UAN is a solution of urea and ammonium nitrate in water used as a fertilizer. The combination of urea and ammonium nitrate has an extremely low critical relative humidity (18% at 30°C) and can therefore only be used in liquid fertilizers. The most commonly used grade of these fertilizer solutions is UAN 32.0.0 (32%N) also known as UN32 or UN-32, which consists of 45% ammonium nitrate, 35% urea and only 20% water. Other grades are UAN 28, UAN 30 and UAN 18.

  • Ammoniumnitrat-Harnstoff-Lösung ist ein druckfreier, stickstoffhaltiger Flüssigdünger.
  • UAN is een geconcentreerde oplossing van ureum en ammoniumnitraat. De oplossing wordt gebruikt als vloeibare kunstmest. Het meest voorkomende type UAN is UAN 32.0.0 (32%N), welke 44.3% ammoniumnitraat, 35.4% ureum en slechts 20.4% water bevat. Andere veel voorkomende types zijn: UAN 28, UAN 30, en UAN 18. De oplossingen kunnen zeer corrosief zijn voor metalen (tot 500 MPY in geval van C1010 staal) en worden daardoor vaak behandeld met een corrosieremmer om tanks en pijpleidingen te beschermen.

Other grades are UAN 28, UAN 30 and UAN 18. The solutions are quite corrosive towards mild steel (up to 500 MPY on C1010 steel) and are therefore generally equipped with a corrosion inhibitor to protect tanks, pipelines, nozzles, etc. Urea-ammonium nitrate solutions should not be combined with calcium ammonium nitrate (CAN-17) or other solutions prepared from calcium nitrate. A thick, milky-white insoluble precipitate forms that may plug nozzles and pipelines.
