A liquid mixture of benzene and toluene contains 60% benzene by mass. The mixture is to be partially evaporated to yield a vapor containing 85% benzene and a residual liquid containing 20% benzene by mass. The process is carried out continuously and at a steady state. No reactions occur in the separator. The feed enters the separator at a rate of 100 kg/h. (a) Begin your analysis by drawing and labeling a flow sheet of the process and identifying all unknowns. (b) How many independent balances may be written for the system? (c) Solve for the liquid (kg/h) and vapor (kg/h) flow rates leaving the separator.
