A saturated liquid mixture containing 60 mol% benzene and 40 mol% toluene is to be distilled to produce a saturated liquid distillate of 95% benzene and a bottom product of 90% toluene.
calculate
a. the pressure of the condenser when the temperature of a total condenser is at 90oC.
b. the temperature of the reboiler, allowing a 0.15 atm condenser pressure drop and a 0.35 atm pressure drop through the column.
c. the average relative volatility of this column.
