Illustration 10.7 A covered, baffled vessel, 0.5 m (19.7 in) diameter, 0.5 m deep is to be used for continuous extraction of benzoic acid from water (3 x 10-3 m/s 6.36 ft'/min) into toluene (3 x 10 m/s) as solvent. Liquids are to flow cocurrently upward and will fill the vessel; there will be no gas-liquid interface and hence no vortex. A six-blade, flat-blade disk turbine, 0.15 m (6 in) diameter is to be located axially and centrally, turning at 13.3 r/s (800 r/min). The liquid properties are: Water solution Toluene solution Density p Viscosity u Diffusivity D 998 kg/m³ 0.95 x 10-3 kg/m·s 2.2 x 10-9 m²/s 865 kg/m 0.59 x 10- kg/m s 1.5 x 10-9 m²/s Interfacial tension, a 0.022 N/m Distribution coefficient = Coluene/Cwater %3D 20.8 Estimate the stage efficiency to be expected.
