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 and  ̇ ml be the mass flow rates (in kg/h) of the vapor and liquid product streams, respectively, draw and label a process flow chart for this process.

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 and  ̇ ml be the mass flow rates (in kg/h) of
the vapor and liquid product streams, respectively, draw and label a process
flow chart for this process.
