  • Application of oxygen scavengers to glycol systems
    Patent number: 9249516
    Abstract: An oxygen scavenger composition is effective in reducing oxygen-induced corrosion in aqueous systems that contain water, oxygen and a significant proportion (at least about 20 wt %) of a glycol, such as monoethylene glycol (MEG). The oxygen scavenger composition contains a sulfite, a transition metal salt, and a stabilizer to enhance the kinetics of oxygen removal (scavenging). The oxygen scavenger composition is particularly suitable when the transition metal salt component includes at least two different transition metals together, such as Ni and Co, or Ni and Mn.
    Type: Grant
