摘要

对反应精馏塔生产异丙醇进行了研究。首先,建立了该工艺的动态模型。然后对该过程的模型进行编程,并使用从文献中获得的基本情况对该过程进行模拟。结果表明,该馏分液中不含丙烯的异丙醇含量大于58 mol%。下一步,以冷凝器温度为约束,以高于水的冰点为条件,对一些操作变量进行优化,使馏出物中异丙醇的浓度达到最大。通过改变操作参数进行了多次模拟,最终得到馏出物中异丙醇的最佳含量在58 mol%以上。使用经典控制器的结果表明,PID控制器在冷凝器温度设定值跟踪和抗干扰方面都具有最好的性能。

Dynamic Simulation, Parameter Optimization, and Control of a Reactive Distillation Column for Production of Isopropanol via Propylene Hydration
In this study, a reactive distillation column for production of isopropanol was investigated. Firstly, a dynamic model was developed for the process. The model of the process was then programmed, and the process simulated using a base case obtained from the literature. Results showed that distillate contained more than 58 mol% propylene-free isopropanol. In the next step, optimization of some operating variables was performed to maximize concentration of isopropanol in distillate with condenser temperature as constraint, which was considered to be above the freezing point of water. Several simulations were performed by changing operating parameters, and finally optimum isopropanol content in distillate was obtained above 58 mol%. Results of using classic controllers showed that PID controller had the best performance for both condenser temperature set-point tracking and disturbance rejection.

期刊介绍: The journal provides an international forum for presentation of original papers, reviews and discussions on the latest developments in chemical and biochemical engineering. The scope of the journal is wide and no limitation except relevance to chemical and biochemical engineering is required. The criteria for the acceptance of papers are originality, quality of work and clarity of style. All papers are subject to reviewing by at least two international experts (blind peer review). The language of the journal is English. Final versions of the manuscripts are subject to metric (SI units and IUPAC recommendations) and English language reviewing. Editor and Editorial board make the final decision about acceptance of a manuscript. Page charges are excluded.
