A distillation column is separating a 30% Benzene, 70 % Toluene. The feed rate is 237 kmol/h and is a saturated liquid. The column has a partial reboiler and a partial condenser. We desire distillate mole fraction of 95% and a bottom mole fraction of 2.5%. Assume constant molar overflow condition (CMO) is valid. Use the benzene toluene data.
