We plan to recover acetic acid from water using 1-butanol as the solvent. Operation is at 26.7C. The feed flow rate is 10.0 kmol/h of an aqueous solution that contains 0.0046 mole frac acetic acid. The entering solvent is pure and flows at 5.0 kmol/h. This operation will be done with three mixer-settlers arranged as a countercurrent cascade. Each mixer-settler can be assumed to be an equilibrium stage. Kd= 1.613 Find the exiting raffinate and extract mole fractions.
