Nitrogen Oxide(NOx )Treatment System
The NOx treatment system is specialized equipment designed for the highly efficient purification of nitrogen oxides (NOx) in industrial exhaust gases, utilizing absorption and reduction technologies.
Application Scenarios: It is suitable for treating NOx-containing exhaust gases in the metallurgical and chemical industries, handling flow rates ranging from hundreds to tens of thousands of cubic meters per hour with varying gas compositions and concentrations. For applications involving extremely high gas volumes, a parallel system configuration can be employed.
Product Description
We provide highly efficient and cost-effective solutions for treating nitrogen oxide (NOx) emissions generated by industries such as non-ferrous metallurgy and chemical manufacturing. Our systems utilize absorption and reduction technologies specifically designed to purify industrial exhaust gases; they achieve absorption efficiencies of up to 99.99% and ensure NOx emission concentrations remain at or below 100 mg/m³. The core equipment is corrosion-resistant and offers a service life of over eight years.
These NOx treatment systems are specialized units that employ absorption and reduction technologies for the efficient purification of nitrogen oxides (NOx) in industrial exhaust. They are suitable for treating NOx-containing exhaust gases across the metallurgical and chemical sectors, handling flow rates ranging from hundreds to tens of thousands of cubic meters per hour with varying gas compositions and concentrations. For applications requiring exceptionally high flow rates, multiple units can be operated in parallel to meet the demand.
Processing Workflow
Key Features

Stability and Reliability: Features a high degree of automation and adaptability to various operating conditions, ensuring stable long-term performance and helping clients easily pass environmental compliance inspections.
Primary Reaction Mechanisms
NO + Reducing Agent → N₂↑ + CO₂↑ + H₂O (Catalytic conditions)
NO₂ + Reducing Agent → N₂↑ + CO₂↑ + H₂O (Catalytic conditions)
NO + NO₂ → N₂O₃
N₂O₃ + H₂O → 2HNO₂
HNO₂ + Reducing Agent → N₂↑ + CO₂↑ + H₂O
NOx Treatment System Technical Advantages
1. Primary Reaction Mechanisms
The process generates no polluted wastewater or solid waste; the reaction yields only nitrogen, CO2, and water. With no secondary pollution, it achieves true zero-pollution, zero-emission operation.
2. High Absorption Efficiency and Compliance
Absorption efficiency reaches up to 99.99%, with NOx emission concentrations ≤100 mg/m³.
3. Low Investment and Operating Costs
The process flow is streamlined, with NOx gases fed directly into the treatment unit, resulting in low energy consumption. It features a compact footprint and utilizes a single reducing agent, ensuring low investment and operating costs.
4. High Integration and Operational Flexibility
Equipped with an intelligent control system and touchscreen interface, the unit allows for independent control. Maintenance can be performed without shutting down the entire system, ensuring continuous absorption and treatment.
5. Long Service Life
Corrosion-resistant and durable; the main equipment has a service life of over eight years.
