1. Binary Distillation Column Design. From the bioethanol production process, you are assigned to do a conceptual design of distillation to concentrated ethantol-water mixture from 31.1 wt % (15 mol\%) to 85.60 wt % (70 mol\%) before purified to a final product of 97 wt%. Before using the simulation program, you make a rough estimate by the graphical method. The flowrate ethanol-water solution from the fermenter is 100kg/h. The recovery of ethanol is specified at 83.60%. You decide to heat the distillation feed to the temperature until the vapor mole fraction is at 0.10 . Hint: The phase equilibrium is on a mole basis. Therefore, use the molecular weight of ethanol (46) and water (18) to calculate from mass to mole basis
