TUNGSTATE BASED CORROSION INHIBITORS |
摘要 |
A trace amount of a tungstate added together with an ortho-phosphate and/or phosphonite is disclosed for inhibiting corrosion by a nitrogen fertilizer solution. In particular, an ammonium nitrate fertilizer solution is in contact with ferrous metal storage tanks, piping, and equipment surfaces. Tungstate added with an iron stabilizer including a dispersant polymer is also effective for inhibiting corrosion.
