Isopropyl ether (E) is used to separate acetic acid (A) from water (W). The liquid-liquid equilibrium data at 25oC and 1 atm(a) One hundred kilograms of a 30 wt% A-W solution is contacted with 120 kg of ether in an equilibrium stage. What are the compositions and weights of the resulting extract and raffinate? What would be the concentration of acid in the (ether-rich) extract if all the ether were removed?(b) A mixture containing 52 kg A and 48 kg W is contacted with 40 kg of E. What are the extract and raffinate compositions andquantities?
