Expanded ternary diagram of streams and LLE tie-lines at the extractor. The blue line and light blue dashed-line denote the LLE tie-line data originally shown in Fig. 2. The F and S squares represent feed and solvent compositions, and circles E and R denote extract and raffinate compositions, respectively. M indicates the mixture composition of feed and solvent. Distances among the streams differ from the material balances obtained via the lever rule due to the discontinuous scale of the illustration
