Ternary Phase Diagrams: ConcepTest and Example Problem

Try to answer this ConcepTest and solve the example problem before using this module. Studies show that trying to answer the questions before studying material improves learning and retention. We suggest that you write down the reasons for your answers. By the end of this module, you should be able to answer these on your own. Answers will be given at the end of this module.

An example problem over ternary diagrams.
Example Problem 1

This example uses a triangular phase diagram for a tertiary system to determine compositions of outlet streams from a mixer. A stream of 50% (by mass) acetone and 50% water is mixed with a stream of pure MIBK in an extraction system. The mass feed rate of the acetone/water stream is half that of the MIBK stream. What is the outlet mass of the water-rich phase per mass of water in the feed?
