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

System Diagram Experimental Data Material Balance Results Without Rectification

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

Experimental Data

Material Balance moles

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

Experimental Data

Material Balance moles

Results Distillate Liquid Ethanol Composition = The Time Required for the Process to Reach that Composition was around 120 min.

Conclusions

Conclusion Reflux increases the time of the distillation process while increasing distillate purity.
