Chemistry | Urea and ammonium nitrate | Highest quality - maximum output
Nitrate-based fertilizers are the most commonly used straight fertilizers accounting for millions of tons of products per year such as urea and ammonium nitrate. Measuring the concentration of urea and ammonium nitrate optimizes the output and ensures highest quality of the final products.
Ammonium nitrate has the chemical formula NH₄NO₃. Produced as small porous pellets, or “prills”, it’s one of the world’s most widely used fertilizers. It is also the main component in many types of mining explosives, where it’s mixed with fuel oil and detonated by an explosive charge.
Urea has the chemical formula (NH2)2CO. It is an important raw material for the chemical industry - widely used in NOx control systems to reduce nitrogen oxides emissions. With SNCR (selective non-catalytic reduction) systems, urea is often the reagent choice for safety reasons. Urea is stable, non-volatile, non-explosive and non-flammable.
Both urea and ammonium nitrate can be further concentrated and converted into a solid form (granules).
Anton Paar’s inline refractometer L-Rix 5100 has proven to be well suited for the continuous concentration monitoring of urea and ammonium nitrate.
