| Abstract: | The recovery of Dimethylbenzene and Butylacetate from industry spent solvent oil by batch distillation was studied, and the batch distillation experiment was performed with pretreated material. The effect of separation temperature, time and reflux ratio on separation process was investigated. The experimental results showed in the optimum conditions that the concentrations of Dimethylbenzene and Butylaeetate were above 95 ; in top distillate product, and the yield of Dimethylbenzene and Butylaeetate was 62; and 99.4; ,respectively. The results showed with Aspen Plus simulation that Dimethylbenzene and Butylaeetate from spent solvent oil could be separated efficiently with distillation technique. |
