Better dynamic control of the temperature in an exothermic chemical reactor allows increasing the injection of reactants
After a feasibility study, Repsol YPF decided to apply a model-based predictive controller to a batch reactor producing polyols. The predictive controller for reactors (PCR) is a set of control modules that are designed to face most of the reactor configurations. The important increase of production is a consequence of the better handling of the reactor temperature. Here's a description of the unit and control objectives, methodology, project steps, results and the corresponding benefits.
Process description and specifications. The Chemicals Division of Repsol YPF operates a large petrochemical complex in Tarragona, Spain. Among the plants of the facility, a polyols reactor (Fig. 1) ha
