Corrosion inhibitor for nitrogen fertilizer solutions |
摘要 |
A trace amount of a molybdate is disclosed for inhibiting corrosion by concentrated urea-ammonium nitrate fertilizer solutions (UAN) in contact with ferrous metal piping and equipment surfaces. From 10 to 200 ppm of sodium molybdate are blended in a UAN solution containing 20-50 weight percent water for effectively inhibiting corrosion. The corrosion-inhibited UAN solution is non-sludging, non-foaming and essentially free of precipitates.
