' A continuous fractionating column is to be designed to separate 30.000 kgf'h o1 mixture of 40 percent benzene and 60 percent toluene into an overhead produc containing 9? percent benzene and a bottom product containing 98 percent toll These percentages are by weight. A reflux ratio of 3.5 mol to 1 mol of product be used. The molal latent heats of benzene and toluene are 7360 and 7960 calf; respectively. Benzene and toluene form an ideal system with a relative volatili1 about 2.5. The feed has a boiling point of 95\"C at a pressure of 1 atm. (a) Calc' the moles of overhead product and bottom product per hour, (.6) Determine the number of ideal plates and the position of the feed plate (i) if the feed is liquid its boiling point; (it) if the feed is liquid and at 200C (specic heat 0.44 calfg-D (in) if the feed is a mixture of two-thirds vapor and one-third liquid
