Question 2 (Liquid-Liquid Extraction It is proposed to reduce the concentration of acetaldehyde in aqueous solution from
Question 2 (Liquid-Liquid Extraction It is proposed to reduce the concentration of acetaldehyde in aqueous solution from 60 wt% to 5 wt%, by extraction with a solvent S at 293 K. (a) If a countercurrent multiple contact process is adopted and 0.5 kg/s of the solution feed is treated with an equal quantity of solvent, determine the number of theoretical stages required. 100% Acetaldehyde A 100% Water 50 50 w 100% Solvent S
