| Abstract: | Using CaCl2/C2H6O2 as extractant,and Wilson as thermodynamic equation,Aspen Plus was used to simulate the extractive distillation separation of ethanol water system with salt.The optimal operation parameters of the two columns were obtained.Under the optimal conditions,the purity of ethanol at the top of T1 column is 99.97%,and the purity of water at the top of T2 column is 99.95%.During the whole separation process,the recovery rate of ethanol is as high as 99.99%. |
