Question
4) A solvent is to be recovered by distillation from its aqueous solution. It is necessary to produce an overhead product containing 95 mol% solvent and to recover 95% of the solvent in the feed. The feed operating reflux ratio, L/D, be 1.33 times the minimum value. A total condenser will be employed. For necessary heat in the form of open steam. For the preliminary design, it has been suggested that the is availiable at the plant site in two streams, one containing 40 mol% A and the other 60 mol% A. Each stream has a total flow rate of 50 kmol/h, and each will be fed into the column as saturated liquid at this system, it is estimated that the overall column efficiency will be 70%. The relative volatility may be their optimal location. Since the less volatile component is water, it has been proposed to supply the assumed to be constant at 3.0. a. How many plates will be required? b. What will be the bottoms composition?
