Air coming from a painting operation contains 10.0 wt% acetone. The total flow rate of the air/acetone stream is 1.00x103 lbm/min. This stream is sent to a scrubbing system where it is mixed with water. The water entering the scrubbing unit consists of a fresh water feed and a recycled water stream coming from another unit. Two streams leave this scrubbing unit; a liquid stream containing water and acetone and a gas stream containing air, water and acetone. The gas stream leaving the scrubbing unit is discharged to the air. This gas stream contains 1.60 wt% water. The liquid stream leaving the scrubbing unit is sent to a second unit where it is heated to separate the acetone from the water. The gas stream leaving the heater contains only acetone. It also contains 99.0% of the acetone that enters the system. The water from the heater is recycled and is mixed with the fresh water to form the water feed entering the scrubber.

How much fresh water is fed to this process?
