How to produce urea fertilizer is one of the most important topics in modern fertilizer manufacturing because urea remains one of the most widely used nitrogen fertilizers in global agriculture. Its high nitrogen content, cost efficiency, and strong crop performance make it an essential fertilizer for cereals, vegetables, fruits, and commercial farming systems. As agricultural demand continues to grow, many fertilizer manufacturers focus on improving production efficiency and developing reliable urea fertilizer systems for large-scale agriculture.
Modern urea fertilizer production requires more than simple chemical processing. Manufacturers must carefully manage raw material quality, nitrogen concentration, production stability, and formulation consistency to create fertilizers that deliver effective agricultural performance. Understanding the manufacturing process is essential for companies looking to develop commercial fertilizer products for modern farming applications.

RAW MATERIALS REQUIRED
-
Ammonia (NH₃)
-
Carbon dioxide (CO₂) (by-product of ammonia production)
-
Process water
-
Additives (anti-caking agents, formaldehyde – optional)
CHEMICAL REACTIONS INVOLVED
Step 1 – Carbamate Formation
Ammonia reacts with carbon dioxide under high pressure to form ammonium carbamate.
NH₃ + CO₂ → NH₂COONH₄
(Exothermic reaction)
Step 2 – Dehydration to Urea
Ammonium carbamate is dehydrated to form urea and water.
NH₂COONH₄ → CO(NH₂)₂ + H₂O
(Endothermic reaction)
INDUSTRIAL STEPS TO PRODUCE UREA FERTILIZER
1. AMMONIA AND CO₂ COMPRESSION
-
Ammonia and carbon dioxide are compressed to high pressure
-
Ensures efficient reaction in the synthesis reactor
2. UREA SYNTHESIS (REACTOR STAGE)
-
Compressed NH₃ and CO₂ are fed into a high-pressure reactor
-
Ammonium carbamate forms first
-
Partial conversion to urea occurs
Operating conditions
-
High pressure
-
Elevated temperature
3. STRIPPING AND RECOVERY
-
Unreacted ammonia and CO₂ are removed
-
Stripping gases are recovered and recycled
-
Improves process efficiency and reduces raw material loss
4. UREA SOLUTION CONCENTRATION
-
Urea solution is concentrated by evaporation
-
Water content is reduced
-
Produces molten urea suitable for solidification
5. SOLIDIFICATION (PRILLING OR GRANULATION)
A. Prilling Process
-
Molten urea sprayed from top of a prilling tower
-
Droplets solidify while falling
-
Produces uniform prills
B. Granulation Process
-
Molten urea sprayed onto seed particles in a granulator
-
Granules grow by layering
-
Produces harder, dust-free particles
6. DRYING AND COOLING
-
Removes excess moisture
-
Improves mechanical strength
-
Prevents caking during storage
7. SCREENING
-
Separates on-size product
-
Oversize crushed and recycled
-
Fines returned to granulation
8. COATING (ANTI-CAKING TREATMENT)
-
Applied to prevent lump formation
-
Improves storage stability and flowability
9. PACKAGING AND STORAGE
-
Packed in moisture-proof bags or stored in bulk
-
Stored in dry, ventilated warehouses
