Multivariable Predictive Control of Atmospheric Distillation

Aiming at two sets of crude distillation unit—atmospheric distillation column of Lanzhou petrochemical plant and employing an advanced multivariable predictive controller,the product quality control and real time optimum control are achieved.The field operation of this controller shows that multivariable predictive controller IDCOM can successfully solve the difficult problems of control application such as strong interrelationship between the long time delay and the multiple variables of the process model.
