Abstract

Decentralized control of an ideal hypothetical ternary reactive distillation column with an inert component is explored. Both composition measurement based and temperature inferential control structures are designed using simple heuristic approaches (two and three-point). The three-point composition control structure is proposed for the example RD column for the first time in this work. Although stable closed loop responses are seen for the throughput changes for all, the two-point structures have failed to achieve tight control of the product purity in the bottoms or purity of inert in the distillate for the inert composition changes due to fixed reflux ratio. The performances of the three-point control structures for the inert composition changes are quite satisfactory due to the indirect manipulation of the reflux ratio. The independent manipulation of the reflux rate and distillate (instead of fixed reflux ratio policy) is an important control decision for the successful regulation of the example RD column.

带惰性的理想三元反应蒸馏塔的分散控制

本文探讨了对带有惰性组分的理想假想三元反应蒸馏塔的分散控制。采用简单的启发式方法（两点和三点）设计了基于成分测量和温度推断的控制结构。本研究首次针对示例 RD 精馏塔提出了三点成分控制结构。虽然在所有的吞吐量变化中都能看到稳定的闭环响应，但在固定回流比导致的惰性成分变化中，两点式结构无法实现对底部产品纯度或馏分中惰性纯度的严格控制。三点控制结构由于可以间接控制回流比，因此在惰性成分变化方面的性能相当令人满意。独立控制回流速率和馏分（而不是固定回流比政策）是成功调节示例 RD 塔的重要控制决策。
