Dynamic Analysis Of Distillation Sequences With Thermal Coupling (With Unidirectional Flows) For The Separation Of Ternary Mixtures, Juan Gabriel Segovia-Hernández, Adrian Bonilla-Petriciolet, Luis I. Salcedo-Estrada

Adrian Bonilla-Petriciolet

The Petlyuk distillation system has been considered with special interest because of the high energy savings 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. To overcome this problem, two alternate structures have been suggested that use unidirectional flows of the vapor or liquid interconnecting streams. In this work, a comparative analysis of the control properties of the Petlyuk column and the alternate arrangements with unidirectional interconnecting flows is presented. Through a singular value decomposition …
