摘要/Abstract

摘要： 反应精馏技术是将反应和精馏两个单元操作耦合在一个设备中同时进行,其非线性给反应精馏过程的平稳操作和过程控制提出了更高的要求。目前,反应精馏过程控制研究都是针对特定反应体系进行的有针对性的研究,对于乙酸戊酯反应体系的控制研究少有报道。本文利用Aspen Plus和Aspen Dynamic 软件对乙酸戊酯的反应精馏过程进行动态模拟,针对塔釜产品组成要求提出温度控制和组成控制两种不同的控制方案,对两个控制系统分别进行±10%的进料流量扰动测试和酸醇比为1:1、1.2:1的进料组成扰动测试。研究了不同扰动对产品质量的影响并比较了两种方案在不同扰动干扰下的控制效果。结果表明:进料组成扰动会对两个控制方案造成较大影响;温度控制方案的控制稳定性要好于组成控制方案。

Abstract: Reactive distillation (RD),combining reaction with separation in a single process unit,has received significant attention. However,due to non-linear coupling of reaction and separation,steady operation and process control are more demanding. At present,the research of control method for the reactive distillation was focused on the designated reactive system. And amyl acetate reactive system has almost not been reported. In this paper,the RD dynamic simulation of amyl acetate was studied with Aspen Plus and Aspen Dynamic. Temperature control method and composition control method were proposed so that the operation results of RD satisfied the production demand. Feed flow rate and feed composition were regarded as two disturbances to test the control methods. The impact of different disturbances on product composition was studied and the control effects of two methods were compared when facing different disturbances. The simulated results showed that feed composition had greater influence on the control and the temperature control method was more stable than the composition control method.
