A novel cyclohexanone distillation process using dividing wall column(DWC)is proposed in order to reduce energy consumption,reduce equipment investment and improve effectively the operation efficiency of the cyclohexanone unit.The influences of operating parameters such as distribution position of dividing wall panels,gas-liquid distribution,and reflux ratio are analyzed,and the design parameters are further optimized for dividing wall column.On this basis,two solutions are compared.The results show that the novel distillation process can save energy by 15.9％,with certain advantages in industrial application.
