Chemical Treatment Vocs Regenerative Catalytic Combustion RCO for Coating

Automatic VOC Abatement System with Regenerative Catalytic Oxidizer (RCO)

This advanced system is engineered to effectively eliminate volatile organic compounds (VOCs) generated from industrial production processes. It ensures all exhaust gases are purified to meet environmental emission standards. The system integrates a dry filtration unit, an adsorption module, and a catalytic oxidation chamber to achieve continuous, energy-efficient waste gas treatment.

Technical Overview

1. Fully Automated VOC Purification
The system operates under a fully automated desorption and regeneration cycle, providing continuous VOC removal without generating secondary pollutants. Automated monitoring ensures stable, efficient, and environmentally safe operation.

2. Dual-Stage Pre-Filtration
Incoming exhaust air passes through a two-level dry filtration system that removes dust and solid impurities before entering the adsorption bed. This process enhances adsorption performance and extends the service life of the adsorbent materials.

3. High-Efficiency Adsorption Bed
The system utilizes honeycomb-structured activated carbon or zeolite molecular sieve media, featuring up to 8–10 times greater density compared to conventional fiber-type adsorbents.
Performance highlights:

• Adsorption capacity up to 25% of media weight before regeneration

• Extended operational lifespan

• Low resistance for efficient airflow

• High VOC capture efficiency

4. Catalytic Oxidation Chamber
Equipped with a precious metal catalyst (Pd/Pt) supported on a ceramic honeycomb substrate, the oxidation unit offers:

• Low ignition temperature and rapid heat-up response

• Stable thermal conversion and high catalytic activity

• Energy-efficient operation through heat retention

• Long catalyst service life and excellent thermal stability

The system achieves self-sustaining combustion at VOC concentrations ≥2000 ppm and maintains a destruction efficiency above 97%.

5. Integrated Heat Recovery System
A closed-loop thermal recovery network reuses waste heat from the oxidation chamber for the desorption process, minimizing external energy consumption. Concentrated VOCs are redirected to the oxidizer for complete treatment, significantly reducing operational energy costs.

6. Intelligent PLC Control
The entire process is governed by a programmable logic controller (PLC) with:

• Automatic temperature regulation

• Timed desorption sequencing

• Real-time feedback monitoring and safety protection

This ensures safe, stable, and fully automated system performance with minimal operator involvement.

In summary, the Regenerative Catalytic Oxidizer (RCO) system provides a highly efficient, energy-saving, and eco-friendly solution for VOC treatment—offering long-term reliability, reduced maintenance, and compliance with the most stringent environmental standards.
