Because of environmental considerations, acetone must be removed from air used in your chemical plant before the air is released into the atmosphere. The acetone is removed by absorbing it into water and distilling the water to produce and acetone-rich stream and a water-rich stream.

Two streams enter the process as listed in the table below. The first is the dirty air stream, which has a total mass flow rate of 3500 kg/hr. The second it a pure water stream.

Three streams exit the process as shown in the table, a pure air strearn, an acetone-rich liquid. and a water rich-liquid. The flow rate of the water-rich outlet stream has been measured to be 650 kg/hr.
