A liquid mixture of benzene and toluene contains 50.0% benzene by mass. The mixture is to be partially evaporated to yield a vapor containing 82.5% benzene and a residual liquid containing 12.0% benzene by mass. The process is carried out continuously and at steady-state. No reactions occur in the separator. The feed enters the separator at a rate of 100.0kg/h. Begin your analysis by drawing and labeling a flow sheet of the process and identifying all unknowns. How many independent balances may be written for the system? Solve for the liquid (L) and vapor ( V) flow rates leaving the separator. V=L=kg/hkg/h
