Latest Patents
One of Cringle's latest patents is titled "Method for maintaining effective corrosion inhibition in gas scrubbing." This patent describes a technique for maintaining copper ions in the plus 2 oxidation state, which serves as an inhibitor in an alkanolamine gas conditioning absorbent solution. This method provides corrosion protection for metals in contact with the alkanolamine solution. The procedure involves applying an induced or impressed voltage across points in the circulating copper-containing solution, particularly when recovering CO₂ from flue gas in the presence of oxygen.
Another significant patent is "Bismuth inhibitors for acid gas conditioning solutions." This invention presents a corrosion-inhibited composition that includes an aqueous gas conditioning solution, such as an alkanolamine, combined with small amounts of soluble trivalent bismuth compounds. These compositions are designed to separate acid gases like carbon dioxide from feed streams in gas conditioning apparatus while minimizing corrosion of stainless steel components.
