Example A continuous fractionating column is to be design to separate 30 Ib/h of a mixture of 40 percent benzene and 60 percent toluene into an overhead product containing 97 percent benzene and a bottom product containing 98 percent toluene. These percentages are by weight. A reflux ratio of 3.5 mol to 1 mol of product is to be used. The molal latent heats of benzene and toluene are 7,360 and 7,960 cal/mol, respectively. Benzene and toluene form an ideal system with a relative volatility of about 2.5; the equilibrium curve is shown in Figure below. The feed has a boiling point of 95 °C at a pressure of 1 atm.
(a) Calculate the moles of overhead product and bottom product per hour.
(b) Determine the number of ideal plate and the position of the feed plate:
(i) if the feed is liquid and at its boiling point.
