Nonlinear model based multivariable control of a debutanizer
Latin Abstract :
The debutanizer column control is a major economic incentive to a refinery due to the importance of the
product quality. The nonlinear model-based multivariable control on a debutanizer has shown to provide
improved control performance of the top product and the bottom stream qualities using a steady-state
process model with approximate dynamics. The control performance is much better than that achieved by
the traditional PID-type control system. This paper outlines the non-linear control method applied to an
industrial debutanizer and discusses the use of inferential models to predict the iso-pentane contents in the
overhead stream and the Reid vapour pressure (RVP) in the bottom stream, in nonlinear control applications.
