Ammonia Product Introduction**

Ammonia (hydrogen nitride, Andros, ammonium hydroxide) is the most important hydrogen compound of the element nitrogen, with its compounds being present in nature and also generated through the decomposition of organic materials. According to theories of scientists, ammonia and a mixture of methane gases existed in the atmosphere 4 billion years ago, during the formation of the Earth, and ammonia naturally exists in the metabolism of nucleic acids and proteins in living organisms.

Ammonia exists in both gaseous and liquid forms. Ammonia gas is lighter than air, colorless, extremely pungent, and tear-inducing, and when in contact with the respiratory system, it causes irritation and disruption, potentially harming the individual. Liquid ammonia is colorless and causes severe burns upon contact with the skin. The ammonia petrochemical unit, designed under the ICI license, has a production capacity of 1,000 tons of ammonia per day using natural gas.

Methane gas, after being pressurized in a compressor to 44 bar and hydrogenated to 3%, enters a hydrotreater. After hydrotreating, the gas directly enters zinc oxide beds. The gas passes through subsequent stages including primary, secondary, HTS, LTS, CO2 absorption section with solution, metanator, synthesis compressors, converter, and refrigeration loop, before the ammonia production is sent to the storage tanks or urea unit. This complex was established by the consortium of TOMEN and Kawasaki Japan, and Namvaran Iran, with technical know-how and engineering principles for the ammonia unit derived from Clag of England, Stamicarbon for the urea unit, and Norsk Hydro.
