乙酸乙酯废水处理工艺模拟与优化

Simulation and Optimization of Ethyl acetate Wastewater Treatment Technology

运用Aspen Plus11.1对乙酸乙酯和乙醇混合物提纯乙酸乙酯的精馏过程进行了优化,得到如下结论:进料位置为第8块塔板,且在常温常压下进料时,乙酸乙酯回收效果最好,此时流股2的乙酸乙酯质量分数为70.3%。

Through optimizing the distillation process of purifying the mixture of ethyl acetate and ethyl alcohol by Aspen Plus 11.1, the obtained conclusions are when the feed stage is eighth, feeding is at atmospheric temperature and ordinary pressure, the recycle effect of ethyl acetate is the best, and in the above conditions, the mass of ethyl acetate in the stream2 reaches 70.3%.
