(b) A saturated vapour of methanol and water contains 45 mol% methanol and is to be separated using an enriching column. 250 kmol/h is fed to the bottom of the column operating at atmospheric pressure. Vapour from the top of the column is to contain 85 mol% methanol. A total condenser operates at the top of the column with a reflux ratio of 1.5 If CMO applies, determine the bottoms composition, the internal flow rates...

Consider the phase diagram below for a mixture of chloroform and methanol, looking at how the boiling point changes with composition at constant pressure. If you started with a solution that was Xchloroform = 0.1 at a temperature of 333 K, is it possible to use fractional distillation to purify this solution to nearly 100% chloroform? Approximately what concentration (in mole fraction) would you expect you could achieve through fractional distillation? Curves calculated by mod. UNIFAC (Dortmund) Temperature Minimum Azeotrope...
