Draw Diagram for Process Separating Ethanol and Water

Question

A distillation column separating ethanol and water has a feed of 1000mol/hr of a 25% mol% ethanol mix. There is a distillate product of 500mol/hr of 70% ethanol coming off the total condenser, using L/D ratio of 3.

a.    Show a diagram of this process.
b.    Making use of the fact that the equilibrium Yetoh = 0.7 when Xetoh = 0.6, give the concentration of ethanol in the vapor coming off tray #2? Show all the work.

Summary

The question belongs to Chemical Engineering and it is about a distillation column separating ethanol and water. The diagram for this process needs to be drawn and the concentration of ethanol in the vapor also needs to calculated.

Note: The solution is in handwritten format.

    Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
