Ammonia is widely used across industries, with its most significant application being in agriculture as a critical component of nitrogen fertilizers, such as ammonium nitrate, ammonium sulfate, and urea, which are essential for crop growth and food production[1][3][6]. About 90% of all ammonia produced is used for this purpose[3].
In industrial settings, ammonia is employed in several key ways:
- Industrial Refrigeration: Ammonia is a highly efficient and cost-effective refrigerant, widely used in food processing plants, cold storage warehouses, and various beverage industries due to its high cooling capacity. However, its toxicity requires stringent safety measures[1][6][8].
- Cleaning Products: Ammonia is a common ingredient in household and industrial cleaning agents, such as window cleaners and degreasers, for effectively breaking down fats and oils[1][7].
- Chemical Manufacturing: It serves as a precursor for the production of numerous chemicals, including explosives, plastics, and synthetic fibres such as nylon and rayon[1][6][7].
- Metal Treating: Ammonia is used in heat treating, annealing, sintering, and brazing metals. It helps create reducing atmospheres, which prevent oxidation and improve the quality and durability of metals[5][6][7].
- Petroleum and Gas Industry: Ammonia is used to neutralize acidic constituents and in selective catalytic reduction (SCR) technology to reduce NOx emissions from exhaust gases[1][6].
- Mining: Ammonia is involved in the extraction of metals such as copper, nickel, and molybdenum from their ores[4].
Other notable uses include:
- Food Production: Ammonia acts as a leavening agent, acidity regulator, and is involved in caramel coloring and cheese production processes[5][7].
- Water Treatment: Utilized in wastewater treatment to neutralize acids and control pH[3][6].
- Textile Industry: Employed in dyeing, scouring, and the manufacture of synthetic fibres[6].
- Pharmaceuticals: Used in the crystallisation and formulation of liquid drugs into tablet or powder form[6].
- Fermentation: Provides nitrogen for microorganisms and adjusts pH levels during industrial fermentation processes[2][3].
