Apr 28, 2010· Urea Production and Manufacturing Process. Urea was first produced industrially by the hydration of calcium cyanamide but the easy availability of ammonia led to the development of ammonia/carbon dioxide technology. This is a two step process where the ammonia and carbon dioxide react to form ammonium carbamate which is then dehydrated to urea.
