Homework Problems for the Chapter10, CENG 380 Sprig 2022 Due on 3/25/2022 3/16/2022 Problem 1. We are distilling a mixture of methanol and water in a sieve plate column operating at fv % of flooding vclocity. The feed containing fm mole % methanol is a saturated liquid. The mole% of methanol in the distillate stream is dm. The mole% of methanol in the bottom product stream is bm. The column operates at 1.0 atmosphere pressure and L/V = LV. The flow rate of the feed to the column is Fib-moles/hr. Use a TS-inch tray spacing. The fraction of the column cross-sectional area available for vapor flow is 71. The vapor-liquid equilibrium data are available in Table 2-7 and the formulas for physical properties are shown below. Assume that the vapor phase is an ideal gas mixture and the liquid phase is an ideal solution mixture.

Find the concentration of the liquid phase at the top stage. Calculate the diameter based on the conditions at the top stage of the column. Problem 2. We are distilling a mixture of methanol and water in a column packed with dumped packins shown in Table 10-3. The column operates at lat pressure. The flow rate of a saturated liquid feed containing tim-mole.% methanol to the column is at Fib-moles/hr. The external reflux ratio is R. The distillate product contains df mole fraction methanol, whereas the bottom product contains bf mole fraction methanol. A safety factor for the cross- sectional area of a packed column is 132 Data are available in Tables 2-7 and 10-3, and the formulas in the Problem I are utilized to obtain physical properties.
