Techniques

Chapter 1: Techniques

Oxidation Powerhouse: How Roxidizers Work

Roxidizers leverage the power of oxidation to break down harmful pollutants. This process involves the addition of oxygen atoms to the molecules of VOCs and air toxics, transforming them into less harmful substances.

There are primarily two oxidation techniques employed in Roxidizers:

1. Thermal Oxidation: This method involves heating the contaminated air stream to a high temperature, typically between 1,500°F and 2,000°F, in a combustion chamber. This high temperature breaks down the VOCs and air toxics into simpler, less harmful molecules, primarily carbon dioxide and water.
2. Catalytic Oxidation: This technique utilizes a catalyst, usually a precious metal like platinum or palladium, to lower the activation energy required for oxidation. The catalyst speeds up the oxidation process at a lower temperature, typically between 600°F and 1,000°F, compared to thermal oxidation. This makes catalytic oxidation more energy-efficient.

The Power of Oxidation: Key Advantages

• High Efficiency: Roxidizers achieve significant reductions in VOC and air toxics emissions.
• Versatility: They can handle a wide range of pollutants, including complex organic compounds.
• Comprehensive Solutions: Roxidizers can be integrated into various systems for complete control of VOC and air toxics emissions.
• Minimized Waste: The process produces primarily harmless byproducts like carbon dioxide and water.

Beyond the Basics: Exploring Variations

Tellkamp Systems, Inc. offers customized Roxidizer solutions, incorporating different design elements to enhance efficiency and address specific needs:

• Regenerative Thermal Oxidizers (RTOs): These systems recover heat from the exhaust stream to preheat the incoming contaminated air, improving energy efficiency.
• Direct Flame Oxidizers (DFOs): Direct flame oxidizers utilize a burner to heat the contaminated air stream, providing a simpler and more cost-effective solution for lower flow rates.
• Catalytic Oxidizers (COs): As mentioned earlier, these systems utilize catalysts to lower the required oxidation temperature, offering energy savings and reducing the overall carbon footprint.
