| 摘 要： | This paper proposes a modified operation mode of batch extractive distillation with two reboilers.The separation of ethanol and water using as ethylene glycol is well done to validate the feasibility of this mode.The pilot-plant experimental data under the identical operational conditions between the regular mode and the modified mode are in particular discussed.The studied results prove more practical advantages of the modified mode over the regular mode such as easier operation control,more flexibility and higher separation efficiency etc.So it supplies certain guidance for the industrial application of batch extractive distillation process.
