C2. Derive Eq. (13-18).
C3. For fractional extraction outline in detail a solution procedure for (a) case 1, (b) case 2, and (c) case 3.
C4. Develop the solution method for a dilute multicomponent extraction in a cross-flow cascade. Sketch the McCabe-Thiele diagrams.
C5. Single-stage systems (N = 1) can be designed as countercurrent systems, Figure 13-4, or as cross-flow systems, Figure 13-9. Develop the methods for both these designs. Which is easier? If the system is dilute, how can the Kremser equation be used?
C6. Prove that the locations of streams M, EN, and R1 in Figure 13-21A lie on a straight ...
