SENSORS: In-Line Monitoring of Vinyl Chloride Suspension Polymerization with Near Infrared Spectroscopy, 2 - Design of an Advanced Control Strategy
João Miguel de Faria Jr., Fabricio Machado, Enrique Luis Lima, José Carlos Pinto*
Near infrared spectroscopy (NIRS) is used for in-line monitoring of particle morphology in PVC suspension polymerizations. Calibration models are used as references for control. As modification of operation variables during the batch leads to modification of the final morphological properties of the powder, advanced NIR-based control procedures can be implemented for control of morphological properties of PVC resins, as illustrated through simulation.
