Question

A liquid mixture of benzene and toluene contains 55.0% benzene by mass. The
mixture is to be partially evaporated to yield a vapor containing 85.0% benzene and a
residual liquid containing 10.6% benzene by mass.

Suppose the process is to be carried out continuously and at steady state, with a feed
rate of 100.0 kg/h of the 55% mixture. Let mv (kg/h) and (kg/h) be the mass flow
rates of the vapor and liquidproduct streams, respectively.

Draw and label a process flowchart, then write and solve balances on total mass and
on benzene to determine the expected values of mv and m1

For each balance you have discarded some terms explain why and which terms you
have discarded
