Abstract
Distillation columns constitute one of the most important processes in the Chemical Industry, in which the implementation of advanced control techniques is an indispensable effort. Dynamic models of distillation columns are among the most complex found in process control systems. This requires the identification of suitable models, then, many difficulties arise due to the complexity of these processes. This work presents a parametric identification of a debutanizer column by a multivariable model, with two inputs and two outputs, using a NARMAX polynomial model, which serves for application in control.
