Question: Question 4 (25 points) Consider a distillation tower for the separation of a mixture consisting of benzene and toluene. The feed to the distillation tower

Question 4 (25 points) Consider a distillation tower for the separation of a mixture consisting of benzene and toluene. The feed to the distillation tower is a saturated liquid (liquid at the boiling point), containing 55.0 mol % benzene and 45.0 mol % toluene. The feed flow rate is 120.0 mol/h. The tower operates at steady state at 101.325 kPa absolute. The constant molar overflow is assumed. The reflux is a saturated liquid. A total condenser is used. That is, all the vapor is condensed to a saturated liquid in the condenser. A distillate product and a bottoms product are produced. The tower operates at steady state. Show your calculations explicitly. (a) What is q? (b) If the flow rate of the liquid in the enriching section of the tower is L, =252 mol/h, calculate the flow rate of the liquid in the stripping section of the tower (m.)? (c) If the flow rate of the vapor in the stripping section of the tower is V=324 mol/h, calculate the flow rate of the vapor in the enriching section of the tower (V.)? (d) If the distillate flow rate is D = 72.0 mol/h, calculate the flow rate of the bottoms product (w). (e) As stated above Ln =252 mol/h and D = 72.0 mol/h, calculate the reflux ratio (R)
