3. Introduction Batch Distillation 1 L of Ethanol-H 2 O @ Azeotrope 9 L of H 2 O Re-Boiler Power @ 1500W

4. System Diagram Experimental Data Material Balance Results Without Rectification

5. REBOILER n Total = 518 moles x EtOH = 0.032 mol/mol COLUMNCOLUMN D (moles) x D (mol EtOH/mol) Q = 1500 W System Diagram CONDENSER Q

6. Experimental Data

8. Material Balance moles

9. Results Distillate Liquid Ethanol Composition = 0.350 The Time Required for the Process to Reach that Composition was around 50 min.
