QUESTION 1 A chemical engineering intern in Thuthuka Separations Ltd is assigned to set up a pilot distillation plant that will separate a mixture of 0.19 mole fraction of ethanol and 0.81 mole fraction of water. The ethanol/water mixture is fed to a distillation column at a rate of 580kmol/hr. The distillate stream is desired to contain 92mol% ethanol and the bottom product 99mol% of water. A reflux ratio of 2.5 is to be used for the column. The vapor-liquid equilibrium data for ethanol is presented in Table 1. Table 1: Vapor-liquid equilibrium data at 1 atm, mole fraction ethanol If the feed to the distillation column is considered to be at its bubble point to the optima plate, sketch the schematic representing this process and determine the following: i) Distillate and bottoms stream flowrates. ii) Operating lines for the rectifying and stripping sections. iii) Number of theoretical stages required for the separation
