(a) Ethanol and water form a minimum-boiling azeotrope. Azeotropic distillation of mixtures of ethanol and water can be carried out using cyclohexane as entrainer. Cyclohexane forms a heterogeneous azeotrope with water which boils at a temperature lower than pure ethanol and water. Sketch a simple but clear flow diagram for azeotropic distillation of a mixture of ethanol and water using cyclohexane as entrainer. Specify the components in each stream. [10 marks] (b) Consider a mixture of acetone (normal boiling point =56.2C ) and chloroform (normal boiling point =61.1C ) to be separated by a simple distillation column. The mixture forms a maximum-boiling azeotrope with 34.5mol% acetone. The azeotrope boils at 64.5C at atmospheric pressure (101.3 kPa ). Explain, using an appropriate sketch of a simple distillation process, what would you expect as distillate and bottoms if the feed contains 50mol% acetone and why. [5 marks] (c) Using the information given in (b) and the formulae given below, estimate the activity coefficients of acetone and chloroform in a liquid mixture containing 50mol% acetone.
