Urea manufacturing - Yara United States

Urea is a hot concentrated solution produced by the reaction of ammonia with carbon dioxide. When dissolved with water, this concentrated urea hot-melt liquid becomes an aqueous urea solution or a feedstock for the prilling or granulating process. Prilled urea is used for the technical grade urea market for industrial applications.
