36 0.41 0.58 0.66 0.73 0.78 0.82 0.87 0.91 0.96 0.98 1 1
