1. The product of a fermentation reactor contains ethanol with a mass fraction of 0.08. You want to distill this product in order to make a product in such manner that the distillate should have 50% (mass basis) alcohol. The residue left in the distiller contains 3% alcohol a) Draw a flow chart for the process providing known values and unknown variables. b) How many degrees of freedom does the system have? c) Assuming as basis of calculation 1 Kg of the fermented material. What mass of distillate can you obtain under these conditions?
