Topics of Discussion Background System Diagram Batch Distillation Continuous Distillation Conclusions Questions
3
Background To separate by vaporization Binary mixture Determine initial composition (BP test) Equilibrium diagrams (x,y and x,y,T) Two methods: Batch and Continuous
4
System Diagram
5
Batch Distillation Production of vapor by boiling the liquid mixture to be separated and condensing the vapors without allowing any liquid to return to the still.
6
Batch Results
9
Continuous Distillation Based on the return of part of the condensate to the still under such conditions that this returning liquid is brought into intimate contact with the vapors on their way to the condenser.
10
Continuous Results
11
Conclusions Theoretical reboiler volume not same as actual Distillate formed during total reflux Possible reflux valve malfunction Trays 1-6 below B.P. of methanol RTD’s need recalibration
