You are required to design a distillation column to separate an organic mixture of 200 kmol/h. The feed is pumped from a storage tank at 30 C and 1.01bar. The feed compositions are listed in the table below. Component toluene Mole fraction 0.5 benzene 0.3 phenol 0.04 cyclohexane 0.06 ethyl benzene 0.1 It is required that less than there is 0.01% (mole fraction) ethyl benzene in the distillate and more than 99% recovery (yield) of cyclohexane in the distillate. You need to find the required thermodynamics data. (a) Decide the column operating pressure. Justify the decision. [4 marks] (b) Using FUG method, calculate N min, Rmin, R, N and feed stage. Show the key calculations. [18 marks]
