A fresh feed stream that is 37 mol% acetone and the balance benzene enter a separation process at 1700 mol/hr. Three streams exit the separator. A product stream contains 95% of the acetone that enters the separator and is 99 wt% acetone and the balance benzene. A waste stream contains the remaining acetone and benzene. The separator can only process streams that contain 10 wt% or less of acetone. Therefore, a third stream of pure water is continuously recycled from the separator and mixed with the fresh feed prior to entering the separation process. Draw a flowchart of the process. Clearly state any assumptions What is the mass flow rate of the recycle stream? c. What is the mass fraction of acetone in the waste stream?
