SCR System Diesel Exhaust Fluid Production Used Solid Pure Urea

used in selective catalytic reduction (SCR) systems in diesel engines. It is designed to reduce harmful nitrogen oxide (NOx) emissions from diesel vehicles.

Automotive-grade urea is a highly purified solution of urea dissolved in demineralized water. It is non-toxic, non-flammable, and safe to handle. The urea solution is injected into the vehicle's exhaust system, where it undergoes a chemical reaction with the hot exhaust gases.

Inside the SCR catalyst, the urea solution breaks down into ammonia (NH3) and carbon dioxide (CO2). The ammonia reacts with the NOx emissions, converting them into nitrogen (N2) and water vapor (H2O), which are harmless components of the air we breathe.

Look for suppliers that adhere to ISO 22241 standards. This ensures that prilled urea you purchase meets the necessary purity and quality requirements.

2. Certification and Compliance: For example, in Europe, DEF must meet the DIN 70070 standard. and do they have the REACHE certificate that required in Europe market.

3. Supply Chain Capability: They should have the capacity to provide a consistent and uninterrupted supply of Automotive urea to meet your requirements.

4. Pricing and Contracts: Compare prices from different suppliers, but also consider the overall value provided.

1. Reduced Effectiveness: Inferior urea may not have the same purity or quality standards as automotive-grade urea. This can result in a lower conversion efficiency of nitrogen oxide (NOx) emissions in the selective catalytic reduction (SCR) system. As a result, the vehicle's emissions may not be effectively reduced, potentially leading to environmental non-compliance or failing emission standards.

2. Damaged SCR System: Low-quality urea can contain impurities or contaminants that can cause damage to the SCR system components. These impurities can clog or foul the SCR catalyst, reducing its effectiveness and potentially leading to costly repairs or replacements.

3. Increased Maintenance Costs: Inferior urea can lead to more frequent clogging or malfunctioning of the SCR system, requiring more frequent maintenance and cleaning procedures. This can result in increased maintenance costs and downtime for the vehicle.

4. Risk of Engine Performance Issues: Poor-quality urea may contain higher levels of impurities that can adversely affect the engine's performance. This can result in decreased fuel efficiency, power loss, or other engine-related issues, reducing
overall vehicle performance.

5. Release of Harmful Emissions: If impure urea is used, it can lead to the release of harmful ammonia (NH3) or other byproducts into the exhaust system. These emissions can contribute to air pollution and negate the purpose of using SCR technology to reduce harmful emissions.
