A distillation column contains a mixture of 60% benzene and 40% toluene, by mass, at 1 atm pressure. will be used to separate benzene from the mixture. The feed rate is 20000 kg/h. supply temperature is 298 K. The distillate desired composition is 96% mol% and the subproduct is 5% mole benzene. The reflux rate is taken as 2 times the minimum reflux rate and the reflux the stream is returned to the column as a saturated liquid. a constant relative volatility 2.54 for benzene-toluene is acceptable.
