Abstract

Abstract:

The distillation column with side reactors (SRC) process allowing a more flexible way of coupling reaction and separation leads to the increase in the freedom of the system and the number of design variables, which consequently increases the difficulty in the process simulation, optimization and dynamic control. For smooth operation and automatic control of the SRC process, with the SRC integration technique in the production of methyl acetate production process as an example, the steady-state optimization, dynamic control and simulation are discussed in the paper. To obtain the optimum integrated structure and the steady-state simulation of SRC for methyl acetate production, the systematic design approach based on the concept of independent reaction amount is applied to the process of SRC for methyl acetate production. Then multivariable control schemes based on product quality control with variable ratio control are designed and SRC of methyl acetate dynamic simulation based on process simulation software Aspen is used to verify the effectiveness of the control scheme. The simulation results show good control precision, robustness and dynamic follow performance of the control scheme.

Key words: methyl acetate, distillation column with side reactors, steady-state simulation, dynamic control

摘要：

侧反应器与精馏塔的耦合结构与物料交换方式的灵活性,造成系统的自由度高、设计变量多,增加了该过程的稳态优化模拟和动态控制的难度。针对侧反应精馏过程(SRC)的平滑操作和自动控制问题,以醋酸甲酯工业生产过程为例,采用基于独立反应量的稳态设计方法获取最佳的反应精馏集成结构和操作参数,在此基础上设计了以产品成分调节变比值控制为主的多变量控制方案,并通过在Aspen流程模拟软件建立醋酸甲酯侧反应精馏动态流程模拟系统,验证控制方案的有效性。
