This paper concerns the removal of acetone from air by absorption in water in a packed column and recovery of acetone from water by pervaporation from its dilute aqueous solution. The measurements were carried out in a laboratory scale absorption column and a laboratory scale pervaporation unit. The absorption with Sulzer-packing was a suitable process for the removal of acetone vapours: a satisfactory removal efficiency was achieved. Using a CMG OM-10 pervaparation membrane from Celfa high fluxes and separation factors were obtained for the removal of acetone from water. Models were formulated to determine the most effective operating parameters which minimize the costs. According to the experiments and calculations the proposed absorption-pervaporation system can be technically feasible and economically attractive method for vapour absorption and recovery.
