Ammonium nitrate is an important fertilizer with NPK rating 34-0-0 (34% nitrogen). [17] It is less concentrated than urea (46-0-0), giving ammonium nitrate a slight transportation disadvantage. Ammonium nitrate's advantage over urea is that it is more stable and does not rapidly lose nitrogen to the atmosphere.
Urea (CO(NH 2) 2), with 45-46% nitrogen, another popular source of nitrogen, having the advantage that it is solid and non-explosive, unlike ammonia and ammonium nitrate. Calcium ammonium nitrate Is a blend of 20-30% limestone CaCO 3 or dolomite (Ca,Mg)CO 3 and 70-80% ammonium nitrate with 24-28 % nitrogen.
Prilled is a term used in mining and manufacturing to refer to a product that has been pelletized. ANFO explosive typically comprises ammonium nitrate prills mixed with #2 fuel oil. [2] The pellets are a neater, simpler form for handling, with reduced dust.
Nitrogen fertilizers and synthetic products, such as urea and ammonium nitrate, are mainstays of industrial agriculture, and are essential to the nourishment of at least two billion people. [10] [13] Industrial facilities using the Haber process and its analogues have a significant ecological impact. Half of the nitrogen in the great quantities ...
In its natural state, nitrogen exists primarily as a gas (N2) in the atmosphere, making up about 78% of the air we breathe. Nitrogen finds extensive usage across various sectors, primarily in the agriculture industry, and transportation. Its versatility stems from its ability to form numerous compounds, each with unique properties and applications.
The effectiveness of the water gels is dependent on the dissemination of salts in the salt solution. The particles need to be very small and fine so that they can be dispersed well throughout the solution. Some salts that are commonly used include: ammonium nitrate, sodium nitrate, sodium perchlorate and potassium chlorate.
In response to changes in mining technology, the product line expanded to include blasting agents based on ammonium nitrate and nitric acid in the 1940s. [7] Ammonium nitrate was produced from anhydrous ammonia and air (the DuPont process) beginning in the 1950s. [7] The original nitroglycerine-based products were phased out by 1983. [2]
The ammonia is used mainly as a nitrogen fertilizer as ammonia itself, in the form of ammonium nitrate, and as urea. The Haber process consumes 3–5% of the world's natural gas production (around 1–2% of the world's energy supply).
