IPA 100 20 80 40 60 60 40 80 20 100 0 20 40 60 80 100 Wate Cyclohexane Use the equilateral triangle above to respond to questions below. Why might a process design engineer avoid an extraction that would have higher than 20% IPA in the solvent phase? Neglecting solubility of water and cyclohexane in each other, what is the molar distribution coefficient (K) for IPA in cyclohexane at 80% cyclohexane. Also find K' If the aqueous feed has >50% IPA Which cascade configuration (co-, counter-, cross-current with even solvent splitting, cross-current with diminishing solvent per subsequent stage) would best suit an IPA extraction while limiting the concentration of IPA in cyclohexane to
