It is desired that the bottom product flow rate is 60 kgmol/h and its composition is 4 mol% benzene. Equilibrium data and equilibrium curve for benzene-toluene system at 101.3 kPa pressure is given in the following. a) Calculate the flow rate of overhead product and its composition b) If the reflux ratio is 2Rmn, find the number of theoretical tray needed and location of feed tray. c) Calculate the flow rate of liquid (Ln) in tower.
