What is Acetic Acid Extraction via Isopropyl Ether about?

An isopropyl ether solvent is used to extract an aqueous acetic acid solution using countercurrent multistage extraction. The aqueous solution contains 30% acetic acid at a flow rate of 200 kg/h. The solvent flows at 600 kg/h and the desired exit concentration of acetic acid in the raffinate is 4%. To determine the compositions and amounts of the extract and raffinate, as well as the number of stages required, material balances and equilibrium data are used. The analysis shows that 3.7 stages are needed, wi
