Problem-4 Figure-1 shows the schematic diagram for a non-reactive separation system in which the feed stream is separated into 4 streams using columns as D1, B1, D2, and B2. Using materials balance on components (data given in figure is mole fractions), find out the flow rates of streams D1, B1, D2, and B2. use excel D 035 X=0.54 * = 0.04 = 0.07 B = 0.16 = 0.42 0.24 0.18 * = 0.20 *2 0.40 70 ml/min y = 0.2 -0.15 D. 021 X = 0.54 = 0.10 = 0.15 0.01 0.10 X = 0.65 X = 0.34 B2 Figure / Schematic diagram of separation system
