Title
(EN) ONLINE MONITORING OF POLYMERIZATION INHIBITORS FOR CONTROL OF UNDESIRABLE POLYMERIZATION
(FR) SURVEILLANCE EN LIGNE D’INHIBITEURS DE POLYMÉRISATION POUR LE CONTRÔLE D’UNE POLYMÉRISATION INDÉSIRABLE
Abstract
(EN) Disclosed herein are systems and methods for monitoring and controlling a nitroxide-based polymerization inhibitor in vinyl-based monomers. A dosage of the nitroxide-based polymerization inhibitor is provided in the vinyl-based monomers. A residual concentration of the nitroxide-based polymerization inhibitor is measured substantially in real time, and an optimized dosage of the nitroxide-based polymerization inhibitor is provided in response to the measured residual concentration.
(FR) La présente invention concerne des systèmes et des procédés pour surveiller et contrôler un inhibiteur de polymérisation à base de nitroxyde dans des monomères à base de vinyle. Une dose de l’inhibiteur de polymérisation à base de nitroxyde est disposée dans les monomères à base de vinyle. Une concentration résiduelle de l’inhibiteur de polymérisation à base de nitroxyde est mesurée sensiblement en temps réel, et une dose optimisée de l’inhibiteur de polymérisation à base de nitroxyde est fournie en réponse à la concentration résiduelle mesurée.
