LIQUID-LIQUID EXTRACTION -UNDERSTANDING TERNARY DIAGRAM

Chemical Engineering Liquid Liquid Extraction Ternary Triangular Diagrams.
There has been a number of questions about how we obtained line E1R1. The first step you have to do is to approximate a tie line that passes through point M. You can use the tie line above and below to approximate a tie line with similar slope making sure it passes through point M. Points R1 and E1 can be found on the miscibility boundary, that's how line E1-R1 was drawn. Please see this slide show video on how find the line if it is not already on a tie line - • Answer to E1R1 2020
