High purity industrial Urea Solution stable eco-friendly clean liquid for vehicle exhaust purification and industrial flue gas denitrification widely used in environmental protection industry.

Urea Solution

Introduction

Urea solution is categorized into two core types: Automotive (AUS32) and Industrial Denitration. It is formulated from high-purity urea (≥99.8% purity) and ultrapure water complying with GB/T 20284, mixed in precise ratios. Production strictly adheres to national standards GB 29518-2013 (automotive), GB/T 35595-2017 (industrial), and international ISO 22241, with zero impurity additives. The product features stable purity, low crystallization tendency, and requires only ambient sealed storage. Backed by our nationwide supply chain, we ensure rapid bulk order response, consistent delivery, and long-term usability across scenarios.

Attribute Characteristics

1.Automotive Urea Solution (AUS32): Fixed concentration at 32.5% (AUS32 standard), pH stabilized at 7.5±0.5. Odorless and non-corrosive, it is compatible with all vehicle SCR (Selective Catalytic Reduction) systems. High reaction efficiency rapidly decomposes nitrogen oxides (NOx) in exhaust, enabling vehicles to meet China National VI and higher emission standards, reducing pollution without damaging engines or exhaust components.

2.Industrial Denitration Urea Solution: Customizable concentration (32%–50%) per client requirements. It features qualified purity, uniform composition, no suspended solids or sediment, and strong chemical stability. Designed for industrial flue gas denitration systems, it delivers high efficiency and flexible adjustability for varying flue gas concentrations and throughputs, meeting emission reduction targets.

3.General Properties: Highly water-soluble, non-flammable, non-explosive, and easy to store/transport. Shelf life reaches 12 months under sealed conditions; anti-freezing measures are required below -11°C to prevent crystallization.

Product Technical Features

1.Raw Material Purification Technology: Multi-stage distillation removes impurities (biuret, heavy metals, particulates) from urea, ensuring ≥99.8% purity. Prevents SCR/industrial denitration equipment clogging and extends service life.

2.Precise Proportioning Technology: Automated intelligent blending system controls urea-to-ultrapure water ratio with error ≤±0.5%, ensuring uniform, stable concentration and consistent denitration/exhaust treatment performance.

3.Sterile Production Technology: GMP-class clean workshop with fully sealed manufacturing prevents airborne impurities/microbial contamination. Ensures odorless, sediment-free product compliant with environmental and safety standards.

4.Stability Optimization Technology: Proprietary stabilizers (national standard-compliant) inhibit hydrolysis and crystallization, enhancing storage stability. Maintains performance under extreme high/low temperatures without efficacy loss.

Color & Material

1.Color: Naturally colorless and transparent liquid, free of visible suspended solids or sediment. Slight yellowing (non-purity-affecting) is normal; cloudiness, blackening, or flocculent sediment indicate non-conformance.

2.Packaging Material: Food-grade HDPE (High-Density Polyethylene) containers—corrosion-resistant, impact-resistant, and leak-proof. Prevents water evaporation and contamination. Available in 10L, 20L, 200L drums and bulk tanker shipments for vehicle refueling and industrial bulk use.

3.Auxiliary Materials: Dispensing tools and storage vessels use urea-resistant materials (HDPE, stainless steel) to avoid reactions with ordinary metals that could contaminate the product or damage equipment.

Product Functions

1.Automotive Urea Solution (AUS32): Acts as the reducing agent for SCR systems. Under high temperatures, it catalytically reacts with NOx in exhaust to decompose it into harmless nitrogen (N₂) and water (H₂O). Reduces emissions, eliminates exhaust odor, protects SCR catalysts, and extends exhaust system lifespan.

2.Industrial Denitration Urea Solution: Core function for industrial flue gas denitration. Heated in denitration systems, it decomposes into ammonia (NH₃), which selectively catalyzes reactions with NOx to form N₂ and water. Purifies flue gas, meets industrial emission standards, and reduces air pollution.

3.Additional Benefits: Non-corrosive, non-toxic, and free of secondary pollution. Easy storage and dispensing lower user costs and operational complexity. Industrial-grade customizable concentrations adapt to diverse denitration needs and enhance efficiency.
