  • Method to decrease decomposition products in solutions that absorb acidic gases such as carbon dioxide and the like in the presence of oxygen
    Patent number: 8945280
    Abstract: An amine solvent solution that is useful in absorbing acid gases from a liquid or gas feed stream may have an amine additive added thereto. Additionally or alternatively, the amine additive may be added to a liquid or gas feed stream. The addition of the amine additive decreases the presence of amine-derived contaminants and/or degradation of amine in the amine solvent solution. As such, the amine solvent solution is available for effective reuse in treating the liquid or gas feed stream and there may be a decrease in the corrosion within an amine treating system.
    Type: Grant
