1. Market Background

As a global hub for the metallurgical industry, Russia produces vast amounts of complex exhaust gases from steelmaking, coking, and non-ferrous smelting. With tightening local environmental regulations, metallurgical enterprises must not only achieve compliant NOx emissions but also effectively treat residual Volatile Organic Compounds (VOCs). Maintaining long-term stability of catalytic systems under extreme cold conditions and high dust concentrations is a primary pain point for clients in this region.

2. Customer & Application Scenario

The client in this case is a leading Metallurgical Industry enterprise in Russia, whose production lines discharge flue gas containing medium-to-high concentrations of NOx and complex organic components. The application involves end-of-pipe treatment for high-temperature smelting furnaces. The client required a composite aftertreatment system capable of handling both VOCs and NOx, demanding catalysts with superior anti-poisoning capabilities and mechanical strength to support high-load industrial production.

3. Our Solution

To address Russian metallurgical conditions, we provided a parameterized VOC + SCR integrated catalytic solution, achieving deep purification through multi-stage catalytic reactions.

Key Technical Parameters:

• SCR (Selective Catalytic Reduction Catalyst): Utilizes an SCR Catalyst with wide temperature window characteristics to ensure high DeNOx efficiency under complex flue gas conditions.

• VOC Catalyst: Employs high-performance VOC Catalysts to completely convert organic pollutants into CO2 and H2O through catalytic oxidation.

• Operational Stability: The system design accounts for the anti-dust and anti-poisoning requirements of Industrial Exhaust Gas Treatment, ensuring no significant performance degradation of the catalyst substrate over long operational cycles.

• Synergistic Control: Optimized reactor layout enables effective thermal energy utilization, reducing overall system energy consumption.

4. Customer Feedback & Summary

Feedback indicates that the system performed stably during the extreme Russian winter, with all indicators exceeding local environmental compliance requirements. Its high conversion efficiency and reliable substrate lifespan significantly reduced unscheduled downtime and maintenance costs.

Summary: By delivering precise VOC + SCR technical integration in the Industrial Exhaust Gas Treatment sector, we successfully resolved complex emission challenges for the Russian Metallurgical Industry. This project demonstrates our technical advantages in treating exhaust under harsh conditions and reinforces our professional standing in the global industrial catalysis market.
