Distillation: Deriving McCabe-Thiele using MB & EB

0:00 Foundation of McCabe-Thiele
0:10 Equilibrium stage definition
0:30 Overall tray efficiency
0:51 Energy balance needed?
2:08 When no heat loss and ∆Hvap constant
2:22 Sketchy EB
3:14 Divide and conquer
3:28 Upper part
4:27 Lower part
5:16 Boilup ratio
5:33 Feed section and q
6:07 What is q? (q-line)
6:38 Our goal (quick and sketchy)
7:41 Drawing triangles
9:09 Feed location
9:40 Equilibrium stage vs triangle
10:18 When is MB straight line? (EB?)
11:54 Slope of q-line (try yourself!)
12:39 Summary of McCabe-Thiele

How to make mass (and energy?) balances for a distillation problem (for a binary mixture) and draw them in an x-y-diagram.

This is the McCabe Thiele graphical method for solving distillation problems
