A continuous fractionating column is to be designed to separate 30000lb/h of a mixture of 40% benzene and 60% toluene into an overhead product containing 97% benzene and a bottom product containing 98% toluene. These percentages are by weight. A reflux ratio of 3.5 moles to 1 mole of product is to be used. The molal latent heats of benzene and toluene are 7360 and 7960cal/gmol, respectively. If the feed is liquid and at its boiling point. (1) Calculate the moles of overhead product and bottom product per hour. ( 6%) (2) The molal latent heats of steam is 939cal/gmol and used for heating, how much steam is required per hour for the above cases, neglecting heat losses and assuming the reflux is a saturated liquid? (7\%) (3) If cooling water enters the condenser at 80F and leaves at 150F, how much cooling water is required? (7\%)
