DeNOx Reducing Agents are high-purity stable and efficient chemicals for industrial flue gas denitrification exhaust treatment and major environmental protection engineering projects.

DeNOx Reducing Agents

Introduction:

DeNOx reducing agents are the core consumables in industrial flue gas denitrification, encompassing three major categories: liquid ammonia, ammonia water, and urea-based products. We can customize concentrations to meet customers’ SCR (Selective Catalytic Reduction) and SNCR (Selective Non-Catalytic Reduction) process requirements, ensuring precise alignment with the operational conditions of various applications. Our products offer high denitrification efficiency, strictly controlled ammonia slip rates, and strong chemical stability. The production process strictly adheres to relevant national and industry standards, ensuring high purity, uniform composition, and the absence of harmful impurities. Backed by our comprehensive production system and quality control measures, we guarantee stable and reliable product performance, helping industrial enterprises efficiently complete flue gas denitrification tasks and mitigate environmental compliance risks.

Product Features:

Wide Applicability: Suitable for flue gas denitrification applications across multiple industries, including power generation, steel, chemicals, metallurgy, and building materials. It flexibly adapts to both SCR and SNCR—the two mainstream denitrification processes—without requiring large-scale modifications to existing equipment, resulting in low adaptation costs.

Stable Performance: Denitrification efficiency reaches over 85%, with ammonia slip controlled below 3 ppm. The product exhibits strong chemical stability, resisting decomposition and deterioration during storage and transportation, and maintains excellent denitrification performance over the long term.

Safe and Environmentally Friendly: The product complies with industry environmental and safety standards, contains no toxic or harmful components, and does not generate secondary pollution during use. Leveraging our company’s technical expertise, we provide comprehensive safety guidance to ensure the stable operation of the denitrification system.

Convenient Customization: Drawing on our company’s technical capabilities, we can customize specific concentrations and specifications based on customer requirements such as denitrification processes, flue gas concentration, and treatment capacity. We also provide accompanying technical support to resolve any issues that may arise during use.

Product Technical Features:

Precision Blending Technology: Utilizing an automated intelligent blending system, we precisely adjust the concentration of the reducing agent according to customer process requirements, with a blending error of ≤±0.5%. This ensures uniform and stable concentration, preventing any impact on denitrification efficiency caused by concentration deviations.

Purity Control Technology: Utilizing multi-stage distillation and purification processes, we remove impurities (such as heavy metals, particulates, and harmful residues) from raw materials. This ensures product purity meets standards, prevents impurities from clogging denitrification equipment or affecting catalyst activity, and extends equipment service life.

Ammonia Slip Control Technology: Incorporates specialized controlled-release components and process-optimized formulations to effectively control ammonia slip rates. This prevents equipment corrosion and secondary pollution caused by ammonia slip, ensuring the long-term stable operation of the denitrification system.

Stability Optimization Technology: Adds industry-standard stabilizers to inhibit the hydrolysis and decomposition of the reductant, enhancing product storage and usage stability. The formulation is adapted to complex operating conditions—including high and low temperatures and varying humidity levels—to ensure consistent denitrification performance.

Process Adaptation Technology: Formulations are optimized to address the distinct characteristics of SCR and SNCR processes, ensuring perfect compatibility between the reductant and the process. This enhances denitrification efficiency, reduces energy consumption, and helps enterprises lower operating costs.

Product Color and Materials:

Product Color: Each of the three major product categories has distinct characteristics. Liquid ammonia is a colorless, transparent liquid with no visible suspended solids; ammonia water is a colorless to pale yellow transparent liquid with no sediment or flocculent matter; urea-based reductants (solution type) are colorless, transparent liquids; slight yellowing does not affect performance. Turbidity, blackening, or flocculent sedimentation are strictly prohibited (such products are considered non-conforming).

Packaging Materials: Special corrosion-resistant materials are used. Liquid ammonia and ammonia water are packaged in high-pressure steel cylinders (compliant with GB 5099 standards) or specialized corrosion-resistant storage tanks. Urea-based reducing agents are packaged in food-grade HDPE (high-density polyethylene) containers, which are corrosion-resistant, impact-resistant, and highly airtight, effectively preventing leaks and contamination.

Auxiliary Materials: All accompanying storage containers and dispensing tools are made of materials resistant to corrosion by reducing agents (such as stainless steel or specialized corrosion-resistant HDPE) to prevent ordinary metals from reacting with the reducing agents, which could contaminate the product or damage equipment.

Product Features

Core Function: As a key consumable in industrial flue gas denitrification systems, this product works in conjunction with the denitrification system to convert nitrogen oxides (NOx) in flue gas into harmless nitrogen (N₂) and water (H₂O), thereby purifying the flue gas and helping enterprises meet environmental emission standards.

Supporting Functions: Stabilizes the operation of the denitrification system, reduces wear and clogging of denitrification equipment, and extends the service life of both the equipment and the catalyst; through precise controlled release, it minimizes the risk of equipment corrosion caused by ammonia slip, thereby reducing corporate equipment maintenance costs.

Customization: We can tailor the concentration and packaging specifications to meet specific customer process requirements, flue gas concentrations, and treatment capacities. We also provide technical guidance to optimize denitrification solutions, enhance denitrification efficiency, and reduce operational energy consumption.
