How urea is made
Industrial urea is made from natural gas and air that are compressed under high temperature (210°C ). Several chemical reactions occur, resulting in a mixture of ammonia, ammonium carbonate and urea. This mixture is dehydrated to form urea in a crystal or powdered form. The powder and crystals can be melted and made into prills, which is the common form for urea distribution.
