A mixture of 620 lbmol/h of 36 mol% benzene and the remainder toluene is separated continuously into two products. One product i
Licemer1 [7]

Answer:

P_1=206.7lbmol/h\\\\P_2=413.3lbmol/h

Explanation:

Hello!

In this case, for the separation of the benzene-toluene mixture, we can use the following mole balances including the given mole fraction at each stream per species:

B:0.36*620=0.98P_1+0.05P_2\\\\T:0.64*620=0.02P_1+0.95P_2

That can be solved by using a solver for P1 (benzene-rich flow) and P2 (toluene-rich flow):

P_1=206.7lbmol/h\\\\P_2=413.3lbmol/h

Best regards!
