Benzene is to be recovered from an aqueous waste stream by continuous distillation. The feed contains 15 mol% of Benzene (85 mol% of water). Benzene of at least 90 mol% purity is wanted and the aqueous effluent must not contain more than 5 mol% ethanol. The feed will be a saturated liquid. Reflux ratio R=L/D = 1.3 Number of stages = 15 Determine the vapor and liquid flowrates in the column. Determine the column diameter. Flow rate Density (kmol/min) (kg/m3) 876 0.874 Molecular weight (kg/kmol) 78 Liquid Vapor 78 Determine the following: a. Calculate the diameter of the distillation column, taking 82% flooding at the maximum flow rate. Plate spacing = 0.6 m b. Determine the number of passes c. Determine if the column will have weeping. d. Complete the provisional plate design (i.e. calculate Ac, Ad, An, Aa,Ah). e. Calculate the plate total pressure drop. Show all the steps and write the final
