The system (1) + (2) exhibits LLE and is represented by the two-parameter Margules equation with A12 = 2.5 and A21 = 1.5.
(a) Plot the Gibbs energy of mixing across the composition range to demonstrate the LLE exists.
(b) For what composition range(s) will the system be one phase?
(c) A feed mixture with overall composition x1 = 0.25 is feed at molar rate F to a settling tank (called a decanter) and the two phases extract ( flow rate E) richer in 1 and raffinate (flow rate R) less rich in 1 separate. What are the compositions, E/F, and R/F?
