| RTO (Regenerative Thermal Oxidizer) | ≥99% |
| RCO (Regenerative Catalytic Oxidizer) | ≥98% |
| Zeolite Rotor Concentrator | 90%–99% |
| K-Filter Solvent Recovery System | ≥95% |
| Overall System Efficiency | Up to 99.5% |
Actual efficiency depends on VOC concentration, temperature, humidity, and overall system design.
5. How to Choose the Right VOC Treatment Technology?
Technology selection depends on:
- VOC concentration
- Airflow volume
- Gas composition
- Temperature and humidity
- Safety requirements
- Energy consumption and operating cost
Recommended Selection Logic
High Concentration + Low Airflow
Suitable technologies:
- RTO
- TO
- CO
- RCO
Low Concentration + High Airflow
Suitable technologies:
- Zeolite rotor concentration + RTO
- Adsorption concentration combustion systems
Solvent Recovery Applications
Recommended:
- K-Filter solvent recovery systems
Polymerizable VOCs
Require special engineering design. Zeolite rotors should be carefully evaluated.
Information Required for Quotation
Please provide:
- Airflow volume (m³/h or Nm³/h)
- VOC composition and ratio
- Concentration range
- Temperature and humidity
- Emission standards
The more complete the information, the more accurate the solution.
6. What Is the Difference Between RTO and RCO?
| Comparison | RTO | RCO |
|---|---|---|
| Oxidation Temperature | Around 760°C | 300–550°C |
| Thermal Efficiency | >95% | >95% |
| Removal Efficiency | 99% | 98% |
| Energy Consumption | Low | Lower |
| Open Flame | Yes | No |
| Maintenance Cost | Lower | Higher |
| Applicability | Broad | Requires suitable gas composition |
