  • Online monitoring of polymerization inhibitors for control of undesirable polymerization
    Patent number: 9656930
    Abstract: 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.
    Type: Grant
    Filed: January 12, 2016
    Date of Patent: May 23, 2017
    Assignee: ECOLAB USA INC.
    Inventors: Ramon Colorado, Jr., Vincent E. Lewis, Robert A. Geiger, Jessica M. Hancock, Andrew R. Neilson
