8. Acetone is an important chemical in manufacturing process as well as an organic solvent. However, acetone may cause health hazards if released uncontrolled into the environment. Hence, it is required to recover the acetone such that the discharge meets the environment safety standards. An example of an acetone recovery system is as shown in the given figure with the respective composition of each stream. Calculate the flow rate of the unknown streams.

Acetone is an important chemical in manufacturing process as well as an organic
solvent. However, acetone may cause health hazards if released uncontrolled
into the environment. Hence, it is required to recover the acetone such that the
discharge meets the environment safety standards. An example of an acetone
recovery system is as shown in the given figure with the respective composition
of each stream. Calculate the flow rate of the unknown streams.
