Dissolve oxygen (related to oxygen solubility) can promote oxidative degradation of amine solvent. A few additives have been investigated including non-ionic surfactant, Xiameter™, 2-mercaptobenzothiazole, and sodium metavanadate. The influence of adding these additives on dissolve oxygen was reported, and the results and discussion is available in section 3.3.1 of the reference (related to Figures 5, 6 7 and 8).
