Acetone is used in the manufacture of many chemicals and also as a solvent. In its latter role, many restrictions are place on the release of acetone vapor to the environment. You are asked to design an acetone recovery system having the flowsheet illustrated in figure. As a starting point, make a material balance for the system. All the concentrations shown in figure of bth gases and liquids are specified in weight percent to make the calculation simpler.
