نعم HW #7 A liquid-liquid ternary phase diagram for isopropyl alcohol (IPA), toluene, and water at 25°C is shown in the next figure. Feed flow rate is 100 kg/hr, and feed compositions 40 weight percent IPA and 60 weight percent toluene. The fresh solvent is pure water, and twice the minimum solvent rate is to be used. Determine: 1. The number of equilibrium stages required to produce a raffinate stream that contains 4 weight percent IPA.? 2. The flow rates of the two liquid phases leaving the extractor.. 3. The recovery of isopropyl alcohol. E OF x, (XIPA) 20 8 60 80 100 20 x(%Water) 60 RO 100
