Haber process - Wikipedia

Jul 21, 2017· A manufacturing process creates urea fertilizer by combining ammonia gas, known as anhydrous ammonia, with carbon dioxide. High temperatures and pressure aid the chemical reaction that ultimately produces urea. The product is synthetic, but the process imitates the cycle that naturally occurs when mammals metabolize nitrogen in their bodies.

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.

Urea Production Process from Ammonia and Carbon-dioxide

Urea is manufactured by reacting ammonia and carbon dioxide in autoclave to form ammonium carbamate. The operating temperature is 135 o C and 35 atm pressure, the chemical reaction is endothermic reaction and so ammonia is maintained in excess to shift the equilibrium towards urea formation. Urea production is based on two main reactions.
