PE 317 Unit operations Liquid –liquid extraction Sheet (6) 1) It is proposed to reduce the concentration of acetaldehyde in an aqueous solution from 60 percent to 10 percent by mass, by extracti... on with solvent S at 293 K. If a countercurrent multiple-contact process is adopted and 0.025 kg/s of the the solution is treated with an equal quantity of solvent, Determine the number of theoretical stages required and the mass flow rate and concentration of the extract from the first stage. 2) A solution of 10 percent acetaldehyde in toluene is to be extracted with water in a co-current unit. If 25 kg water/200 kg feed is used, the final raffinate is 0.00207 kg/kg solvent. The equilibrium relation is given by: (kg acetaldehyde/kg water) = 2.20 (kg acetaldehyde/kg toluene) Determine the mass of acetaldehyde extracted and number of stages assuming immiscible flow.
