Distillation
Separation of a binary mixture using distillation
These are the course notes for this topic. You are expected to learn the following:
1) the presentation of vapour liquid equilibria in x-y diagram
2) the drawing of continuous distillation column including a total condenser at the top and a reboiler at the bottom
3) Total flows of feed, distillate and bottom product and their compositions
4) How to do material balance for the top section and obtain the relationship between x and y setting y as the subject of the equation and thus get the UPPER OPERATING LINE
5) How to repeat step 4) for the lower part of the column to obtain the lower equilibrium diagram
6) How to carry out material balance around the feed plate for various scenarios of the feed (whether all liquid or partially liquid or all vapour) and thus obtain the equation of the feed line
7) How to plot the equilibrium line , upper and lower operating line and the feed line in one diagram
8) How to use the diagram obtained in 7) to determine the number of theoretical (ideal) plates for the column.
