文摘This paper proposes a modified operation mode of batch extractive distillation with two reboilers. The seoaration 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 tile.modified mode over the regular mode such as easier operation control, more flexibility and higher separation efficiency etc. So it suppues certain guidance for the industrial application of batch extractive distillation process.
