Product description

PRODUCTION PROCESS

Ammonium (NH4+), present in manure and digestate, is in balance with ammonia (NH3), which is volatile. Under the influence of pH and temperature, the ratio of ammonia to ammonium can be increased so that the ammonia nitrogen can volatilize more quickly. By blowing in air, the volatile ammonia is removed from the liquid fraction and the nitrogen (N) can be recovered. The air from the stripper, enriched with ammonia, is chemically bound to nitric acid in the scrubber into ammonium nitrate. The concentration of ammonium nitrate is determined by the initial amount of water in the scrubber and the amount of nitric acid added during the production process. In the Detricon process the concentration is set to 52 mass% ammonium nitrate which corresponds to 18 mass% N. After the ammonia in the scrubber is chemically bound, the ammonia-poor (<20 ppm NH3) air goes back to the stripper.

APPLICATION

Using ammonium nitrate in gardens and large scale agricultural fields enhances plant growth and provides a ready supply of nitrogen from which plants can draw.
