3. A 200 lbmol/hr stream that is 95 mole% methylformate and 5% methanol is to be recovered from top of a distillation column. The feed to the column is 20 mole% methylformate and 80 mol% methanol, and 98% of the methylformate entering the column is contained in the distillate stream leaving the top of the column. (30 points) • Draw and label a flow chart of the process and do the degree of freedom analysis • Calculate the mass and mole fractions of methanol in the bottom stream and determine the molar flow rates of methanol and methylformate in the bottom and feed streams. Molecular weight of methanol = 32.04 g/mol Molecular weight of methylformate = 60.05 g/mol
