摘要

研究了间歇精馏从工业废溶剂油中回收二甲苯和乙酸丁酯的工艺，并对预处理后的物料进行了间歇精馏试验。考察了分离温度、时间和回流比对分离过程的影响。实验结果表明，在适宜的条件下，顶馏产物中二甲苯和乙酸丁酯的浓度均在95%以上，二甲苯和乙酸丁酯的收率分别为62%和99.45%。在质量平衡和相对挥发性的基础上，建立了一个稳健、快速的数学模型。所得结果令人满意，可用于间歇精馏的实时控制和管理。

Recovery of Dimethylbenzene/ Butylacetate from Spent Solvent Oil by Batch Distillation: Experiment and Simulation

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 that the concentrations of Dimethylbenzene and Butylacetate were above 95% in top distillate product, and the yield of Dimethylbenzene and Butylacetate was 62% and 99.45%,respectively,under appropriately conditions. A robust and rapid mathematical model had been developed, based on mass balance and relative volatility. The satisfactory results obtained allowed to use the model in real time for a better control and management of batch distillation.
