Control properties of thermally coupled distillation sequences for different operating conditions

The understanding of the dynamic behavior of distillation columns has received considerable attention due to the fact that distillation is one of the ost widely used unit operations in chemical process industries. Thermally coupled distillation sequences (TCDS) can provide significant energy avings with respect to the operation of sequences based on conventional distillation columns. TCDS exhib...

Study of Control Properties of Intensified Thermally Coupled Distillation Sequences

In this work, we analyze the control properties of thermally coupled reactive distillation sequences and thermally coupled extractive distillation sequences in comparison with conventional reactive and extractive distillation configurations. All sequences have been designed using a multi objective genetic algorithm with restrictions. We study the theoretical control properties of those schemes ...

Control Properties of Thermally Coupled Extractive Distillation Sequences

The structure of the thermally coupled distillation systems offers some control challenges arising from the transfer of vapor (or liquid) streams between the columns. In particular, the presence of recycle streams for coupled schemes has influenced the notion that control problems might be expected during the operation of those systems with respect to the rather well-known behavior of conventio...

Control Behaviour of Thermally Coupled Distillation Sequences

T he controllability properties of thermally coupled distillation sequences for the separation of ternary mixtures are compared with those of the conventional direct and indirect sequences. Closed loop responses to set point changes were performed, and controllers were tuned to minimize their ISE values. The results indicate that the integrated systems exhibit better control properties than seq...

Control Performance of Thermally Coupled Distillation Sequences with Unidirectional Flows

The Petlyuk distillation system has been considered with special interest in the field of separation processes because of the high energy savings that it can provide with respect to the operation of sequences based on conventional columns. The original design of the Petlyuk structure, however, shows two interconnections that seem to affect its operational and controllability properties. For one...
