Advanced oxidation of kinetic hydrate inhibitors

摘要

Advanced oxidation process namely ozonation and Fenton's (hydrogen peroxide/Fe:²⁺) were utilized to degrade kinetic hydrate inhibitor (KHI). The oxidized solution after scavenging oxygen can be successfully disposed to the injection well. This facilitates use of KHI more frequently and in higher concentrations for future projects oil & gas operations. It also offers an alternative that competes efficiently with thermodynamic hydrate inhibitor (THI) or complements THI.
