Widely used in agriculture as a nitrogen source in fertilizers, ammonia solution helps boost crop yields by providing essential nutrients for plant growth. It is a key ingredient in the production of ammonium nitrate and urea-based fertilizers. In industrial applications, it serves as a pH regulator and neutralizing agent in wastewater treatment and flue gas cleaning. It effectively removes sulfur dioxide and nitrogen oxides from exhaust streams, reducing air pollution. Ammonia solution is also used in cleaning products due to its ability to cut through grease and grime, making it common in household and industrial cleaners for glass, stainless steel, and other surfaces. In the food industry, it acts as a sanitizing agent and pH adjuster, and is used in the processing of some foods and beverages. It is also employed in refrigeration systems as a refrigerant due to its high efficiency and low environmental impact compared to synthetic refrigerants. Additionally, it plays a role in chemical manufacturing, including the production of plastics, textiles, explosives, and pharmaceuticals.
