Recuperative Thermal Oxidation RCO

Regenerative Catalytic Oxidation (RCO) is a technology that combines the efficiency of thermal oxidation with a heat recovery system to optimize energy consumption.

This system is especially recommended for industries with contaminated airflows with a high pollutant load that require a sustainable and cost-effective solution.

At BLUER MEDIOAMBIENTE, we develop RCO solutions that minimize environmental impact, reduce energy expenditure, and meet the highest quality and regulatory standards.

What is Recuperative Thermal Oxidation (RCO)?

Recuperative Thermal Oxidation (RCO) is an industrial emissions treatment technology that combines the efficiency of thermal oxidation with a heat recovery system, thereby optimizing energy consumption. It is used primarily to eliminate volatile organic compounds (VOCs) and other gaseous pollutants generated in industrial processes.
Downstream of the oxidation system, and taking advantage of the residual heat in the gases produced by the exothermic oxidation reaction, a heat recovery unit is installed to generate the thermal fluid the client requires—such as steam, hot water, thermal oil, etc.

How does the RCO system work?

The RCO system operates in several stages to ensure effective removal of pollutants and reuse of the heat generated:

Contaminated air inlet: Air containing volatile organic compounds is directed to the oxidation chamber.
Initial heating: A burner is used to raise the temperature of the contaminated air to approximately 750–950°C, ensuring the thermal decomposition of VOCs.
Contaminant oxidation: At high temperatures, VOCs break down into carbon dioxide (CO2) and water vapor (H2O), substances that are less harmful to the environment.
Heat recovery: The heat generated is transferred to a heat exchanger, a thermal oil recovery boiler, hot water, steam, or used to preheat the incoming air, reducing energy consumption.
Clean gas outlet: After oxidation and heat recovery, the treated gases are safely released into the atmosphere.

Advantages of the RCO System

High energy efficiency: Reduces fuel consumption thanks to heat recovery.
Regulatory compliance: Designed to meet the most stringent environmental regulations.
Lower environmental impact: Reduces the emission of pollutants and greenhouse gases.
Reduced operating costs: Leverages recovered heat, lowering energy expenses.
Potential economic payback Payback through more economical generation of the thermal fluid
