Urea Prilled contains 46% urea nitrogen. Prilled Urea is a white, free flowing prilled (spherical) solid with a small amount of organic material as a conditioner or anti-caking agent manufactured by the reaction of Ammonia and Carbon Dioxide. Concentrations of Biuret in Prilled Urea are less than 0.5%.
Urea Prilled plays an important role in many industries, including:
Snow Melt
Prilled urea is an easy, convenient way to melt snow and ice on roads, runways, and other surfaces. It's made by spraying anhydrous ammonia into a bed of urea crystals. The ammonia dissolves the urea, creating a slurry that can be sprayed or spread onto the ground. When it dries, the prills (small pellets) are left behind and can be used as needed.
Prilled urea melts snow and ice in two ways:
- It lowers the temperature at which snow melts from 32°F to 0°F (0°C to -18°C). The coldest temperature at which snow will freeze is 32°F (-17°C), so if the temperature drops below this point, the prills will start to melt the snow on contact.
- The prills release ammonia gas when they come into contact with water. Ammonia gas lowers the freezing point of water down to about -33°F (-36°C).
Cattle Feed
Prilled urea is used in cattle feed as a source of nitrogen. This means it can help increase the amount of protein in a cattle's diet. It also helps to ensure that cattle have an adequate supply of amino acids, which are essential for healthy development.
