摘要
为了对含有少量乙酸乙酯和乙醇的有机废水进行有效净化回收,提出非均相共沸精馏三塔-层析分离工艺,并基于Aspen Plus的概念设计对该方案进行了可行性验证,通过考察粗馏塔、脱醇塔和酯精制塔的工艺参数对分离效果的影响,得到了最佳工艺操作条件。模拟结果表明,该工艺可达到分离要求,具有工艺简单、能耗低、易操作的特点。
In order to purify and recycle organic wastewater containing a small amount of ethyl acetate and ethanol effectively,heterogeneous azeotropic distillation three towers-decanter separation process is proposed. The feasibility is verified based on the conceptual design of Aspen Plus. Various process parameters of crude distillation tower, dealcoholization tower and ester refining tower are investigated to obtain the optimum operating conditions. The results show the process can achieve the separation specification and has the characteristics of simplicity, low energy consumption and easily operation.
