Asteady state and continuous separator has a total feed rate of 100. kg/h of a 55.0 wt. % benzene mixture. the balance is toluene (i. e., 45 wt. % toluene). a vapor stream leaves the process and has a benzene concentration of 85.0% by mass and a liquid stream leaving the process has a benzene concentration of 10.6% by mass. a. draw and label the process flow chart. develop a consistent variable naming system. b. simplify the general balance equation. c. write and solve the total mass balance and the benzene mass balance.
