Ammonia-based refrigeration systems are widely used in industrial refrigeration applications, including in food processing and cold storage facilities. The textile and dye industries also rely heavily on ammonia, particularly for producing synthetic fibers and in dyeing processes. Ammonia is used in the production of nylon, spandex, and other synthetic fibers, contributing to the growing textile and apparel market. In pharmaceuticals, ammonia is used in the production of various active ingredients and as a base for certain drug formulations. Additionally, ammonia has applications in water treatment, where it is used in the treatment of wastewater, especially in removing impurities and reducing the presence of harmful compounds. Other smaller yet significant uses of ammonia include its application in the production of cleaning agents, leather tanning, and in the food industry for specific processes.
Agriculture remains the largest consumer of ammonia, with over 70% of global ammonia production used in the creation of nitrogen-based fertilizers. These fertilizers, including urea, ammonium nitrate, and ammonium sulfate, are critical to enhancing soil fertility and increasing crop yields to meet the needs of a growing global population. As such, ammonia plays a vital role in ensuring food security worldwide, especially in regions with intensive farming practices. In chemical manufacturing, ammonia serves as a key raw material for producing a variety of industrial chemicals, including nitric acid, which is used in the production of explosives, synthetic fibers, and plastics. Ammonia also plays a crucial role in producing hydrogen, acrylonitrile, and other compounds essential to industries ranging from automotive to textiles. In the food and beverage industry, ammonia is utilized in the refrigeration and cooling systems of food processing plants and storage facilities, as it is a highly efficient and cost-effective refrigerant. Ammonia-based refrigeration systems are considered more environmentally friendly compared to traditional synthetic refrigerants, offering lower global warming potential. The wastewater treatment industry also consumes significant amounts of ammonia, where it is used in the treatment of both municipal and industrial wastewater. Ammonia-based compounds are essential in removing harmful pollutants and controlling nitrogen levels in water systems, thereby contributing to environmental protection efforts and improving water quality. Other smaller, but important applications for ammonia include its use in the production of cleaning agents, textiles, pharmaceuticals, and as a fuel in certain industrial processes. The diverse and widespread applications of ammonia across these sectors contribute to its ongoing global demand, while the growing focus on sustainable production methods is likely to shape the future dynamics of the market.
Anhydrous ammonia, which is ammonia in its pure, gas form without water content, dominates the ammonia market, particularly in agricultural applications. It is widely used as a fertilizer in the form of a soil amendment, providing a highly concentrated source of nitrogen, essential for plant growth. Anhydrous ammonia is typically applied directly to soil in its gas form or as a component in other nitrogen-based fertilizers, such as ammonium nitrate and urea. Its high nitrogen content and cost-effectiveness make it a preferred choice for large-scale farming operations, especially in regions with significant agricultural demand, like North America, Asia-Pacific, and Latin America. Beyond agriculture, anhydrous ammonia is used in the chemical industry for producing various chemicals like nitric acid, which serves as a precursor for explosives, synthetic fibers, and other industrial chemicals. On the other hand, aqueous ammonia, which is ammonia dissolved in water to form a solution, is increasingly used in a range of industrial applications, including in the food and beverage industry for refrigeration and in wastewater treatment. Aqueous ammonia is favored for its lower volatility compared to anhydrous ammonia, making it safer and easier to handle in certain applications. It is commonly employed in smaller-scale agricultural settings for fertigation, where it is applied through irrigation systems, as well as in industrial processes such as the production of cleaning agents and in certain chemical manufacturing applications.
