Urea Solution 40%
Product Description
Urea Solution 40% is a clear, homogeneous aqueous solution containing approximately 40% by weight urea dissolved in water. It provides a convenient liquid source of urea for industrial applications where accurate dosing, rapid mixing and elimination of solid-urea handling are desirable.
The product can be used in industrial chemical processing, NOx-control systems, process-water applications and other formulations requiring a controlled concentration of urea.
Chemical Name: Urea
Formula: CH₄N₂O
CAS No.: 57-13-6
Concentration: 40% w/w Urea
Application
Applications
Urea Solution 40% may be used for:
- NOx reduction and emission-control systems
- Selective Non-Catalytic Reduction (SNCR) processes
- Suitable Selective Catalytic Reduction (SCR) systems designed for aqueous urea
- Industrial chemical manufacturing
- Process chemical formulations
- Nitrogen-source applications
- Industrial wastewater-treatment processes where urea is required as a nutrient
- Controlled liquid dosing systems
Dosage
NOx Reduction
Urea solutions can be used as a reagent in appropriately designed industrial NOx-control systems. Under controlled operating conditions, urea ultimately provides ammonia species that react with nitrogen oxides to form primarily nitrogen and water.
The correct concentration, injection rate, temperature window and atomization conditions depend on the specific SCR/SNCR system and equipment design.
Important: 40% urea solution should not be represented as AdBlue/DEF/AUS 32. Automotive DEF is a standardized 32.5% high-purity urea solution, whereas this product contains approximately 40% urea.
