Question: A solution of 1216 kg/h containing 53% by weight of solute(A) in 42% by weight of carrier(B) with traces of 5% by weight of solvent(s). The feed is required to reduce to 3% (by weight) as a raffinate by a continuous extraction in a countercurrent extraction using pure solvent. Determine the followings: a) the ideal number of stages required for the above extraction if the composition at the mixing point is 0.21. b) S/F and Smid/F ratio for the above extraction c) the extract composition as well as extract and raffinate flow rates at final stage only. The following equilibrium data should be used in equilateral triangle: Equilibrium data Tie line data Extract Raffinate Extract Raffinate A с S А с S 0.27 0.43 0.06 0.005 0.935 0.40 0.44 0.16 0.20 0.35 0.10 0.01 0.89 0.35 0.54 0.11 0.13 0.24 0.15 0.02 0.83 0.30 0.625 0.075 0.09 0.10 0.20 0.03 0.77 0.25 0.69 0.06 0.06 0.025 0.25 0.05 0.7 0.20 0.76 0.04 0.30 0.07 0.63 0.15 0.82 0.03 0.35 0.09 0.56 0.10 0.88 0.02 0.40 0.14 0.46 0.06 0.93 0.01
