Abstract
A thermally coupled distillation technology can bring energy-saving benefits, but it poses challenges to process control. This article explores dynamic control of different side-stream quaternary extractive distillation configurations. One the one hand, the open-loop controllability of these processes is analyzed in terms of various criteria by the control design interface technology of Aspen Plus Dynamics. On the other hand, their control structures are established and examined by introducing large feed flow and composition perturbations. The results show that the triple-side-stream distillation still performs the best state and input–output controllability in spite of the strongest nonlinearity, and is also well resistant to large feed perturbations using a simple control structure.
热耦合精馏技术可以带来节能效益，但也给工艺控制带来了挑战。本文探讨了不同侧流四级萃取精馏配置的动态控制。一方面，通过 Aspen Plus Dynamics 的控制设计界面技术，根据各种标准分析了这些过程的开环可控性。另一方面，通过引入大的进料流量和成分扰动，建立并检验了它们的控制结构。结果表明，尽管非线性最强，三侧流蒸馏仍然具有最佳的状态和输入输出可控性，而且使用简单的控制结构也能很好地抵抗大的进料扰动。
