Urea Solution 40 Percent
RXSOL-25-1920-1250Application & Usage
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
Procedure
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.
