Problem Statement #2: You desire to separate a subcooled (q = 1.2), 60 mol/s feed of 30% methanol in water, subject to the constraints that your product methanol is 85% pure and the product water contains 2% methanol. Outfit the column with the standard total condenser and partial reboiler. You may also assume that the assumptions of constant molar overflow are valid, despite the difference in enthalpy of vaporization of the components To begin evaluating the design space, determine and the minimum number of stages, the minimum reflux ratio, and the minimum boilup ratio (corresponding to the minimum reflux ratio).
