Problem $10$

A mixture containing benzene and toluene at $60wt\%$ and $40wt\%,$ respectively is

flowing into a separator at a rate of $1,500k\frac{g}{h}.$ Two streams are flowing out of the

separator. One of them flows at $500k\frac{g}{h}$ and in the other, $90\%$ of the benzene

contained in the feed stream is recovered. Draw the process flow sheet and determine

the mass flow rates and compositions of all streams.
