摘　　要：甲基异丙基酮生产中,水与甲基异丙基酮等形成共沸物,文中运用剩余曲线图(RCM)方法对甲基异丙基酮分离过程进行分析研究,根据非均相共沸精馏原理,提出了在丙酮塔中增加油水分离器的方法脱除待分离物系中的水,从而达到节能的目的。文章在Aspen Plus中建立了该节能型甲基异丙基酮分离过程的模拟模型,进行了计算和分析,并加以实验验证,二者比较吻合。结果表明,该分离工艺即节省了设备投资,又降低了分离能耗,并且提高了脱水效率,改善了产品质量,同时还提高了产品收率,所用方法对简化工艺流程起到了积极作用。Methyl-isopropyl-ketone separation process was studied with residue curve maps （RCM）, and new dehydration method of methyl-isopropyl-ketone separation process based on heterogeneous azeotropic distillation was proposed to save energy by placing decanter in the middle of acetone distillation column. Simulation model of the energy-saving methyl-isopropyl-ketone separation process was set up in Aspen Plus. The simulation result was analyzed, and experiments were implemented to test the process, both of which are in agreement. The results show that the new process not only reduces the investment of equipment needed by dehydration in old process, but also reduces the separation energy consumption, improves the dehydration efficiency and product quality, increases the product yield. The method presented plays a good effect on simplifying process flow.
