The Anguil Catalytic Oxidizer destroys toxic Volatile Organic Compounds (VOCs) that are discharged in industrial process exhausts. The catalytic reactor achieves destruction of the organics by the process of oxidation. The catalyst oxidizes the hydrocarbons to carbon dioxide and water vapor at significantly lower temperatures than thermal oxidizers.

How the Catalytic Oxidizer Works:

The Catalytic Oxidizer is designed based on volume of airflow, organic vapor concentrations and desired destruction efficiency. During operation, VOC-laden air is drawn into the system fan and is discharged into the system's heat exchanger. The air is preheated through the tube side of the heat exchanger and then passes the burner, where the contaminated air is raised to the operating temperature. As the VOC-laden air passes through the catalyst, an exothermic (heat releasing) reaction takes place. The VOCs in the air stream are converted to carbon dioxide and water vapor. The hot, purified air then passes on the shell side of the heat exchanger where the energy released by the reaction is used to preheat the incoming air. The heat exchanger minimizes the system's fuel consumption with the system being self-sustaining at low LEL levels. Finally, the contaminant-free air is exhausted into the atmosphere.
