| 摘 要： | 针对高纯乙腈连续精馏过程多塔串级及操作条件优化困难等特点,在深入分析乙腈连续精馏工艺流程及机理基础上,通过物料衡算、能量衡算、环境影响衡算和水力学分析等原理,结合必要的合理假设,建立乙腈连续精馏多塔的动态数学模型,对脱醇塔、减压塔和加压塔分别进行动态模拟和分析,考察塔内压力、加热蒸汽量等对分离过程的影响,并进一步寻找这些因素对出料乙腈的动态变化数据,为实施系统的集成优化与控制提供了良好基础.

| Abstract: | Based on the deep analysis of continuous process of rectifying high purity acetonitrile and its mechanics,with rational assumptions dynamic mathematical models of multi-tower for rectifying high purity acetonitrile were established by material balance,energy balance,environmental impact and hydraulic analysis,considering the character of multi-stage cascade and the difficulty of operating conditions optimization.Furthermore,the dynamic simulation and analysis were carried out respectively to the dealcoholization tower,vacuum tower and pressure tower.Simultaneously,investigating the tower pressure and steam heating effect on the separation process,and finding the further relative dynamic data of acetonitrile could provide a good foundation for the research of system integration optimization and control. |
