Shiraz Petrochemical Urea: Applications and Specifications

Applications

Granular Urea

1. Agriculture & Animal Feed:
   • A cost-effective source of fixed nitrogen for fertilizers.
   • Used in animal feed to promote growth.
2. Plastics:
   • Raw material for urea-formaldehyde resin manufacturing.
3. Adhesives:
   • Base material for waterproof glues like urea-formaldehyde or urea-melamine-formaldehyde (used in marine plywood).
4. Deicing:
   • Alternative to rock salt for roadways and runways.
   • Less corrosive to metals compared to salt.
5. Miscellaneous:
   • Flavor enhancer in cigarettes.
   • Browning agent for pretzels.
   • Cosmetics: Ingredient in hair conditioners, facial cleansers, and lotions.
   • First Aid: Used in cold compresses for its endothermic reaction with water.
   • Diesel Exhaust Treatment: Active component in AdBlue and SCR systems.
   • Cloud Seeding: Agent for precipitation.
   • Flame-Proofing Agent.
   • Fuel: Clean-burning fuel for vehicles and engines.
   • NOx Reducer: Reactant in diesel exhaust systems.

Prilled Urea

• Primarily used as a nitrogen-release fertilizer (over 90% of global production).
• Raw material for plastics, adhesives, and industrial feedstock like potassium cyanate.

Specifications

Granular Urea

• Size: 2.40–3.50 mm.
• Strength: 10–17 N (average crushing load).
• Suitable for agricultural and industrial applications.

Prilled Urea

• Size: ~1.60 mm.
• Strength: ~3.80 N (average crushing load).
• Known for uniform size and lower strength, ideal for specific applications.

Product Description

Urea (Prilled and Granular):

• White, spherical solid with 46% nitrogen (amine groups).
• Highly water-soluble and safe for mammals and birds.
• Used in agriculture, forestry, and industrial applications.

Key Considerations for Use

• Decomposes via microorganisms before assimilation by plants (slow-release).
• Handle with care due to its high nitrogen content.

Comparison of Granular and Prilled Urea

Granular urea is mechanically stronger and larger, making it suitable for diverse applications, while prilled urea offers uniform size and lower strength, ideal for specific needs.

Conclusion

Both granular and prilled urea have distinct properties tailored to different applications. Granular urea is more robust and versatile, whereas prilled urea excels in uniformity and specific industrial uses.
