7 160 cm/s of a solvent S is used to treat 400cm/s of a 10 per cent by mass solution of A in B, in a three-stage countercurrent multiple-contact liquid-liquid extraction plant. What is the composition of the final raffinate? Using the same total amount of solvent, evenly distributed between the three stages, what would be the composition of the final raffinate if the equipment were used in a simple multiple-contact arrangement? Equilibrium data: kg A/kg B: kg A/kg S: Densities (kg/m): 0.05 0.069 PA = 1200, 0.10 0.159 Pa = 1000, 0.15 0.258 ps - 800
