A countercurrent extraction system uses 3 steps for acid extraction acetic acid/water/isopropyl ether at 20°C and 1 atm. The feed consists of 40% (by mass) of acetic acid and 60% (by mass) of water. The feed is 2000 kg/h. The solvent used contains 1% (by mass) of acetic acid. It is necessary that the raffinate at the exit of the extractor contains 5% of acetic acid (by mass). Determine: The amount of solvent, extract in MS and raffinate R1 Equilibrium data: Equilibrium diagrams of the ternary system: acetic acid/water/isopropyl ether (in mass fractions at 20°C and 1 atm).
