Liquid extraction
Document Content and Description Below
Liquid extraction Liquid –liquid extraction Sheet (6) 1) It is proposed to reduce the concentration of acetaldehyde in aqueous solution from 60 per cent to 10 per cent by mass, by extraction w... ith solvent S at 293 K. If a countercurrent multiple-contact process is adopted and 0.025 kg/s of 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 per cent 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.
