A mixture of 620 lbmol/h of 36 mol% benzene and the remainder toluene is separated continuously into two products. One product is 98 mol% benzene and the other is 95 mol% toluene. Calculate the flow rates of both products in kmol/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:

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

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
