Anhydrous Ammonia
Description
Anhydrous Ammonia is a gas containing approximately 82% nitrogen. Under low temperature (around -33°C), Anhydrous Ammonia converts into a liquid and is stored and transported in this form. Ammonia is the main raw material for the production of urea, and is used as one of the raw materials for the manufacture of several other fertilizer products including DAP, NP/NPK, ammonium nitrate, calcium ammonium nitrate, ammonium sulphate and nitrogen
solutions. Ammonia can be applied directly to the soil, thus providing high nitrogen content. Ammonia is also important as it is used for a number of industrial applications, such as caprolactum, acrylonitrile, melamine, explosives and glue.
