Abstract:
Methods and compositions for inhibiting corrosion of a corrodible metal surface that contact a nitrogen-containing solution. The method comprises adding a chemical treatment composition to the nitrogen-containing solution that includes an organic filmer and a passivator. The organic filmer may be a hydroxycarboxylic acid. The chemical treatment composition may further include a surface-active compound.
