2. In an ethanol production plant, a separator produces a 99% ethanol product from a feedstock stream containing 85% water and 15% ethanol at a rate of 450 Ib/min. The separator has two outlet streams: the ethanol product outlet stream (99% ethanol) and a residual water stream. 30% of the feedstock is bypassed and mixed with the residual water stream leaving the separator. If 60% of the ethanol entering the separator is recovered in the product stream, determine the composition of the residual water stream just after leaving the separator and the composition of the residual stream after mixing with the bypass stream.
