1. We wish to separate 5,000 kg per hour of a liquid mixture containing 50% mole methanol and 50% mole water into an overhead product containing 97% mole methanol and a bottoms product having 97% mole water using continuous distillation. A mole reflux ratio of 2 is used. Calculate: (i) the moles of the overhead product obtained per hour, (ii) the number of ideal plates and location of the feed plate if the feed is at its bubble point. Equilibrium data: 0.1 0.46 0.2 0.64 0.3 0.74 0.4 0.80 0.5 0.86 0.6 0.91 0.7 0.96 0.8 0.975 0.9 0.98 y where x = mole fraction of methanol in liquid and y = mole fraction of methanol in vapor (MWmethanol = 32 g/mol, MW water = 18)
