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 E1R1 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
